TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG MODE)
CONNECTIONS AND RECOMMENDATIONS
• The TIG DC welding requires gas shield protection of pure gas (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 connections.
• 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 da-
maged.
• The electrode choice depends on the TIG DC process current.
ELECTRODE GRINDING
For optimal operation, it is recommended to use a sharpened electrode as follows:

Pulsation frequency of the PULSE mode.
The incrementation step depends on the frequency range:
Pulse frequency
0.4 Hz - 3 Hz
3 Hz - 20 Hz
The Arc Force is an overcurrent delivered when the electrode or drop comes into contact with the
solder bath in order to avoid sticking.

Recommendations
The anti-sticking feature is recommended to safely remove the electrode
in case it is stuck to the metal.
The duration of the HotStart can be adjusted to make the arcing easier
when using difficult electrodes.
