Maximize Performance with Lincoln Magnum PRO Copper Plus Contact Tips

Upgrade your welding efficiency with the Lincoln Electric KP2744-045 Contact Tip, a key component in the Magnum® PRO consumable system. Designed for professional welders who demand reliability, these tips are built to handle the rigors of continuous MIG welding. The KP2744-045 is sized for .045-inch wire and is rated for 350 amps, making it an ideal choice for a wide range of medium to heavy-duty welding projects. This pack contains 10 contact tips, providing excellent value and ensuring you have replacements on hand when you need them most.

The Copper Plus® Advantage
Standard contact tips often fail prematurely due to overheating, leading to arc instability and burn-backs. Lincoln Electric addresses this with their Copper Plus® technology. By increasing the diameter of the tip and utilizing a specialized copper alloy, these tips possess a greater thermal capacity. This design draws heat away from the wire exit point more efficiently than conventional tips. The result is a contact tip that stays cooler, maintains its structural integrity longer, and provides a consistent electrical connection for a smoother, more controlled arc.

Designed for Durability and Ease of Use
Frustration with seized contact tips is a common issue in the shop. The KP2744-045 features Lincoln's Anti-Seize™ threading technology. The threads are engineered to resist fusing with the diffuser, even after prolonged exposure to high heat. This feature not only protects your MIG gun's diffuser but also simplifies maintenance, allowing you to swap out tips by hand without struggling with pliers or risking damage to the gun's front-end parts.

Compatibility and Application
These contact tips are specifically designed for the Magnum® PRO line of semi-automatic MIG guns, including the Magnum PRO 250L and 350 series. They are suitable for use with solid MIG wire as well as flux-cored wires requiring a .045" orifice. By choosing genuine Lincoln Electric consumables, you ensure perfect fitment and optimal performance of your welding equipment, reducing troubleshooting time and improving overall weld quality.
