KP2745-040R - Lincoln Magnum PRO 550A Contact Tip 0.040 Copper Plus (10-Pack)

Maximize Uptime with Lincoln Electric Magnum PRO Copper Plus Contact Tips

For professional welders seeking reliability and longevity in their MIG welding consumables, the Lincoln Electric KP2745-040R Magnum PRO Copper Plus Contact Tip is an industry-leading solution. Designed to handle the rigors of high-amperage industrial environments, these contact tips are rated for up to 550A, making them ideal for heavy fabrication and continuous welding cycles. The pack contains 10 precision-engineered tips tailored for 0.040 inch (1.0 mm) wire.

The secret to the performance of the KP2745-040R lies in Lincoln Electric's proprietary Copper Plus® technology. Unlike standard copper tips, Copper Plus tips feature a larger diameter-to-mass ratio. This design enhancement significantly improves the tip's ability to dissipate heat generated at the contact point. By keeping the tip cooler, the alloy maintains its hardness longer, resists keyholing, and prevents the wire from fusing to the tip (burn-back). This translates directly to reduced downtime for consumable changes and lower overall operating costs for your shop.

These contact tips are an integral part of the Magnum PRO expendables system. They are engineered to seat perfectly within Magnum PRO gas diffusers, ensuring optimal electrical conductivity and gas coverage. Whether you are welding mild steel, stainless steel, or aluminum, consistent electrical transfer is critical for a stable arc. The KP2745-040R delivers that consistency, helping you achieve defect-free welds with less spatter. Stock up on this 10-pack to ensure your welding stations remain productive and efficient.
