Abstract
A welding system includes an inductor on an output of a welding power supply. The power supply may be of the type including an engine and a generator for producing power, with power conversion circuitry conditioning the power to a form suitable for a stick welding application. The inductor has an inductance sufficient for storing energy for maintaining a welding arc with XX10 electrodes, such as on the order of 700 mH. The inductor may have a particular structure, such as one designed around T and L shaped core elements.
