<Note>
Wire retract at welding end:
Wire retract (feed backward) amount is determined by [“AMP”] x [”DELAY” for WIRERWD OFF].
Some welders ignore the welding current command during the burn back time. If so, the wire may hardly be
retracted. In such case, set the DELAY for the torch switch OFF to 1.2 seconds or more to ensure the wire retract
after the burn back operation.
