K4797-4 - Lincoln Magnum PRO AL FC 225 Aluminum Push-Pull Gun 50ft

Premium Aluminum Welding Performance

The Lincoln Electric Magnum® PRO AL FC 225 Air-Cooled Push-Pull Gun (K4797-4) represents a significant leap forward in aluminum wire feeding technology. Designed specifically for the fabrication and maintenance sectors where aluminum welding is critical, this gun addresses the common challenges associated with feeding soft wires over long distances. The core innovation lies in the Fixed Conduit (FC) liner system. Unlike traditional liners that can flex and cause friction, the rigid FC liner provides a smooth, consistent path for the wire, drastically reducing drag and the potential for shaving or birdnesting. This ensures that the wire delivery is precise, stable, and reliable, even when the 50-foot cable is fully extended or navigated around obstacles.

Advanced Ergonomics and Control

Beyond its feeding capabilities, the Magnum PRO AL FC 225 is engineered for operator control and comfort. The handle features a Quick Wire Feed Speed (WFS) adjustment dial, allowing welders to fine-tune their parameters directly at the arc without needing to walk back to the power source. This feature is particularly valuable in large-scale fabrication environments where the welder may be working up to 50 feet away from the machine. The gun also boasts a 360-degree rotatable tube, enabling access to tight corners and difficult welding positions without placing undue strain on the operator's wrist. The enhanced internal design includes improved strain relief and a robust trigger mechanism, ensuring the tool withstands the rigors of daily industrial use.

Compatibility and Expendables

This model comes equipped with a standard Lincoln 12-pin connector, making it plug-and-play ready for compatible Lincoln Electric power sources and wire feeders. For equipment utilizing a 7-pin receptacle, the gun can be easily adapted using the K2910-2 adapter (sold separately). The gun utilizes Magnum® PRO expendables, which are renowned for their longevity and performance. By using high-quality contact tips and diffusers, operators experience less downtime for consumable changes and more arc-on time. The K4797-4 is rated for 225 amps at a 60% duty cycle, making it an ideal choice for light to medium-duty industrial aluminum applications, auto body repair, and general metal fabrication.
