The Lincoln Electric Magnum® PRO AL G225A Welding Gun (K3356-4) is a premier solution designed specifically to overcome the challenges of feeding aluminum wire. Aluminum welding requires consistent, smooth wire delivery to prevent bird-nesting and burn-back, issues that are compounded when working at significant distances from the power source. This model features a robust push-pull system that synchronizes the wire feed motor in the gun with the wire feeder at the machine, ensuring delicate aluminum wire is fed reliably through the entire 50-foot (15.2 meter) cable assembly.
Engineered for industrial environments, the G225A is air-cooled and rated for 225 amps at a 60% duty cycle, making it suitable for a wide range of fabrication and repair applications. The K3356-4 model is distinguished by its Rear Trigger configuration. This ergonomic variation is preferred by many operators for specific out-of-position welding tasks or personal comfort preferences, offering a different grip dynamic compared to standard top-trigger models. The gun connects via a standard Lincoln 7-pin connector, ensuring compatibility with a variety of Lincoln Electric power sources and wire feeders equipped for push-pull operation.
One of the most significant benefits of the Magnum PRO AL series is its integration with the Magnum PRO consumable platform. These consumables are designed with Copper Plus® technology, which provides a larger mass and contact area to dissipate heat more effectively. This results in significantly longer contact tip life compared to standard consumables, reducing downtime for tip changes and lowering overall operating costs. The anti-seize thread design on the contact tips and diffusers further prevents the components from fusing together, even after long hours of high-heat welding.
The gun is built with the welder's comfort and efficiency in mind. It features a tool-less flip-top drive roll cover, allowing for quick and easy access to the wire drive mechanism for maintenance or wire changes. A recessed wire feed speed adjustment dial is conveniently located on the handle, allowing the operator to fine-tune settings at the arc without returning to the machine. The lightweight, curved handle is balanced to minimize wrist strain during extended use, while the 50-foot cable provides exceptional mobility for working on large projects such as trailers, boats, or large structural assemblies.
