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:

FUMES AND GASES

can be dangerous.

5.a. Welding may produce fumes and gases

hazardous to health. Avoid breathing these

• Semiautomatic DC Constant Voltage (Wire) Welder.

• DC Manual (Stick) Welder.

• AC Welder with Reduced Voltage Control.

fumes and gases.When welding, keep

your head out of the fume. Use enough

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

products.

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.

8.a. Turn off input power using the disconnect

switch at the fuse box before working on

the 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.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.

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.

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.

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.

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.

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.

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.

b. Porter des vêtements convenables afin de protéger la

peau de soudeur et des aides contre le rayonnement de

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.

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

SAFETY PRECAUTIONS

WARNING

STORING

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.

1. Store the machine in a cool, dry place when it is

not in use. Protect it from dust and dirt. Keep it

where it can’t be accidentally damaged from con-

struction activities, moving vehicles, and other

hazards.

------------------------------------------------------------------------

ELECTRIC SHOCK can kill.

2. Drain the engine oil and refill with fresh oil. Run

the engine for about five minutes to circulate oil to

all the parts. See the MAINTENANCE section of

this manual for details on changing oil.

• Do not touch electrically live parts or

electrode with skin or wet clothing.

• Insulate yourself from work and

ground

• Always wear dry insulating gloves.

------------------------------------------------------------------------

ENGINE EXHAUST can kill.

3. Remove the battery, recharge it, and adjust the

electrolyte level. Store the battery in a dry, dark

place.

• Use in open, well ventilated areas or

vent exhaust outside.

------------------------------------------------------------------------

MOVING PARTS can injure.

STACKING

• Do not operate with doors open or

guards off.

GX-271 machines CANNOT be stacked.

• Stop engine before servicing.

• Keep away from moving parts.

------------------------------------------------------------------------

ANGLE OF OPERATION

See additional warning information at

front of this operator’s manual.

-----------------------------------------------------------

Place the machine on a secure, level surface whenev-

er you use it or store it. Any surfaces you place it on

other than the ground must be firm, non-skid, and

structurally sound.

Only qualified personnel should install,

use, or service this equipment.

The engine is designed to run in a level position for

best performance. It can operate at an angle, but this

should never be more than 15 degrees in any direc-

tion. If you do operate it at a slight angle, be sure to

check the oil regularly and keep the oil level at the

FULL mark as it would be in its normal level condition.

Also, fuel capacity will be a little less at an angle.

LOCATION AND VENTILATION

Whenever you use the GX-271, be sure that clean

cooling air can flow through the machine’s engine and

the machine case. Avoid dusty, dirty areas. Also,

keep the machine away from heat sources. Do not

place the engine end of the machine anywhere near

hot engine exhaust from another machine or closer

than two feet from a wall. And of course, make sure

that engine exhaust is ventilated to an open, outside

area.

The GX-271 may be used outdoors. Do not set the

machine in puddles or otherwise submerge it in water.

Such practices pose safety hazards and cause

improper operation and corrosion of parts.

INSTALLATION

HIGH ALTITUDE OPERATION

PRE-OPERATION ENGINE SERVICE

At high altitude, the standard carburetor air-fuel mix-

ture will be too rich. Performance will decrease, and

fuel consumption will increase. A very rich mixture will

also foul the spark plug and cause hard starting.

CAUTION

READ and UNDERSTAND the engine operating and

maintenance instructions supplied with this machine.

------------------------------------------------------------------------

High altitude performance can be improved by specific

modifications to the carburetor. If you always operate

your engine at altitudes above (6,000 feet) 1,800

meters, have a engine dealer perform this carburetor

modification.

WARNING

• Keep hands way from the engine muffler or HOT

engine parts.

Even with carburetor modification, engine horsepower

will decrease about 3.5% for each 1,000 feet (300

meter) increase in altitude. The effect of altitude on

horsepower will be greater than this if no carburetor

modification is made. Do not operate a modified

engine below 6,000 feet.

• Stop the engine when fueling.

• Do not smoke when fueling.

• Do not overfill the fuel tank.

• Wipe up spilled fuel and allow the fumes to clear

before starting the engine.

LIFTING

• Keep sparks and flame away from the fuel tank.

The GX-271 weighs approximately 469 lbs/212 kg. A

lift bail is mounted to the machine frame and should

always be used when lifting the machine.

------------------------------------------------------------------------

OIL

ADDITIONAL SAFETY PRECAUTIONS

The GX-271 is shipped with the engine filled with SAE

10W-30 oil. CHECK THE OIL LEVEL BEFORE YOU

START THE ENGINE. If it is not full, add enough oil

to fill it to the full mark.

WARNING

FALLING EQUIPMENT can cause

injury.

● Do not lift this machine using lift

bale if it is equipped with a heavy

accessory such as trailer or gas

cylinder.

For more information on oil viscosity and service con-

ditions, see the MAINTENANCE section of this manu-

al and the engine Operator’s Manual.

CABLE INSTALLATION

WARNING

Install the welding cables to your GX-271 as follows.

See Figure B.1 for location of parts.

Do not ground the machine to a pipe that carries

explosive or combustible material.

------------------------------------------------------------------------

1. The engine must be OFF to install welding cables.

2. Remove the flanged nuts from the output terminals.

When the GX-271 is mounted on a truck or a trailer,

the machine generator ground stud MUST be securely

connected to the metal frame of the vehicle. See

Figure B.1. The ground stud is marked with the

ground symbol.

3. Connect the electrode holder and work cables to

the weld “+” and “-” output terminals. The terminals

are identified on the case front. The polarity require-

ment for the welding process being used deter-

mines which terminal the electrode cable is

attached to.

If the GX-271 is connected to premises wiring such as

a home or shop, it must be properly connected to the

system earth ground.

4. Tighten the flanged nuts securely.

WELDING CABLE CONNECTIONS

5. Be certain that the metal piece you are welding (the

“work”) is properly connected to the work clamp and

cable.

CABLE SIZE AND LENGTH

Be sure to use welding cables that are large enough.

The correct size and length becomes especially

important when you are welding at a distance from the

welder.

6. Check and tighten the connections periodically.

CAUTION

• Loose connections will cause the output terminals to

overheat. The terminals may eventually melt.

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.

• Do not cross the welding cables at the output termi-

nal connection. Keep the cables isolated and sepa-

rate from one another.

INSTALLATION

AUXILIARY POWER RECEPTACLES,

PLUGS, AND HAND-HELD EQUIPMENT

PREMISES WIRING

The GX-271 is suitable for temporary, standby, or

emergency power using the engine manufacturer’s

recommended maintenance schedule. With its three-

wire grounded neutral generator, it can be permanent-

ly installed as a standby power unit for 240 volt, three

wire, single phase 33 ampere service.

The control panel of the GX-271 features three auxil-

iary power receptacles: See Figure B.1.

• Two 15 amp, 120 volt duplex (double outlet) recepta-

cles.

• One 50 amp 120/240 volt single outlet receptacle.

WARNING

Only a licensed, certified, trained electrician should

install the machine to a premises or residential elec-

trical system. Be certain that:

Through these receptacles the machine can supply up

to 8,000 rated continuous watts of single-phase, 60

Hz AC power.

• The installation complies with the National Electrical

Code and all other applicable electrical codes.

For further protection against electric shock, any elec-

trical equipment connected to the 120V duplex recep-

tacles must use a three-blade, grounded type plug or

an Underwriter’s Laboratories (UL) approved double

insulation system with a two-blade plug. Lincoln

offers an accessory plug kit that has the right type of

plugs. See the ACCESSORIES section of this manual

for more information.

• The premises is isolated and no feedbacking into

the utility system can occur. Certain state and local

laws require the premises to be isolated before the

generator is linked to the premises. Check your

state and local requirements.

• A double pole, double throw transfer switch in con-

junction with the properly rated double throw circuit

breaker is connected between the generator power

and the utility meter.

------------------------------------------------------------------------

The following information and the connection diagram,

Figure A.1, can be used as a guide by the electrician

for most applications to premises wiring.

If you need ground fault protection for hand-held

equipment refer to the K896-1 GFCI Receptacle kit in

the ACCESSORIES section of this manual for more

information.

For recommended extension cord lengths and sizes

see Table A.1.

1. Install a double pole, double throw switch between

the power company meter and the premises dis-

connect. The switch rating must be the same as

or greater than the premises disconnect and

service overcurrent protection.

CIRCUIT BREAKERS

The GX-271 machines are equipped with 50 amp cir-

cuit breakers on the 120/240 V receptacle and 15 amp

circuit breakers on the 120 receptacles for overload

protection. Under high heat a breaker may tend to trip

at lower loads than it would normally.

2. Take the necessary steps to assure that the load is

limited to the capacity of the GX-271 by installing a

35 amp 240 volt double pole circuit breaker.

Maximum rated load for the 240 volt auxiliary is 33

amperes. Loading above 33 amperes will reduce

output voltage below the allowable -10% of rated

voltage. This may damage appliances or other

motor-driven equipment.

CAUTION

Never bypass the circuit breakers. Without overload

protection, the GX-271 could overheat and/or cause

damage to the equipment being used.

------------------------------------------------------------------------

3. Install a 50 amp 120/240 volt plug (NEMA type 14-

50) to a double pole circuit breaker using No. 8 or

larger, 4 conductor cable of the desired length.

(The 50 amp 120/240 volt plug is available in the

optional power plug kit.

4. Plug this cable in to the 50 amp 120/240 volt recep-

tacle on the GX-271 case front.

mode.

WELDING OPERATION

WARNING

“STICK/TIG” mode: In this mode, the “ARC CON-

TROL” knob sets the short circuit (arc force) current

during stick welding. Increasing the number from 1 to

10 increases the short circuit current. This prevents

sticking of the electrode to the plate at low welding

current settings. This also increases spatter. It is rec-

ommended that the control is set to the minimum

number without electrode sticking.

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.

------------------------------------------------------------------------

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or

electrode with skin or wet clothing.

• Insulate yourself from work and

ground

“WIRE WELDING” mode: In this mode, increasing

the number from 1 to 10 changes the arc from soft

and washed in to crisp and narrow. It acts as an

inductance control. The proper setting depends on

the application and operator preference. In general,

Mig welding performs best in the “SOFT” range and

Innershield in the “CRISP” range.

• Always wear dry insulating gloves.

------------------------------------------------------------------------

FUMES AND GASES can be dangerous.

• Keep your head out of fumes.

• Use ventilation or exhaust to remove

fumes from breathing zone.

------------------------------------------------------------------------

MOVING PARTS can injure.

See additional warning information

throughout this operator’s manual.

-----------------------------------------------------------

The toggle switch on the control panel labeled

“WELDING TERMINALS ALWAYS ON” and “WELD-

ING TERMINALS REMOTELY CONTROLLED”, is

used to control the operation of the solid state contac-

tor which allows for the selection of “Hot” or “Cold”

welding terminals.

WELDER CONTROLS - FUNCTION

AND OPERATION

See Figure B.1 for control locations.

With the switch in the “WELDING TERMINALS

ALWAYS ON” position, the contactor is closed and

the welding terminals are always “Hot.”

Output “CONTROL”

Continuous CC welding current control from 20 amps

to 300 amps in the STICK/TIG and PIPE modes.

Continuous CV welding arc voltage control from 11

volts to 32 volts in the WIRE FEED mode.

With the switch in the “WELDING TERMINALS

REMOTELY CONTROLLED” position, the contactor

B-7

OPERATION

When the triggering device is pressed the contactor is

closed and the welding terminals are “Hot.”

TIG WELDING

The GX-271 can be used in a wide variety of DC

Tungsten Inert Gas (TIG) welding applications. When

used with the K930-1 or -2 TIG module, ratings are

limited to 275A at a 60% duty cycle and 250A at a

80% duty cycle.

When the triggering device is released the contactor is

opened and the welding terminals are “Cold.”

“MODE” Switch - Set to the desired process:

STICK/TIG, PIPE, or WIRE FEED.

GX-271 settings when using the K930-1 or -2 Tig

Module:

“WIRE FEEDER VOLTMETER” Switch - If

using a wire feeder that has a voltmeter, set this

switch to match the polarity of the electrode.

a. Set the “MODE” Switch to the STICK/TIG setting.

b. Set the “IDLER” Switch to the “AUTO” position.

STICK WELDING

c. Set the “LOCAL/REMOTE” switch to the

“REMOTE” position.

The GX-271 can be used with a broad range of DC

stick electrodes. The output “CONTROL” adjusts the

full range of 20 to 300 amps. Set the “ARC CON-

TROL” to low setting to minimize spatter. If sticking is

a problem, turn this control to a higher setting (clock-

wise). This will increase the short circuit current (arc

force).

d. Set the ”WELDING TERMINALS” switch to the

“WELDING TERMINALS REMOTELY CON-

TROLLED” position. This will keep the “Solid

State” contactor open and provide a “cold” elec-

trode until the triggering device (Amptrol or Arc

Start Switch) is pressed.

PIPE WELDING

e. Set the “ARC CONTROL” to minimum.

The “PIPE WELDING” mode is recommended for

manual vertical-down techniques on pipe joints using

EXX10 type electrodes. This slope controlled setting

allows the operator to control the welding current by

changing the arc length.

See Table B.2 for Typical Current Ranges for

Tungsten Electrodes.

(5) TIG torch nozzles are typically made from alumina ceramic. Special applications may require lava nozzles, which are

less prone to breakage, but cannot withstand high temperatures and high duty cycles.

Some recommended solid wires for MIG welding are:

.035 (0.9 mm) and .045 (1.1 mm) L-50, L-56, and

Blue Max MIG 308 LS.

WIRE WELDING

Connect a wire feeder to the GX-271 and set welder

controls according to the instructions on the appropri-

ate wire feeder connection diagram.

For any electrodes, including the above recommenda-

tions, the procedures should be kept within the rating

of the machine. For additional electrode information,

see Lincoln publications N-675, GS-100 and GS-210.

The GX-271 in the ”WIRE FEED” position, 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 CON-

TROL”.

Some recommended Innershield electrodes are: NR-

311, NS-3M, NR-207, NR-203 Ni 1%, NR-204-H.

Recommended Outershield electrodes are: 0S-70,

0S-71M.

OPERATION

The 120V duplex auxiliary power receptacles should

only be used with three wire grounded type plugs or

approved double insulated tools with two wire plugs.

AUXILIARY POWER

Start the engine and set the "IDLER" control switch to

the desired operating mode. Full power is available

regardless of the welding output settings, if no welding

current is being drawn.

The current rating of any plug used with the system

must be at least equal to the current capacity of the

associated receptacle.

The auxiliary power of the GX-271 consists of two 15

Amp-120VAC (5-15R) duplex receptacles and one 50

Amp 120/240 VAC (14-50R) receptacle.

NOTE: The 240V receptacle has two circuits, each of

which measure 120 V to neutral but are of opposite

polarities and cannot be paralleled.

The auxiliary power capacity is 8,000 watts of 60 Hz,

single phase power. The auxiliary power capacity rat-

ing in watts is equivalent to volt-amperes at unity

power factor. The max permissible current of the 240

VAC output is 33 Amps. The 240 VAC output can be

split to provide two separate 120 VAC outputs with a

max permissible current of 33 Amps per output to two

separate 120 VAC branch circuits. Output voltage is

within Å 10% at all loads up to rated capacity.

SIMULTANEOUS WELDING AND POWER

LOADS

It must be noted that the above auxiliary power ratings

are with no welding load. Simultaneous welding and

power loads are specified in the following table. The

permissible currents shown assume that current is

being drawn from either the 120 VAC or 240 VAC

supply (not both at the same time).

MAINTENANCE

SAFETY PRECAUTIONS

WARNING

ROUTINE AND PERIODIC ENGINE

MAINTENANCE

Have qualified personnel do the maintenance

work. Turn the engine off before working inside

the machine. In some cases, it may be

necessary to remove safety guards to perform

required maintenance. Remove guards only

when necessary and replace them when the

maintenance requiring their removal is

complete. Always use the greatest care when

working near moving parts.

At the end of each day’s use, refill the fuel tank to min-

imize moisture condensation in the tank. Running out

of fuel tends to draw dirt into the fuel system. Also,

check the crankcase oil level and add oil if indicated.

dust and dirt being drawn into the engine.

------------------------------------------------------------------------

HONDA ENGINE

Wash your hands with soap and water after handling

used 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 sta-

tion or recycling center for reclamation. Do not throw

it in the trash, pour it on the ground or down a drain.

times on a hard surface to remove excess dirt, or

blow compressed (not exceeding 2.1 kg/cm2 (30

psi) air through the filter from the air cleaner cover

side. Never try to brush the dirt off; brushing will

force dirt into the fibers. Replace the paper ele-

ment if it is excessively dirty. Replace the paper

element and both gaskets.

3. Clean the filter mounting base, and coat the gasket

of the new oil filter with clean engine oil.

4. Screw on the new oil filter by hand, until the gasket
