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.

Self-adjusting liner assembly for welding torch

A self-adjusting liner assembly for a welding torch includes an elongated tubular main body having forward and rearward ends. An elongated tubular retainer including a shoulder is mountable in the main body. An elongated tubular piston including a shoulder cooperates with the retainer in a telescoping relationship in the main body. A resilient member is disposed in the main body and envelops a portion of the retainer and the piston. The resilient member urges the shoulders away from each other and the tubular piston toward the forward end of the main body.

Self-adjusting liner assembly for a consumable electrode arc-welding torch

A robotic safety clutch that provides a wireless connection between the safety clutch and an robotic/automatic arm controller. The safety clutch includes a sensor for sensing a crash event and a radio frequency transmitter for transmitting a crash signal in response to the sensed crash event to a radio frequency receiver. The radio frequency receiver is connected to the robotic/automatic arm controller. Upon receiving the crash signal from the transmitter, the receiver sends a crash signal to the controller and in response to the crash signal, the controller shuts down all robotic/automatic functions.
