Abstract
A welding or additive manufacturing wire drive system includes a first drive roll and a second drive roll. One or both of the drive rolls has a circumferential groove for simultaneously driving both of a first wire electrode and a second wire electrode located between the drive rolls in the circumferential groove. A sensor device generates a signal or data corresponding to a consumed or remaining amount of one or both of the wire electrodes. The first wire electrode contacts the second wire electrode within the circumferential groove. The first wire electrode further contacts a first sidewall portion of the circumferential groove. The second wire electrode further contacts a second sidewall portion of the circumferential groove. Both of the wire electrodes are offset from a base portion of the circumferential groove, said base portion extending between the first sidewall portion and the second sidewall portion of the circumferential groove.
