Setup for TIG Welding (GTAW) with Lift Arc
Setting up the equipment for TIG Welding (GTAW):
Lanthanated Tungsten 1/16" to 1/8" (MAX) recommended for use.
WARNING: TIG TORCH IS ALWAYS LIVE (ELECTRICALLY HOT).
the TIG torch is not in contact with or near conductive or grounded materials.
•
Press the PROCESS SELECTION BUTTON (1) on the front panel until the PROCESS INDICATOR LED (2) for DC
TIG welding (GTAW) is lit.
•
Connect the TIG torch cable to the NEGATIVE (-) DINSE SOCKET (10) of the welder.
•
Connect the ground cable connector to the POSITIVE (+) DINSE SOCKET (11) of the welder.
•
Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not
rusty or painted).
•
Connect the TIG torch gas line to the gas regulator (argon gas only).
THE GAS FLOW IS MANUALLY CONTROLLED WITH THE KNOB ON THE TIG
TORCH. USE INERT GAS (ARGON) ONLY.
TURN ON GAS AT THE GAS REGULATOR, THEN OPEN THE VALVE ON THE TORCH
HANDLE, CHECK FOR GAS FLOW AND ADJUST FLOW RATE AS NEEDED.
•
Fix the tungsten electrode so that it protrudes approximately ¼ inch from the torch nozzle.
•
Ensure the TIG torch is safely away from all conductive materials.
•
Switch the unit ON with the ON/OFF SWITCH (12).
•
Set the amperage with the AMPERAGE ADJUSTMENT KNOB (6).
•
Open the gas valve on the torch handle.
•
Initiate the weld arc with a lift arc technique.
•
Close the gas valve on the torch handle after post-weld flow has been completed.
REMEMBER TO CLOSE THE VALVE ON THE GAS CYLINDER IMMEDIATELY AFTER
ALL WELDING IS COMPLETED.

Welding Tips:
•
Always weld clean, dry and well-prepared material.
•
Move the torch smoothly and steadily as you weld.
•
Avoid welding in very drafty areas. A weak, pitted and porous weld will result due to drafts blowing away the
protective welding gas.
•
Sharp bends or kinks in the welding cable should be avoided.
•
Refer to the setup chart above for proper settings for the tungsten and work thickness.
Gas Selection
Use 100% argon gas when TIG welding with mild steel or stainless steel.
