Claim Text:
1. A method, comprising: accessing, via a processor, data corresponding to a measured stud voltage and a current of a weld waveform that is generated during a welding operation; determining, via the processor, an overshoot voltage for the welding operation that exceeds an expected voltage level, wherein the overshoot voltage is determined based on a ramp rate of the current of the weld waveform; calculating, via the processor, based on the overshoot voltage and the measured stud voltage, a compensated stud voltage for the welding operation; and controlling, via the processor, welding power configured to compensate for effects of inductance based on the compensated stud voltage for the welding operation, wherein at least part of the compensation for inductance is performed without reference to a voltage measured by a voltage sensing lead.
