The Lincoln Electric Magnum® PRO AL G450W (K3357-1) is a high-performance push-pull MIG gun engineered specifically for the rigorous demands of industrial aluminum fabrication. Designed to integrate seamlessly with Lincoln Electric's advanced power sources, this gun addresses the inherent challenges of feeding soft aluminum wire over long distances. The 'G450W' designation indicates a water-cooled architecture capable of sustaining 450 Amps at 100% duty cycle, making it an ideal choice for heavy manufacturing environments where downtime for torch cooling is not an option.
At the core of the K3357-1 is a precision-engineered motor and drive roll system located in the handle, which works in synchronization with the wire feeder to pull wire from the spool and push it through the liner. This dual-action significantly reduces friction and prevents the wire buckling (bird-nesting) often associated with standard push-only systems. The gun utilizes Magnum® PRO consumables, featuring Copper Plus® technology which provides a larger mass for improved heat dissipation and electrical conductivity, extending consumable life and ensuring consistent arc performance.
The ergonomic design focuses on operator fatigue reduction. Despite the integrated motor, the handle remains balanced and lightweight. This specific model features a rear trigger configuration, preferred by many operators for its natural grip position during long welds. The 15-foot cable assembly offers substantial reach while maintaining consistent wire feed speeds. Maintenance is streamlined with a tool-less drive roll change mechanism and a split-wire guide system that ensures precise alignment.
