The Lincoln Electric Magnum PRO AL G225A (SKU: K3420-2) is a premium air-cooled push-pull MIG gun engineered specifically to address the challenges of feeding aluminum wire. Designed for industrial fabrication environments, this 225-amp gun features a 25-foot (7.6 meter) cable assembly, providing extended reach for large weldments such as trailers, boats, and signage. The unit connects via a 12-pin Amphenol connector, ensuring seamless integration with compatible Lincoln Electric wire feeders and power sources.
The G225A utilizes a high-torque motor located in the handle to pull the wire while the feeder pushes it, maintaining constant tension and preventing the buckling common with soft aluminum wires. It is rated for 225 Amps at 60% duty cycle using mixed shielding gases. The gun comes factory-equipped to run 0.035" to 3/64" (0.9-1.2 mm) aluminum wire. Key to its performance is the integration of the Magnum PRO consumable system. These consumables feature Copper Plus technology, which provides a larger mass for heat dissipation, keeping tips cooler and extending their service life compared to standard consumables.
Lincoln Electric has designed the K3420-2 for minimal downtime. The Quick-Change Liner system allows maintenance personnel to replace liners without disassembling the gun or using tools. The drive roll cover features a flip-top design for immediate access to the wire drive mechanism, facilitating quick clearing of any debris or wire shavings. The split-wire guide design ensures precise alignment, further reducing the risk of feeding errors. This gun is an essential asset for any facility prioritizing high-volume, high-quality aluminum welding.
