Access to some of the welding parameters depends on the selected display mode: Settings/Display mode: Easy, Advanced or Expert. Refer to the
HMI manual.
MANUAL GAS PURGE
The presence of oxygen in the torch can lead to a decrease in mechanical quality and can result in less 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 (I-2) in the wire feeder.. Refer to the
HMI manual.

s Manual or time-controlled spot pulse phase
s Either manual or a set time.
s Avoids cratering at the end of welding and the risk of cracking, particularly in light alloys.
Pulse frequency (setting guidelines):
- If welding with manual filler metal, then the F(Hz) is synchronised to the filler action,
Hz
- If the metal is thin and without filler (< 0.8mm), F(Hz) > 10Hz
- If welding in position, then F(Hz) < 100Hz
s Allows a gradual increase in welding current.
Duration of the gas protection after the arc is extinguished. It protects the workpiece and the electrode from
s
oxidation during cooling.
s When the torch is bled and the gas shield is created before ignition.
s This idling time is a phase that comes after the current is lowered.
s Starting time before the current is raised.

Welding processes
Settings Standard
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.
T3 - The main button is pressed, the cycle goes to downslope and
stops in the I_Stop phase.
T4 - The main button is released, the cycle ends with the Post-Gas.
NB: for torches, double buttons and double button + potentiometer
=> «up/weld current» button turns on the potentiometer, the «down»
button turns it off.
T4
Pulsed
The type of electrode determines the settings in order to optimise its
weldability depending on the type of electrode used.
The anti-stick feature is recommended to safely remove the electrode in
the event of it sticking to the workpiece (the current is cut off automati-
cally).
