Patent number: 12090585Abstract: Systems and methods for cleaning a wire electrode after a welding process has ended are described. During a welding process, a wire electrode may be fed forward from a wire feeder through a welding torch to create a molten weld pool. While, conventionally, feeding of the wire electrode stops when the welding process ends, the present disclosure contemplates instead continuing to feed the wire electrode forward after the welding process ends. More particularly, the present disclosure contemplates feeding the wire electrode into the weld pool so that the wire electrode can be “cleaned” in the molten weld pool created by the welding process. The “cleaned” wire electrode end can be more easily used to establish an electrical arc at the beginning of the next welding process.Type: GrantFiled: July 18, 2022Date of Patent: September 17, 2024Assignee: ILLINOIS TOOL WORKS INC.Inventor: James Lee Uecker
