Access to some welding parameter settings depends on the welding process used (synergy, AC or DC, etc.) and the selected display mode (Easy,
Expert or Advanced). Refer to the HMI manual. Some settings in % or A depend on the display mode selected (Easy, Expert or Advanced).

CONNECTIONS AND ADVICE
• Connect the cables, electrode holder and earth clamp to the socket connections.
• Respect the polarities and observe the welding currents indicated on the electrode's box.
• Remove coated electrodes from the electrode holder when the welding power source is not in use.
• This device is equipped with three Inverter-specific features:
- Hot Start provides an overcurrent at the beginning of the welding process.
- Arc Force delivers an overcurrent that prevents the electrode from sticking to the workpiece when the electrode enters the weld pool.
- The Anti-Stick feature means the electrode can be easily detached without allowing it to turn red if it becomes stuck.

Time for purging the torch and establishing the gas shielding before ignition
This start-up current is a warm-up phase before the current ramp-up.
Dwell time at start-up before ramping up
Allows a gradual increase in welding current
Welding current
Avoids cratering at the end of welding process as well as the risk of cracking, particularly in light alloys.
This stopping current is the phase after the current ramp down.
Stopping time is a phase after the down ramp in running
Thickness of the workpiece to be welded
Welding position
Gas shielding duration after extinguishing the arc. It protects the part and the electrode against oxidation
when cooling.

Alternating current (AC) waveform
Second «cooling» welding current
The pulse's hot current (I) time balance.
Pulse frequency between the welding current and the cold current:
PARAMETER SETTING TIPS:
• If welding with a manual filler metal, then F (Hz) is synchronised to the filler metal application movement.
• If the sheet metal is thin without a filler metal (< 0.8 mm), F (Hz) > 10 Hz.
• When welding in position, then F (Hz) < 100 Hz

The type of electrode determines specific parameters depen-
ding on the type of electrode used; this is in order to optimise
its weldability.
The Anti-Stick feature is recommended for safely removing
an electrode, it prevents it from sticking to the workpiece (the
current is automatically cut off).
