KP2010-1 - Lincoln Electric Teflon Liner for Magnum SG Spool Guns

Optimized Feeding for Aluminum Welding

The Lincoln Electric KP2010-1 Teflon Liner is a critical component for welders working with aluminum. Unlike standard steel liners, which can cause friction and shaving on soft wires, this liner is manufactured from high-quality Teflon. This material significantly reduces drag, allowing aluminum wire to slide smoothly through the gun cable. This is essential for preventing "bird-nesting"—the tangling of wire at the drive rolls—which is a common frustration in aluminum MIG welding.

Designed specifically for the Magnum SG Spool Series and compatible with the Magnum 250 XL, this liner ensures that your equipment operates at peak efficiency. Whether you are fabricating boat hulls, repairing automotive components, or performing general aluminum maintenance, consistent wire delivery is key to a stable arc and a clean bead. The KP2010-1 provides that consistency, reducing downtime caused by feed issues and equipment jams.

As a genuine Lincoln Electric part, this liner guarantees a perfect fit within the specified gun assemblies. Installation is straightforward, allowing you to swap out worn or contaminated liners quickly and get back to work. By using the correct liner for your wire type, you extend the life of your consumables and improve the overall quality of your welding projects.
