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

Optimize Your Aluminum Fabrication

Take control of your aluminum welding projects with the Lincoln Electric Magnum PRO AL Pistol Grip Push-Pull Gun (K3479-2). This 25-foot, water-cooled MIG gun is engineered to deliver a premium welding experience by integrating advanced features that reduce downtime and improve feedability. Aluminum wire is notoriously difficult to feed due to its softness, often leading to friction and jamming in standard guns. The Magnum PRO AL solves this with its industrial-grade push-pull drive system, which pulls the wire through the liner while the feeder pushes it, ensuring a smooth, uninterrupted flow essential for high-quality aluminum beads.

Built for the Shop Environment

The K3479-2 is built to withstand the rigors of daily industrial use. It features a robust design that includes a removable drive roll cover, granting quick access to the wire and drive rolls for cleaning or adjustment. The gun connects directly to Lincoln Electric welders equipped with a 12-pin receptacle, ensuring seamless integration with your existing power sources. For those using 7-pin receptacles, an optional adapter (K2910-2) makes this gun versatile across different machine generations. The water-cooled architecture supports a 320A output at 60% duty cycle, making it a powerhouse for auto body repair, metal fabrication, and light industrial work.

Superior Consumables and Handling

Efficiency in the shop is driven by equipment reliability and ease of use. This gun utilizes Lincoln's renowned Magnum PRO consumables, specifically the 550A series, which are standard across the PRO AL line. These consumables are designed for extended life, reducing the frequency of contact tip changes. The pistol grip design offers superior control and maneuverability, while the recessed adjustment dial ensures your settings stay locked in. Whether you are welding thin gauge aluminum sheet or heavier structural components, the Magnum PRO AL provides the consistency and comfort needed to produce professional results every time.
