ABSTRACT:
A welding system is disclosed having an alternator which includes two overlapping delta configuration three-phase stator windings of differing gauge. An ordinary welding rod may be utilized or, a supply or consumable welding wire may be coupled to the output of the alternator and advanced by means of a wire feeder in response to the actuation of a trigger control. A control circuit is then utilized to selectively activate a rotatable electric field winding within the alternator in response to the actuation of the trigger control such that the welding wire is "hot" only during actual welding operations.
