Parameter
Description
Welding Current This parameter sets the welding current.
Spot Time
MIG only. The welding current can be set, and be controlled according to the setting
time. This mode of welding is used to melt the top & bottom plates together to form a
nugget between them.
Burnback Time
MIG only. Burnback time is the difference between the wire feed motor stopping and
switching off of the welding current. The Burnback time allows the electrode wire to
burn out of the molten metal weld pool, to separate the electrode wire from work piece.
