OVERVIEW

Advanced Dual Wire Feeding Solution for Industrial Fabrication

The Miller D-74 MPa Plus Swingarc™ (951441) is a premium dual-wire feeder system mounted on a 12-foot counterbalanced boom, designed to maximize productivity and safety in large-scale manufacturing environments. This system integrates Miller's advanced MPa Plus control technology with the ergonomic benefits of the Swingarc boom, providing a versatile solution for complex weld cells. The dual-feeder configuration allows operators to switch seamlessly between two different wire types or diameters, significantly reducing downtime associated with spool changes and setup adjustments.

Optimized Reach and Cable Management

The 12-foot boom offers a substantial operational radius, creating a 24-foot diameter work area. The counterbalance design ensures that the boom is easy to position, requiring minimal physical effort from the operator. A key feature of the Swingarc system is its in-boom cable routing, which organizes control cords, gas hoses, and weld cables internally. This not only protects expensive cabling from floor hazards and abrasion but also eliminates tripping hazards, contributing to a cleaner and safer workshop environment. The boom allows for 360-degree rotation and a 60-degree lift angle, providing exceptional access to large weldments.

Precision Control and Compatibility

At the core of this system is the D-74 MPa Plus feeder, which features a four-drive-roll system for robust and consistent wire delivery. When paired with Miller Invision™ MPa or XMT® MPa power sources, the feeder unlocks Synergic Pulsed MIG capabilities, offering superior arc control and reduced spatter. The digital interface provides clear visibility of voltage and wire feed speed, while advanced features like dual schedule control, trigger hold, and adjustable preflow/postflow settings allow for precise tailoring of the welding arc to specific application requirements. The unit operates on 24 VAC input power and supports wire feed speeds ranging from 50 to 780 inches per minute.

FAQ

This model features a 12-foot boom, which provides a 24-foot diameter work area when fully extended and rotated.

Yes, the package includes two (2) BTB 400A MIG guns, along with contact tips and drive rolls.

It is compatible with Miller 14-pin power sources. To utilize the Synergic Pulsed MIG features, it must be paired with an Invision MPa or XMT MPa power source.

This is a Dual wire feeder (D-74), allowing you to run two different wires or gas combinations simultaneously.

The feeder requires 24 VAC, 10 A, 50/60 Hz input power, typically supplied by the welding power source.

The wire feed speed is adjustable from 50 to 780 inches per minute (1.3 to 19.8 m/min).

The boom features in-boom routing, meaning the gas hoses, control cables, and weld cables run inside the boom arm, protecting them from damage and keeping the floor clear.

The shipping weight of the unit is approximately 285 lbs (129 kg).
