MMA WELDING (ELECTRODE) INTERFACE ON PAGE 52
Mode MMA
• Your machine is equipped with 3 specific functions to Inverters :
- The Hot Start increases the current at the beginning of the welding.
- The Arc Force increases the current in order to avoid the sticking when electrode enters in melted metal.
- The Anti Sticking allows you to easily withdraw your electrode without damaging it in case of sticking.
1. Connect cables; electrode holder and ground clip in the connecting connectors,
2. Position the electrode on the electrode holder,
3. Select the MMA position (2) with the selector
4. Set the desired intensity using the
5. Set the «HOT START» and «ARC FORCE» by repeatedly pressing the button
Advice: :
• Low Hot Start: for thin metal sheets
• High Hot Start for metals that are difficult to weld (dirty or oxidized parts)
• Remove the electrode from the electrode holder when the equipment is not used.

1. Connect the earth clamp on the positive pole (+).
2. Connect a torch «valve» negative polarity (-).(Ref. 044425)
3. Connect the pipe gas torch on the gas cylinder
4. Select the TIG position (3) using the selector button
5. Adjust the wished current (display (1)) using the keys
Advice : Take 30A/mm as a default setting and adjust according to the part to weld.
6. Set the gas flow on flewmeter of the gas cylinder, and then open the valve of the
torch.
7. To boot : Touch the electrode on the welding part
8. At end of welding: Up 2 times the arc (up-down-up-down) to trigger the automatic
fade (see paragraph below). This movement must be performed in less than 4 sec,
at a height of 5 to 10 mm. Then close the valve to stop the torch gas after cooling
