75015229T - American Weldquip 15ft Liner 5/64-3/32 for 300-500A MIG Guns

Restore Smooth Feeding for Heavy Fabrication

When you are welding with heavy wire, every component in your MIG gun needs to be tough, but the liner is the unsung hero of your setup. The American Weldquip 75015229T Liner Assembly is built to handle the grueling demands of pushing 5/64" and 3/32" wire through a 15-foot cable. If you have noticed your wire stuttering, your arc wandering, or your feeder motor straining, a worn or clogged liner is often the culprit. This genuine OEM replacement restores the "like-new" performance of your American Weldquip 300A, 400A, or 500A MIG gun, ensuring that your wire glides smoothly from the machine to the puddle without interruption.

Heavy industrial welding—whether it's structural steel, heavy equipment repair, or tank fabrication—relies on consistency. Using a liner specifically designed for large diameter wires (5/64" - 3/32") is crucial. A standard liner simply can't handle the stiffness and weight of these wires, leading to rapid wear and feeding issues. The 75015229T is crafted from durable, high-quality steel wound to precise specifications. This construction provides the flexibility you need to maneuver around the shop floor while maintaining a rigid internal channel that prevents the wire from buckling inside the cable. The 15-foot length is perfectly sized for standard long-reach guns, giving you the freedom to work on large assemblies without moving your power source constantly.

Don't let a cheap or worn-out liner compromise your weld quality. Friction inside the liner can cause micro-vibrations in the wire as it exits the contact tip, leading to an unstable arc and excessive spatter. By installing this genuine American Weldquip liner, you ensure optimal electrical contact and mechanical stability. It is an easy, cost-effective fix that pays for itself by reducing downtime and frustration. Whether you are running flux-cored or solid wire, this liner assembly is the reliable conduit your heavy-duty projects demand. Keep a spare in your toolbox so you are never caught off guard by a feeding problem in the middle of a critical job.
