KP2745-116R - Lincoln Electric Magnum PRO Copper Plus Contact Tip 1/16" 550A (10-Pack)

Reliable Arc Performance for Professional Welders

Upgrade your Magnum® PRO MIG gun with the Lincoln Electric KP2745-116R Copper Plus® Contact Tip, designed to keep you welding longer with fewer interruptions. Every welder knows the frustration of a contact tip that overheats, keyholes, or fuses to the diffuser right in the middle of a job. Lincoln Electric has solved these issues with the Copper Plus design. By using a larger diameter body and high-grade Copper Chrome Zirconium material, these tips stay cooler even when running at high amperages up to 550A. A cooler tip means the wire feeds more smoothly, the arc stays stable, and you spend less time walking back to the tool crib for replacements.

One of the standout features for daily users is the Anti-Seize™ threading. Traditional tips often expand and lock into the diffuser after a long day of welding, requiring pliers or vice grips to remove—often damaging the diffuser in the process. The KP2745-116R uses a special thread design that prevents this thermal locking, allowing for easy, consistent change-outs every time. This 1/16-inch (1.6 mm) tip is built for precision; the tighter internal diameter ensures the wire makes solid electrical contact exactly where it should, reducing micro-arcing inside the tip and improving your overall weld bead appearance.

Whether you are welding heavy structural steel or running long beads in a manufacturing setting, these Extended Life tips deliver superior durability. They are designed to handle the heat and physical wear of heavy wire feeding, lasting significantly longer than standard copper tips. This pack of 10 ensures you have plenty of backup on hand, though with the extended life of each tip, you won't need to restock as often.
