Miller 907623 SubArc DC 800 Digital Submerged Arc Welding Machine 400V
SubArc DC 800 Digital cover most single- and twin-wire applications. These traditional transformer/rectifier power sources combine high efficiency with the highest reliability, providing best-in-class welding performance and repeatability. 50 Hz Subarc Digital Series power sources, interface controls and accessories include digital control and communication electronics designed to improve weld performance and simplify the integration of the equipment in more advanced applications.
- Air Carbon Arc Cutting and Gouging (CAC-A)
- Electroslag (ESW)
- Submerged Arc (SAW)
- 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 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.
- 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.
- 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 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.
