“Welding current polarity” button
Direct current welding with positive polarity on the electrode holder in
relation to the workpiece (pole reversal switch, MMA only).
DC welding with negative polarity on the torch (or stick electrode holder)
in relation to the workpiece.
Alternating current welding with rectangular current output wave form.
Maximum power loading and safe welding.
Alternating current welding with trapezoidal current output wave form.
The all-rounder for most applications.
4
Alternating current welding with sinusoidal current output wave form.
Low noise level.
