En 4T pulse, la gâchette gère le Pré-gaz s'il n'y a pas de HotStart. Sinon elle permet de gérer la durée du HotStart, s'il est validé.v During the shu-
tdown, it allows to manage the Crater filler, if it is validated or the Post gas if there is no Crater filler.
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:
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

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.
