KP2745-364A - Lincoln Magnum PRO 3/64 Aluminum Contact Tip 550A (10-Pack)

Reliable Aluminum Welding with Magnum® PRO Tips

If you are welding aluminum with a Lincoln Magnum® PRO MIG gun, the KP2745-364A contact tip is the consumable you need to keep your production line moving. Welding aluminum presents specific challenges, from wire softness to high heat input, and using the wrong contact tip can lead to constant burnbacks and frustration. This 10-pack of 3/64-inch contact tips is built to handle up to 550 Amps, giving you the durability required for serious fabrication work without constant replacements.

Built to Last Longer

Standard tips often overheat and wear out quickly when pushing aluminum at high amperages. Lincoln's Copper Plus™ tips are designed with a larger body and a special alloy that stays cooler, longer. By dissipating heat more efficiently, these tips maintain their shape and conductivity for extended periods. This means fewer interruptions for your welders and less money spent on daily consumables. The superior arc stability provided by these tips also results in cleaner welds with less spatter, reducing post-weld cleanup time.

No More Stuck Tips

We've all been there: you go to change a worn-out tip, and it's fused solid to the diffuser. You end up damaging the diffuser or wasting valuable time with pliers trying to wrench it free. The KP2745-364A features Anti-Seize™ threads that solve this problem. The unique thread design prevents the tip from locking up, ensuring that when it is time to swap it out, the old tip spins off easily and the new one seats perfectly every time. This feature alone can save significant frustration and maintenance time on the shop floor.

Genuine Lincoln Performance

When it comes to feeding aluminum wire, precision is key. These genuine Lincoln Electric OEM parts ensure that the bore size is perfectly matched to 3/64" wire, preventing the wandering arc and erratic feeding that come with generic replacements. Whether you are building trailers, boats, or industrial aluminum structures, trust the KP2745-364A to deliver consistent performance, arc start after arc start.
