The Lincoln Electric Magnum PRO AL G225A is a premium air-cooled push-pull gun designed specifically to address the challenges of feeding aluminum welding wire. Identified by the internal SKU K3356-2, this model features a 25-foot cable assembly and a unique rear trigger configuration, catering to welders who prefer a different grip style or require specific ergonomic positioning during fabrication. The gun is engineered to optimize the feeding of soft aluminum wires, such as 4043 and 5356 series, which are prone to bird-nesting and friction issues in standard push-only systems.
Rated at 225 Amps at a 60% duty cycle using 100% Argon gas, the G225A provides sufficient power for a wide range of light to medium-duty aluminum fabrication tasks. The push-pull mechanism utilizes a motor within the gun handle to pull the wire while the wire feeder pushes it, synchronizing the feed speed to ensure smooth, consistent delivery over the extended 25-foot distance. This system drastically reduces friction and wire deformation. The gun connects via a standard 7-pin Amphenol connector, making it compatible with various Lincoln Electric power sources and wire feeders equipped for push-pull operation.
A key advantage of this gun is its integration with the Magnum PRO consumable platform. It utilizes Copper Plus contact tips, which feature a larger mass and diameter compared to standard tips. This design improves heat dissipation and electrical conductivity, resulting in longer tip life and fewer burn-backs. The consumables also feature Anti-Seize threads to prevent the contact tip and diffuser from fusing to the gun tube, a common issue in high-heat aluminum welding applications. The G225A is designed for easy maintenance, featuring a tool-less Quick-Change liner system that simplifies the replacement of worn liners, minimizing downtime in industrial environments.
The "Rear Trigger" design of the K3356-2 places the trigger mechanism at the back of the handle grip area. This configuration can be advantageous for operators who manipulate the torch in ways where a front trigger is awkward or prone to accidental activation. The handle itself is lightweight and balanced to reduce wrist strain during long welding sessions. Additionally, the wire feed speed adjustment dial is recessed into the handle base, allowing for convenient fine-tuning at the arc while preventing accidental adjustments if the gun is bumped against the workpiece.
