K2653-2-10-45 - Magnum PRO 450 Semi-Automatic MIG Gun 15ft Ready-Pak

Industrial Grade Performance for High-Amperage Applications

The Lincoln Electric Magnum® PRO 450 Welding Gun Ready-Pak (K2653-2-10-45) is engineered to meet the rigorous demands of heavy industry. Designed for semi-automatic MIG, pulsed MIG, and flux-cored welding, this 15-foot air-cooled gun delivers a robust 450A output at 100% duty cycle when using CO2 shielding gas (325A at 100% with mixed gas). It is the ideal solution for fabrication shops, structural steel environments, and manufacturing lines where equipment reliability and thermal management are critical to maintaining throughput.

Advanced Consumable Technology

At the core of the Magnum PRO series is Lincoln Electric's innovative approach to expendable parts. The gun utilizes Copper Plus® Contact Tips, which feature a larger diameter and greater mass than standard tips. This design enhancement significantly improves heat dissipation, keeping the tip cooler and extending its service life. Furthermore, the patent-pending Anti-Seize™ tip and diffuser thread design mitigates the common issue of parts fusing together due to thermal cycling, ensuring that routine maintenance and tip changes are quick and frustration-free.

Ergonomics and Durability

Operator comfort is paramount in high-duty-cycle applications. The Magnum PRO 450 features a Comfort Grip™ handle, a barrel-style design that is lightweight and perfectly balanced to allow for various hand positions, reducing wrist strain and fatigue during long shifts. Structurally, the gun is built to last; the Secure-Lock™ gun tube resists rotational slipping, maintaining precise orientation, while the cable retention system ensures a positive bond that withstands the pulling and tugging inherent in industrial environments. The unit comes as a Ready-Pak, pre-assembled with a Lincoln-style connector (K466-10) and essential front-end consumables, allowing for immediate integration into your welding setup.
