KP2745-364AT-B100 - Lincoln Magnum PRO Contact Tip 3/64 Aluminum Tapered (100 Pack)

Reliable Feeding for Aluminum MIG Welding

Welding aluminum presents unique challenges, particularly with wire feeding and burnback. The Lincoln Electric Magnum® PRO KP2745-364AT contact tips are built to solve these problems. Unlike standard tips, these are specifically designed for 3/64" (1.2 mm) aluminum wire. Aluminum expands significantly as it heats up; if you use a standard steel tip, the wire can bind, causing erratic feeding or "birdnesting" at the drive rolls. These tips feature a slightly larger, optimized bore that allows the wire to expand freely while maintaining excellent electrical contact for a crisp, consistent arc.

Built to Last: Tired of constantly changing tips? These feature Lincoln's Copper Plus® technology. This proprietary alloy withstands the intense heat of the arc much better than standard copper, resisting the erosion that leads to an unstable arc. You get a tip that stays true longer, saving you trips to the tool crib and keeping your hood down. The anti-seize threads are a welder's best friend, ensuring that even after a long shift of high-amperage welding, the tip won't be fused to the diffuser when it's finally time to swap it out.

Better Visibility: The tapered design of these tips is a game-changer when you need to see the puddle in a tight joint. By narrowing the profile at the nozzle end, you get a clearer line of sight to your work and better gas coverage where it counts. Whether you are fabricating trailers, boats, or heat exchangers, these tips provide the reliability and precision professional welders demand. This 100-pack ensures your shop is stocked for the long haul.
