Special 4-step
mode:
variant 5
Variant 5 of the special 4-step mode is activated when the SFS set-up parameter is set to
"5".
Variant 5 allows the welding current to be increased and reduced without an up/down weld -
ing torch.
- The longer the torch trigger is held in the forward position during welding, the more the
welding current increases (up to the maximum).
- The welding current remains constant when the torch trigger is released.
- The longer the torch trigger is pushed forward again, the more the welding current de -
creases.

: briefly
press (< 0.5 s) and release the torch trigger
- End the welding process: press the torch trigger for longer (> 0.5 s) and release.
The process is automatically ended after the downslope phase and the final current phase.
If the torch trigger is pressed briefly (< 0.5 s) and released during either the downslope
phase or the final current phase, then an upslope will take effect until it reaches the main
current and the welding process will continue.
