Abstract
A jump liner for a push-pull MIG welding torch includes an elongated tubular body having front and back ends. The tubular body is made of a flexible plastic material. A front adapter is disposed at the front end of the tubular body. The front adapter is fittable in a retaining head of the torch. A back adapter is disposed at the back end of the tubular body. The back adapter is fittable in a gooseneck or body block of the welding torch. The front adapter provides sealing between the jump liner and the retaining head to prevent back flow leakage of shielding gas, and the front adapter prevents deformation of the tubular body at elevated temperatures. The back adapter provides sealing between the jump liner and the gooseneck or body block.
