Patent number: 9770832Abstract: An adjustable cable fitting for a thru-arm cable of a robotic welding torch includes a female member formed of an elongated tubular body having a forward end, a rear end, and a through hole extending axially from the forward end to the rear end. The forward end includes a nose portion for connection to a welding cable. A male member is cooperable with the female member in a telescoping manner. The male member includes a shaft received in the through hole of the female member, a receiver connected to the shaft for receiving a power pin, and a through hole extending axially through the shaft and receiver. A nut is disposed on the shaft for locking a position of the shaft relative to the female member. Adjustment of a disposition of the male member relative to the female member varies an effective length of the power cable.Type: GrantFiled: March 27, 2015Date of Patent: September 26, 2017Assignee: Illinois Tool Works Inc.Inventors: Romeo N.

Patent number: 8963046Abstract: A self-adjusting liner assembly for a welding torch includes an elongated tubular body having a forward end, a rearward end, and a central bore extending from the forward end to the rearward end. An elongated fixed tube is mounted in the bore. The assembly further includes an elongated tubular slide having an inner end, an outer end, and a shoulder proximate the outer end. The fixed tube is received in the inner end of the slide, and the slide cooperates with the fixed tube in a telescoping relationship in the bore. A resilient member is disposed in the bore and envelopes a portion of the fixed tube and the slide. The resilient member engages the shoulder of the slide and urges the slide away from the fixed tube and toward the forward end of the body.Type: GrantFiled: June 6, 2011Date of Patent: February 24, 2015Assignee: Illinois Tool Works Inc.Inventors: Jeffrey G.
