• 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.

For this mode it may be convenient to use the dual button torch option or dual button with potentiometer. The «up» command keeps the same func-
tion as the single button or trigger torch. The «down» button can, when pressed, switch to the cold current. The potentiometer of the torch, where
available, can control of the welding current from 50% to 100% of the value displayed.
ELECTRODE WELDING (MMA/SMAW)
CONNECTION AND ADVICE
• Connect the cables, electrode holder and earth clamp to the connectors.
• Observe the welding polarities and intensities indicated on the electrode boxes.
• Remove the electrode from the electrode holder when the machine is not in use.
• The machine has 3 features exclusive to Inverters:
- The Hot Start creates an overcurrent at the beginning of the weld.
- The Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Sticking makes it easier to unstick the electrode from the metal.

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.
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.
LOG : this mode is used during welding :
- A brief press of the main button (<0.5s), the current switches
from I welding current to I cold and vice versa.
- the secondary button is kept pressed, the welding current swit-
ches from I welding current to I cold
T4 - the secondary button is kept released, the welding current swit-
T4
ched from I cold to I welding current.
T3 – A long press on the main button (>0.5s), the cycle switches to
DownSlope and stops in the I_Stop phase.
T4 - The main button is released, the cycle finishes with PostGas.
