K3479-2 - Lincoln Magnum PRO AL Water-Cooled Push-Pull Gun 25ft

Premium Aluminum Welding with Lincoln Magnum PRO AL

The Lincoln Electric Magnum PRO AL Pistol Grip MIG Gun (K3479-2) represents the pinnacle of aluminum welding technology for industrial applications. Designed specifically to overcome the inherent challenges of feeding soft aluminum wire, this water-cooled push-pull gun ensures consistent, high-quality welds with minimal downtime. The core of its performance lies in the superior push-pull wire feeding technology, which drastically reduces friction in the wire feed path. By synchronizing the pull motor in the gun with the push motor in the feeder, the system ensures smooth delivery, preventing the birdnesting and wire deformation common in standard MIG setups.

Heavy-Duty Water-Cooled Performance

For fabrication environments requiring sustained high-amperage welding, the K3479-2 is the ideal choice. As a water-cooled unit, it is rated for 320 Amps at a 60% duty cycle, allowing for extended welding periods on thicker aluminum sections without the risk of the gun overheating. This thermal management not only protects the equipment but also ensures operator comfort by keeping the handle temperature low during long shifts. The 25-foot cable length provides excellent reach, making it suitable for large-scale fabrication, trailer manufacturing, and boat building where mobility around the workpiece is essential.

Ergonomics and Maintenance

Lincoln Electric has engineered the Magnum PRO AL with the operator in mind. The lightweight, ergonomic handle features a well-balanced pistol grip that fits comfortably in either the left or right hand, reducing fatigue during repetitive tasks. A recessed adjustment dial is conveniently located at the rear of the handle, allowing for wire feed speed adjustments at the point of weld while preventing accidental changes during operation. Maintenance is streamlined with features like the Quick-Change Liner, which can be accessed simply by removing the liner nut, and a removable drive roll cover for easy inspection. Utilizing standard Magnum PRO 550A consumables ensures that replacement parts are durable and readily available.
