K3133-4 - Lincoln Magnum PRO 450 Dual Procedure MIG Gun, 25ft Cable, 450A

Heavy-Duty Comfort and Control

When you are 20 feet up on a scaffold or deep inside a ship hull, the last thing you want to do is climb back down to your wire feeder to change your voltage. The Lincoln Electric Magnum® PRO 450 Dual Procedure MIG Gun (K3133-4) solves this problem with a built-in switch right on the handle. With a simple click, you can jump between two pre-set weld modes, giving you total control over your arc without breaking your workflow. This 25-foot gun is built for the professional welder who demands both power and convenience in the toughest shop environments.

Comfort is king during long shifts, and the Magnum PRO 450 delivers with its Comfort Grip™ design. The barrel-style handle is lightweight, balanced, and ergonomically shaped to reduce hand fatigue, no matter how you hold the torch. Despite its comfort, this gun is a beast when it comes to performance. It is rated at a full 450 amps at 100% duty cycle (CO2), meaning you can run hot and fast all day long without the gun overheating or failing. The industrial-grade construction features high-quality copper and aircraft-grade aluminum parts that stand up to drops, drags, and sparks.

Stop fighting with seized contact tips. This gun uses Lincoln's Copper Plus® tips with Anti-Seize™ thread technology. The tips are bigger and heavier to pull heat away from the wire, lasting longer than standard tips, while the special threads ensure they screw off easily even after hours of high-amperage welding. Whether you are welding thick structural plate or fabricating heavy machinery, the K3133-4 gives you the reach, the power, and the control to get the job done right the first time. It comes ready to weld with a 25-foot lead, perfect for covering large workpieces without moving your power source.
