against the fumes produced to reduce the
risk of developing the above illnesses.
2. do not use near degreasing or
painting operations.
3. Keep head out of fumes.
Do not breathe exhaust fumes.
4. Use enough ventilation, exhaust at arc, or
both, to keep fumes and gases from breathing
zone and general area. If engineering controls
are not feasible, use an approved respirator.
5. Work in a confined area only if it
is well-ventilated, or while wearing
an air-supplied respirator.
6. Have a recognized specialist in
Industrial Hygiene or Environmental Services
check the operation and air quality
and make recommendations
for the specific welding situation.
Follow OSHA guidelines for
Permissible Exposure Limits (PEL’s) and
the American Conference of Governmental
Industrial Hygienists recommendations for
Threshold Limit Values (TLV’s) for fumes and gases.
Arc Ray Safety

5. people with pacemakers should consult their
physician(s) before use. Electromagnetic fields
in close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
6. do not expose welders to rain or wet conditions.
Water entering a welder will increase
the risk of electric shock.
7. do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the welder.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled
cords increase the risk of electric shock.
8. do not use outdoors.

ground. Use nonflammable, dry insulating
material if possible, or use dry rubber mats,
dry wood or plywood, or other dry insulating
material large enough to cover your full
area of contact with the work or ground.
Fire Safety
ARc ANd SLAg can cause fire.
1. clear away or protect flammable objects.
Remove or make safe all combustible materials for a
radius of 35 feet (10 meters) around the work area.
Use a fire resistant material to cover
or block all open doorways, windows,
cracks, and other openings.
2. Keep ABc-type fire extinguisher near
work area and know how to use it.
3. Maintain a safe working environment.
Keep the work area well lit.
Make sure there is adequate
surrounding workspace. Keep the work area free
of obstructions, grease, oil, trash, and other debris.
4. do not operate welders in atmospheres
containing dangerously reactive or
flammable liquids, gases, vapors, or dust.
Provide adequate ventilation in work areas
to prevent accumulation of such substances.
Welders create sparks which may ignite flammable
substances or make reactive fumes toxic.
5. If working on a metal wall, ceiling, etc.,
prevent ignition of combustibles on the
other side by moving the combustibles to a
safe location. If relocation of combustibles is
not possible, designate someone to serve as
a fire watch, equipped with a fire extinguisher,
during the cutting process and for at least one
half hour after the cutting is completed.
6. do not weld or cut on materials having
a combustible coating or combustible
internal structure, as in walls or ceilings, without
an approved method for eliminating the hazard.
7. do not dispose of hot slag in containers
holding combustible materials.
8. After welding, make a thorough examination
for evidence of fire. Be aware that easily
visible smoke or flame may not be present
for some time after the fire has started.
9. do not apply heat to a container that has held
an unknown substance or a combustible
material whose contents, when heated,
can produce flammable or explosive vapors.
Clean and purge containers before applying heat.
Vent closed containers, including castings,
before preheating, welding, or cutting.

the same thickness as your intended workpiece to
practice technique before welding anything of value.
1. Clean the weld surfaces thoroughly with a
wire brush or angle grinder; there must be
no corrosion, paint, oil, or other materials
on the weld surfaces, only bare metal.
2. Use clamps (not included) to hold the workpieces
in position so that you can concentrate on
proper welding technique. The distance
(if any) between the two workpieces must be
controlled properly to allow the weld to hold
both sides securely while allowing the weld
to penetrate fully into the joint. The edges of
thicker workpieces may need to be chamfered
(or beveled) to allow proper weld penetration.
NOTICE: When welding equipment on a vehicle,
disconnect the vehicle battery power from both the
positive connection and the ground before welding.
This prevents damage to some vehicle electrical
systems and electronics due to the high voltage
and high frequency bursts common in welding.

Duty Cycle (Duration of Use)
Avoid damage to the Welder by not welding for
more than the prescribed duty cycle time. The Duty
Cycle defines the number of minutes, within a 10 minute
period, during which a given welding process can
produce a particular welding current without overheating.
For example, a 30% duty cycle at 165 A welding
current must be allowed to rest for at least 7 minutes
after every 3 minutes of continuous welding.
Failure to carefully observe duty cycle limitations
can easily over-stress a welder’s power generation
system contributing to premature welder failure.
This welder has an internal thermal protection
system to help prevent this sort of over-stress.
When the Welder overheats, it automatically shuts
down and the Overload Indicator lights. The
welder automatically returns to service after cooling
off. Rest the Tig Torch or Electrode Holder on an
electrically non-conductive, heat-proof surface, such
as a concrete slab, well clear of the ground clamp.
Allow the Welder to cool with the power Switch on,
so that the internal Fan will help cool the welder.
When the Overload Indicator is no longer lit and the
Welder can be used again, use shorter welding periods
and longer rest periods to prevent needless wear.

TIg Welding
TO pREVENT SERIOUS INJURy ANd dEATH:
do not weld without grounding clamp.
When the operator is not holding the Torch, it must be sitting on a nonconductive, nonflammable surface.
Only hold TIg Rod with an electrically insulated welding glove.
TO pREVENT dEATH FROM ASpHyXIATION:
do not open gas without proper ventilation. Fix gas leaks immediately. Shielding gas can displace
air and cause rapid loss of consciousness and death. Shielding gas without carbon dioxide can be
even more hazardous because asphyxiation can start without feeling shortness of breath.
NOTIcE: TIG welding is a complicated process,
requiring experience and skill to achieve
successful results. Training beyond the scope of
this manual is required to TIG weld properly.
1. Open gas cylinder’s valve all the way.
2. Set Flow Gauge to SCFH value indicated
on Settings Chart on top of Welder.
3. Turn the Power Switch to the OFF position, then
plug the Welder into a properly grounded, GFCI
protected, 120 VAC (20 amp rated) outlet or
240 VAC receptacle that matches the plug.
The circuit must be equipped with delayed
action-type circuit breaker or fuses.

For example: Range is 80-100A,
set amperage to 100A.
NOTE: Amperage settings are
approximate. Adjust as necessary.
Other parameters like AC balance, pre-gas flow
time and post-gas flow time have been preset:
• Pre-Flow: The number of seconds that gas
will flow once the Foot Pedal is pushed – this
is preset at 0.3 seconds. The arc will not start
for that preset time, but gas will flow. Once
the preset time expires, the arc will start.
• Post-Flow: The number of seconds that gas
will flow once the Foot Pedal is released. This
has been preset and automatically adjusts
based on the preset amperage output.
WARNINg! TO pREVENT SERIOUS INJURy:
protective gear must be worn when using the
Welder; minimum shade number 10 full face shield
(or welding mask), ear protection, welding gloves,
sleeves and apron, NIOSH-approved respirator,
and fire resistant work clothes without pockets
should be worn when welding. Light from the

carefully following the DUTY CYCLE
guidelines as explained on page 14.
WARNINg! TO pREVENT SERIOUS INJURy: Metal
work bench must be grounded when TIg welding
(see High Frequency Grounding on page 6).
8. Hold TIG Torch in one gloved hand and
the TIG Rod in other gloved hand.
9. Specific Welding Techniques:
High Frequency Start
• Hold Torch away from the workpiece
the same distance as 1 to 1.5 times the
diameter of the Tungsten Electrode.
• Press Foot Pedal down slowly until arc
ignites. Then, press Foot Pedal down all
the way to reach maximum amperage. Let
up on Foot Pedal to lower amperage.
NOTE: Maintain a constant distance between the
Tungsten Electrode and the workpiece: between
1 and 1.5 times the diameter of the Electrode.
10. When welding puddle is hot enough, tilt torch
backward about 10-15 degrees from vertical and
move it back slightly. Add TIG Rod material as
needed to the front end of the weld puddle.
11. Alternate between pushing the torch/weld
puddle and adding the TIG Rod material.
NOTE: Back the TIG Rod off each time the Electrode
is advanced, but do not remove it from the gas shield.
This prevents oxidation from contaminating the weld.
12. When finished welding, release the Foot Pedal, but
keep Torch on weld puddle until gas flow ends.
13. Set TIG Torch down on nonconductive,
nonflammable surface away from
any grounded objects.

Welding Tips
A good way to test welding technique is to examine a weld’s appearance after it has
cooled and the slag has been removed (for Stick welds). Then, better welding can be
learned by adjusting your weld technique to remedy any problems found.
NOTICE: TIG welding is a complicated process, requiring experience and skill to achieve successful
results. Training beyond the scope of this manual is required to TIG weld properly.
After practice welding a couple
of welding beads, STOp and
examine your weld using
the following guidelines.
Strike Test
A test weld on a pIEcE OF ScRAp can be
tested by using the following procedure.
WEAR ANSI-AppROVEd SAFETy gOggLES
dURINg THIS pROcEdURE.
cAUTION! This test WILL damage the weld it is
performed on. This test is ONLy an indicator of weld
technique and is not intended to test working welds.
1. After two scraps have been welded together and the
weld has cooled, clamp one side in a sturdy vise.
2. Stay clear from underneath while you strike
the opposite side with a heavy hammer,
preferably a dead-blow hammer.
3. A gOOd WELd will deform but not break, as shown
on top.
A pOOR WELd will be brittle and snap

Limited One year Warranty
Harbor Freight Tools Co. makes every effort to assure that its products meet high quality and durability standards,
and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of one year from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS.
To take advantage of this warranty, the product or part must be returned to us with transportation charges
prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.
If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
