K3355-2 - Lincoln Magnum PRO AL G225A Push-Pull MIG Gun 25ft Rear Trigger

Advanced Aluminum Wire Feeding Solution

The Lincoln Electric Magnum PRO AL G225A (K3355-2) is a high-performance push-pull MIG gun engineered specifically to address the challenges of welding with aluminum wire. Aluminum is inherently soft and pliable, making it difficult to push through standard MIG torches over long distances without buckling or "bird-nesting." The G225A solves this by incorporating a powerful motor within the gun handle that works in synchronization with the wire feeder's motor. This push-pull action ensures consistent, smooth wire delivery over the extended 25-foot cable length, allowing operators to work on large assemblies like trailers, boats, and tanks without moving the power source.

Magnum PRO Consumable Technology

A standout feature of this gun is its compatibility with Lincoln's Magnum PRO consumables. These consumables are designed with Copper Plus technology, which provides a larger mass of copper in the contact tip. This design improves heat dissipation, keeping the tip cooler during high-amperage welding. Cooler tips reduce the likelihood of the wire fusing to the tip (burn-back) and extend the overall lifespan of the consumable, significantly lowering operational costs and downtime associated with frequent tip changes. The anti-seize threads on the contact tips and diffusers further ensure that maintenance is quick and frustration-free.

Ergonomics and Maintenance

The K3355-2 model features a Rear Trigger configuration. While many standard guns use a front trigger, the rear trigger placement can offer superior comfort and control for specific welding positions or operator preferences, reducing hand strain during long shifts. The handle itself is lightweight and balanced to minimize fatigue. Maintenance is streamlined with a tool-less drive roll system and a quick-change liner, allowing welders to swap out components right on the shop floor without needing a toolbox. The gun also features a recessed wire feed speed adjustment dial at the base of the handle, allowing for convenient parameter changes without the risk of accidental bumps altering the settings.

Industrial Reliability

Rated at 225 Amps at 60% duty cycle with 100% Argon gas, the G225A is built for industrial environments. It connects via a robust 12-pin connector, ensuring seamless communication with compatible Lincoln Electric wire feeders. Whether used in automotive manufacturing, shipbuilding, or general aluminum fabrication, the Magnum PRO AL G225A delivers the precision and reliability required for high-quality aluminum welds.
