Arc Force
ADJUSTMENT TIPS
• Low hot start for thin sheets and high start for thicker and more difficult metals (dirty or oxidized parts).
• The Arc Force can be adjusted from -10 to +10 manually or an electrode selection is possible (Rutile, Basic or Cellulosic) by conti-
nuing the adjustment beyond +10. Arc Low force, for rutile electrodes, stainless steel. Strong arc force, for basic, cast iron and cellulo-
sic electrodes.
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:

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.

The Arc Force is an overcurrent delivered when the electrode or drop comes into contact

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.
