K2652-4 - Lincoln Electric Magnum PRO 350 MIG Gun, 350A, 25 ft, PowerMIG Back End

Industrial-Grade Semiautomatic MIG Gun

The Lincoln Electric Magnum® PRO 350 (K2652-4) is a premium semiautomatic MIG welding gun engineered for high-performance industrial environments. Rated at 350 amperes with a 100% duty cycle when using CO2 shielding gas, this air-cooled gun is designed to withstand the rigors of continuous welding operations. The K2652-4 model features a 25-foot cable assembly, providing extensive reach for large fabrication projects without compromising wire feeding stability.

At the core of the Magnum PRO 350's performance is its industrial-grade construction. The gun utilizes high-quality copper and aircraft-grade aluminum components to ensure superior electrical contact and efficient heat dissipation. This robust design is critical for maintaining arc stability and preventing overheating during prolonged use. The gun is compatible with wire diameters ranging from 0.035 inches to 5/64 inches (0.9 mm to 2.0 mm), making it versatile for various MIG (GMAW), Pulsed MIG (GMAW-P), and Flux-Cored (FCAW) applications.

A key technological advantage of this series is the integration of Lincoln Electric's Copper Plus® Contact Tips. These tips feature a larger diameter and greater mass compared to standard contact tips, which significantly improves heat dissipation. This enhancement directly translates to extended tip life and reduced downtime for consumable changes. Additionally, the patent-pending Anti-Seize™ tip and diffuser thread design minimizes the risk of parts seizing in the gun tube, facilitating faster field service and maintenance.

The ergonomic design of the Magnum PRO 350 addresses operator comfort and fatigue. The Comfort Grip™ handle employs a barrel-style profile that is both lightweight and balanced, allowing for multiple hand positions. This design consideration is essential for welders working long shifts or in awkward positions. The Secure-Lock™ gun tube design further enhances reliability by resisting rotational slipping, ensuring that the gun remains rigid and predictable during operation. The K2652-4 is specifically configured with a back-end connection suitable for Lincoln Electric PowerMIG® series machines, ensuring seamless integration with compatible power sources.
