KP2745-040 - Lincoln Electric KP2745-040 Magnum PRO Copper Plus Contact Tip .040 (10-Pack)

Extend Your Consumable Life with Lincoln Copper Plus

Upgrade your welding experience with the Lincoln Electric KP2745-040 Contact Tip, designed to keep you welding longer and changing parts less often. If you use a Magnum PRO MIG gun, these tips are the ultimate upgrade for your setup. The "Copper Plus" designation isn't just a name—it refers to the increased copper content and larger mass of the tip itself. This extra material acts as a heat sink, pulling thermal energy away from the intense heat of the arc. The result? A contact tip that stays cooler, resists wear, and maintains its shape far longer than standard competitors.

For welders running .040" (1.0 mm) wire, precision is key. A worn tip causes the wire to wander, leading to a wandering arc and poor bead placement. The KP2745-040 is machined to exacting tolerances to ensure the wire feeds smoothly while maintaining the electrical contact necessary for a crisp, consistent arc. Rated for up to 550 amps, this tip can handle the heat of spray transfer and high-deposition welding without breaking a sweat.

Say Goodbye to Seized Tips

We've all been there: you try to unscrew a worn contact tip, and it's completely frozen in the diffuser. You end up using pliers, ruining the threads, or even damaging the gas diffuser. Lincoln Electric's Anti-Seize thread technology solves this problem for good. The unique thread design prevents the tip from fusing to the gun, ensuring that when it is finally time to swap out the tip, it spins off freely. This feature alone saves time and frustration on the shop floor, allowing you to get back under the hood faster.

This 10-pack ensures you have plenty of spares on hand, though with the extended life of Copper Plus technology, you'll find yourself reaching for a new one much less frequently. Invest in genuine Lincoln Electric consumables to get the best performance out of your Magnum PRO equipment.
