Patent

CA 2303738

A method and apparatus for providing a welding output and an auxiliary output from a generator having a field winding, an auxiliary output winding and a welding output winding is disclosed. One or both of a welding output and an auxiliary output are detected, and feedback signals indicative of the presence or absence of one or both of a welding output and an auxiliary output are provided. A controller, preferably an electronic field controller includes an auxiliary output regulator enabled or disabled by the output detector feedback signal and a welding regulator enabled or disabled by the output detector feedback, such that one and only one of the auxiliary output regulator and welding regulator is enabled. The auxiliary output regulator is connected to an auxiliary output feedback circuit, thereby providing closed loop control, preferably with a CV output. A maximum auxiliary power output is available in the absence of the welding output, and less then the maximum auxiliary power output is available in the presence of the welding output.
