Abstract
The subject embodiments relate to a wire feed system that is used with a welder. The wire feed system includes a pair of counter-rotating discs disposed along a common longitudinal axis that are spaced apart a first width. A first disc rotates in a first direction and a second disc rotates in a second direction which is opposite the first direction. A drive roll is disposed between the first disc and the second disc within the first width. An engaging member moves the drive roll adjacent to either the first disc or the second disc based on a predetermined condition to advance or retract wire relative to a workpiece within the welding system.
