K3422-4 - Lincoln Magnum PRO AL G450W Water-Cooled Push-Pull Gun 50ft

Reach Further, Weld Smarter

Take control of your aluminum welding projects with the Lincoln Magnum PRO AL G450W. If you have ever struggled with birdnesting or erratic feeding when welding aluminum, you know the frustration it causes. This push-pull gun eliminates those headaches by mechanically pulling the wire at the gun while the feeder pushes, ensuring a smooth, uninterrupted flow even with soft 4043 or 5356 wires. The massive 50-foot cable gives you the freedom to move around large workpieces—like boat hulls or trailers—without dragging your feeder with you.

Comfort is king during long shifts, and the G450W delivers. The ergonomic handle is designed to reduce hand fatigue, featuring a balanced weight distribution and a comfortable grip. The front trigger configuration offers a natural hand position for precise control. Because it is water-cooled, the handle stays cooler in your hand even when you are blasting 450 amps all day long, keeping you comfortable and focused on the puddle.

You will also appreciate the thoughtful design details that make life easier. The recessed wire feed speed dial is located right on the gun, letting you fine-tune your settings without walking back to the machine, yet it is protected to prevent accidental bumps. The Magnum PRO consumables are built to last, meaning you spend less time swapping tips and more time laying beads. Whether you are in a shipyard or a custom fab shop, the K3422-4 is the reliable partner you need for heavy-duty aluminum work.

Why Welders Choose the G450W:

• Smooth Feeding: Say goodbye to wire jams and burn-backs.
• Cool Operation: Water cooling keeps the front end and handle comfortable.
• Total Control: Adjust wire speed directly from the gun.
• Extreme Reach: 50 feet of freedom to weld where you need to.
