14501114 - Tweco WS45116-15 WeldSkill MIG Liner .045-1/16 15ft

Smooth Feeding for Superior Welds with Tweco WeldSkill

Every welder knows that a bad liner can ruin a good day. If your wire is stuttering, dragging, or burning back to the tip, it might be time to replace your conduit. The Tweco WeldSkill WS45116-15 (Part # 1450-1114) is the reliable solution for welders running .045" to 1/16" wire in 15-foot MIG guns. Don't let friction fight your feed motor; this liner is built to let your wire glide smoothly right to the puddle, ensuring you get that consistent frying-bacon sound we all look for.

Built tough for the shop environment, this liner features a zinc-plated steel construction. Why does that matter? Because moisture and humidity in your shop can rust a bare steel liner before you even install it. The zinc coating protects the liner from corrosion, ensuring that the inside remains smooth and clean. This reduces the friction coefficient against your welding wire, which is especially important when pushing softer or flux-cored wires over a 15-foot distance. A smooth feed means a stable arc, less spatter, and better bead appearance.

Installation is straightforward. The liner comes ready to install in your Tweco WeldSkill gun. Simply remove the old liner, slide this new one in, and trim it to the correct length at the front end. It's designed to support a range of wires, giving you the flexibility to switch between .045 solid wire and 1/16 flux-core without necessarily changing your liner every time (though keeping it clean is always recommended). Whether you are fabricating structural steel, repairing heavy equipment, or working on general manufacturing, this liner is the backbone of your wire delivery system.

Don't compromise on your consumables. Using genuine Tweco parts like the WS45116-15 ensures that your equipment lasts longer and performs better. A fresh liner is one of the cheapest ways to fix a "bad welder." If you are experiencing feeding issues, check your liner first, and replace it with this high-quality conduit to get back to laying down perfect beads.
