1. 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.
