A welding or additive manufacturing wire drive system includes a first spindle for a first welding wire spool, a second spindle for a second welding wire spool, a first drive roll, and a second drive roll. One or both of the drive rolls has a circumferential groove. A first welding wire and a second welding wire are located between the first drive roll and the second drive roll in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove. The second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.
