Abstract
A welding or additive manufacturing wire drive system includes a spindle. First and second welding wire spools are mounted on the spindle. The spools include a flange, a mounting hub, a barrel, and a wire electrode wound on the barrel. At least two drive rolls simultaneously draw first and second wire electrodes from the spools. A clutch disk is mounted on the spindle and has respective frictional surfaces in contact with one or both of the flange and mounting hub on the spools to frictionally engage the spools. The clutch disk allows the spools to slip relative to each other during an operation of the at least two drive rolls such that the spools rotate at different speeds while the wire electrodes are drawn from the spools.
