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.
