Abstract

A welding or additive manufacturing wire drive system includes a welding wire spool and first and second drive rolls. One or both of the drive rolls has a circumferential groove. The system includes a first welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove, and a second welding wire, drawn from the welding wire spool, and located between the drive rolls 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, and 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.
