KP44N-3545-15 - Magnum PRO Aluminum Liner .035-3/64 15ft

Smooth Aluminum Welding Starts with the Right Liner

If you have ever wrestled with aluminum wire bird-nesting at the feeder or burning back to the tip, you know that the liner is often the culprit. The Lincoln Electric KP44N-3545-15 is your solution for frustration-free aluminum welding with Magnum PRO guns. Designed specifically for soft wires like 4043 and 5356 in the .035 to 3/64 inch range, this 15-foot liner reduces the friction that kills your feed speed and ruins your welds. It acts as a smooth highway for your wire, ensuring it gets from the spool to the puddle without snagging or shaving.

Swapping out your liner is one of the cheapest and most effective ways to improve your aluminum welding performance. This genuine Lincoln liner is built to fit perfectly into your Magnum PRO Semi-Auto or Robotic torch, eliminating the guesswork of universal parts. The material is selected to let aluminum slide easily, preventing the drag that causes erratic arcs and spatter. Whether you are fabricating boat hulls, repairing trailers, or running a production line, consistent wire feeding is non-negotiable.

Don't let a worn-out or incorrect liner slow you down. Using a steel liner for aluminum is a recipe for disaster; the rough internal surface will shave the soft wire, clogging the path and stopping your work cold. Upgrade to the KP44N-3545-15 to keep your operation running smoothly. It is durable, easy to install, and engineered by the same people who built your welder, guaranteeing the performance you expect from the Lincoln Electric brand.
