M1441 - Miller M1441 Teflon Jump Liner for .030-.035 Aluminum Wire

Precision Aluminum Feeding with Miller M1441

The Miller M1441 Liner is a specialized consumable designed to address the unique challenges of welding with aluminum wire. Unlike steel wire, aluminum is soft and prone to buckling, kinking, or shaving when pushed through standard steel liners. This product is a Teflon neck liner (often called a jump liner) specifically engineered for the head tubes of Push-Pull (PP) MIG guns equipped with the Centerfire consumable system. Its low-friction composition ensures that .030" to .035" aluminum wire glides smoothly through the final bend of the torch, delivering a stable arc and consistent weld bead.

In industrial fabrication environments where aluminum is a primary material, equipment downtime due to "bird-nesting" or erratic feeding can be costly. The M1441 serves as the final bridge in the wire feeding path, protecting the soft wire right up to the contact tip. At 4 inches in length, it is perfectly sized for standard 4-inch gun necks found on Miller XR-Aluma-Pro and similar push-pull systems. Regular replacement of this liner is essential for maintaining high-quality aluminum welds, as worn liners can accumulate aluminum oxide shavings that increase friction and degrade performance.

Key Applications

• Aluminum Fabrication: Essential for boat building, trailer manufacturing, and aerospace components where aluminum wire is used.


• Push-Pull Systems: Designed to fit the specific geometry of Miller push-pull gun necks.


• Fine Wire Welding: Optimized for smaller diameter wires (.030-.035) often used on thin-gauge aluminum sheet.
