1st cycle
• Press torch trigger 1, the gas pre-flow time elapses.
• HF ignition pulses jump from the electrode to the workpiece, the arc ignites.
• Welding current flows and immediately adopts the ignition current value set (search arc at minimum
setting). HF is switched off.
2nd cycle
• Release torch trigger 1.
• The welding current increases in the set up-slope time to the main current AMP.
Pressing torch trigger 1 starts the slope (tS1) from main current AMP to secondary current
AMP%. Releasing the torch trigger starts the slope (tS2) from the secondary current AMP% back
to the main current AMP. This process can be repeated as often as required.
The welding process is ended by the arc interruption in the secondary current (removing the
torch from the workpiece until the arc is extinguished).
The slope times can be set- See 5.19 Machine configuration menu chapter.
This operating mode needs to be activated- See 5.19 Machine configuration menu chapter
section.
