KP2745-564R - Lincoln KP2745-564R Magnum PRO Copper Plus Contact Tip 5/64" 550A (10-Pack)

Stay Welding Longer with Copper Plus Technology

Every welder knows the frustration of a contact tip that burns back or seizes right in the middle of a critical pass. The Lincoln Electric KP2745-564R Magnum® PRO Contact Tip is built to solve exactly that problem. Designed for heavy-duty welding with 5/64-inch wire, this tip isn't just a replacement part; it's an upgrade for your torch. The "Extended Life" designation isn't just marketing—these tips are built to handle the heat. Thanks to Lincoln's Copper Plus™ technology, these tips feature a larger body with more copper, which acts like a heat sink to pull thermal energy away from the wire exit point. Cooler tips mean less spatter adhesion, less internal wear, and ultimately, a longer lifespan for each consumable.

Stop Fighting Seized Threads
One of the biggest time-killers on the shop floor is wrestling with a contact tip that has fused to the diffuser. The KP2745-564R features Lincoln's innovative Anti-Seize™ threads. This unique thread design prevents the metal from fusing together even after hours of welding at 550 amps. When it is finally time to change the tip, it spins off easily, letting you get back to the arc in seconds rather than minutes. This feature alone saves significant downtime and frustration over the course of a project.

Built for Performance
Whether you are running long structural welds or operating a robotic cell, consistency is key. These tips are machined from a durable Copper Chrome Zirconium alloy that resists wearing out, keeping your wire aimed exactly where you want it. Lincoln Electric estimates that these Extended Life tips can feed up to 20 lbs. more wire than standard tips before needing replacement. For high-volume shops, that adds up to serious savings in both parts and labor. This 10-pack ensures you have the premium consumables you need to keep your Magnum PRO gun running at peak performance.
