MODE SELECTION AND SETTING
Press the switch
Setting the welding current :
Adjust the welding current using the central knob
work to be carried out. The current setpoint is indicated on the central side
display.
WELDING CURRENT SETTINGS
The following settings concern the current range that may be used depending on the electrode's type and diameter. These ranges are
quite large as they depend on the application and the welding position.
Ø electrode (mm)

ELECTRODE WELDING
• The reverse polarity cable must be disconnected in MMA (stick welding) mode in order to connect the electrode holder and earth
clamp. Connect the electrode holder and earth clamp as indicated on the electrode packaging.
• Respect the basic rules of welding.
• This device has 1 feature specific to Inverter machines :
- Anti-Sticking: Enables easy removal of the electrode from the metal. The anti-sticking feature, after its start, requires approxima-
tely a 3 seconds delay before resuming normal welding operations.
PROTECTION AND RECOMMENDATIONS
1 - Overheating:
This unit is equipped with a ventilation system regulated by the temperature of the device. When the unit switches to thermal
protection, it no longer delivers any current. The orange LED (fig. V-1) lights up until the temperature of the unit has returned to
normal.
• Ensure the ventilation holes of the unit are not blocked to allow adequate air circulation.
• Leave the unit switched on after welding and during thermal protection to allow cooling.
2 - Overcurrent:
This unit is equipped with a primary current measurement. In case of overcurrent, the orange LED (fig. V-1) lights up. In this case
the unit must be switched off and restarted.
3 - Observations:
• Respect the basic rules of welding.
• Ensure that there is sufficient ventilation.
• Do not work on a damp surface. To prevent gas leaks, use the clamps supplied in the accessory box.
- Make sure that the gas cylinder is held in place with the fixing collar, see fig. V.
- Set the gas flow rate by adjusting the control dial on the pressure regulator.
