KP2745-364A-B100 - Lincoln Magnum PRO 550A Aluminum Contact Tip 3/64 - 100 Pack

Maximize Uptime with Magnum® PRO Copper Plus® Contact Tips

Welding aluminum is challenging enough without having to worry about your contact tip failing halfway through a critical pass. The Lincoln Electric KP2745-364A-B100 Magnum® PRO contact tips are your solution for reliable, high-performance aluminum welding. Sold in a convenient, cost-effective pack of 100, these tips are designed to keep your production line moving and your welders welding, rather than constantly swapping out burnt consumables. If you are running 3/64-inch (1.2 mm) aluminum wire, you need a tip that can handle the heat and the specific feeding characteristics of soft alloys.

What sets these tips apart is the Copper Plus® technology. Standard copper tips wear out quickly, especially at high amperages like 550A. As the tip wears, the hole becomes oval-shaped, leading to erratic arc wandering and poor weld quality. Lincoln's Copper Plus® alloy is harder and dissipates heat much faster, meaning the tip stays true longer. For aluminum welders, this is a game-changer. The specific bore size allows for the natural expansion of hot aluminum wire without seizing, preventing the dreaded "birdnesting" at the drive rolls caused by tip friction.

These tips are compatible with the industry-leading Magnum® PRO series MIG guns, known for their durability and comfort. By upgrading to Copper Plus® tips, you aren't just buying a consumable; you are investing in arc stability. A stable arc means less spatter, better penetration, and cleaner welds that require less post-weld cleanup. Whether you are fabricating trailers, boat hulls, or heavy industrial aluminum structures, this 100-pack ensures you have the premium supplies needed to maintain peak efficiency shift after shift.
