For double button or double trigger torches, the «high» trigger retains the same functionality as the single trigger or lamella torch. The «low» trigger
is inactive.
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.
CHOICE OF COATED ELECTRODES
• Rutile electrode: very easy to use in all positions.
• Basic electrode: usable in all positions, it is suitable for structural work thanks to increased mechanical properties.
• Cellulosic electrode: very dynamic arc with a high melting rate and usable in all positions making it especially suitable for pipe work.

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
- the secondary button is kept released, the welding current swit-
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.
