Miller SubArc AC/DC 1000 Digital

Miller SubArc AC/DC 1000 Digital Submerged Arc Weling Machine

Top Features

  • 1000 A at 44 V, 100% Duty Cycle
  • Digital Process Control Technology
  • Highly Reliable Thyristor Power Regulation
  • Processes: Submerged Arc (SAW), Electroslag (ESW)

AC welding output enables the SubArc AC/DC to be used in tandem arc welding systems with a DC lead arc and AC trailing arc, or with AC / AC arc combinations. Using multiple arcs increases deposition rate, resulting in shorter welding cycles for very thick weldments without compromising quality.

Additional Features

All AC balance control modes can be set on the SubArc Interface Digital. The easy-to-understand interface includes two DC modes and 12 best-practice AC balance settings. In multiple-arc configurations, the system automatically adjusts the phase shifting between power sources thereby eliminating arc interaction. There is no need to employ a laptop PC for complex wave shaping before operation.

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. The easy-to understand interface provides the operator with the necessary controls to set process parameters and control output. The power sources feature simplified parallel and tandem setups — just plug the cable into the appropriate connectors.

Easy to Integrate
Easy to integrate by using a standard Modbus connection with different levels of integration possible, from simple remote operation to more complex automated systems.

Low-Voltage Accessory Operation and Improved Environmental Protection
The 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.
