• MMA PULSE
The MMA Pulsed mode is recommended for vertical-up welding (PF). The pulse mode keeps the weld pool cold and eases the transfer of matter. Wit
-
hout the pulse mode, vertical-up welding requires a difficult «Christmas tree» shape triangular movement. With the MMA Pulsed mode, this movement
is no longer required and a simple straight up movement is enough (depending on the thickness of the workpiece). If you wish to widen your weld
pool, a simple lateral movement is enough (similar to normal welding).
In this case the pulse current frequency can be adjusted on the display. This process allows greater control during vertical-up welding.

Recommendations:
• Low Hot start, for thin sheets, high Hot start for difficult-to-weld metals (dirty or oxidised).
• The Arc Force is set between -10 and +10. It needs to be combined with the choice of type of electrodes selected in the Advanced Menu (refer to
Advanced Menu section).

CONNECTIONS AND RECOMMENDATIONS
• The TIG DC welding requires gas shield protection of pure gas (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.
SELECT IGNITION MODE
TIG HF: High Frequency start without contact
TIG LIFT : Contact start (for environments sensitive to HF disturbances).
