K3133-1 - Magnum PRO 450 MIG Gun 10ft Air-Cooled

Built for the Toughest Jobs: Magnum PRO 450

When your day involves laying down pound after pound of wire in a shipyard or heavy fabrication shop, you need a gun that won't quit before you do. The Lincoln Electric Magnum PRO 450 Dual Procedure Welding Gun is engineered specifically for the welder who demands reliability and comfort under extreme conditions. With a 100% duty cycle at 450 amps (using CO2), this gun is ready to run all day long without overheating, letting you focus on the puddle rather than waiting for your equipment to cool down.

Comfort is not an afterthought with the Magnum PRO series. The Comfort Grip™ handle features a lightweight, balanced barrel-style design that fits naturally in your hand. This ergonomic focus helps reduce wrist strain and arm fatigue, which is essential during long shifts or when welding out of position. Whether you are welding heavy equipment or structural steel, the balance of the gun makes it easier to maneuver and control, resulting in better bead consistency and less physical wear on your body.

The "Dual Procedure" switch puts control right at your fingertips. Instead of walking back to your feeder to switch settings for a vertical-up pass or a different material thickness, you can simply flip the switch on the gun. This saves time and keeps you in the zone. Additionally, Lincoln's Copper Plus® contact tips are designed to last longer, meaning fewer trips to the tool crib for consumables and more arc-on time. The anti-seize threads on the diffuser and tip mean that when it is finally time to change consumables, you won't be fighting with fused parts. This is the industrial-grade tool professional welders trust to get the job done right.
