KP1958-4 - Lincoln Electric KP1958-4 Red Aluminum MIG Liner, 1/16 in, 15 ft

Smooth Feeding for Aluminum Projects

Struggling with aluminum wire feeding issues? The Lincoln Electric KP1958-4 Red Aluminum Liner is designed to solve the headaches associated with MIG welding aluminum. If you have ever experienced the frustration of your wire burn-backing or bird-nesting at the drive rolls, you know that the wrong liner is often the culprit. This liner is specifically crafted for 1/16-inch (1.6 mm) aluminum wire, providing a smooth, low-friction path that allows the soft wire to glide easily through the cable, even at a length of 15 feet.

The distinct red color makes it easy to identify in your shop, ensuring you don't accidentally try to run steel wire through it or use it for the wrong wire size. When welding aluminum, friction is the enemy. This liner minimizes drag, which helps your wire feeder push the wire consistently without slipping or deforming. This consistency translates directly to your arc stability, giving you cleaner beads and better penetration without the constant interruptions of clearing a jammed gun.

Installation is straightforward for welders familiar with Lincoln MIG guns. Simply remove the old liner, unroll the KP1958-4, and slide it into the gun cable assembly. Trimming may be required to get the perfect fit for your specific gun setup, ensuring the liner seats perfectly against the diffuser or contact tip. Whether you are fabricating boat hulls, repairing trailers, or working on custom aluminum parts, trusting a genuine Lincoln liner ensures your equipment performs at its best, letting you focus on the puddle rather than the feeder.
