• Press the PROCESS SELECTOR BUTTON on the front panel to the middle position.
• Remove the MIG ELECTRODE POLARITY JUMPER from the POSITIVE (+) and NEGATIVE (-) DINSE SOCKETS.
• Check the electrode packaging to determine the recommended polarity and connect the electrode holder and
ground clamp to the POSITIVE (+) and NEGATIVE (-) DINSE SOCKETS accordingly.
• Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not
rusty or painted).
• Switch the unit ON with the ON/OFF SWITCH.
• Set the amperage with the LEFT KNOB.
Setting up the Equipment for TIG Welding (GTAW):
Lanthanated Tungsten recommended for use.
WARNING: TIG TORCH IS ALWAYS LIVE (ELECTRICALLY HOT). Use caution and ensure the TIG
torch is not in contact with or near conductive or grounded materials.
• Switch the PROCESS SELECTOR BUTTON on the front panel.
• Remove the MIG ELECTRODE POLARITY JUMPER from the POSITIVE (+) and NEGATIVE (-) DINSE SOCKETS.
• Connect the TIG torch cable to the NEGATIVE (-) DINSE SOCKET of the welder.
• Connect the ground cable connector to the POSITIVE (+) DINSE SOCKET 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).
USE INERT GAS (ARGON) ONLY.
TURN ON GAS AT THE GAS REGULATOR, 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.
• Set the amperage with the LEFT KNOB.
• Initiate the weld arc with a lift arc technique.
REMEMBER TO CLOSE THE VALVE ON THE GAS CYLINDER IMMEDIATELY AFTER ALL
WELDING IS COMPLETED.
