Title:
INDUCTOR WITH L AND T SHAPED CORE ELEMENTS WITH SPACERS AND COMBS; SYSTEM FOR WELDING AND METHOD OF WELDING USING AN INDUCTOR FOR MAINTAINING WELDING ARCS
Document Type and Number:
WIPO Patent Application WO/2014/039178
Kind Code:
A3
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 (62, 64).
