COATED ELECTRODE WELDING (MMA)
CONNECTIONS AND RECOMMENDATIONS
• Connect the cables, electrode holder and earth clamp to the connectors,
• Follow the welding polarities and power recommendations indicated on the electrodes 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 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 STANDARD mode is recommended for most applications. It can weld any type of electrode: rutile, basic, cel-
lulosic... and on any materials: steel, stainless steel, cast iron.
Activating the MMA mode and setting the intensity:
MMA
OK
To set the Hot Start, follow these steps :
Recommendations:
- Low Hot start, for thin sheets
- High Hot start for difficult-to-weld metals (dirty or oxydised)
OK
To set the Arc Force, follow these steps :
Advice:
The Arc Force is manually adjustable from 0 to 90% or choice of electrode is possible (Rutile, Basic or Cellulosic) by
continuing the adjustment beyond 90%.
- Low Arc Force, for rutile and stainless steel electrodes
- High Arc Force, for basic, cast-iron and cellulosics electrodes
