Abstract
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.
