OVERVIEW

Smooth Aluminum Feeding with Miller 144855

Upgrade or repair your aluminum MIG setup with the Miller 144855 Teflon Liner. Welding aluminum requires specialized equipment to handle the softness of the wire, and the liner is one of the most critical components in the chain. This Teflon liner significantly reduces friction compared to standard steel liners, allowing the wire to glide smoothly through the gun cable. This reduction in drag is essential for preventing wire buckling and ensuring a stable, spatter-free arc.

Designed for wire sizes .045" through 1/16", this liner is perfect for structural aluminum work and other high-amperage applications. It measures approximately 12.6 feet in length, making it a direct replacement for liners in Miller XR series push-pull guns. Whether you are using an XR-Aluma-Pro or an XR-Pistol, this liner installs easily and restores the feeding performance of your gun to factory-new levels. Don't let a clogged or kinked liner ruin your welds; keep your equipment running at peak efficiency with this genuine Miller replacement.

Welders know that aluminum can be unforgiving. Using the correct liner material is the first step towards frustration-free welding. The Miller 144855 is built to withstand the rigors of daily use while protecting the integrity of your filler metal. Ensure your welds are clean and your wire feeds true with this essential maintenance part.

FAQ

This liner is designed for wire diameters ranging from 0.045 inches to 1/16 inches (0.062 inches).

It is made of Teflon (PTFE), which is ideal for reducing friction when feeding soft wires like aluminum.

The liner is 12.636 feet long, suitable for standard length push-pull guns.

While physically possible, Teflon liners are not recommended for steel wire as the hard wire can abrade the soft Teflon quickly. Steel liners are better suited for steel wire.

It is typically used with Miller XR-Aluma-Pro, XR-Pistol, and XR-Edge push-pull guns.

Aluminum wire is soft and easily deformed. A Teflon liner reduces drag and prevents the wire from shaving or buckling (bird-nesting) inside the cable.

Yes, this is a genuine Miller Electric replacement part, SKU 144855.

This product is typically sold as the liner conduit only. Check your gun's manual to see if additional retention hardware is needed.
