KP2745-040T - Lincoln Magnum PRO .040 Tapered Contact Tips 10-Pack

Stop Changing Tips, Start Welding

If you are tired of your contact tips melting, keyholing, or seizing up in the middle of a job, it is time to upgrade to the Lincoln Electric Magnum PRO series. The KP2745-040T is built for the serious welder running .040" wire who needs gear that can keep up with the heat. Rated for a massive 550 amps, these tips are designed to handle the punishment of spray transfer and high-deposition welding without failing prematurely. The tapered shape is a huge quality-of-life improvement, letting you see exactly where your wire is hitting the joint and allowing you to get your nozzle deeper into tight V-grooves or corners without obstruction.

The secret sauce here is Lincoln's Copper Plus™ technology. Standard copper tips get soft when they get hot, leading to the wire wandering and the hole wearing out into an oval (keyholing). These Magnum PRO tips use a special alloy that stays hard even when you are pushing the gun to its duty cycle limits. This means the arc stays focused, the wire feeds smoothly, and you aren't walking back to the tool crib every hour for a fresh tip. It’s about consistent performance; when the tip stays cool, the arc stays stable, and your spatter levels go down.

We also know the frustration of trying to unscrew a tip that has welded itself to the diffuser. You grab the pliers, you strip the threads, and suddenly you need a whole new front end. Lincoln solved this with their Anti-Seize™ thread design. The threads are engineered to dissipate heat and resist fusion, so when it is finally time to swap the tip, it spins out easily. This 10-pack ensures you have plenty of backup, but with the extended life of Copper Plus, you won't be burning through them nearly as fast as generic tips. Keep your arc on and your downtime off with Magnum PRO.
