Abstract
An apparatus and method for feeding welding wire, where the apparatus contains a wire feeding device which pays out a wire and a power source which provides a current and voltage to the wire while it is being paid out. The apparatus further includes a detection circuit which detects a short circuit in the wire when the wire makes contact with a work piece or the like, and upon detection of the short circuit the wire feeding device stops feeding the wire so that a desired stick out distance is achieved.
