OVERVIEW

Keep Your Arc Cool and Steady

Upgrade your welding operations with the Lincoln Electric KP2745-045 Copper Plus® Contact Tips, available in a convenient 10-pack. Designed for the serious welder who demands reliability, these tips are built to handle the heat. When you are pushing 550 amps and laying down heavy beads with .045 wire, standard tips can overheat, soften, and fail prematurely. Lincoln's Magnum® PRO line solves this problem with intelligent design features that keep you welding longer and troubleshooting less.

The Copper Plus Advantage

Heat is the enemy of any contact tip. As the tip heats up, the copper expands and softens, leading to poor electrical contact and wire drag. Lincoln's Copper Plus® technology combats this by increasing the diameter of the tip. This simple yet effective change puts more copper mass around the wire, creating a larger thermal reservoir to pull heat away from the bore. The result is a tip that stays cooler, maintains its shape, and delivers a consistent arc hour after hour. For you, this means less burnback, fewer erratic welds, and a significant reduction in consumable costs over time.

Frustration-Free Maintenance

We have all been there: you go to change a worn-out tip, and it is frozen solid in the diffuser. You grab the pliers, torque it, and end up stripping the threads or ruining the diffuser. The KP2745-045 features Anti-Seize™ threads designed to prevent exactly this scenario. The specialized thread profile resists fusing and seizing, ensuring that tip changes are quick, smooth, and tool-friendly. This small detail saves valuable time and prevents damage to your MIG gun's more expensive components.

Built for the Magnum PRO

These standard tips are the perfect match for your Lincoln Magnum® PRO MIG gun. They offer a balance of access and durability, making them suitable for a wide range of welding positions and joint configurations. By choosing genuine Lincoln Electric consumables, you ensure optimal conductivity and wire feeding performance. Don't let cheap consumables bottleneck your productivity; invest in Copper Plus® tips and experience the difference in arc quality and part life. This 10-pack ensures you are stocked up and ready to tackle the biggest jobs in the shop.
