A drive roll (180) adapted and configured to feed weld wire (54) comprises first and second opposing sides (238, 239) and an outer body surface (290). The outer body surface (290) comprises a base body surface (BBS), and at least one elevated wire interface (244) extending outwardly from and along at least a major portion of the base body surface. The elevated wire interface (244) can rotationally drivingly engage the weld wire (54), which enables the drive roll (180) to advance the weld wire (54) along e.g.a desired path of travel such as to a welding arc.
