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.

Abstract: A rotor for a generator comprises a stack of laminate plates and conductive end caps on either side thereof. The laminate plates and the end caps have holes near a periphery thereof, and conductive rods are positioned in the holes, and secured to the end caps. The stack, the end caps and the rods are then skewed by a desired angle with respect to a centerline of the rotor. The resulting rotor core may then be mounted to a rotor shaft, and wound, with the windings also being skewed due to skewing of the core. The end caps and rods form a damper cage that aids in reducing harmonics.

Abstract: An engine-driven welder generator is controlled based upon power draw for welding and other applications. Once a welding arc is initiated, the power draw is monitored. The engine speed, and therefore the power output of the generator, may be increased or maintained based upon the power draw. The power draw may include both welding power draw and auxiliary power draw. The engine speed is increased in increments. The initial engine speed and subsequent increments may depend upon particular welding processes or regimes.
