Wear a NIOSH-approved respirator
to avoid breathing arc fumes.
Stroke the area to be welded with the 11.
Electrode to ignite the arc. Never tap
the Electrode into the welding sur-
face to ignite the arc. This damages
its external coating on the Electrode
which prevents oxygen in the air from
coming into contact with the molten
metal, causing it to oxidize.
Once the arc is ignited, tilt the Elec-12.
trode forward at an angle of approxi-
mately 30° and hold it at a distance
from the welding object equal to the
diameter of the Electrode.
NOTE:13. If too much current is drawn
from the Welder, the internal Thermal
Overload Protector will activate. The
Yellow “Overheating” Light (5) will
illuminate, and the Welder will auto-
matically shut off until it cools down.
Please wait until the welder automati-
cally restarts after the yellow “over-
heating” light turns off.
(See Figures B and C.)
When the weld is complete, lift the 14.
Electrode clearly away from any
grounded object. Then turn the
Power Switch (16) OFF.
(See Figure C.)
Unplug the Power Cord (17) from its 15.
electrical outlet.
Remove the Ground Clamp (9) from 16.
the workpiece it is clamped onto.
Then remove the Electrode from the
Electrode Holder (8).
(See Figure A.)
Allow all components of the Welder 17.
to completely cool. Then clean and
store the Welder indoors out of reach
of children and other unauthorized
persons.
IMPORTANT: Refer to the included 18.
“Weld Diagnoses” pamphlet for tips
and suggestions regarding proper
welding.
TIG Torch Operating Instructions
Please Note: The
following
instructions are for Tig
Welding using the Tig Torch.
TO PREVENT SERIOUS
INJURY AND DEATH:
Do not touch the tip of the
Torch when the welder is
connected to power. The
Torch will immediately
activate when it is plugged in.
The operator must carefully
direct the torch whenever
the welder is connected to
power. When the operator is
not holding the Torch, it must
be sitting on a nonconductive,
nonammablesurface.

To use Tig Torch, rst disconnect 1.
Electrode Holder (8).
Attach the welder’s Ground Clamp 2.
to a clean uncoated metal part of the
workpiece near the welding location.
Close the Gas Flow Knob on the 3.
torch completely, turning it clockwise
until it stops. Turn the argon gas sup-
ply on.
Hold the torch in a safe direction4. ,
