Miller RAD-400 Wire Drive Assembly

Reliable Feeding for Tough Angles

When your welding setup requires a unique configuration, the Miller 301012 RAD-400 Right Angle Drive is the problem solver you need. Sometimes, the standard straight-out wire path just doesn't work—maybe the feeder is mounted in a tight corner, or the gun cable needs to hang vertically without bending sharply. The RAD-400 changes the game by outputting the wire at a 90-degree angle, saving your liner from kinks and ensuring smooth delivery to the contact tip.

This isn't just about angles; it's about power. The RAD-400 is a "Low Speed" drive, meaning it is geared down to provide massive torque. If you are running heavy flux-cored wire or large diameter aluminum, this drive has the muscle to push it through without stuttering. The Enhanced Feed system grips the wire securely, ensuring that your arc remains stable and your puddles stay consistent, even during long welds.

Installing the RAD-400 is a direct upgrade for compatible Miller feeders, giving you the flexibility to set up your station exactly how you need it. Whether you are retrofitting an old feeder or customizing a new rig for a specific job, this drive assembly provides the durability and feed consistency that professional welders demand. Stop fighting with poor cable routing and slipping drive rolls—upgrade to the RAD-400 for a smoother, more powerful feed.
