A welding apparatus (100) is provided herein. The apparatus includes a wire source (110) having welding wire (105), a wire feed drive (115), and a wire pulser (120). The wire feed drive drives the welding wire from the wire source. The wire pulser has a first end associated with the wire feed drive and a second end associated with a wire conduit (125). The wire is fed through the wire conduit to a wire nozzle (130). The wire pulser increase and decrease the effective length of the wire as the wire moves through the wire conduit from the wire feed drive to the wire nozzle. |
