951780001 - Miller 20 Series Digital Feeder with Q4015 Gun and Drive Rolls

Industrial Precision with the Miller 20 Series Digital Wire Feeder

The Miller 20 Series Digital Wire Feeder (951780001) is engineered for heavy-duty industrial manufacturing and fabrication environments. Designed as a direct replacement for the legacy S-22A and S-24A models, this unit integrates seamlessly with any Miller MIG welding power source equipped with a standard 14-pin receptacle. It operates on 24 VAC input power and features a robust 16-gauge sheet metal housing, ensuring durability in harsh shop conditions.

At the core of the 20 Series is a four-roll, gear-driven drive system that provides positive, slip-free wire feeding for a wide variety of wire types and diameters, ranging from .023 inch to 5/64 inch. The digital meter interface offers operators precise control over voltage and wire feed speed, with a broad speed range of 75 to 750 inches per minute. This model includes remote voltage control and adjustable run-in control, optimizing arc starting performance and allowing parameter adjustments directly at the weld cell.

This package is supplied as a complete turnkey solution, including a 15-foot Bernard BTB 400A MIG gun (Q4015) and a 10-foot interconnecting cord. It also comes equipped with Miller's AccuLock S consumables system, designed to reduce contact tip changes and troubleshooting time. The inclusion of reversible dual V drive rolls for .035 and .045 inch wires ensures immediate readiness for common fabrication tasks.

Key Technical Specifications

The feeder incorporates advanced motor ramp and burnback control, delivering excellent wire starting and stopping characteristics to prevent wire stubbing. The trigger hold function is a standard feature, allowing operators to perform long, continuous welds without maintaining trigger pressure, thereby reducing hand fatigue. With a weight of 46 lbs and compact dimensions, it mounts easily to standard booms or carts.
