K4798-1 - Lincoln Magnum PRO AL FC 450 Water-Cooled Push-Pull Gun, 15ft, 12-Pin

Precision Aluminum Welding Solution

The Lincoln Electric Magnum PRO AL FC 450 is a high-performance water-cooled push-pull gun designed specifically to master the challenges of aluminum welding. Aluminum wire, being softer and more pliable than steel, often suffers from bird-nesting and erratic feeding in standard MIG guns. This model addresses those issues head-on with its innovative Fixed Conduit (FC) Liner. The rigid, all-in-one liner construction provides a stable path for the wire, significantly improving feedability and arc stability, even over the 15-foot reach of the cable.

Engineered for heavy-duty industrial environments, this gun is rated at 450 Amps with a 60% duty cycle, making it ideal for structural aluminum fabrication, trailer manufacturing, and shipbuilding. The water-cooling system ensures the front end components remain cool during prolonged high-amperage welds, extending the life of your consumables and ensuring operator comfort. The gun features a front trigger design that offers excellent ergonomics and control.

Efficiency is key in production environments, and the Magnum PRO AL FC delivers with its Quick WFS Adjustment. A dial conveniently located at the base of the handle allows welders to fine-tune wire feed speed directly at the arc, eliminating the need to walk back to the power source. Internally, the gun boasts enhanced strain relief and trigger mechanics, reducing maintenance needs and increasing overall durability. Compatible with Lincoln Electric's premium Magnum PRO expendables, this gun ensures you spend more time welding and less time changing contact tips.
