Abstract
An example wire liner retention apparatus includes: a body comprising a bore extending longitudinally through the body, the bore configured to permit passage of a welding wire liner through the bore; a clamp configured to apply a compressive force to the welding wire liner in a radial direction within the bore to limit movement of the welding wire liner with respect to the body; and a compression adjustment mechanism configured to adjust the compressive force applied by the clamp.
Claims16
A wire liner retention apparatus, comprising:
- a body comprising a bore extending longitudinally through the body, the bore configured to permit passage of a welding wire liner through the bore;
- a clamp configured to apply a compressive force to the welding wire liner in a radial direction within the bore to limit movement of the welding wire liner with respect to the body, wherein the clamp comprises a first jaw and a second jaw arranged on opposing sides of the welding wire liner, and the compression adjustment mechanism is configured to urge the first jaw toward the second jaw to increase the compressive force applied by the clamp;
- and
- a compression adjustment mechanism configured to adjust the compressive force applied by the clamp, wherein the compression adjustment mechanism comprises a set screw configured to control the compressive force applied to the welding wire liner by the first jaw and the second jaw.

A welding torch, comprising:
- a contact tip assembly configured to conduct welding power to a welding wire;
- a welding cable configured to conduct the welding power to the contact tip assembly;
- a power pin configured to couple the welding cable to a welding-type power supply;
- and
- a wire liner retention device configured to limit movement of a welding wire liner relative to the power pin, the wire liner retention device comprising:
- a body comprising a bore extending longitudinally through the body, the bore configured to permit passage of the welding wire liner through the bore;
- a clamp configured to apply a compressive force to the welding wire liner in a radial direction within the bore to limit movement of the welding wire liner with respect to the body, wherein the clamp comprises a first jaw and a second jaw arranged on opposing sides of the welding wire liner, and the compression adjustment mechanism is configured to urge the first jaw toward the second jaw to increase the compressive force applied by the clamp;
- and
- a compression adjustment mechanism configured to adjust the compressive force applied by the clamp, wherein the compression adjustment mechanism comprises a set screw configured to control the compressive force applied to the welding wire liner by the first jaw and the second jaw.
