300497 - Miller Spoolmate 200 Aluminum MIG Spool Gun 20ft 160A

Reliable Aluminum Wire Feeding Solution

The Miller Spoolmate 200 Series Spool Gun (300497) is engineered to provide consistent and reliable wire feeding for light industrial aluminum welding applications. Rated at 160 amps at a 60% duty cycle, this spool gun is designed to overcome the common challenges associated with feeding soft aluminum wire through standard MIG torches. By locating the wire spool directly on the gun, the Spoolmate 200 eliminates the friction and drag of long liners, ensuring smooth arc performance and preventing wire tangling or "birdnesting." This unit is specifically optimized for use with 4000 and 5000 series aluminum wires ranging from .023 to .035 inches in diameter.

Industrial Design and Ergonomics

Built for the shop environment, the Spoolmate 200 features a robust cast aluminum gearbox and a heavy-duty motor that ensures longevity even under frequent use. The 20-foot (6-meter) direct-connect cable provides substantial reach, allowing operators to work on large projects—such as truck beds, trailers, or marine hulls—without constantly moving the power source. The cable assembly includes a heavy-duty strain relief to protect connections and extend the service life of the equipment. Furthermore, the gas lines are routed internally, a critical design feature that prevents the gas hose from snagging on fixtures or the workpiece, thereby maintaining a safer and more efficient work area.

Maintenance and Compatibility

Efficiency in maintenance is key for industrial operations. The Spoolmate 200 addresses this with a toolless barrel removal system and an easy-access drive assembly, allowing for quick drive roll changes or cleaning without complete disassembly. The clear, hinged wire spool cover provides immediate visual confirmation of remaining wire, reducing unexpected downtime. This spool gun is directly compatible with several industry-standard Miller power sources, including the Millermatic 212 Auto-Set, Millermatic 251, Millermatic 252, Millermatic 255, and Multimatic 235, making it a versatile addition to existing equipment fleets.
