TIG
MIG
Control adjusts inductance for MIG welding.
Set Arc Control to desired wire type. Inductance
determines the “wetness” of the weld puddle.
As setting is increased (rotating Arc Control
clockwise), wetness (puddle fluidity) increases.
For best results, preset Arc Control to the wire
type. Then either increase or decrease setting
within wire type scale to make fine adjustment
to the welding arc.
