KP45-3545-15 - Lincoln Electric KP45-3545-15 Magnum PRO Liner .035-.045 15ft

Restore Smooth Performance to Your Magnum PRO Gun

Is your wire feeding erratically? Are you experiencing arc instability or excessive burn-back? It might be time to replace your gun liner. The Lincoln Electric KP45-3545-15 Cable Liner is the genuine OEM replacement part you need to get your Magnum® PRO MIG gun back to peak performance. Designed for 15-foot cable assemblies, this liner is compatible with both Semi-Automatic and Robotic Magnum PRO torches, making it a versatile addition to your welding toolkit.

A worn or dirty liner is one of the most common causes of frustration for welders. As wire travels through the gun, it can shave off small particles of copper and pick up shop dust, which eventually clogs the liner and increases friction. This friction causes the wire to slip at the drive rolls or surge at the tip, leading to sloppy welds. Installing a fresh KP45-3545-15 liner restores the smooth, consistent feed you expect from Lincoln Electric equipment. This liner is specifically calibrated for .035" to .045" (0.9-1.2 mm) wire, ensuring the internal clearance is tight enough to support the wire but loose enough to allow free movement.

Installation is straightforward, allowing you to get back under the hood quickly. Simply remove the old liner, unroll the new one, and slide it into the gun cable. Because it is a genuine Lincoln part, you don't have to worry about fitment issues or inferior materials that wear out prematurely. The high-quality steel winding provides excellent flexibility without collapsing, even when the gun cable is bent during out-of-position welding.

Don't let a cheap or worn-out liner ruin your welds. The liner is the highway your welding wire travels on; keep it paved and smooth with the Lincoln KP45-3545-15. Whether you are welding mild steel in a garage or running production beads in a fabrication shop, this liner delivers the consistency required for professional results. Keep a spare in your toolbox so you are never caught off guard by feeding problems in the middle of a job.
