• Welding in E.TIG mode
This mode allows constant power welding by measuring arc length variations in real time to ensure constant bead width and penetration. In case the
assembly requires the welding power to be controlled, the E.TIG mode can be used as it is designed to ensure that the welding power remains the
same regardless of the position of the torch.

T1 - The main button is pressed, the welding cycle starts (PreGas,
I_Start, UpSlope and welding).
T2 - The main button is released, the welding cycle is stopped
(DownSlope, I_Stop, PostGas).
For the double button torch and in 2T mode only, the secondary
button works like the main button.
T1 - The main button is pressed, the cycle starts at PreGas and
stops in the I_Start phase.
T2 - The main button is released, the cycle continues in UpSlope
and in welding.
T3 - The main button is pressed, the cycle switches to DownSlope
and stops in I_Stop.
T4 - The main button is released, the cycle ends with PostGas.
Nb : for torches, double button and double button with potentiome-
ter
=> command « up/welding current » and active potentiometer,
command «low » inactive.
