KP2745-764 - Lincoln Electric KP2745-764 Magnum PRO Copper Plus Contact Tip 550A 7/64" (10-Pack)

Premium Lincoln Electric Consumables for Industrial Welding

The Lincoln Electric KP2745-764 is a high-performance contact tip designed for the rigorous demands of heavy industrial fabrication. Part of the Magnum® PRO series, this consumable is engineered to handle high amperages up to 550A, making it an essential component for structural steel, heavy equipment manufacturing, and other intensive welding environments. This specific tip is sized for 7/64 inch (2.8 mm) wire, a gauge typically reserved for high-deposition applications where consistent electrical contact and thermal management are critical for weld quality.

At the core of this product's performance is Lincoln's proprietary Copper Plus® technology. Unlike standard contact tips, Copper Plus® tips feature a larger outer diameter and a greater overall mass of copper alloy. This design enhancement is not merely cosmetic; it significantly increases the thermal capacity of the tip. By providing a larger heat sink, the tip disperses arc heat more effectively, keeping the operating temperature lower. A cooler tip maintains its structural integrity longer, resists keyholing (the wearing of the bore into an oval shape), and ensures consistent arc targeting over extended periods of welding.

Another standout feature for maintenance and operations teams is the Anti-Seize™ threading. In high-heat applications, standard tips often fuse to the gas diffuser, leading to costly downtime and potential damage to the gun's front-end parts during removal. The KP2745-764 utilizes a specialized thread profile that flattens the thread peaks, increasing the surface area for heat transfer while simultaneously preventing the materials from seizing together. This ensures that when it is finally time to replace the tip, the changeover is quick, tool-free, and frustration-free.

Supplied in a package of 10, these contact tips offer excellent value and inventory control for busy shops. By investing in genuine Lincoln Electric Magnum® PRO consumables, users ensure optimal compatibility with their equipment and maintain the high standards of arc performance expected from the brand.
