ELECTRODE WELDING (MMA)
CONNECTIONS AND RECOMMENDATIONS
• Connect the electrode holder and earth clamp to the corresponding sockets.
• Ensure that the welding polarities and intensities indicated on the electrode packaging are observed.
• 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 welding.
- The Arc Force creates an overcurrent which prevents the electrode from sticking to the weld pool.
- The Anti-Sticking technology makes it easier to unstick the electrode from the metal. .
MMA WELDING PROCESSES
• MMA STANDARD
The MMA STD mode is recommended for most applications. It can weld any type of electrode : rutile, basic, cellulosic... and on any material: steel,
stainless steel, cast iron.

Recommendations:
• Low Hot start, for thin sheets, high Hot start for difficult-to-weld metals (dirty or oxidised).
• The Arc Force is set between -10 and +10. It needs to be combined with the choice of type of electrodes selected in the Advanced Menu (refer to
Advanced Menu section).
