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 PURGE
The presence of oxygen in the torch can lead to a decline in mechanical performance, resulting in reduced corrosion resistance. To purge the gas
from the torch, press and hold push-button no.1 and follow the procedure on the display, or press the purge switch (II-12) in the wire feeder. Refer to
the HMI manual.

Time taken to purge the torch and create gas protection before ignition.
This start-up current is a pre-heating phase before the current upslope.
Start-up plateau time before the current upslope.
Allows a gradual increase in welding current.
Welding current.
Avoids cratering at the end of a weld and the risk of cracking, particularly in light alloys.
This static level current is the next phase after the downslope in current.
This static level current is the phase after the current downslope.
Thickness of the workpiece to be welded.
Welding position
Duration of the gas protection after the arc is extinguished. It protects the workpiece and the electrode from
oxidation during cooling.
Pulse waveform.
Secondary welding current known as a «cold» current.
Balance between hot current time (I) and pulse duration
Pulse frequency
SET-UP TIPS:
- If welding with manual filler metal, then the F(Hz) is synchronised to the filler action,
- If the metal is thin and without filler (< 0.8mm), F(Hz) > 10Hz
- If welding in position, then F(Hz) < 100Hz
Manual or a set duration.
Pulse phase manual or defined duration
Manual or timed smooth current phase
T1 - The main button is pressed, the cycle starts from the PreGas
and stops in the I_Start phase.
T2 - The main button is released, the cycle continues to upslope
and welding.
LOG: this function is used during the welding phase:
- a brief press on the main button (<0.5s) 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 begins to
downslope and stops at the I_Stop phase.
T4 - The main button is released and the cycle ends with Post-Gas.
