Crater fill
When welding with high power, a crater is usually formed at the end of the weld. The Crater fill function
gradually decreases the welding power/ wire feed speed at the end of the welding job so that the crater can
be filled using a lower power level.
When the 2T trigger logic is in use, releasing the trigger launches the Crater fill sequence.

1.
Trigger is pressed.
2.
Trigger is released.
When the 4T or WP Switch is in use, pressing the trigger during the welding (in the case of WP Switch,
pressing > 0.5 s) launches the Crater fill sequence. The system stays on the Crater fill finishing level until the
trigger is released. Releasing the trigger immediately finishes the Crater fill sequence.
