KP44N-116-15 - Lincoln Electric Magnum PRO Aluminum Liner 1/16-inch 15ft

Smooth Aluminum Welding with Magnum PRO

If you have ever wrestled with a birdnest of aluminum wire at the drive rolls, you know that the wrong liner can ruin your day. The Lincoln Electric KP44N-116-15 is the solution for welders running 1/16-inch aluminum wire through 15-foot leads. Unlike standard steel liners, which are often wound steel coils that can shave soft aluminum or cause excessive drag, this liner is designed specifically to let aluminum glide smoothly from the feeder to the contact tip. It is an essential upgrade for anyone setting up a Magnum PRO gun for aluminum projects.

This liner fits perfectly into Lincoln's Magnum PRO Semi-Auto guns and Robotic torches. The 15-foot length is standard for many shop setups, giving you the reach you need around large aluminum fabrications like boat hulls, trailers, or tanks. Installing the correct liner is the first step in troubleshooting erratic arcs or burn-back issues. When the wire feeds consistently, you get a stable arc, better puddle control, and cleaner starts and stops. This specific model is optimized for the larger 1/16-inch diameter wire often used in heavy-duty structural aluminum work, ensuring the internal diameter provides just the right amount of support without binding.

Maintenance is straightforward. When switching your rig from steel to aluminum, swapping out the liner prevents cross-contamination from iron filings that may be left in an old steel liner—contamination that can cause weld defects and corrosion issues later. The KP44N-116-15 is durable yet flexible, navigating the bends of your gun cable while maintaining a concentric path for the wire. Whether you are a professional fabricator or a serious hobbyist upgrading your Lincoln gear, this liner helps you achieve that stack-of-dimes look by taking the headache out of the wire feeding process.

Installation Tips:

• Ensure your gun cable is laid out straight before inserting the new liner.
• Check that the liner is fully seated in the diffuser/gas pin before trimming the back end.
• Always use a sharp cutting tool to ensure the liner end is clean and open, preventing drag at the entry or exit points.
