TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG 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 GRINDING
For optimal operation, it is recommended to use a sharpened electrode as follows:
d
L
a
a = Ø 0.5 mm
L = 3 x d for a low current.
L = d for a high current

1- Place the torch in the welding position above the part (distance of about 2-3 mm
between the electrode tip and the part).
2- Press the torch trigger (the arc starts without contact using High Frequency
impulsions).
3- The initial welding current circulates, the welding carries on according to the
welding cycle.

1- Position the torch nozzle and the tip of the electrode on the piece of metal and
press the trigger.
2- Position the torch to create a gap of roughly 2-3 mm between the tip of the
electrode and the metal. The arc starts.
3- Put the position back into position to start the welding cycle.
The arc priming and stabilization device is designed for manual and mechanically guided operation.
Warning:
increasing the length of the torch or earth return cables beyond the maximum length specified by the manufacturer will increase the risk
of electric shock.

TIG PROCESS SETTINGS
• The TIG DC is dedicated to the flow of ferrous metals such as steel, stainless steel, but also copper and its alloys and titanium.
• TIG AC is dedicated to the welding of aluminium and its alloys, but also copper.
• The Synergic TIG no longer works on the choice of a DC or AC current type and the settings of welding cycle parameters, but integrates experience-
based welding rules/synergies. This mode therefore restricts the number of settings to three basic settings:
- The type of material.
- The thickness to be welded.
- The welding position.
