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

Optimize Your Aluminum MIG Gun with Miller M1441

Achieving the perfect aluminum weld requires more than just a good power source; it demands a flawless wire delivery system. The Miller M1441 Teflon Liner is a premium replacement part designed for the neck assembly of Miller Push-Pull MIG guns utilizing Centerfire consumables. This 4-inch liner segment is crafted from high-grade Teflon, a material chosen for its exceptional lubricity and heat resistance. It is specifically sized to accommodate .030-inch to .035-inch aluminum wire, providing the gentle support needed to prevent wire deformation during feeding.

Standard steel liners can scratch and snag soft aluminum wire, leading to micro-shavings that clog the liner and contact tip. The M1441 eliminates this issue by providing a smooth, non-abrasive conduit through the gooseneck of the gun. This is particularly important in Push-Pull systems where the wire is being synchronized between the feeder and the gun motor. A compromised neck liner can cause synchronization errors, burn-backs, and erratic arc starts. By installing a fresh M1441 liner, welders can restore the factory-spec performance of their equipment and ensure trouble-free operation.
