M1461 - Miller M1461 Phosphor Bronze Jump Liner for Fastip Systems

Smooth Feeding for Aluminum Welding

Every welder knows the frustration of bird-nesting and erratic wire feeding when working with aluminum. The Miller M1461 Phosphor Bronze Liner is your solution to these common headaches. Designed specifically as a jump liner for the neck of your MIG gun, this 4-inch component replaces the standard steel coil in the curved section of the torch, providing a smooth, low-friction path for your wire right where it needs it most. If you are running a Fastip system and struggling with soft wires, this is the upgrade you need.

Why Phosphor Bronze?
Unlike standard steel liners, phosphor bronze is softer and slicker. When you are pushing soft aluminum or bronze wire through a steel liner, the microscopic rough edges of the steel can shave off tiny flakes of the wire. These shavings build up inside the liner, clogging the path and causing the wire to drag, stutter, or jam completely. The M1461 eliminates this issue in the most critical part of the gun—the bend. By installing this jump liner, you ensure that the wire glides effortlessly into the contact tip, resulting in a stable arc and better-looking welds.

Easy Maintenance and Compatibility
This liner is designed for wires ranging from .030" to 1/16", covering the most common sizes for light to medium-duty aluminum fabrication. It is a direct replacement part for Miller and Bernard Fastip setups. Replacing your jump liner regularly is a small maintenance step that pays off in huge productivity gains. Don't let feed problems ruin your workflow; equip your torch with the M1461 and experience the difference a dedicated aluminum liner makes.
