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 (+). Plug the TIG torch (ref. 046108) into the EURO connector of the generator and the inversion
cable into the negative connection connector (-).
• 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:
d
L
a
a = Ø 0.5 mm
L = 3 x d for a low current.
L = d for a high current

TIG/GTAW LIFT PRIMING

1- Position the torch nozzle and the tip of the electrode on the metal piece 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 stabilisation feature is designed for manual and mechanically guided operation.
Warning:
Increasing the length of the torch or return cables beyond the maximum length specified by the manufacturer will increase the risk of
electric shock.
TIG/GTAW 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.
• The Synergic TIG no longer works on the choice of a DC 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.
