951196 - Miller S-74S Single Bench Feeder with 400A Bernard Gun

Heavy-Duty Industrial Wire Feeding Solution

The Miller S-74S (Single) Wire Feeder (SKU: 951196) is engineered to meet the rigorous demands of heavy manufacturing, shipbuilding, and construction environments. As part of Miller's renowned 70 Series, this bench feeder is designed for high-duty cycle applications, boasting an input circuit rating of 750 amps at 100% duty cycle. This specific package adds exceptional value by including a Bernard BTB 400A MIG gun, ensuring a premium arc delivery system right out of the box.

Advanced Drive Assembly

One of the standout technical features of the S-74S is the toolless rotatable drive assembly. This innovation allows the operator to rotate the drive housing, creating a straighter path for wire flow. By minimizing sharp bends and friction in the wire liner, feedability is significantly improved, especially with softer wires or longer gun cables. The system utilizes a four-roll drive mechanism (though this specific SKU is a single feeder unit) driven by a high-torque, permanent-magnet motor. The gear drive is sealed and utilizes ball bearings, while the speed and brake controls are solid-state, rendering the entire drive motor assembly maintenance-free for the life of the unit.

Operational Efficiency and Control

The S-74S is built to maximize uptime. The Quick-Change drive rolls allow operators to swap wire sizes without tools, reducing changeover time. The unit supports a wide wire feed speed range of 50 to 780 IPM, accommodating everything from thin gauge sheet metal work to heavy plate fabrication. It handles solid and flux-cored wire diameters ranging from 0.023 to 0.094 inches. For operator comfort, the Trigger Hold feature is standard; this allows the welder to release the trigger during long weld seams while the machine continues to feed, significantly reducing hand fatigue and repetitive strain.

Integration and Compatibility

Designed for Constant Voltage (CV) power sources, the S-74S integrates seamlessly with Miller's industrial power supplies and can be adapted for remote configurations in non-Miller boom applications. The included Bernard BTB 400A gun comes equipped with Centerfire contact tips, known for their superior conductivity and longevity. This feeder is a robust, reliable workhorse capable of withstanding the harshest industrial environments while delivering precise wire feeding performance.
