ABSTRACT:
An adapter enables a conventional MIG welding machine to successfully use spoked wire wheels on which weld wire is wound. The adapter assembles over a rotatable hub that is also conventional. The adapter has a notch that mates without backlash with a post on the hub, thereby assuring that the hub and adapter rotate together. The adapter also has tabs that engage spokes of the wire wheel without backlash. Accordingly, the wire wheel and hub rotate together without backlash. A frictional drag on the hub is transmitted by the adapter to the wire wheel, so that normal operation of the welding machine does not cause wire wheel coasting and unraveling of the weld wire. The adapter allows field retrofit of existing welding machines so they can use the wire wheel in place of prior wire spools. In a modified embodiment, the adapter is made of two parts that are angularly adjustable relative to each other to enable the adapter to engage the spokes of different wire wheels.
