Reliable Power for Heavy-Duty Welding

When your welding projects demand continuous power and unwavering reliability, the Lincoln Electric Magnum® PRO 450 Dual Procedure MIG Gun is the tool of choice. This 20-foot assembly (K3133-3) is built to withstand the punishment of industrial workspaces while delivering the precision you expect from Lincoln Electric. Whether you are welding thick structural steel or fabricating heavy machinery, the 450A rating at 100% duty cycle ensures your gun won't overheat halfway through the job. It is the ideal upgrade for welders who need to push their machines to the limit without sacrificing performance.

Built for Comfort and Uptime

Welding fatigue can lead to mistakes and downtime, which is why the Magnum PRO 450 features a Comfort Grip™ handle. This barrel-style handle is perfectly balanced and lightweight, allowing you to weld comfortably in various positions for extended periods. The gun also utilizes Lincoln's PRO Select™ Gun Selection System, ensuring you have the right tool based on actual application amperage rather than just machine ratings. The inclusion of Copper Plus® contact tips means you spend less time changing burnt-out tips and more time laying beads, thanks to their superior heat dissipation properties.

Advanced Features for Professional Welders

This model supports Dual Procedure functionality, giving you the flexibility to toggle settings directly from the gun when paired with compatible equipment. The air-cooled design is robust and simple to maintain, featuring high-quality copper and aircraft-grade aluminum components. With a wire diameter range of 0.035" to 5/64", it is versatile enough to handle a wide variety of wire types, including solid MIG wire, pulsed MIG applications, and flux-cored wire. Invest in a gun that works as hard as you do with the Magnum PRO 450.
