KP2745-072 - Lincoln Magnum PRO Copper Plus Contact Tip .072 (10-Pack)

Lincoln Electric Magnum PRO Copper Plus Contact Tips (.072)

Experience the difference that superior engineering makes with the Lincoln Electric KP2745-072 Copper Plus Contact Tip. Part of the renowned Magnum PRO consumable line, this tip is designed to solve the common pain points associated with high-amperage MIG welding. The core innovation lies in the Copper Plus design. By increasing the diameter of the tip, Lincoln Electric has packed more copper into the consumable. This increased volume improves thermal conductivity, allowing the tip to dissipate heat much faster than standard designs. The result is a contact tip that stays cooler, lasts longer, and maintains a stable arc even under the rigorous demands of 550A welding procedures.

This specific contact tip is sized for .068 to .072 inch (1.7-1.8 mm) wire, making it a staple for heavy fabrication tasks. Beyond thermal management, the KP2745-072 features Lincoln's patented Anti-Seize thread technology. The threads are engineered with a flattened profile that serves a dual purpose: it maximizes the contact area for efficient current transfer and prevents the tip from fusing to the gas diffuser. This ensures that when it is finally time to replace the tip, it unthreads easily without the need for excessive force or tools that could damage your MIG gun.

Welders Supply Company recommends the KP2745-072 for professionals who demand consistency and longevity from their equipment. Frequent tip changes drain productivity and increase operational costs. By switching to Magnum PRO Copper Plus tips, you invest in consumables that work as hard as you do. These tips are compatible with all Magnum PRO MIG guns and are an essential upgrade for any welder looking to optimize their setup for high-heat, high-deposition welding. Each package contains 10 contact tips, providing excellent value and ensuring you are prepared for the job ahead.
