WELDING SYSTEM WITH ROTATIONAL SPEED CONVERTER FOR AUXILIARY POWER GENERATOR AND METHOD OF OPERATING THE WELDING SYSTEM.

摘要

A welding system (300) includes an engine (310) having a rotational power output, an AC welding generator (315) operatively connected to the rotational power output for generating an AC current, a rectifying circuit (320) electrically connected to the AC welding generator (315) for converting the AC current to a DC output for welding, an auxiliary power generator (330) for supplying AC power to an auxiliary electrically powered device, and a rotational speed adjuster (335) coupling the auxiliary power supply (330) to the rotational power output and configured to drive the auxiliary power supply (330) at a different rotational rate than a rotational rate of the rotational power output. The invention further relates to a method of operating the welding system.
