KP2745-035T - Lincoln KP2745-035T Magnum PRO 550A Tapered Contact Tips .035 (10-Pk)

Reliable Tips for Smoother Welds and Less Downtime

For professional welders, few things are more frustrating than a contact tip that burns back, seizes in the diffuser, or wears out halfway through a critical job. The Lincoln Electric KP2745-035T Magnum PRO Contact Tip is built to solve these exact problems, giving you a reliable, long-lasting consumable that keeps you welding instead of troubleshooting. Designed for use with Lincoln's Magnum PRO MIG guns, these tips are rated for heavy-duty work up to 550 amps, making them ideal for structural steel, heavy equipment repair, and other demanding fabrication tasks. The "Tapered" design isn't just about looks; it helps you see what you're doing. By narrowing the tip near the arc, it gives you a better view of the puddle and lets you get into tighter corners without the nozzle getting in the way.

The real game-changer with these tips is the Copper Plus® technology. Standard copper tips get soft when they get hot, leading to the wire wearing out the hole into an oval shape (keyholing). When that happens, your arc starts wandering, and your welds get inconsistent. Lincoln's Copper Plus alloy is harder and handles heat much better, meaning the tip stays true longer. You get a stable, crisp arc for hours of welding, saving you trips to the supply cabinet. Plus, with a larger diameter mass than standard light-duty tips, it pulls heat away from the wire more effectively, preventing burn-backs that can ruin a good liner or gun neck.

Changing tips is also smoother thanks to the Anti-Seize™ threads. We've all had to grab a pair of pliers—or vise grips—to wrestle a stuck tip out of a hot gun, sometimes ruining the diffuser in the process. These tips are designed to screw in and out easily, even after getting blasted with heat and spatter. This 10-pack ensures you have plenty of spares on hand, though with the extended life of the Copper Plus alloy, you won't be burning through them as fast as generic tips. Whether you are running solid wire or flux-core, upgrading to genuine Magnum PRO tips is a small investment that pays off in less frustration and better weld quality at the end of the day.
