KP45-18-15 - Lincoln Electric Magnum PRO Cable Liner for 7/64-1/8 Wire, 15 ft

Smooth Feeding for Heavy-Duty Welding

When you are running heavy wire—we're talking 7/64 to 1/8 inch—you know that feed problems can shut down production in a heartbeat. The Lincoln Electric KP45-18-15 Cable Liner is built to handle the heavy lifting. Designed specifically for your 15-foot Magnum® PRO MIG guns, this liner provides the rugged support needed to push thick wire through the cable without binding, chattering, or dragging. Whether you are welding structural steel, heavy equipment, or running a robotic cell, this liner ensures your wire gets to the puddle exactly when and how it's supposed to.

A worn-out liner is the number one cause of erratic feeding and burn-back. If you are noticing your arc starting to stutter or your wire pile-up at the feeder, it’s time to swap it out. This genuine Lincoln replacement is made from high-quality steel wound to precise tolerances. It supports the wire firmly to prevent buckling inside the cable, which is especially critical when pushing soft cored wires or stiff solid wires over a 15-foot distance. The smooth interior surface minimizes friction, extending the life of your drive rolls and reducing the strain on your wire feeder motor.

Don't settle for generic knock-offs that might not fit your Magnum PRO gun correctly. The KP45-18-15 is designed to seat perfectly in the back of the gun and trim easily at the front, ensuring optimal gas flow and electrical conductivity. Keep a spare in your tool crib or maintenance cart. Swapping out an old, clogged liner for a fresh KP45-18-15 is one of the cheapest and fastest ways to instantly improve your weld quality and reduce frustration on the shop floor.
