Abstract
A drive roll adapted and configured to feed weld wire includes first and second opposing sides and an outer body surface. The outer body surface includes a base body surface, and at least one elevated wire interface extending outwardly from and along at least a major portion of the base body surface. The elevated wire interface can rotationally drivingly engage the weld wire, which enables the drive roll to advance the weld wire along e.g. a desired path of travel such as to a welding arc.
