Machine description – quick overview
Description 0
DC welding with positive polarity on the
electrode holder in relation to the work-
piece (pole reversing switch, MMA only).
DC welding with negative polarity at the
torch (or electrode holder) with respect
to the workpiece.
AC welding with rectangular current out-
put wave form. Maximum power loading
and safe welding.
AC welding with trapezoidal current out-
put wave form. An all-rounder, suitable
for most applications.
AC welding with sinusoidal current out-
put wave form. Low noise level.
