Patent number: 7390989Abstract: A drive roll adapted and configured to feed weld wire includes first and second opposing sides and an outer body surface. The outer body surface includes a base body surface, and at least one elevated wire interface extending outwardly from and along at least a major portion of the base body surface. The elevated wire interface can rotationally drivingly engage the weld wire, which enables the drive roll to advance the weld wire along e.g. a desired path of travel such as to a welding arc.Type: GrantFiled: April 8, 2004Date of Patent: June 24, 2008Assignee: Illinois Tool Works Inc.Inventors: Nicholas A.

Patent number: 7389900Abstract: A wire guide, for a drive assembly of a wire feeding assembly, of a welding system, has an elongate body which has with an outer surface, a length, and first and second ends. An elongate bore extends along the length of, and through, the elongate body. An aperture extends through the elongate body, generally transverse to, and intersecting, the elongate bore. In some embodiments, the elongate body includes first and second body portions which can axially, laterally, and/or rotationally move with respect to each other. A generally arcuate recess can extend transversely into the outer surface of the elongate body, and can communicate with the aperture which extends through the elongate body, in a direction transverse to the elongate bore.Type: GrantFiled: March 1, 2005Date of Patent: June 24, 2008Assignee: Illinois Tool Works Inc.Inventor: Nicholas A.

Patent number: 7238918Abstract: A welding gun power pin for attaching a welding gun to a power block of a welding system. The welding gun power pin includes a generally cylindrical pin body, and insertion stop member, and a withdrawal stop member which defines a withdrawal stop member length dimension. A channel extends into the outer circumferential surface of the pin body, generally separates the pin body from the withdrawal stop member, and is adapted and configured to accept a generally rigid projection member therein, whereby to mechanically resist withdrawal of the welding gun power pin from the remainder of the welding system. The channel defines a channel width dimension which has a magnitude that is less than the magnitude of the withdrawal stop member length dimension.Type: GrantFiled: March 1, 2005Date of Patent: July 3, 2007Assignee: Illinois Tool Works Inc.Inventor: Nicholas A.
