TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG/GTAW MODE)
CONNECTION AND ADVICE
• DC TIG welding requires gas protection (Argon).
• Connect the earth clamp to the positive connector (+). Connect the power cable to the negative plug (–), as well as the torch and the gas connec-
tions.
• Ensure that the torch is equipped and ready to weld, and that the consumables (Vice grip, ceramic gas nozzle, collet and collet body) are not
damaged.
ELECTRODE SHARPENING
For optimal operation, it is recommended to use a sharpened electrode as follows:
