M1114 - Miller M1114 15ft MIG Gun Liner Assembly

Keep Your Arc Smooth with the Miller M1114 Liner

Is your MIG gun sputtering, stuttering, or fighting you every inch of the weld? Before you blame the machine or the wire, check your liner. The Miller M1114 Conduit/Liner Assembly is the genuine replacement part you need to get your 15-foot Miller MIG gun back to running like new. The liner is the unsung hero of your welding setup—it's the highway your wire travels down. When that highway gets potholed with rust, clogged with dirt, or kinked from heavy use, your weld quality suffers immediately. Don't let a cheap or worn-out liner ruin your bead profile or cause frustrating burn-back issues.

Designed specifically for Miller equipment, this 15-foot liner assembly offers the perfect fit and feed characteristics for your gun. Unlike generic aftermarket liners that might have inconsistent internal diameters or rough coils, the M1114 is built to reduce drag. Less drag means your wire feeder doesn't have to work as hard, and the wire comes out of the tip at a constant, predictable speed. This consistency is the key to that "frying bacon" sound every welder loves to hear. Whether you are welding mild steel, stainless, or flux-cored applications, ensuring your wire path is clean and smooth is step one in troubleshooting any feed problem.

Installation is standard for Miller guns. Simply remove the old liner, unroll the new M1114, and slide it in. Because it is a 15-foot assembly, it is designed for standard 15-foot leads, but as with all liner replacements, be sure to follow the manufacturer's instructions for trimming the stick-out at the front end to ensure perfect contact with the diffuser. A fresh liner is one of the cheapest insurance policies you can buy for your weld quality. If you are experiencing bird-nesting at the drive rolls or the wire feels like it's surging, it's time to swap it out.

Don't wait until your gun completely jams in the middle of a critical job. Professional welders know that consumables like liners are wear items that need regular changing. By choosing the genuine Miller M1114, you are choosing reliability and performance. Keep a spare in your toolbox or shop cabinet so you are never caught off guard.
