Abstract
A novel system for mounting welding wire spools of different sizes on a mounting spindle of a wire feed system is provided. The invention may reduce or eliminate wire feedability difficulties and welding arc outages arising from misalignment of the wire spool and inconsistent wire feeds. The invention provides a medium and large wire spool mounting system including a spool mounting hub, a movable back plate configured with a locking slot arrangement, and a left threaded nut plate. Furthermore, the invention provides a system for mounting small wire spools on a keyed shaft of a wire feed system comprised of washers, a spring, and a knurled nut. A braking system including washers, a spring, and a knurled nut is provided for the prevention of wire spool free wheeling during non-welding periods.
