Abstract
An example wire feeder includes: a frame; a receptacle configured to transfer welding-type current to a welding torch via a torch connector, and to position the torch connector to receive a wire electrode; one or more drive rolls configured to drive the wire electrode to the welding torch, the one or more drive rolls being electrically insulated from the frame, and wherein the wire electrode is electrically insulated from the frame; and a sensor configured to determine at least one of a voltage or an impedance between a first point electrically coupled to the wire electrode and a reference point.
