Abstract
A welding power supply includes an ac generator with a field winding and a welding output winding. An electronic field controller receives current and voltage feedback from the welding output. This electronic field controller is connected to the field winding, controlling the current through this winding in such a way that the volt-ampere output curve at the welding output winding consists of a plurality of selected nominal output current curves, each of these curves including at least two breakpoints.
