1. A system for mounting welding wire spools of different sizes on a mounting spindle of a wire feed system, comprising: a hub having a central portion for holding wire spools of different sizes, a first end having a locking slot arrangement formed in an outer surface thereof, and a threaded second end, wherein the locking slot arrangement comprises a central axial slot, at least one circumferential extension, and at least one axially disposed locking recess; a first plate configured to slide axially through the central axial slot, to slide circumferentially through the circumferential extension, and to slide axially into the axially disposed locking recess to lock within the locking slot arrangement of the first end to limit movement of a wire spool when disposed on the hub and to substantially prevent circumferential rotation of the first plate; and a second plate configured to be threaded onto the second end to hold the wire spool between the first and second plates.
