14501153 - Tweco 45-116-15 MIG Gun Liner for 1/16" Wire, 15 ft

Smooth Feeding for 1/16" Wire

If you are experiencing erratic wire feeding, sputtering arcs, or the dreaded "birdnest" at your drive rolls, your liner is often the culprit. The Tweco 45-116-15 Standard Conduit Liner is the direct replacement you need to get your 15-foot MIG gun running like new again. Designed specifically for heavier 1/16-inch (1.6mm) wire, this liner provides the correct internal clearance to support the wire without allowing it to buckle or wander, which is critical when pushing wire over 15 feet.

Over time, MIG liners become clogged with dirt, shop dust, and metal shavings from the welding wire itself. This debris increases friction, causing your wire feeder to work harder and leading to an unstable arc that frustrates even the most experienced welder. Installing a fresh Tweco 45-116-15 liner eliminates this friction. The zinc-plated steel construction is durable and smooth, allowing the wire to glide effortlessly from the machine to the puddle. This is the standard "wound" steel liner, perfect for running mild steel solid wire or flux-cored wire in structural and heavy fabrication jobs.

Installation is straightforward. The liner comes ready to install in standard Tweco guns compatible with the 45 Series. Simply remove the old liner, slide the new one in, and trim the excess at the front end according to your gun's specific stick-out requirements. Don't let a cheap or worn-out liner ruin your welds. By maintaining your equipment with genuine Tweco parts, you ensure consistent penetration, better bead appearance, and less downtime fixing feed issues.
