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.

COATED ELECTRODE WELDING (MMA/SMAW)
• MMA/SMAW Standard
This MMA Standard welding mode is suitable for most applications. It can weld all type of electrodes : rutile, basic, cellulosic... and on any material:
steel, stainless steel, cast iron.

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.
T4
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.
Standard Pulse
The electrode type determines specific parameters according to
the type of electrode used in order to optimize its weldability.
Anti-sticking is recommended to safely remove the electrode if it is
stuck to the metal (the power is automatically cut off).
