OVERVIEW

Maximize Efficiency with the Miller D-74D Swingarc System

The Miller D-74D Swingarc™ (951536) is a premier dual-wire feeder solution designed to optimize industrial welding cells. By mounting the high-performance D-74D feeder on a counterbalanced 16-foot boom, Miller has created a system that dramatically increases workspace flexibility while reclaiming valuable floor space. This configuration is ideal for manufacturing environments where large weldments require extended reach and mobility without the clutter of cables dragging across the floor.

Dual-Wire Capability for Versatility

The "Dual" in D-74D stands for efficiency. This unit allows welders to run two different types of wire—such as mild steel and stainless, or two different diameters—simultaneously. Switching between processes is as simple as picking up the other gun, eliminating the downtime associated with changing spools and drive rolls. The package includes two BTB 400A MIG guns, ensuring you have the heavy-duty capacity needed for high-amperage applications right out of the box.

Superior Boom Mechanics

The 16-foot boom is engineered with a sophisticated counterbalance design, making it effortless to raise, lower, or reposition the feeder. With 360-degree rotation and a 60-degree lift angle, the operator can access virtually any point within a 32-foot diameter circle. This range of motion is critical for shipbuilding, heavy equipment manufacturing, and railcar fabrication. Furthermore, the in-boom cable routing keeps gas lines and control cables organized and protected from shop floor hazards, significantly extending the life of your equipment.

Reliability and Control

Powered by Miller's industrial-grade drive motors, the D-74D delivers consistent wire feeding speeds, crucial for maintaining arc stability and weld quality. The system integrates seamlessly with Miller's 14-pin power sources, providing a unified and reliable welding station. Backed by Miller's True Blue 3-Year Warranty, this Swingarc package is an investment in long-term productivity and safety.

FAQ

The boom itself is 16 feet long. When combined with the reach of the included MIG guns and the rotation capability, it covers a work area diameter of approximately 32 feet.

Yes, the D-74D is a dual-wire feeder. You can load two different spools of wire (e.g., different materials or diameters) and switch between them instantly without changing rolls.

The package includes two (2) BTB 400A MIG guns, suitable for heavy-duty industrial welding applications.

The counterbalance design uses mechanical leverage to offset the weight of the boom and feeder, allowing the operator to raise, lower, or swing the unit with minimal physical effort.

The D-74D Swingarc is compatible with Miller power sources that utilize a 14-pin connection, such as the Dimension, XMT, and Deltaweld series.

Yes, the Swingarc boom features in-boom cable routing which organizes and protects hoses and control cables, keeping the workspace clean and safe.

The system is covered by Miller's True Blue 3-Year Warranty.

Yes, it includes two sets of .035-.045 reversible dual V drive rolls.
