The Lincoln Electric Magnum PRO AL G225A Push-Pull MIG Gun (K3421-2) is engineered to solve the specific challenges associated with feeding aluminum welding wire. Unlike standard push guns that often struggle with soft aluminum wires—leading to friction, buckling, and the dreaded "birdnesting"—this advanced push-pull system utilizes a motor in the gun handle to pull the wire while the feeder pushes it. This synchronized action ensures smooth, consistent delivery of wire to the weld puddle, even over the extended 25-foot cable length.
Rated at 225 Amps at 60% duty cycle, the G225A is an air-cooled solution perfect for general fabrication, automotive, and boat building applications. The gun features a lightweight, ergonomic handle designed to minimize operator fatigue. A recessed adjustment dial located conveniently at the bottom of the handle allows welders to fine-tune wire feed speed without returning to the power source, enhancing productivity and focus.
This gun utilizes Lincoln's premium Magnum PRO consumables. The Copper Plus® contact tips feature a larger diameter and mass, improving heat dissipation and extending tip life significantly compared to standard tips. The anti-seize threads on the contact tips and diffusers prevent fusing, making consumable changes quick and hassle-free. The patent-pending Anti-Seize™ tip and diffuser thread design reduces part replacement costs and downtime.
The K3421-2 model comes equipped with a 7-pin connector, making it directly compatible with select Lincoln Electric power sources such as the Power MIG® 350MP and Power Wave® systems. The EZ-Lock™ system allows the gun barrel to rotate 360 degrees or be interchanged easily, providing flexibility for welding in difficult-to-reach areas. Maintenance is simplified with a tool-less drive roll cover and a quick-change liner system.
