KP2745-040-B100 - Lincoln Electric Magnum PRO Copper Plus Contact Tip .040 in (100 Pack)

Maximize Uptime with Lincoln Electric Copper Plus Contact Tips

In high-volume industrial welding environments, consumable longevity and reliability are critical to maintaining production schedules. The Lincoln Electric KP2745-040-B100 Copper Plus Contact Tip (100 Pack) is engineered to address the common pain points of MIG welding: overheating and seized components. Designed specifically for the Magnum PRO series of MIG guns, these contact tips represent a significant upgrade in consumable technology, offering a robust solution for fabrication shops, heavy equipment manufacturing, and structural steel applications.

The defining feature of this series is the Copper Plus technology. By increasing the overall diameter of the contact tip, Lincoln Electric has effectively increased the copper mass available to absorb and disperse heat. In continuous welding operations running at high amperages—up to 550A—this thermal management capability is essential. Cooler running tips maintain their structural integrity longer, resist keyholing, and ensure consistent electrical conductivity. For procurement managers and shop foremen, this translates directly to reduced consumable spend and fewer interruptions for tip changes.

Furthermore, the KP2745-040-B100 features Lincoln's proprietary Anti-Seize threading. Traditional contact tips often fuse to the diffuser due to thermal expansion and micro-arcing, leading to damaged gun front-ends and frustrated operators. The Anti-Seize thread profile is flattened to reduce surface contact area in the threads while maintaining a secure mechanical connection. This design prevents the tip from melting or seizing into the gas diffuser, ensuring that when a change is finally necessary, it can be performed quickly and without tools. Supplied in a bulk pack of 100, these tips ensure your inventory is stocked for long-term operational stability.
