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:  
FUMES AND GASES  
can be dangerous.  
5.a. Welding may produce fumes and gases  
hazardous to health. Avoid breathing these

• DC Manual (Stick) Welder.  
fumes and gases. When welding, keep  
your head out of the fume. Use enough  
• AC Welder with Reduced Voltage Control.  
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. The operation of welding fume control equipment is affected  
by various factors including proper use and positioning of  
the equipment, maintenance of the equipment and the spe-  
cific welding procedure and application involved. Worker  
exposure level should be checked upon installation and  
periodically thereafter to be certain it is within applicable  
OSHA PEL and ACGIH TLV limits.  
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.  
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.c. 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 prod-  
ucts.  
3.i. When working above floor level, use a safety belt to protect  
yourself from a fall should you get a shock.  
5.d. 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.j. Also see Items 6.c. and 8.  
5.e. Read and understand the manufacturerʼs instructions for this  
equipment and the consumables to be used, including the  
material safety data sheet (MSDS) and follow your  
employerʼs safety practices. MSDS forms are available from  
your welding distributor or from the manufacturer.

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 manufacturerʼs  
recommendations.  
6.h. Also see item 1.c.

SAFETY  
5. Toujours porter des lunettes de sécurité dans la zone de  
soudage. Utiliser des lunettes avec écrans lateraux dans les  
zones où lʼon pique le laitier.  
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 dʼincendie 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 dʼincendie.  
Sûreté Pour Soudage A LʼArc  
1. Protegez-vous contre la secousse électrique:  
a. Les circuits à lʼélectrode 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 sʼisoler 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 lʼeau 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 sʼapplicuent aussi au pistolet de  
soudage.  
8. Sʼassurer que la masse est connectée le plus prés possible  
de la zone de travail quʼil est pratique de le faire. Si on place  
la masse sur la charpente de la construction ou dʼautres  
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 dʼincendie ou dʼechauffement des chaines et des  
câbles jusquʼà ce quʼils se rompent.  
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  
dʼopérations de dégraissage, nettoyage ou pistolage. La  
chaleur ou les rayons de lʼarc 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.  
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 nʼimporte quelle partie  
du corps.  
PRÉCAUTIONS DE SÛRETÉ POUR  
LES MACHINES À SOUDER À  
TRANSFORMATEUR ET À  
REDRESSEUR  
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel,  
donc:  
a. Utiliser un bon masque avec un verre filtrant approprié  
ainsi quʼun verre blanc afin de se protéger les yeux du ray-  
onnement de lʼarc et des projections quand on soude ou  
quand on regarde lʼarc.  
b. Porter des vêtements convenables afin de protéger la  
peau de soudeur et des aides contre le rayonnement de  
lʻarc.  
c. Protéger lʼautre personnel travaillant à proximité au  
soudage à lʼaide dʼécrans appropriés et non-inflammables.  
1. Relier à la terre le chassis du poste conformement au code de  
lʼélectricité 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, Iʼinstallation et lʼentretien du poste seront  
effectués par un électricien qualifié.  
4. Des gouttes de laitier en fusion sont émises de lʼarc de  
soudage. Se protéger avec des vêtements de protection libres  
de lʼhuile, tels que les gants en cuir, chemise épaisse, pan-  
talons sans revers, et chaussures montantes.  
3. Avant de faires des travaux à lʼinterieur de poste, la debranch-  
er à lʼinterrupteur à la boite de fusibles.  
4. Garder tous les couvercles et dispositifs de sûreté à leur  
place.

SELECT SUITABLE LOCATION  
An undercarriage, provided on the Ready-Pak w/Cart  
model, is also available to easily move the the unit.  
Refer to the Accessories section of this manual.  
Do not attempt to lift the power source with an  
undercarriage attached.  
Place the welder where clean cooling air can freely  
circulate in and out through the rear louvers. Dirt, dust  
or any foreign material that can be drawn into the  
welder should be kept at a minimum. Failure to  
observe these precautions can result in excessive  
operating temperatures and nuisance shut-downs.  
The undercarriage is designed for hand moving only;  
mechanized movement can lead to personal injury  
and/or damage to the PRECISION TIG 185.  
GRINDING  
TILTING  
Do not direct grinding particles towards the welder. An  
abundance of conductive material can cause mainte-  
nance problems.  
Each machine must be placed on a secure, level sur-  
face, either directly or on a recommended undercar-  
riage. The machine may topple over if this procedure  
is not followed.  
STACKING  
ENVIRONMENTAL RATING  
PRECISION TIG 185 cannot be stacked.  
LIFTING AND MOVING  
The PRECISION TIG 185 power source carries an  
IP21 environmental rating. It may be used in normal  
industrial and commercial environments. Avoid using  
it in environments which have falling water such as  
rain.  
The PRECISION TIG 185 models are provided with

MACHINE GROUNDING AND HIGH FRE-  
QUENCY INTERFERENCE PROTECTION  
This welder must be grounded! See your local and  
national electrical codes for proper grounding  
methods.

INSTALLATION  
6. Keep cover and all screws securely in place.  
The high frequency generator, being similar to a radio  
transmitter, may cause radio, TV and electronic equip-  
ment interference problems. These problems may be  
the result of radiated interference. Proper grounding  
methods can reduce or eliminate radiated interfer-  
ence.  
7. Electrical conductors within 50 ft (15.2m) of the  
welder should be enclosed in grounded rigid metal-  
lic conduit or equivalent shielding, wherever possi-  
ble. Flexible metallic conduit is generally not suit-  
able.  
Radiated interference can develop in the following  
four ways:  
8. When the welder is enclosed in a metal building,the  
metal building should be connected to several good  
earth driven electrical grounds (as in 5 (b) above)  
around the periphery of the building.  
1. Direct interference radiated from the welder.  
2. Direct interference radiated from the welding leads.  
3. Direct interference radiated from feedback into the  
power lines.  
Failure to observe these recommended installation  
procedures can cause radio or TV and electronic  
equipment interference problems and result in unsat-  
isfactory welding performance resulting from lost high  
frequency power.  
4. Interference from re-radiation of “pickup” by  
ungrounded metallic objects.  
Keeping these contributing factors in mind, installing  
equipment per the following instructions should mini-  
mize problems.  
INPUT CONNECTIONS  
1. Keep the welder power supply lines as short as  
possible. Input leads within 50 feet (15.2m) of the  
welder should be enclosed in rigid metallic conduit  
or equivalent shielding. There should be good elec-  
trical contact between this conduit and the welder  
case ground. Both ends of the conduit should be  
connected to a driven ground and the entire length  
should be continuous.  
Be sure the voltage, phase, and frequency of the input  
power is as specified on the rating plate, located on  
the rear of the machine.  
208/230 volt models have a NEMA 6-50P plug  
attached to the #8-3 input power cord and a NEMA 6 -  
50R receptacle is included with the Ready-Pak mod-  
els. Other voltage models have an input power cord  
but no plug or receptacle.  
2. Keep the work and electrode leads as short as pos-  
sible and as close together as possible. Lengths  
should not exceed 25 ft (7.6m). Tape the leads  
together when practical.  
Have a qualified electrician provide input power sup-  
ply to the receptacle or cord in accordance with all  
local and national electrical codes. Use a single phase  
line or one phase of a two or three phase line. Choose  
an input and grounding wire size according to local or  
national codes. Refer to the Technical  
Specifications page at the beginning of this section.  
Fuse the input circuit with the recommended super lag  
3. Be sure the torch and work cable rubber coverings  
are free of cuts and cracks that allow high frequen-  
cy leakage.

4. Keep the torch in good repair and all connections  
tight to reduce high frequency leakage.  
fuses or delay type circuit breakers. Using fuses or  
circuit breakers smaller than recommended may result  
in “nuisance” shut-offs from welder inrush currents  
even if not welding at high currents.  
5. The work piece must be connected to an earth  
ground close to the work clamp, using one of the  
following methods:  
1
Also called “inverse time” or “thermal/magnetic” circuit breakers;  
circuit breakers which have a delay in tripping action that decreases  
as the magnitude of the current increases.  
a) A metal underground water pipe in direct contact  
with the earth for ten feet or more.  
b) A 3/4” (19mm) galvanized pipe or a 5/8”  
(16mm)solid galvanized iron, steel or copper rod  
driven at least eight feet into the ground.  
The ground should be securely made and the ground-  
ing cable should be as short as possible using cable  
of the same size as the work cable, or larger.  
Grounding to the building frame electrical conduit or  
along pipe system can result in re-radiation, effectively  
making these members radiating antennas.

RECOMMENDED PROCESSES AND  
EQUIPMENT  
RECOMMENDED PROCESSES  
If a PRECISION Tig 185 is powered from an engine  
generator which doesnʼt have sufficient capacity, the  
AC Balance control and the Output control will not  
provide full range of control.  
The PRECISION TIG 185 is recommended for the  
TIG (GTAW) and Stick (SMAW) welding processes  
within its output capacity range of 5 amps DC,or 7  
amps AC, to 185 amps AC/DC. It is compatible with  
most Magnum TIG accessories, as well as many  
industry standard items, such as TIG torches (adapted  
for Twist-Mate), hoses, and water coolers.  
WELDING CAPABILITY(Duty Cycle)  
The PRECISION TIG 185 is rated at 185 amps, 27  
volts, at 15% duty cycle on a ten minute basis. It is  
capable of higher duty cycles at lower output currents.  
See rated output graph, on specification sheet located  
in the Installation Section. If the duty cycle is exceed-  
ed, a thermal protector will shut off the output until the  
machine cools.  
PROCESS LIMITATIONS  
The PRECISION TIG machines are not recommended  
for arc gouging due to it's limited output capacity, and  
are also not recommended for pipe thawing.

CONTROL FUNCTIONALITY  
This setting position feature automatically provides the  
proper amount of cleaning and penetration for normal  
AC TIG welding.  
1. POWER SWITCH – Input line switch turns input  
power ON or OFF, as indicated by the on or off sta-  
tus of the front panel digital display (See Item 6).  
5. MAXIMUM OUTPUT CONTROL – Presets the out-  
put welding current over the rated output range of  
the machine:  
2. POLARITY SWITCH – The rotary power switch has  
3-positions for DC+, AC and DC- selections for the  
electrode output stud welding polarity.  
• With a Remote Current Control (Amptrol) connect-  
ed to the Remote Receptacle (See item 10), this  
knob sets the Maximum output current level set  
table with the remote Amptrol.  
CAUTION  
• Do not switch the polarity switch  
while welding or damage may result  
to the machine.  
• For Pulse TIG (See Item 8) this knob sets the  
Peak Pulse level, with the Remote Amptrol (if  
used).  
------------------------------------------------------------------------  
3. MODE SWITCH – The push button switch allows  
selection of the two machine welding modes as  
indicated by colored mode lights:  
6. DIGITAL METER – A 3 digit LED meter is used to  
display the preset output current level before weld-  
ing, and actual output level while welding:  
• A lit display indicates input power is turned on.  
(See Item 1.)  
• STICK mode – Top position Red light.  
• TIG mode – Bottom position Green light.  
4. AC BALANCE CONTROL – The AC Balance  
Control permits adjustment of the AC TIG wave bal-  
ance adjustment from Max. Penetration (80% nega-  
tive wave) at full CW rotation setting, to Max.

includes:  
7. POST FLOW TIME – Sets the TIG mode shielding  
gas post flow time over the range of about 1 to 30  
seconds after the arc is shut off.  
Note: Gas preflow time is fixed at 0.5 second only in  
TIG mode, but no preflow time will occur if the arc is  
restarted during Post Flow time, since shielding gas  
would not have stopped flowing.  
• Auto Balance position indicated by the Green panel  
light turning on.

OPERATION  
8. PULSE TIG CONTROL – The Pulse TIG feature  
built into the Precision TIG 185 is simplified to be a  
single knob control which sets the Pulse Frequency  
over the peak pulses/sec. range of about 0.1 to 20  
pulses per second:  
OPERATING STEPS  
WELDING IN TIG MODE  
1. Connect the TIG torch and cable Twist-Mate quick  
connect plug to the Electrode/Gas output recepta-  
cle. This receptacle also contains an integral gas  
connection for the torch. Connect the work clamp to  
the work piece.  
• Full CCW (min.) setting of the control knob shuts  
off Pulse TIG (0.0 pps).  
• Peak Pulse level is set by the Max. Output Control  
and the Remote Amptrol (if used).  
• Background Current level is typically optimized at  
a fixed 50% of Peak Pulse level setting.  
• Peak Pulse % On-time is typically optimized at a  
fixed50%.  
2. Set the TIG/STICK switch to “TIG”.  
3. Set the Polarity Switch to DC- for welding steel or  
stainless steel; or to AC for welding aluminum.  
A Green light "blinks" with each Peak Pulse to indi-  
cate the Pulse TIG Control setting before and dur-  
ing welding.  
4. Connect the Foot Amptrol to the Remote Control  
Connector.  
9. OVER TEMPERATURE LIGHT - If the welder  
overheats due to blocked air flow, high ambient air  
temperature, or exceeded duty cycle, an internal  
thermostat will open disabling the welding output  
and this yellow light will illuminate. The cooling fans  
will continue to run to cool the unit during this time.  
The light will go out when the unit cools and the  
thermostat resets. Once the light goes out, the  
machine will again become available to weld.  
5. Turn on the cylinder gas valve and adjust the flow  
regulator to obtain desired flow.  
6. Turn the power switch to “ON”. NOTE: There will be  
a 15 second gas flow when the power is turned on.  
7. Preset the Output Control on the control panel to  
the maximum desired amps, as read on the digital  
meter.  
10. REMOTE RECEPTACLE – Provides for connec-  
tion of remote control and/or arc start switch only  
in TIG Mode: ( There is no remote output control  
capability when stick welding.  
8. Depress the Foot Amptrol to energize the torch and  
establish an an arc with the work piece. The digital  
meter reads the actual amps while welding.  
• Plugging a remote current control (Amptrol) into  
this receptacle automatically switches the output  
control from the panel Max Output Control (See  
Item 5) to the remote control.  
NOTE: When the TIG/STICK switch is set to “TIG”,  
depressing the remote control will start a 0.5 second  
gas pre-flow before energizing the TIG torch. When  
the remote control is released the TIG torch is de-  
energized and gas flow will continue for the time set  
by the Post Flow Time control. When the polarity  
switch is set to DC, the TIG Arc Starter will turn on  
and off automatically to start and stabilize the arc. In  
AC the TIG Arc Starter will turn on with the output and  
remain on continuously until the remote control is  
released.  
• The connected remote control will then control  
the output current between the Min. range of the  
machine and the setting of the panel Max Output  
Control.  
• Switching Mode Switch (See Item 3) to Stick will  
automatically disable the connected remote con-  
trol and switch the output control back to the Max  
Output panel control.  
PULSE TIG CONTROL  
11. ELECTRODE/GAS OUTPUT RECEPTACLE -  
This quick connect Twist-Mate receptacle provides  
electrical connection to the electrode holder and  
cable for Stick welding and a combined electrical  
and gas connection for the TIG torch when TIG  
welding.  
12. WORK CABLE - This work cable is factory con-  
nected to the welder and is connected to the work  
piece to complete the welding circuit. Refer to  
Machine Grounding and High Frequency  
Interference Protection in the Installation section  
of this manual for the proper procedure on ground-  
ing the work clamp and work piece to minimize  
high frequency interference.  
Use this knob to set the frequency or the number of  
pulses per second(pps), from 0.1pps to 20pps.  
• This setting adjusts heat output and bead shape for  
travel speed. Thinner plate that is welded with faster  
travel speed will require higher frequency than thick-  
er plate with slower travel speed. 2-3pps is a typical  
starting point.

OPERATION  
REMOTE CONTROL OPERATION  
BENEFITS OF THE PRECISION TIG 185 DESIGN  
A Foot Amptrol ™is included with the PRECISION  
TIG 185 Ready-Pak models and availiable for other  
models (See Accessories Section) for remote current  
control while TIG welding. An optional Hand Amptrol  
may also be used. An optional Arc Start Switch may  
be used to start and stop the welding if no remote  
control of the current is desired. Refer to the  
Accessories Section of this manual.  
In AC TIG welding of aluminum, the positive portion of  
the AC wave provides cleaning (removal of aluminum  
oxide) of the work piece. This is desirable on materials  
with a heavy oxide coating. However the positive por-  
tion may also cause the electrode to overheat at high  
currents causing “tungsten spitting”. The negative por-  
tion of the AC wave offers no cleaning action but con-  
centrates more heat on the work.  
Both the Hand and Foot Amptrol work in a similar  
manner. For simplicity, the following explanation will  
refer only to “Amptrols”, meaning both Foot and Hand  
models. The term “minimum” refers to a foot pedal in  
the “up” position, as it would be with no foot pressure,  
or a Hand Amptrol in the relaxed position, with no  
thumb pressure.  
The AC waveform of the PRECISION TIG 185 opti-  
mizes cleaning and heating of the work. The result is  
the capability to weld through the complete range in  
AC TIG or DC- TIG requiring only one electrode, a  
3/32” 2% thoriated tungsten.  
“Maximum” refers to a fully depressed Foot Amptrol,or  
a fully extended Hand Amptrol.  
When the welder is in TIG modes activating the  
Amptrol energizes the electrode terminal and varies  
the output welding current from its minimum value of 5  
Amp (DC) or 7 Amp (AC), to the maximum value set  
by the Current Control on the control panel. This helps  
eliminate accidental high current damage to the work  
piece and/or tungsten, and provides a fine control of  
the current. When the welder is in the stick mode a  
remote control has no effect and is not used.  
It is important to note that, in some cases, the tung-  
sten will not start an arc at the minimum current  
because the tungsten may be too large or cold. To  
start an arc reliably, it is important to depress the  
Amptrol far enough so that the machine output current  
is near the tungsten operating range. For example, a  
3/32” tungsten may be used on DC- to weld over the  
full range of the machine.  
To start the arc, the operator may have to turn the cur-  
rent control up and depress the Amptrol approximately  
1/4 of the way down. Depressing the Amptrol to its  
minimum position may not start the arc. Also if the  
current control is set too low, the arc may not start. In  
most cases, a large or cold tungsten will not readily  
establish an arc at low currents. This is normal. In  
Direct Current mode the PRECISION TIG 185 will  
start a 3/32”, 2% thoriated tungsten electrode at 15  
amperes provided the electrode tip is properly ground-  
ed and not contaminated.

MAINTENANCE  
SAFETY PRECAUTIONS  
WARNING  
Use extreme caution when working with circuit of  
the high frequency. The high voltages developed  
can be lethal. Turn the input power off using the  
disconnect switch or fuse box before working  
inside machine. This is particularly important  
when working on the secondary circuit of the high  
voltage transformer (T3) because the output volt-  
age is dangerously high.  
WARNING  
ELECTRIC SHOCK can kill.  
• Only qualified personnel should per-  
form this maintenance.  
• Turn the input power OFF at the dis-  
connect switch or fuse box before  
working on this equipment.  
-----------------------------------------------------------------------  
Refer to figure D.1. Note in highly dirty environments  
where there is an abundance of conductive contami-  
nants, use a low pressure air stream or a firm piece of  
paper to clean the spark gap. Do not disturb the facto-  
ry setting.  
• Do not touch electrically hot parts.  
------------------------------------------------------------------------  
WARNING  
To check the spark gap:  
- Turn off input power as specified above.  
- Remove the right side panel from the  
machine, the spark gap box is located on the  
lower right side.  
To avoid receiving a high frequency shock, keep  
the TIG torch and cables in good condition.  
------------------------------------------------------------------------  
- Check the spark gap with a feeler gauge.  
If adjustment is needed:  
ROUTINE AND PERIODIC MAINTENANCE  
- Adjust the gap by loosening the allen head  
screw in one of the aluminum blocks, near  
the front of the unit and tighten the screw in  
the new position.  
1. Disconnect power supply lines to machine before  
performing periodic maintenance.  
If the gap is correct:  
2. Periodically clean the inside of the machine with a  
low pressure air system. Be sure to clean the fol-  
lowing components thoroughly.  
• Main Transformer  
- Replace the wraparound.  
8. Inspect gas hose and inlet fitting for cracks or leaks.  
9. Replace any unreadable labels or decals.  
• Electrode/Gas Output Receptacle  
• Polarity Switch  
• Rectifier Assembly  
10. Verify that the machine and welding circuit is prop-  
erly grounded.  
• Arc Starter/Spark Gap Assembly  
• PC Boards  
FIGURE D.1 SPARK GAP  
• Fan Blades  
3. Inspect welder output and control cables for fraying,  
cuts, and bare spots.  
.020 Spark Gap  
4. Keep TIG torch and cables in good condition.  
5. Clean air louvers to ensure proper air flow and cool-  
ing.  
FAN MOTOR OR FAN BLADE REPLACEMENT  
When installing a new fan blade or fan motor be sure  
to maintain proper shaft spacing per Figure D.2 below.  
6. The fan motor has sealed ball bearings which  
require no maintenance.  
7. SPARK GAP ADJUSTMENT  
The spark gap .020(.5mm) is set at the factory to a  
gap of 0.015 inches (0.4mm) See Figure D.1. This  
setting is adequate for most applications. Where  
less high frequency is desired, the setting can be  
reduced to 0.015 inches (0.4mm).
