K3357-2 - Lincoln Magnum PRO AL G450W Water-Cooled Push-Pull Gun 25ft

Advanced Aluminum Welding Solution

The Lincoln Electric K3357-2 Magnum PRO AL G450W Welding Gun represents a significant leap forward in push-pull wire feeding technology. Designed specifically to address the unique challenges of welding aluminum, this water-cooled gun minimizes friction in the wire feed path, ensuring smooth, consistent delivery even with soft aluminum wires. Industrial operations that rely on high-volume aluminum fabrication will appreciate the engineering focused on reducing downtime and maintenance intervals. The integration of the patented EZ-Lock system allows operators to change or rotate barrels instantly, adapting to complex joint geometries without requiring extensive tool changes or downtime.

Maintenance efficiency is a core component of the Magnum PRO AL series. The Quick-Change Liner feature enables technicians to replace liners simply by removing a set screw, drastically cutting down the time required for routine service. Furthermore, by utilizing standard Magnum PRO consumables, this gun simplifies inventory management for facilities already using Lincoln Electric MIG platforms. The 550A expendables come standard, providing robust performance and longevity under high-amperage conditions. The G450W model is water-cooled, making it ideal for heavy-duty cycles where heat management is critical for both the equipment and the consumable life.

The K3357-2 is engineered with a 12-pin connection and a 25-foot cable, offering substantial reach for large assemblies such as trailer manufacturing or boat building. The rear trigger configuration offers an alternative ergonomic feel that many operators prefer for specific positional welding. With a wire diameter capacity ranging from 0.035 to 1/16 inch, this tool is versatile enough to handle thin gauge sheet metal as well as heavier structural aluminum components. The recessed adjustment dial on the handle ensures that wire feed speed settings remain stable, preventing accidental adjustments during active welding.
