The Lincoln Electric K3355-1 is a specialized air-cooled push-pull MIG gun designed specifically for the rigorous demands of aluminum welding. Designated as the Magnum PRO AL G225A, this unit is rated for 225 Amps at a 60% duty cycle, making it suitable for medium-duty industrial fabrication. The core of its performance lies in the superior push-pull wire feeding technology, which mechanically assists the wire at the gun end, significantly reducing friction in the liner and preventing the buckling or 'birdnesting' common with soft aluminum wires (4043/5356 series).
This model features a 15-foot cable assembly terminated with a standard Lincoln 12-pin connector, ensuring compatibility with a wide range of Lincoln Electric power sources equipped for push-pull operation. The gun is engineered to handle wire diameters ranging from 0.035 inches to 1/16 inches (0.9 - 1.6 mm). A key maintenance feature is the Quick-Change Liner system, which allows operators to replace the liner by simply removing a set screw, minimizing downtime. Additionally, the patented EZ-Lock system permits the barrel to be rotated or changed entirely to suit different joint access requirements.
The K3355-1 utilizes standard Magnum PRO consumables (Copper Plus contact tips and nozzles), which are designed for better heat dissipation and longer service life compared to standard consumables. The drive roll system is easily accessible via a flip-up cover located at the thumb rest, and the package includes an insulated groove drive roll and an insulated idler roll to ensure consistent arc stability without electrical shorting.
