ELECTRODE SHARPENING
For optimal operation, it is recommended to use a sharpened electrode as follows:
CHOICE OF ELECTRODE DIAMETER
Ø Electrode
(mm)
Pure tungsten
1 10 > 75 A
1.6 60 > 150 A
2 75 > 180 A
2.5 130 > 230 A
3.2 160 > 310 A
4 275 > 450 A
TIG/GTAW LIFT PRIMING
1 2
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.

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.
