KP2879-3 - Lincoln KP2879-3 Aluminum Neck Liner .035-1/16

Optimize Your Push-Pull Gun Performance

The Lincoln Electric KP2879-3 is a specialized plastic neck liner designed to facilitate the smooth feeding of soft welding wires, particularly aluminum. In push-pull welding systems, the neck liner—often called a jump liner—bridges the gap between the main conduit and the contact tip. This specific model is tailored for use with wire sizes from 0.035" up to 1/16", making it a versatile addition to your consumables inventory.

One of the primary issues in aluminum MIG welding is the generation of metal shavings and micro-scratches on the wire surface, which can lead to contact tip burn-back and erratic feeding. The KP2879-3 utilizes a durable polymer construction that eliminates metal-on-metal contact within the curved neck section of the gun. This is compatible with both 45-degree and 60-degree neck angles, ensuring a precise fit for Lincoln Electric Pistol Grip Push-Pull units. The plastic material also provides excellent insulation and durability under thermal stress.

Installation is straightforward, allowing operators to quickly swap out worn liners during routine maintenance intervals. Keeping a fresh neck liner installed is one of the most cost-effective ways to troubleshoot feeding issues in aluminum applications. Trust genuine Lincoln Electric parts to maintain the precision and durability of your welding system, ensuring consistent bead profile and penetration in every pass.
