Abstract

A method is performed in a welding or cutting system including a power supply configured to deliver current pulses through a weld circuit to a contact tip extending from a welding torch to create an arc on a workpiece. The method includes: while the contact tip is shorted to the workpiece to set an arc voltage equal to zero: sampling a current pulse to produce current values; and at a voltage sense point, on the power supply or the weld circuit, that is spaced-apart from the welding torch, sampling a voltage pulse associated with the current pulse to produce voltage values that differ from the arc voltage due to an electrical circuit parameter of the weld circuit; and computing a value of the electrical circuit parameter based on the current values, the voltage values, and the arc voltage equal to zero.
