Miller SubArc Wire Drive 400 Digital Low Voltage

Reliable Feeding for Heavy-Duty Jobs

When you are laying down pounds of metal hour after hour, you need a wire feeder that won't quit. The Miller SubArc Wire Drive 400 Digital Low Voltage is built for exactly that. Designed to work perfectly with your Miller SubArc Digital power source, this drive unit takes the guesswork out of setup. It automatically communicates with the machine to ensure your parameters are locked in, giving you a smooth, consistent feed that helps prevent burn-backs and bird-nesting.

Safety is a major plus with this model. The Low Voltage (LV) design runs on 50 VDC, keeping you compliant with safety regulations while still delivering the torque needed to push heavy submerged arc wires. Whether you are running 1/16" wire for lighter passes or stepping up to 5/32" for maximum fill, the motor delivers steady torque and speed control from 30 up to 400 inches per minute.

This drive is tough enough for the shop floor but precise enough for critical code work. It mounts easily to your existing fixtures, beams, or tractors. If you are looking to upgrade your submerged arc system or replace an aging feeder, the SubArc Wire Drive 400 gives you the digital precision you need to keep your arc on track and your production moving.
