MANUAL GAS PURGE
Oxygen in the torch can lead to decreased mechanical performance and may result in a decreased corrosion-resistance level. To purge the gas from
the torch, press and hold push-button n°1 (see HMI user manual) and follow the on-screen procedure.

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.

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
