951527 - Miller S-74D Swingarc Single-Wire Feeder Package, 16 ft Boom

Miller S-74D Swingarc Single-Wire Feeder System

The Miller S-74D Swingarc™ (SKU: 951527) is a premium wire feeding solution designed to optimize weld cell layout and improve operator safety in heavy industrial environments. This package features a single-wire S-74D feeder mounted on a 16-foot boom, providing an extensive range of motion for welding large assemblies without the need to constantly reposition the power source. The S-74D model is equipped with digital meters, allowing for precise monitoring and setting of voltage and wire feed speed, ensuring consistent weld quality across production runs.

Engineered for durability and ease of use, the Swingarc system utilizes a counterbalance design that makes positioning the boom effortless. Operators can raise, lower, or rotate the boom 360 degrees with minimal resistance, reducing fatigue during long shifts. The 60-degree lift angle further enhances vertical reach, making it ideal for tall structures in industries such as shipbuilding, heavy equipment manufacturing, and railcar construction. A key technical advantage of this system is the in-boom cable routing, which organizes hoses and control cables internally. This not only creates a cleaner, safer work environment by eliminating trip hazards but also significantly extends the lifespan of the cables by protecting them from floor damage and sparks.

This complete package includes the S-74D feeder, the 16-foot boom assembly, a BTB 400A MIG gun, Centerfire contact tips, and .035-.045 reversible dual V drive rolls, providing a ready-to-weld solution for high-amperage applications. The unit is backed by Miller's True Blue 3-Year Warranty, ensuring long-term reliability.
