K3420-1 - Lincoln Magnum PRO AL G225A Push-Pull Gun 15ft 12-Pin

Premium Aluminum Wire Feeding Solution

The Lincoln Electric K3420-1 Magnum PRO AL G225A Welding Gun is a high-performance push-pull system engineered specifically to address the challenges of feeding aluminum wire. In industrial environments where downtime equates to lost revenue, the reliability of your wire feeding equipment is paramount. This air-cooled gun, rated at 225 Amps at a 60% duty cycle, integrates a powerful motor within the handle to pull the wire while the feeder pushes it, ensuring a smooth, consistent arc without the frustration of bird-nesting or wire shaving.

Industrial Durability and Maintenance

Designed for the rigors of heavy fabrication, the Magnum PRO AL series features a robust construction that withstands harsh shop environments. A key advantage for maintenance teams is the tool-less access to the drive roll and liner system. Operators can quickly clear jams or change wire sizes without searching for tools, significantly reducing changeover time. The gun utilizes Lincoln's proprietary Magnum PRO consumables, which feature Copper Plus contact tip technology. This design improves heat dissipation and electrical conductivity, extending the life of the tip and reducing the frequency of consumable replacements.

Optimized for Production

The K3420-1 comes equipped with a 15-foot (4.5 meter) cable assembly, providing ample reach for working on large weldments such as trailers, boat hulls, or automotive frames. The 12-pin connector ensures seamless integration with compatible Lincoln Electric power sources and wire feeders. By combining superior feeding mechanics with high-grade consumables, this gun delivers high-quality aluminum welds with excellent bead appearance and penetration, making it an essential tool for professional fabricators.
