open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
kill.
3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
skin or wet clothing. Wear dry, hole-free
gloves to insulate hands.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:

ventilation and/or exhaust at the arc to keep
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and below Threshold Limit Values (TLV)
using local exhaust or mechanical ventilation. In
confined spaces or in some circumstances, outdoors, a
respirator may be required. Additional precautions are
also required when welding on galvanized steel.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
5.b. Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors to
form phosgene, a highly toxic gas, and other irritating pro-
ducts.
3.f. Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
5.c. Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation,
especially in confined areas, to insure breathing air is safe.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.
5.d. Read and understand the manufacturer’s instructions for this
equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your
employer’s safety practices. MSDS forms are available from
your welding distributor or from the manufacturer.
3.i. When working above floor level, use a safety belt to protect
yourself from a fall should you get a shock.

SAFETY
WELDING SPARKS can
cause fire or explosion.
CYLINDER may explode
if damaged.
6.a. Remove fire hazards from the welding area.
If this is not possible, cover them to prevent
7.a. Use only compressed gas cylinders
containing the correct shielding gas for the
the welding sparks from starting a fire.
Remember that welding sparks and hot
materials from welding can easily go through small cracks
and openings to adjacent areas. Avoid welding near
hydraulic lines. Have a fire extinguisher readily available.
process used and properly operating
regulators designed for the gas and
pressure used. All hoses, fittings, etc. should be suitable for
the application and maintained in good condition.
7.b. Always keep cylinders in an upright position securely
chained to an undercarriage or fixed support.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
7.c. Cylinders should be located:
•Away from areas where they may be struck or subjected to
physical damage.
6.c. When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact
can cause overheating and create a fire hazard.
•A safe distance from arc welding or cutting operations and
any other source of heat, sparks, or flame.
7.d. Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
6.d. Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause flammable or toxic vapors from substances
inside. They can cause an explosion even though they have
been “cleaned”. For information, purchase “Recommended
Safe Practices for the Preparation for Welding and Cutting of
Containers and Piping That Have Held Hazardous
Substances”, AWS F4.1 from the American Welding Society
(see address above).
7.e. Keep your head and face away from the cylinder valve outlet
when opening the cylinder valve.
7.f. Valve protection caps should always be in place and hand
tight except when the cylinder is in use or connected for
use.
7.g. Read and follow the instructions on compressed gas
cylinders, associated equipment, and CGA publication P-l,
“Precautions for Safe Handling of Compressed Gases in
Cylinders,” available from the Compressed Gas Association
1235 Jefferson Davis Highway, Arlington, VA 22202.
6.e. Vent hollow castings or containers before heating, cutting or
welding. They may explode.
6.f. Sparks and spatter are thrown from the welding arc. Wear oil
free protective garments such as leather gloves, heavy shirt,
cuffless trousers, high shoes and a cap over your hair. Wear
ear plugs when welding out of position or in confined places.
Always wear safety glasses with side shields when in a
welding area.
FOR ELECTRICALLY
powered equipment.
6.g. Connect the work cable to the work as close to the welding
area as practical. Work cables connected to the building
framework or other locations away from the welding area
increase the possibility of the welding current passing
through lifting chains, crane cables or other alternate cir-
cuits. This can create fire hazards or overheat lifting chains
or cables until they fail.
8.a. Turn off input power using the disconnect
switch at the fuse box before working on
the equipment.
8.b. Install equipment in accordance with the U.S. National
Electrical Code, all local codes and the manufacturer’s
recommendations.
6.h. Also see item 1.c.
8.c. Ground the equipment in accordance with the U.S. National
Electrical Code and the manufacturer’s recommendations.

SAFETY
PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions
et les précautions de sûreté specifiques qui parraissent dans ce
manuel aussi bien que les précautions de sûreté générales suiv-
antes:
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de lev-
age, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une grande
partie du corps peut être en contact avec la masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder
parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les vapeurs
du solvant pour produire du phosgéne (gas fortement toxique)
ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
2. Dans le cas de travail au dessus du niveau du sol, se protéger
contre les chutes dans le cas ou on recoit un choc. Ne jamais
enrouler le câble-électrode autour de n’importe quelle partie
du corps.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du ray-
onnement de l’arc et des projections quand on soude ou
quand on regarde l’arc.
1. Relier à la terre le chassis du poste conformement au code de
l’électricité et aux recommendations du fabricant. Le dispositif
de montage ou la piece à souder doit être branché à une
bonne mise à la terre.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
2. Autant que possible, I’installation et l’entretien du poste seront
effectués par un électricien qualifié.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
3. Avant de faires des travaux à l’interieur de poste, la debranch-
er à l’interrupteur à la boite de fusibles.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection libres
de l’huile, tels que les gants en cuir, chemise épaisse, pan-
talons sans revers, et chaussures montantes.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.

SAFETY PRECAUTIONS
The RANGER 305D weighs approximately
775lbs.(352kg.) with a full tank of fuel. A lift bail is
mounted to the machine and should always be used
when lifting the machine.
WARNING
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturer’s
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating and maintenance instructions,
and parts lists.
WARNING
• Lift only with equipment of ade-
quate lifting capacity.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Be sure machine is stable when lift-
• Do not touch electrically live parts or
electrode with skin or wet clothing.
ing.
• Do not lift this machine using lift
bail if it is equipped with a heavy
accessory such as trailer or gas
cylinder.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
-------------------------------------------------------
FALLING
• Do not lift machine if lift bail is
damaged.
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
EQUIPMENT can
cause injury.
• Do not operate machine while
suspended from lift bail.
------------------------------------------------------
--------------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
HIGH ALTITUDE OPERATION
At higher altitudes, output derating may be necessary. For max-
imum rating, derate the machine 2.5% to 3.5% for every 1000 ft.
(305m). Due to new EPA and other local emissions regulations,
modifications to the engine for high altitude are restricted within
the United States and some other European Countries. Use
above 6000 ft.(1828 m) may be limited due to poor engine per-
formance or excessive exhaust smoke. An authorized Kubota
engine field service shop should be contacted to determine if
any adjustments can be made for operation in higher elevations
locally.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at
front of this operator’s manual.
Only qualified personnel should install,
use, or service this equipment.
LOCATION AND VENTILATION
HIGH TEMPERATURE OPERATION
At temperatures above104°F (40°C), output derating is neces-
sary. For maximum output ratings, derate the welder output 2
volts for every 50°F(10°C) above 104°F (40°C).
The welder should be located to provide an unrestrict-
ed flow of clean, cool air to the cooling air inlets and to
avoid restricting the cooling air outlets. Also, locate the
welder so that the engine exhaust fumes are properly
vented to an outside area.
Cold weather starting:
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about 5°F (-15°C). If the engine must be frequently
started at or below 23°F (-5°C), it may be desirable to
install cold-starting aides. The use of No. 1D diesel
fuel is recommended in place of No. 2D at tempera-
tures below 23°F (-5°C). Allow the engine to warm up
before applying a load or switching to high idle.
Note: Extreme cold weather starting may require
longer glow plug operation.
STACKING
RANGER 305D machines cannot be stacked.
ANGLE OF OPERATION
Engines are designed to run in the level condition
which is where the optimum performance is achieved.
The maximum angle of continuous operation is 20
degrees in all directions, 35 degrees Intermittent (less
than 10 minutes continuous) in all directions. If the
engine is to be operated at an angle, provisions must
be made for checking and maintaining the oil level at
the normal (FULL) oil capacity in the crankcase.
WARNING
Under no conditions should ether or other starting
fluids be used with this engine!
------------------------------------------------------------------------
When operating the welder at an angle, the effective
fuel capacity will be slightly less than the specified 12
gallons (45ltrs.).

INSTALLATION
The oil change interval is dependent on the quality of
the oil and the operating environment. Refer to the
Engine Operator’s Manual for more details on the
proper service and maintenance intervals.
TOWING
The recommended trailer for use with this equipment for road,
in-plant and yard towing by a vehicle(1) is Lincoln’s K957-1. If
the user adapts a non-Lincoln trailer, he must assume responsi-
bility that the method of attachment and usage does not result
in a safety hazard nor damage the welding equipment. Some of
the factors to be considered are as follows:
FUEL
USE DIESEL FUEL ONLY
1. Design capacity of trailer vs. weight of Lincoln equipment and
likely additional attachments.
2. Proper support of, and attachment to, the base of the weld-
ing equipment so there will be no undue stress to the frame-
work.
3. Proper placement of the equipment on the trailer to insure
stability side to side and front to back when being moved
and when standing by itself while being operated or ser-
viced.
WARNING
• Fill the fuel tank with clean, fresh fuel. The
capacity of the tank is 12 gals. (45.4ltrs). When
the fuel gauge reads empty the tank contains
approximately 2 gals. (7.6ltrs.) of reserve fuel.
NOTE: A fuel shut off valve is located on the pre-
filter/sediment filter. Which should be in
the closed position when the welder is not
ran for extended periods of time.
4. Typical conditions of use, i.e., travel speed; roughness of sur-
face on which the trailer will be operated; environmental con-
ditions; like maintenance.
------------------------------------------------------------------------
ENGINE COOLING SYSTEM
(1)
5. Conformance with federal, state and local laws.
(1) Consult applicable federal, state and local laws regarding specific requirements for use on public high-
ways.
CAUTION
VEHICLE MOUNTING
Air to cool the engine is drawn in the base sides
and exhaust through radiator & case back. It is
important that the intake and exhaust air is not
restricted. Allow a minimum clearance of 2 feet

INSTALLATION
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must be grounded to the frame of the welder using a
grounded type plug or be double insulated.
SPARK ARRESTER
Some federal, state or local laws may require that
gasoline or diesel engines be equipped with exhaust
spark arresters when they are operated in certain
locations where unarrested sparks may present a fire
hazard. The standard muffler included with this welder
does not qualify as a spark arrester. When required by
local regulations, a suitable spark arrester, such as
the K1898-1 must be installed and properly main-
tained.
When this welder is mounted on a truck or trailer, its
frame must be electrically bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connect-
ed between the machine grounding stud and the
frame of the vehicle. When this engine driven welder
is connected to premises wiring such as that in a
home or shop, its frame must be connected to the sys-
tem earth ground. See further connection instructions
in the section entitled "Standby Power Connections"
as well as the article on grounding in the latest
National Electrical Code and the local code.
CAUTION
An incorrect spark arrestor may lead to damage to
the engine or adversely affect performance.
------------------------------------------------------------------------
REMOTE CONTROL
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded. Do not ground the
machine to a pipe that carries explosive or com-
bustible material.
The RANGER 305D is equipped with a 6-pin and a
14-pin connector. The 6-pin connector is for connect-
ing the K857 or K857-1 Remote Control or for TIG
welding, the K870 foot Amptrol or the K936-2 hand
Amptrol. When in the CC-STICK, DOWNHILL PIPE,
or CV-WIRE modes and when a remote control is
connected to the 6-pin Connector, the auto-sensing
circuit automatically switches the OUTPUT control
from control at the welder to remote control.
The National Electrical Code lists a number of alter-
nate means of grounding electrical equipment. A
machine grounding stud marked with the symbol
is provided on the front of the welder.
When in TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.
WELDING TERMINALS
The RANGER 305D is equipped with a toggle switch
for selecting "hot" welding terminal when in the "WELD
TERMINALS ON" position or "cold" welding terminal
when in the "REMOTELY CONTROLLED" position.
The 14-pin connector is used to directly connect a
wire feeder control cable. In the CV-WIRE mode,
when the control cable is connected to the 14-pin con-
nector, the auto-sensing circuit automatically makes
the Output Control inactive and the wire feeder volt-
age control active
WELDING OUTPUT CABLES
With the engine off connect the electrode and work
cables to the output studs. The welding process dic-
tates the polarity of the electrode cable. These con-
nections should be checked periodically and tightened
with a 3/4" wrench.
WARNING
NOTE: When a wire feeder with a built in welding
voltage control is connected to the 14-pin connec-
tor, do not connect anything to the 6-pin connec-
tor.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.

CABLE INSTALLATION
Install the welding cables to your RANGER 305D as
follows.
STANDBY POWER CONNECTIONS
1. The diesel engine must be OFF to install welding
cables.
The RANGER 305D is suitable for temporary, stand-
by or emergency power using the engine manufactur-
er’s recommended maintenance schedule.
2. Remove the flanged nuts from the output terminals
.
3. Connect the electrode holder and work cables to the
weld output terminals. The terminals are identified
on the case front.
The RANGER 305D can be permanently installed as
a standby power unit for 240 VAC, 3 wire, single
phase, 44 amp service. Connections must be made
by a licensed electrician who can determine how the
120/240 VAC power can be adapted to the particular
installation and comply with all applicable electrical
codes.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the
“work”) is properly connected to the work clamp and
cable.
• Install the double-pole, double-throw switch
between the power company meter and the premis-
es disconnect. Switch rating must be the same or
greater than the customer’s premises disconnect
and service over current protection.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
• Take necessary steps to assure load is limited to
the capacity of the RANGER 305D by installing a
50 amp, 240 VAC double pole circuit breaker.
Maximum rated load for each leg of the 240 VAC
auxiliary is 44 amperes. Loading above the rated
output will reduce output voltage below the allow-
able - 10% of rated voltage which may damage
appliances or other motor-driven equipment and
may result in overheating of the RANGER 305D
engine and/or alternator windings.
• Do not cross the welding cables at the output ter-
minal connection. Keep the cables isolated and
separate from one another.
------------------------------------------------------------------------
AUXILIARY POWER RECEPTACLES

two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.
• Install a 50 amp, 120/240 VAC plug (NEMA Type
14-50) to the double-pole circuit breaker using No.
6, 4 conductor cable of the desired length. (The 50
amp, 120/240 VAC plug is available in the optional
K802R plug kit or as part number T12153-9.)
The auxiliary power capacity is 10,500 watts Peak,
10000 Watts Continuous of 60 Hz, single phase power.
The auxiliary power capacity rating in watts is equiva-
lent to volt-amperes at unity power factor. The max
permissible current of the 240 VAC output is 44 amps.
• Plug this cable into the 50 Amp, 120/240 Volt
receptacle on the RANGER 305D case front.

GENERAL DESCRIPTION
BREAK-IN PERIOD
The RANGER 305D is a diesel engine powered DC multi-
process welding power source and 120 / 240 volt AC power
generator. The engine drives a generator that supplies three
phase power for the DC welding circuit and single phase
power for the AC auxiliary outlets. The DC welding control
system uses state of the art Chopper Technology (CT tm)
for superior welding performance.
Lincoln Electric selects high quality, heavy-duty industrial
engines for the portable welding machines we offer. While it is
normal to see a small amount of crankcase oil consumption
during initial operation, excessive oil use, wetstacking (oil or tar
like substance at the exhaust port), or excessive smoke is not
normal.
Larger machines with a capacity of 350 amperes and higher,
which are operated at low or no-load conditions for extended
periods of time are especially susceptible to the conditions
described above. To accomplish successful engine break-in,
most diesel-powered equipment needs only to be run at a rea-
sonably heavy load within the rating of the welder for some
period of time during the engine’s early life. However, if the
welder is subjected to extensive light loading, occasional mod-
erate to heavy loading of the engine may sometimes be neces-
sary. Caution must be observed in correctly loading a
diesel/generator unit.
FOR AUXILIARY POWER:
Start the engine and set the IDLER control switch to the
desired operating mode. Full power is available regardless
of the welding control settings providing no welding current
is being drawn.
The auxiliary power of the RANGER 305D consists of two
20 Amp-120 VAC (5-20R) duplex receptacles and one 50
Amp 120/240 VAC (14-50R) receptacle. The 240 VAC
receptacle can be split for single phase 120 VAC operation.
1. Connect the welder output studs to a suitable resistive load
bank. Note that any attempt to short the output studs by
connecting the welding leads together, direct shorting of the
output studs, or connecting the output leads to a length of
steel will result in catastrophic damage to the generator and
voids the warranty.
2. Set the welder controls for an output current and voltage
within the welder rating and duty cycle. Note that any
attempt to exceed the welder rating or duty cycle for any
period of time will result in catastrophic damage to the gen-
erator and voids the warranty.
ENGINE OPERATION
Before Starting the Engine:
• Be sure the machine is on a level surface.
• Open top & side engine doors and remove the engine oil
dipstick and wipe it with a clean cloth. Reinsert the dip-
stick and check the level on the dipstick.
• Add oil (if necessary) to bring the level up to the full mark.
Do not overfill. Close engine door.
• Check radiator for proper coolant level. (Fill if necessary).
• See Engine Owner’s Manual for specific oil and coolant
recommendations.
3. Periodically shut off the engine and check the crankcase oil
level.

WELDING CONTROLS (Figure B.1)
2. DIGITAL OUTPUT METERS
The digital meters allow the output voltage (CV-WIRE
mode) or current (CC-STICK, PIPE and TIG modes)
to be set prior to welding using the OUTPUT control
dial. During welding, the meter display the actual out-
put voltage (VOLTS) and current (AMPS). A memory
feature holds the display of both meters on for seven
seconds after welding is stopped. This allows the
operator to read the actual current and voltage just
prior to when welding was ceased.
1. OUTPUT CONTROL: The OUTPUT dial is
used to preset the output voltage or current as dis-
played on the digital meters for the four welding
modes. When in the CC-STICK, DOWNHILL PIPE or
CV-WIRE modes and when a remote control is con-
nected to the 6-Pin or 14-Pin Connector, the auto-
sensing circuit automatically switches the OUTPUT
CONTROL from control at the welder to the remote
control.
While the display is being held the left-most decimal
point in each display will be flashing. The accuracy of
the meters is +/- 3%.
In the CV-WIRE mode, when the wire feeder control
cable is connected to the 14-Pin Connector, the auto-
sensing circuit automatically makes OUTPUT CON-
TROL inactive and the wire feeder voltage control
active.
3. WELD MODE SELECTOR SWITCH:
(Provides four selectable welding modes)
CV-WIRE
DOWNHILL PIPE
CC-STICK
TOUCH START TIG
When in the TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current

OPERATION
4. ARC CONTROL: The ARC CONTROL dial is
active in the CV-WIRE, CC-STICK and DOWNHILL PIPE
modes, and has different functions in these modes. This
control is not active in the TIG mode.
ENGINE CONTROLS: (Figure B.2)
CC-STICK mode: In this mode, the ARC CONTROL dial
sets the short circuit current (arc-force) during stick welding
to adjust for a soft or crisp arc. Increasing the dial from –10
(soft) to +10 (crisp) increases the short circuit current and
prevents sticking of the electrode to the plate while welding.
This can also increase spatter. It is recommended that the
ARC CONTROL be set to the minimum number without
electrode sticking. Start with a setting at 0.
FIGURE B.2
11. RUN/STOP SWITCH - RUN position ener-
gizes the engine prior to starting. STOP position stops
the engine. The oil pressure interlock switch prevents
battery drain if the switch is left in the RUN position
and the engine is not operating.
DOWNHILL PIPE mode: In this mode, the ARC CONTROL
dial sets the short circuit current (arc-force) during stick
welding to adjust for a soft or a more forceful digging arc
(crisp). Increasing the number from –10 (soft) to +10 (crisp)
increases the short circuit current which results in a more
forceful digging arc. Typically a forceful digging arc is pre-
ferred for root and hot passes. A softer arc is preferred for
fill and cap passes where weld puddle control and deposi-
tion ("stacking" of iron) are key to fast travel speeds. It is
recommended that the ARC CONTROL be set initially at 0.
12. GLOW PLUG PUSH BUTTON -
When pushed activates the glow plugs as well as the
electric fuel pump for quick starting. Glow plug should
not be activated for more then 20 seconds continu-
ously.
CV-WIRE mode: In this mode, turning the ARC CONTROL
clock wise from –10 (soft) to +10 (crisp) changes the arc
from soft and washed-in to crisp and narrow. It acts as an
inductance/pinch control. The proper setting depends
on the procedure and operator preference. Start with
a setting of 0.
AUTO BLEED FUNCTION – Air will automatically
bleed from the fuel system by simply pushing the
GLOW PLUG BUTTON. It is generally not required
to crack open fittings in the fuel system to bleed air
from the fuel system.
13. START PUSH BUTTON -
Energizes the starter motor to crank
the engine.
5. WELD OUTPUT TERMINALS WITH
FLANGE NUT: Provides a connection point for the
electrode and work cables.
14. IDLER SWITCH- Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
6. GROUND STUD: (graphic)
Provides a connection point for connecting the
machine case to earth ground.
2) In the AUTO position, the idler operates as follows:
• When switched from HIGH to AUTO or after start-
ing the engine, the engine will operate at full speed
for approximately 12 seconds and then go to low
idle speed.
• When the electrode touches the work or power is
drawn for lights or tools (approximately 100 Watts
minimum), the engine accelerates and operates at
full speed.
• When welding ceases or the AC power load is
turned off, a fixed time delay of approximately 12
seconds starts. If the welding or AC power load is
not restarted before the end of the time delay, the
idler reduces the engine speed to low idle speed.
• The engine will automatically return to high idle
speed when there is welding load or AC power
load reapplied.
7. 14-PIN CONNECTOR: For attaching wire
feeder control cables to the RANGER 305D. Includes
contactor closure circuit, auto-sensing remote control
circuit, and 120V and 42V power. The remote control
circuit operates the same as the 6 Pin Amphenol.
8. 6-PIN CONNECTOR: For attaching optional
remote control equipment. Includes auto-sensing
remote control circuit.
9. WELD TERMINALS CONTROL SWITCH: In
the WELD TERMINALS ON position, the output is
electrically hot all the time. In the REMOTELY CON-
TROLLED position, the output is controlled by a wire
feeder or amptrol device, and is electrically off until a
remote switch is depressed.

OPERATION
8. The engine will run at high idle speed for approxi-
mately 12 seconds and then drop to low idle speed.
Allow the engine to warm up at low idle for several

15. ENGINE ALTERNATOR TROUBLE
LIGHT-The engine alternator light is off when battery
charging system is functioning normally. If light turns
on, the alternator or the voltage regulator may not be
operating correctly. The light may also come on due
to the battery not holding a charge. It is normal for the
light to be on while initially starting the engine.
NOTE: If the unit fails to start repeat step 4 through
step 7 after waiting 30 seconds
16. ENGINE HOUR METER – Displays the total
time that the engine has been running. This meter is
useful for scheduling prescribed maintenance.
CAUTION
• Do not allow the starter motor to run continuously
for more than 20 seconds.
17. ENGINE PROTECTION LIGHT-A warning
indicator light for Low Oil Pressure and/or Coolant
Over Temperature. The light is off when the systems
are functioning properly. The light turns on when the
RUN-STOP switch is in the “ON” position prior to
starting the engine. If the Engine Protection or Battery
Charging Lights do “not” turn off shortly after starting
the engine shut off the engine immediately and deter-
mine the cause.
• Do not push the START button while the engine
is running because this can damage the ring
gear and/or the starter motor.
• IF the Engine Protection or Battery Charging
Lights do “not” turn off shortly after starting the
engine shut off the engine immediately and deter
mine the cause.
-----------------------------------------------------------------------
NOTE: When starting a RANGER 305D for the first
time, or after and extended period of time of not oper-
ating, it will take longer than normal because the fuel
pump has to fill the fuel system.

OPERATION
The OUTPUT CONTROL dial adjusts the full output range
for stick welding. The ARC CONTROL dial sets the short
circuit current (arc-force) during stick welding to adjust for
a soft or a more forceful digging arc(crisp). Increasing the
number from –10 (soft) to +10 (crisp) increases the short
circuit current which results in a more forceful digging arc.
Typically a forceful digging arc is preferred for root and hot
passes. A softer arc is preferred for fill and cap passes
where weld puddle control and deposition ("stacking" of
iron) are key to fast travel speeds. It is recommended that
the ARC CONTROL be set initially at 0.
WELDER OPERATION
DUTY CYCLE
Duty Cycle is the percentage of time the load is being
applied in a 10 minute period. For example a 60% duty
cycle, represents 6 minutes of load and 4 minutes of no
load in a 10 minute period.
The Ranger 305D can be used with a broad range of DC
stick electrodes. The MODE switch provides two stick weld-
ing settings as follows:
TIG WELDING
CONSTANT CURRENT (CC-STICK) Welding
The CC-STICK position of the MODE switch is designed for
horizontal and vertical-up welding with all types of elec-
trodes, especially low hydrogen.
The TOUCH START TIG setting of the MODE switch is for
DC TIG (Tungsten Inert Gas) welding. To initiate a weld,
the OUTPUT CONTROL dial is first set to the desired cur-
rent and the tungsten is touched to the work. During the
time the tungsten is touching the work there is very little
voltage or current and, in general, no tungsten contamina-
tion. Then, the tungsten is gently lifted off the work in a
rocking motion, which establishes the arc.
The OUTPUT CONTROL dial adjusts the full output range
for stick welding.
The ARC CONTROL dial sets the short circuit current (arc-
force) during stick welding to adjust for a soft or crisp arc.
Increasing the dial from –10 (soft) to +10 (crisp) increases
the short circuit current and prevents sticking of the elec-
trode to the plate while welding. This can also increase
spatter. It is recommended that the ARC CONTROL be set
to the minimum number without electrode sticking. Start
with a setting at 0.
To stop the arc, simply lift the TIG torch away from the
work piece. When the arc voltage reaches approximately
30 volts, the arc will go out and the machine will automati-
cally reset to the touch start current level. The tungsten
may then be retouched to the work piece to restrike the
arc. The arc may also be started and stopped with an
Amptrol or Arc Start Switch. See the following para-
graphs.
DOWNHILL PIPE (STICK) Welding
The DOWNHILL PIPE position of the MODE switch is a
slope controlled setting intended for "out-of-position" and
"down hill" pipe welding where the operator would like to
control the current level by changing the arc length.

WIRE WELDING-CV
Connect a wire feeder to the Ranger 305D according to
the instructions in INSTALLATION INSTRUCTIONS
Section.
The Ranger 305D in the CV-WIRE mode, permits it to
be used with a broad range of flux cored wire
(Innershield and Outershield) electrodes and solid wires
for MIG welding (gas metal arc welding). Welding can
be finely tuned using the ARC CONTROL. Turning the
ARC CONTROL clockwise from –10 (soft) to +10 (crisp)
changes the arc from soft and washed-in to crisp and
narrow. It acts as an inductance/pinch control. The
proper setting depends on the procedure and operator
preference. Start with the dial set at 0.

OPERATION
AUXILIARY POWER:
NOTE: The 240 V receptacle has two circuits, each of
which measure 120 V to neutral but are of opposite
polarities and cannot be paralleled.
Start the engine and set the IDLER control switch to
the desired operating mode. Full power is available
regardless of the welding control settings providing no
welding current is being drawn.
Simultaneous Welding and Auxiliary Power Loads
The above auxiliary power ratings are with no welding
load. Simultaneous welding and power loads are
specified in the following table. The permissible cur-
rents shown assume that current is being drawn from
either the 120 VAC or 240 VAC supply (not both at the
same time).
The auxiliary power of the RANGER 305D consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles and
one 50 Amp 120/240 VAC (14-50R) receptacle. The
240 VAC receptacle can be split for single phase 120
VAC operation.
The auxiliary power capacity is 10,000 watts Peak,
9500 Watts continuous of 60 Hz, single phase power.
The auxiliary power capacity rating in watts is equiva-
lent to volt-amperes at unity power factor. The max
permissible current of the 240 VAC output is 44 Amps.
The 240 VAC output can be split to provide two sepa-
rate 120 VAC outputs with a max permissible current
of 44 Amps per output to two separate 120 VAC
branch circuits (these circuits cannot be paralleled).
Output voltage is within 10% at all loads up to rated
capacity.
The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.

Engine Oil Change
Drain the engine oil while the engine is warm to
assure rapid and complete draining.
• Remove the oil filter with an oil filter wrench and
drain the oil into a suitable container. Discard the
used filter. Note: Care should be taken during filter
removal to not disrupt or damage in any way the fuel
lines.
• Be sure the unit is off. Disconnect the negative bat-
tery cable to ensure safety.
• Locate oil drain hose and valve in bottom of base
and pull through the hole in the battery access panel
on the welder.
• Clean the filter mounting base and coat the gasket
of the new filter with clean engine oil.
• Screw the new filter on by hand until the gasket con-
tacts the mounting base. Using an oil filter wrench,
tighten the filter an additional 1/2 to 7/8 of a turn.
• Refill the crankcase with the specified amount of the
recommended engine oil. Reinstall the oil filler cap
and tighten securely.
• Remove the cap from the drain valve. Push valve in
and twist counterclockwise. Pull to open and drain
the oil into a suitable container for disposal.
• Close the drain valve by pushing in and twisting
clockwise. Replace the cap.
• Start the engine and check for oil filter leaks.
• Re-fill the crankcase to the upper limit mark on the
dipstick with the recommended oil (see engine oper-
ation manual OR engine service items decal OR
below). Replace and tighten the oil filler cap secure-
ly.
• Stop the engine and check the oil level. If neces-
sary, add oil to the upper limit mark on the dipstick.
WARNING
• Push oil drain hose and valve back into unit, re-con-
nect negative battery cable, and close doors and
engine top cover before restarting unit.Wash your
hands with soap and water after handling used
motor oil. Please dispose of used motor oil in a
manner that is compatible with the environment.
We suggest you take it in a sealed container to your
local service station or recycling center for reclama-
tion. DO NOT throw it in the trash; pour it on the
ground or down a drain.
• Never use gasoline or low flash point
solvents for cleaning the air cleaner
element. A fire or explosion could
result.
CAUTION
• Never run the engine without the air cleaner.
Rapid engine wear will result from contaminants,
such as dust and dirt being drawn into the
engine.

Service Instructions & Installation Tips
For Engine Air Filter
Donaldson filters with RadialSeal™ Sealing
Technology are self-aligning, self-centering,
and self-sealing. A new filter has a dry
lubricant to aid installation. The critical
sealing area will stretch slightly, adjust
itself and distribute the sealing pressure
evenly. To complete a tight seal, apply
pressure by hand at the outer rim of the
filter, not the flexible center. (Avoid
pushing on the center of the urethane end
cap.) No cover pressure is required to hold
the seal. Again, do NOT use the service
cover to push the filter into place!

FUEL
COOLING SYSTEM
WARNING
At the end of each day’s use, refill the fuel tank to min-
imize moisture condensation and dirt contamination in
the fuel line. Do not overfill; leave room for the fuel to
expand.
HOT COOLANT can burn skin.
• Do not remove cap if radiator is
hot.
Use only fresh, No. 2 grade DIESEL fuel. Do not use
kerosene.
------------------------------------------------------------------------
Check the coolant level by observing the level in the
radiator and recovery bottle. Add 50/50 antifreeze /
water solution if the level is close to or below the
"LOW" mark. do not fill above the "FULL" mark.
Remove radiator cap and add coolant to radiator. Fill
up to the top of the tube in the radiator filler neck
which includes a connecting hose coming from the
thermostat housing.
See the Engine Operator's Manual for instructions on
replacing the fuel filter.
BLEEDING THE FUEL SYSTEM
You may need to bleed air from the fuel system if the
fuel filter or fuel lines have been detached, the fuel
tank has been ran empty or after periods of long stor-
age. It is recommended that the fuel shutoff valve be
closed during periods of non-use.
To drain the coolant, open the petcock at the bottom
of the radiator. Open the radiator cap to allow com-
plete drainage. (Tighten the petcock and refill with a
50/50 antifreeze/water solution.) Use an automotive
grade (low silicate) ethylene glycol antifreeze. The
cooling system capacity is 3.85 quarts (3.6L.).
Squeeze upper and lower radiator hoses while filling
to bleed air from system coolant. Replace and tighten
the radiator cap.
The Kubota D722 engine supplied with this welder is
equipped with an automatic bleeding mechanism that
functions when the electric fuel pump is actuated. It is
generally not necessary to open a vent screw or fuel
line fitting to bleed the fuel system.
WARNING
To avoid personal injury, do not bleed a
hot engine. This could cause fuel to spill
onto a hot exhaust manifold, creating a
danger of fire.
CAUTION
Always premix the antifreeze and clean tap water
before adding to the radiator. It is very important
that a precise 50/50 solution be used with this
engine year round. This gives proper cooling dur-
ing hot weather and freezing protection to -34° F (-
37° C).
------------------------------------------------------------------------
Bleed the fuel system as follows:
1. Fill the fuel tank with fuel.
Cooling solution exceeding 50% ethylene glycol
can result in engine overheating and damage to
the engine. Coolant solution must be premixed
before adding to radiator.
2. Open the fuel shut off valve (vertical position of
handle) on the Fuel Filter.
3. Press and hold the glow plug button for 10 to 20
seconds
------------------------------------------------------------------------
Periodically remove the dirt from the radiator fins.
4. Check to see that fuel is flowing through both fuel
filters
Periodically check the fan belt and radiator hoses.
Replace if signs of deterioration are found.
5. Follow the normal STARTING procedures.
TIGHTENING THE FAN BELT
If the fan belt is loose, the engine can overheat and
the battery lose its charge. Check tightness by press-
ing on the belt midway between the pulleys. It should
deflect about .25 in. under a load of 20 lbs. (9 Kg) (6
mm).

MAINTENANCE
CLEANING THE BATTERY
FUEL FILTER
1. Check the fuel filter and fuel pre-filter for water
accumulation or sediment.
Keep the battery clean by wiping it with a damp cloth
when dirty. If the terminals appear corroded, discon-
nect the battery cables and wash the terminals with an
ammonia solution or a solution of 1/4 pound (0.1113
kg) of baking soda and 1 quart (0.9461) of water. Be
sure the battery vent plugs (if equipped) are tight so
that none of the solution enters the cells.
2. Replace the fuel filter if it is found with excessive
water accumulation or sediment. Empty fuel pre-fil-
ter.
After cleaning, flush the outside of the battery, the bat-
tery compartment, and surrounding areas with clear
water. Coat the battery terminals lightly with petroleum
jelly or a non-conductive grease to retard corrosion.
Keep the battery clean and dry. Moisture accumula-
tion on the battery can lead to more rapid discharge
and early battery failure.
OVERSPEED IS HAZARDOUS
The maximum allowable high idle speed for this
machine is 3650 RPM, no load. Do NOT tamper
with governor components or setting or make any
other adjustments to increase the maximum
speed. Severe personal injury and damage to the
machine can result if operated at speeds above
maximum.
CHECKING THE ELECTROLYTE LEVEL
ENGINE ADJUSTMENT
Adjustments to the engine are to be made only by a
Lincoln Service Center or an authorized Field Service
Shop.
If battery cells are low, fill them to the neck of the filler
hole with distilled water and recharge. If one cell is
low, check for leaks.
CHARGING THE BATTERY
BATTERY MAINTENANCE
When you charge, jump, replace, or otherwise con-
nect battery cables to the battery, be sure the polarity
is correct. Improper polarity can damage the charging
circuit. The RANGER 305D positive (+) battery termi-
nal has a red terminal cover.
To access the battery, Disconnect the Negative and
then Positive battery cables. Remove the 2 screws
from the battery door using a screwdriver or a 3/8"
socket. Remove the 2 nuts from the battery bracket
using a 7/16” wrench or socket. Slide the battery out
and remove from welder
If you need to charge the battery with an external
charger, disconnect the negative cable first, then the
positive cable before you attach the charger leads.
After the battery is charged, reconnect the positive
battery cable first and the negative cable last. Failure
to do so can result in damage to the internal charger
components.
WARNING
GASES FROM BATTERY can explode.
● Keep sparks, flame and cigarettes
away from battery.
Follow the instructions of the battery charger manu-
facturer for proper charger settings and charging time.
To prevent EXPLOSION when:
● INSTALLING A NEW BATTERY — disconnect
negative cable from old battery first and con-
nect to new battery last.
SERVICING OPTIONAL SPARK
ARRESTOR
● CONNECTING A BATTERY CHARGER —
