ABSTRACT:
A method and apparatus for feeding wire from a source of wire to a weld includes one or more motors disposed adjacent the wire to drive the wire to the weld. A buffer is disposed between the source and an arc end of the torch. Another motor may be disposed near the wire source.A wire tension controller may be provided. The one or more motors advance and retract the wire, and wire is stored, or the path length altered, when the wire is retracted.
