OVERVIEW

Advanced Boom-Mounted Wire Feeding Solution

The Miller S-74 MPa Plus Swingarc™ (16 Ft Single) is a premium wire feeding system designed to optimize industrial welding environments. Engineered for manufacturing sectors such as heavy equipment, shipbuilding, and railcar fabrication, this system combines the advanced control of the S-74 MPa Plus feeder with the ergonomic and spatial benefits of a Swingarc boom. The 16-foot boom length significantly expands the welder's operating envelope, allowing for seamless coverage of large workpieces without the need to constantly relocate the power source or drag cables across the floor.

Precision Control and Performance

At the heart of this package is the S-74 MPa Plus control, which features dual digital meters for precise voltage and wire feed speed monitoring. When paired with Miller Invision™ MPa or XMT® MPa power sources, this feeder unlocks synergic pulsed MIG capabilities, providing superior arc control for difficult materials like aluminum or stainless steel. The four-drive-roll system ensures consistent wire delivery, minimizing bird-nesting and downtime, even with softer wires.

Operational Efficiency and Safety

The Swingarc design is a critical asset for facility safety and organization. By routing cables through the boom, the system eliminates trip hazards and protects expensive cabling from forklift traffic and shop floor debris. The counterbalance mechanism allows operators to raise, lower, and rotate the boom 360 degrees with minimal effort, reducing fatigue and improving weld cell ergonomics. This package includes a BTB 400A MIG gun, ensuring you have the heavy-duty tooling required for high-amperage applications right out of the box.

FAQ

This model features a 16-foot boom, which allows for a large working radius, effectively creating a 32-foot diameter work area when fully extended and rotated.

Yes, it comes with a BTB 400A MIG Gun, along with Centerfire contact tips.

The S-74 MPa Plus is optimized for use with Miller Invision™ MPa and XMT® MPa power sources to utilize synergic pulsed MIG features, but it is compatible with most Miller 14-pin power sources.

This specific SKU (951439) is a Single-wire model.

The Swingarc improves safety by routing cables through the boom and keeping them off the floor, which eliminates trip hazards and prevents cable damage from vehicles or hot slag.

It includes .035-.045 reversible dual V drive rolls.

Yes, the boom features 360-degree rotation and a 60-degree lift angle for maximum positioning flexibility.
