What is it?
The Auto-Continuum is Miller Electric's flagship robotic multi-process welding system, designed for production cells requiring RMD root pass welding and pulsed MIG fill/cap welding from a single power source.
Who is it for?
Pipe fabrication shops automating root-to-cap welding sequences. Structural steel fabricators automating multi-pass welds. Automotive manufacturers requiring consistent root and fill bead quality from a single robotic cell investment.
Key specs
- Processes: Pulsed MIG, RMD, Accu-Pulse, standard MIG
- Output: Up to 600 A
- Multi-process: Switch between RMD and pulsed MIG in same cell
- Robot integration: Fanuc, ABB, KUKA, Yaskawa
- Communication: Miller ArcReach + EtherNet/IP, DeviceNet
- Wire feeders: Robotic wire feeder compatible
- Origin: US
RMD process significance
RMD (Regulated Metal Deposition) is Miller's modified short-circuit process that precisely controls the weld puddle at the moment of wire-to-puddle short circuit, enabling consistent root pass penetration in pipe and structural welding. RMD is faster than traditional TIG root passes and more consistent than conventional short-circuit MIG in out-of-position pipe welding.
Limitations
- Power source only — requires robot arm and torch
- Miller-proprietary process names (RMD, Accu-Pulse) = limited cross-brand comparison
- Higher cost than single-process robotic power sources
- ArcReach communication preferred (requires compatible wire feeders)
FAQ
What is RMD welding?
RMD (Regulated Metal Deposition) is Miller Electric's modified short-circuit MIG process that controls the weld puddle at the moment of short circuit, enabling consistent root pass penetration in pipe and structural welding without the spatter and inconsistency of conventional short-circuit MIG.
Can Auto-Continuum switch processes during a weld sequence?
Yes. The Auto-Continuum can switch between RMD (root pass), pulsed MIG (fill), and Accu-Pulse (cap) in a programmed sequence within the same cell without changing equipment, enabling complete pipe or structural weld automation.
What robots work with Auto-Continuum?
Auto-Continuum integrates with Fanuc, ABB, KUKA, and Yaskawa robot controllers via EtherNet/IP and DeviceNet fieldbus protocols.
What is Accu-Pulse?
Accu-Pulse is Miller's high-deposition pulsed MIG process optimised for fill and cap passes in multi-pass welding, providing high travel speed with good bead appearance and reduced spatter.
Is Miller Electric a US company?
Yes. Miller Electric is a US manufacturer headquartered in Appleton, Wisconsin, founded in 1929 and a subsidiary of ITW (Illinois Tool Works) since 1993.
