For dual button or dual trigger torches, the «high» trigger retains the same functionality as the single trigger torch . The «low» trigger is not active.
MANUAL GAS FLUSHING
The presence of oxygen in the torch can lead to a decrease in mechanical quality and can result in less corrosion resistance. To flush the gas from
the torch, press and hold the button #1 and follow the on-screen procedure.

Access to certain welding settings depends on the welding process (Standard, Pulsed, etc.) and the selected display mode (Easy, Expert or Ad-
vanced).
MMA (SMAW) WELDING MODE
INSTALLATION AND GUIDANCE
• Plug the cables, electrode holder and earth clamp into the plug connections.
• Respect the electrical polarities and the strength of the welding power indicated on the electrode boxes.
• Remove the coated electrode from the electrode holder when the welding power source is not in use.
• The equipment is fitted with 3 inverter-specific features:
- Hot Start provides an overcurrent at the beginning of the welding process.
- Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Stick technology makes it easier to unstick the electrode from the metal.

SET-UP TIPS:
Hz - If welding with a manual, filler metal, then F(Hz) is synchronised to the inputting of the wire.
- If the metal is thin and without filler (< 0.8 mm), F(Hz) > 10 Hz
- If welding in position, then F(Hz) < 100 Hz

T1 - The main button is pressed, the cycle starts from Pre-Gas and
stops at the I_Start phase.
T2 - The main button is released, the cycle continues to upslope
and welding.
LOG: this operating mode is used during the welding phase:
- a quick press of the main button (<0.5 s) switches the current from
I_welding to I_cold and vice versa.
- if the secondary button is pressed, the current switches from
I_welding to I_cold.
- if the secondary button is left unpressed, the current switches from
I_cold to I_welding.
T3 - After holding down the main button (>0.5 s), the cycle goes into
downslope and stops at the I_Stop phase.
T4 - The main button is released and the cycle ends with Post-Gas.
