ELECTRODE WELDING
• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode holder and earth clamp. Connect
the electrode holder and earth clamp as indicated on the electrode packaging.
• Respect the basic rules of welding.
• This device has 1 feature specific to Inverter machines :
- Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start, requires approximately a 3 seconds
delay before resuming normal welding operations.
TUNGSTEN ELECTRODE WELDING WITH INERT GAS (TIG)
CONNECTIONS AND RECOMMENDATIONS
TIG welding requires a torch as well as a gas bottle equipped with a regulator.
• Connect the earth clamp to the positive connector (+).
• Connect the torch’s earth cable to the negative plug (–).
• Connect the torch’s gas hose to the regulator’s output.
Ensure that the torch is equipped and ready to weld, and that the consumables (Vise grip, ceramic gas nozzle, collet and collet body) are not damaged.

Welding intensity settings :
Adjust the welding current using the central knob according to the diameter and the type of assembly to be carried out. The current setpoint is indi-
cated on the right side display.
ARC STRIKE / IGNITION :
LIFT start : Using the torch, make contact between the electrode and the metal piece, then slightly lift the electrode to start the arc.
WELD STOP / SWITCHING TO DOWNSLOPE :
To stop the weld, slightly lift the torch, the intensity will gradually reduce (downslope).
