Abstract
Welding power supplies, wire feeders, and systems to measure a weld cable voltage drop are disclosed. Example welding-type power supplies include a power converter configured to convert input power to output welding-type power to a remote device via a weld cable; a reference conductor connected between the power supply and the remote device; a voltage monitor configured to determine a first voltage between the weld cable and the reference conductor while substantially zero current is being conducted through the reference conductor; and a receiver circuit configured to receive a second voltage between the weld cable and the reference conductor from the remote device.
