POWER SUPPLY – STARTING UP
• The welders are fitted with a 32 A socket type EN 60309-1 which must be connected to a three-phase 400V (50 - 60 Hz) power supply fitted with
four wires and one earthed neutral.
The absorbed effective current (I1eff) is displayed on the machine, for optimal use. Check that the power supply and its protection (fuse and/or
circuit breaker) are compatible with the current needed by the machine. In some countries, it may be necessary to change the plug to allow the use
at maximum settings.
• The machine ie designed to work on a 400V +/- 15% power supply.
• The device turns into protection mode if the power supply tension below 340V RMS or over 460V RMS. To signal this fault, the screen displays an
error code.
• The start is done via an on / off switch (7) set to I, and the stop is done by switiching it to O. Attention ! Never disconnect the power supply
when the machine is on.
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 400Vac ±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.

MODE SELECTION
Press the button several times until the LED light switches on below the symbol
The MMA vertical up mode adds a current pulse which makes vertical up welding easier.
MAIN SETTINGS
1. Selection of the electrode's coating type :
Selection of the electrode's coating type by maintaining the
symbol.
2. Welding intensity settings :
Adjust the welding current using the main knob
setpoint is indicated on the right side display.
3. Arcforce settings :
Adjust the arcforce level with the right side knob
The higher the arcforce, the higher the extra welding current . The default value is 0.
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.
