OVERVIEW

Industrial Grade Aluminum Welding Solution

The Lincoln Electric Magnum PRO AL G450W (K3422-4) is a high-performance push-pull MIG gun engineered specifically for the rigorous demands of industrial aluminum fabrication. Designed to address the common challenges associated with feeding soft aluminum wire, this system utilizes a synchronized push-pull mechanism that ensures consistent wire delivery over its extended 50-foot length. This capability is critical for large-scale manufacturing environments, such as trailer fabrication, shipbuilding, and automotive assembly, where operators require significant mobility without sacrificing arc stability.

At the core of this unit is the G450W water-cooled rating, providing a 100% duty cycle at 450 Amps using mixed shielding gases. This thermal management allows for continuous welding operations without the risk of gun overheating, maximizing throughput in high-volume production lines. The gun integrates seamlessly with Lincoln Electric's advanced power sources via a 12-pin connector, enabling precise communication and control.

Maintenance and operational costs are optimized through the use of Magnum PRO consumables. The proprietary Copper Plus contact tips feature a larger mass and diameter, improving heat dissipation and electrical conductivity. This results in significantly longer tip life compared to standard consumables, reducing downtime for changeovers. The Quick-Change liner system further enhances serviceability, allowing maintenance teams to replace liners in seconds without disassembling the entire gun.

FAQ

The Magnum PRO AL G450W is rated at 450 Amps at 100% duty cycle with mixed gas.

Yes, this is a water-cooled gun (G450W) and requires a compatible water cooler and coolant to operate safely.

It comes with a 12-pin connector, typically used with Lincoln Electric Power Wave and other advanced wire feeders.

While primarily designed for aluminum with a push-pull system, it can technically run steel wire if the correct liner and drive rolls are installed, though standard push guns are usually preferred for steel.

It uses Lincoln Electric Magnum PRO consumables, including Copper Plus contact tips and Magnum PRO nozzles.

There is a recessed adjustment dial located on the bottom of the gun handle for convenient wire feed speed control.

It is designed to handle aluminum wire diameters from 0.035 inch to 1/16 inch (0.9 mm to 1.6 mm).

No, the gun features a Quick-Change liner system that allows for liner replacement without disassembling the gun handle.
