Arc welder Subarc series

three-phaseDCthyristors

Digital Series of 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. 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. The easy-to understand interface provides the operator with the necessary controls to set process parameters and control output. 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. 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. 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.
