The Lincoln Electric Magnum® PRO AL FC 225 Air-Cooled Push-Pull Gun (K4797-2) is a specialized tool designed to master the challenges of aluminum MIG welding. Aluminum wire is notoriously soft and prone to buckling, kinking, and "birdnesting" when pushed through standard MIG torches over long distances. This push-pull system eliminates those frustrations by incorporating a motor within the gun handle that pulls the wire while the feeder pushes it, maintaining constant tension and smooth delivery. This model features a 25-foot cable, providing excellent reach for large fabrication projects without sacrificing feeding reliability.
What sets the "FC" model apart is its Fixed Conduit Liner. Unlike standard flexible liners that can allow soft wire to compress and drag, the rigid all-in-one liner in this gun provides a stable path for the wire. This design drastically reduces friction and ensures that 4043 and 5356 aluminum wires feed consistently, even when the cable is curved. The result is a stable arc, fewer burn-backs, and higher quality welds.
Built for the rigors of industrial environments, the Magnum PRO AL FC 225 features an enhanced internal design with robust strain relief and a durable trigger mechanism. For operators who need on-the-fly adjustments, a convenient Wire Feed Speed (WFS) dial is located at the base of the handle, allowing parameter changes without returning to the power source. The gun is rated for 225 amps at a 60% duty cycle, making it suitable for a wide range of manufacturing, automotive, and repair applications. It connects directly to Lincoln Electric power sources with a 12-pin receptacle, ensuring seamless integration with your existing equipment.
This gun utilizes Lincoln's premium Magnum PRO expendables. These consumables are designed with Copper Plus® technology, which provides better heat dissipation and electrical conductivity than standard tips. This extends the life of the contact tips and nozzles, reducing the frequency of changeovers and keeping your production line moving. The package includes 3/64" drive rolls and front-end parts, readying you for the most common aluminum wire sizes right out of the box.
