The new SubArc Digital Series of power sources, interface controls and accessories from Miller Electric Mfg. Co. includes digital control and communication electronics designed to improve weld performance and simplify the integration of the equipment in more advanced applications.

Product details

The SubArc Digital Series offers a number of significant enhancements, including easier setup and operation and an improved flux delivery system that ensures continuous delivery of flux to the arc.

The series combines the latest in digital process control technology with tested and highly reliable power regulation and the ease of use and reliability of a traditional machine 黑料社� resulting in equipment that stands up to use in all heavy industrial applications.

黑料社淭his new equipment with digital controls is easy to operate and understand, thereby providing proper penetration and optimum deposition through controlled regulation of parameters, making it less dependent on the skill level of the operator,黑料社� said Pieter Keultjes, Miller Global Product Manager, SubArc Equipment.

黑料社淭his extremely reliable process meets the quality and mechanical properties required by even the most demanding industries 黑料社� such as shipbuilding, heavy fabrication, pressure vessel, wind tower and pipe manufacturing 黑料社� using tested power technology that has offered continuous reliability for decades. It really offers the best of both worlds.黑料社�

Power sources

The product line includes two DC power source models 黑料社� the SubArc DC 650/800 Digital and the SubArc DC 1000/1250 Digital 黑料社� and one AC/DC model, the SubArc AC/DC 1000/1250 Digital.

The power sources have the capacity to handle Submerged Arc (SAW) and Electroslag (ESW) welding applications, from traditional DC single-arc to multi-wire tandem welding. In the case of ESW welding or other high-current demand, two or more power sources can easily be paralleled.

In addition to these power source options, the series offers two interface controls 黑料社� analog and digital 黑料社� and a range of wire drive motors and accessories, including single- and twin-wire torches, narrow gap torches, and internal and external cladding heads. The accessories are powered with a safe, low control- voltage (24 VAC) from the power source.

Digital communication

New digital communication within the equipment recognises the power source and wire drive connected and automatically configures the system for proper operation, providing easier setup and operation. The easy-to-understand interface provides the operator with the necessary controls to set process parameters and control output, and the power sources feature simplified parallel and tandem setups 黑料社� just plug the cable into the appropriate connectors.

The SubArc Digital Series power sources are easy to integrate by using the standard Modbus^庐 connection and different levels of integration are possible, from simple remote operation to more complex automated systems.

The improved flux delivery system uses a valve mechanism to assure continuous delivery of flux to the arc, and also provides a barrier between the flux and the actuation device to prevent jamming of the solenoid actuator due to dust and debris. A sight glass on the front of the flux hopper allows the welding operator to visually monitor the remaining flux.

Additionally, an increased environmental rating to IP-23 for all products in the SubArc Digital Series provides the high level of protection required for applications in harsh environments.
