K3358-1 - Lincoln Magnum PRO AL G450W Water-Cooled Push-Pull Gun, 15ft, Rear Trigger

Industrial Aluminum Welding Solution

The Lincoln Electric Magnum PRO AL G450W (K3358-1) is a high-performance push-pull MIG gun engineered specifically to overcome the challenges of feeding aluminum wire. Aluminum welding requires precise wire delivery to prevent bird-nesting and ensure consistent arc stability; the G450W utilizes a robust push-pull motor system that synchronizes with the wire feeder to deliver smooth, uninterrupted feeding even over the 15-foot cable length. This model features a Rear Trigger configuration, offering an alternative ergonomic grip that some operators prefer for specific positional welding or personal comfort.

High-Duty Cycle Performance

Designed for heavy industrial environments, the G450W is water-cooled, allowing it to operate at 450 Amps at 100% duty cycle using mixed shielding gases. This thermal management is critical for high-volume manufacturing where downtime for torch cooling is not an option. The gun integrates Lincoln's proprietary Magnum PRO consumables, including Copper Plus contact tips which provide a larger heat dissipation area and superior electrical conductivity, significantly extending consumable life and reducing replacement frequency.

Ergonomics and Maintenance

Operator fatigue is minimized through a lightweight, balanced handle design and a flexible cable jacket. The gun features a tool-less, quick-change liner system and a flip-up drive roll cover, making routine maintenance fast and simple on the shop floor. The recessed wire feed speed adjustment dial is strategically placed to allow easy changes when needed while preventing accidental adjustments during welding. This unit comes equipped with a 7-pin connector, ensuring compatibility with a wide range of Lincoln Electric power sources and wire feeders designed for push-pull operation.
