Abstract
Welding power supplies, wire feeders, and systems to measure a weld circuit resistance via communications over the weld circuit are disclosed. An example welding-type power supply includes: a power conversion circuitry configured to: convert input power to output a signal via a weld circuit; and convert the input power to output welding-type power via the weld circuit; a voltage monitor configured to measure a power supply output voltage of the signal; communications circuitry configured to receive, via the weld circuit, a communication of a second voltage measurement; and control circuitry configured to: determine a resistance and/or and inductance of a portion of the weld circuit based on the power supply output voltage measurement, the second voltage measurement, and a weld circuit current.
