KP2744-116A - Lincoln Electric KP2744-116A Magnum PRO Copper Plus Contact Tip for Aluminum Wire, 1/16 in - 10 Pack

Smoother Arc, Less Burnback for Aluminum

If you have ever struggled with aluminum MIG welding, you know the frustration of burnback, birdnesting, and erratic arcs. The Lincoln Electric KP2744-116A Magnum® PRO Contact Tip is built to solve these specific headaches. Designed specifically for running 1/16" (1.6 mm) aluminum wire, this tip isn't just a standard copper tube; it is a performance upgrade for your Magnum PRO gun. The secret lies in the Copper Plus® design. These tips are physically larger and heavier than standard tips, packing more copper into the consumable. This extra mass acts as a massive heat sink, pulling heat away from the wire exit point. A cooler tip means less chance of the wire fusing to the tip (burnback) and a more consistent arc start every time you pull the trigger.

Aluminum wire expands significantly as it heats up, much more than steel. If you use a standard steel tip for aluminum, the wire can bind as it gets hot, leading to feeding issues and the dreaded birdnest at the drive rolls. The KP2744-116A is bored specifically to handle 1/16" aluminum, providing the perfect balance of electrical contact and clearance for smooth feeding. This results in a stable, crisp arc that lays down professional beads with less spatter and better fusion.

Another feature welders will appreciate is the Anti-Seize™ threading. We've all been there—trying to wrench off a fused contact tip that has practically welded itself to the diffuser. Lincoln's unique thread design prevents this seizing, so when it is finally time to swap tips, it spins off easily. Whether you are fabricating boat hulls, trailers, or custom aluminum parts, these tips give you the reliability you need to focus on the puddle, not the gun. Sold in a convenient 10-pack, you can keep your toolbox stocked and your downtime low.
