Abstract: A pusher system (12) extracts a wire (11) from a reservoir (10) and feeds the wire through a wire guide (13) to a puller system (14). The puller system then feeds the wire (11) through a tip (15) to the welding operation represented by an arc (16) and a work piece (17). The pusher system (12) has a motor (20) adjusted so as to feed the wire (11) at the desired rate. A pair of rollers (22), which are driven by the motor (20), are designed to slip on the wire (11) if the wire becomes jammed or blocked. The puller system (14) has a limited torque motor (30). The limited torque motor (30) drives a pair of rollers (32) which firmly grip the wire (11) and do not slip on the wire (11). If the wire (11) becomes blocked or jammed then the motor (30) will stall. The combination of the pusher system (12) and the puller system (14) provides a wire feeder which does not damage the wire (11) and which does not cause birdnesting if the wire is jammed or blocked.
