951442 - Miller D-74 MPa Plus Swingarc Dual Wire Feeder System 16ft Boom

Industrial Reach and Dual-Wire Efficiency

The Miller D-74 MPa Plus Swingarc™ Dual Wire Feeder (951442) is a premier solution for large-scale industrial welding environments where floor space, safety, and reach are critical. Designed to accommodate complex weld cell layouts, this system features a substantial 16-foot boom that effectively quadruples the working area compared to standard bench-top feeders. The dual-wire configuration is a significant asset for fabrication shops requiring frequent changes between wire types or diameters, such as switching between solid and flux-cored wires or different material grades, without the downtime associated with changing spools and drive rolls.

Engineered for heavy manufacturing sectors like shipbuilding, railcar construction, and heavy equipment fabrication, the Swingarc™ system integrates a counterbalance design that makes positioning the boom effortless. Operators can rotate the unit 360 degrees and utilize a 60-degree lift angle to access hard-to-reach joints while keeping the wire feeder controls close at hand. This flexibility ensures that the welder can maintain an optimal arc without dragging heavy cables across the floor, thereby reducing operator fatigue and tripping hazards.

The D-74 MPa Plus control technology offers advanced performance for pulse welding applications when paired with compatible Miller power sources. The package is comprehensive, including two BTB 400A MIG guns, ensuring the unit is ready for high-amperage duty cycles right out of the box. Cable management is streamlined through in-boom routing, which organizes gas hoses, control cables, and power leads, protecting them from wear and tear and further contributing to a cleaner, safer work environment.
