KP2745-052-B100 - Lincoln Magnum PRO .052 Contact Tips, 550A Copper Plus (100-Pack)

Keep Your Gun Cool and Your Arc Smooth

Every welder knows the frustration of a contact tip that overheats, keyholes, or welds itself to the diffuser right in the middle of a job. The Lincoln Electric KP2745-052-B100 Magnum® PRO contact tip is built to solve exactly those problems. If you are running .052 wire—whether it's solid or flux-cored—you are likely pushing some serious amps. These tips are rated for 550A, meaning they are designed to handle the heat of heavy fabrication without softening or failing prematurely. The secret is the Copper Plus® design; these tips have a larger diameter and more copper mass than generic tips, acting like a heat sink to pull thermal energy away from the wire exit point.

The other major headache these tips eliminate is the "seized tip" scenario. We've all had to grab a pair of pliers—or worse, vice grips—to wrestle a fused tip out of a diffuser, sometimes ruining the diffuser threads in the process. Lincoln's Anti-Seize™ threading has a flattened thread profile that prevents the tip from locking up, even after you've been welding hot for hours. This means when it is finally time to swap the tip, it spins out easily, letting you get back to welding in seconds rather than minutes.

This 100-pack is ideal for busy shops running Magnum® PRO guns. With .052 wire being a standard for structural and heavy plate work, having a reliable supply of high-quality tips ensures your production line doesn't stop for lack of parts. The consistent bore diameter ensures good electrical contact for a stable arc, reducing spatter and burn-backs. Upgrade your front-end expendables to Magnum® PRO Copper Plus and experience the difference in tip life and ease of maintenance.
