CONNECTION ON A GENERATOR

The machine can work with generators as long as the auxiliary power matches these requirements :

- The voltage must be AC, always superior to 400 Vac ±15%, and the peak voltage below 700V,

- The frequency must be between 50 and 60 Hz.

It is imperative to check these requirements as several generators generate high voltage peaks that can damage these machines.

USE WITH EXTENSION CABLES

All extension cables must have an adequate size and section, relative to the machine's voltage .

Use an extension that complies with national safety regulations.

ELECTRODE WELDING (MMA)

CONNECTIONS AND RECOMMENDATIONS

• Connect the cables, electrode holder and earth clamp in the connectors,

• Respect the welding polarities and intensities indicated on the electrodes boxes,

• Remove the electrode from the electrode holder when the machine is not in use.

The grey areas are not useful for this mode.

MAIN SETTINGS

1. Welding intensity settings :

Adjust the welding current using the central knob according to the electrode diameter and the type of assembly to be carried out. The current setpoint

is indicated on the right side display.

2. Arcforce settings :

Adjust the arcforce level with the left side knob. The lower the arcforce level, the softer the arc will be. The higher the arcforce level, the higher the

welding overcurrent will be. It is recommended to set the arc force in median position to start the welding and adjust it according to the results and

welding preferences. Note : the arcforce setting range is specific to the selected electrode type.

3. Hot Start settings :

Adjust the Hot Start level with the right side knob. Low Hot start, for thin sheets and High Hot start for difficult-to-weld metals (dirty or oxydised).

WELDING PARAMETERS

WELDING INTENSITY SETTINGS

The following settings concern the intensity 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.
