Features

Miller's SubArc DC Series
Miller's SubArc DC Series, transformer/rectifier power sources combine high efficiency with the highest reliability. These machines feature a highly reliable thyristor power regulation. Newly designed digital control and communication electronics improve weld performance and simplify the integration of the equipment in more advanced applications.
Low-voltage accessory operation and improved environmental protection
The new Digital Series accessories are powered with 24 VAC control voltage from the power source. All power sources, interface controls and wire drives are IP-23 rated providing a high level of protection for harsh environments.
Easy to integrate
Our new SubArc power sources are easy to integrate by using a standard Modbus® connection. Different levels of integration are possible, from simple remote operation to more complex automated systems.
Easy paralleling
Easy Paralleling of two machines to increase maximum welding current is simply done by connecting the paralleling cable from the first unit to the second unit. Daisy chaining multiple machines to gain higher output is done in the same way. No special tools, laptop or software needed... plug and play.
Easier setup and operation
The SubArc Digital Series Interface controls recognize the power source and wire drive connected, and automatically configure the system for proper operation.
Easy-to-understand interface
The easy-to understand interface provides the operator with the necessary controls to set process parameters and control output.
Improved flux delivery system
Our new SubArc Flux Hopper utilizes a flux valve mechanism that assures continuous delivery of flux to the arc. The unique valve design provides a barrier between the flux and actuation device to prevent jamming of the solenoid actuator due to dust and debris. A sight glass is provided on the front of the flux hopper allowing the weld operator to visually monitor the remaining flux in the hopper.
Insight Core™ Capable
Insight Core™ is a flexible, internet-based industrial welding information management solution that can help your operation be more competitive and profitable by delivering accurate, decision-ready information about welding processes.  Learn More

Submerged Arc Welding
Improving Productivity in Submerged Arc Welding Applications
By increasing travel speeds, reducing weld passes and minimizing arc-off activities, it is possible to improve productivity in the submerged arc welding (SAW) process. Joint design, polarity, torch configuration and flux/wire selection also play a critical role in helping companies get ahead.
Georgia Machine Shop Triples Deposition Rate with Submerged Arc System and Metal-Cored Wire
Seeking greater productivity and efficiency, especially on larger weld build-up jobs that could take days or even weeks to complete, Capital City Machine Shop knew it needed a new submerged arc welding (SAW) solution. Capital City’s investment in two SubArc AC/DC 1000 Digital welding power sources, coupled with a switch to Hobart® metal-cored wire, resulted in productivity increases of 240 percent on some jobs and deposition rates triple what they experienced with their previous system from another manufacturer.
Advantages of Cored Wire in Submerged Arc Welding Applications
Understanding the important roles of the flux and wires can help companies realize the full potential of the submerged arc welding (SAW) process. The numerous advantages SAW offers for productivity and weld quality — especially when paired with cored wire specifically formulated for the process — make the investment one to consider for many heavy industrial applications.
