951535 - Miller D-74D Swingarc 12ft Dual Wire Feeder System

Industrial Efficiency with the Miller D-74D Swingarc System

The Miller D-74D Swingarc™ 12 Ft Dual Wire Feeder (SKU: 951535) is a premier solution for high-volume manufacturing environments where floor space, safety, and workflow efficiency are paramount. Designed to accommodate a variety of weld cell layouts, this system features a 12-foot boom that effectively extends the welder's reach, creating a work area diameter of up to 24 feet. The core of this package is the D-74D dual-wire feeder, which enables the simultaneous mounting of two different wire spools. This configuration is critical for industries requiring frequent switching between material types or wire diameters, such as transitioning from mild steel solid wire to flux-cored wire, eliminating the non-productive time associated with spool changes.

Engineering excellence is evident in the Swingarc's counterbalance design. This mechanism allows operators to raise, lower, and reposition the boom with minimal physical effort, reducing fatigue over long shifts. The boom offers 360-degree rotation and a 60-degree lift angle, ensuring that the wire feeder is always positioned exactly where it is needed, regardless of the size or orientation of the workpiece. Furthermore, the integrated cable management system routes all control cables, gas hoses, and power leads through the boom itself. This not only protects expensive cabling from forklift traffic and abrasive floor wear but also eliminates trip hazards, contributing to a safer industrial workspace.

This complete package is delivered ready for heavy-duty application. It includes two BTB 400A MIG guns, renowned for their durability and ergonomic comfort. The kit also comes fully equipped with Centerfire contact tips in .035 and .045 sizes, along with reversible dual V drive rolls suitable for .035-.045 wire. By integrating the feeder controls directly at the point of welding and removing the clutter of floor-dragging cables, the Miller D-74D Swingarc system optimizes the manufacturing process for sectors ranging from heavy equipment fabrication to railcar construction.
