Lincoln Electric Magnum PRO AL G225A Push-Pull Gun (K3421-3)

The Lincoln Electric Magnum PRO AL G225A is a high-performance push-pull MIG gun engineered specifically to overcome the challenges of feeding aluminum wire. With a generous 35-foot cable and a robust 225-amp air-cooled rating, this gun is an essential tool for fabricators working on trailers, boats, and signage who require extended reach without sacrificing feedability. The K3421-3 model features a 7-pin connector, making it compatible with a wide range of Lincoln Electric wire feeders and power sources.

Designed for industrial environments, the Magnum PRO AL series integrates Lincoln's premium Magnum PRO consumables. The Copper Plus contact tips provide a larger heat dissipation area, keeping tips cooler and lasting longer than standard consumables. This translates to less downtime for tip changes and higher productivity in your shop. The gun's front trigger design and ergonomic handle ensure operator comfort during long welding shifts.

Key Features for the Industrial User:

• Reliable Feeding: The push-pull mechanism ensures soft aluminum wire is fed consistently over long distances, preventing bird-nesting and erratic arcs.


• Durability: Built with industrial-grade components to withstand harsh shop environments.


• Convenience: Includes a tool-less quick-change liner system and a wire feed speed adjustment dial located directly on the handle.
