Features

Miller's SubArc AC/DC Digital
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 thick weldments without compromising quality.
All AC balance control modes can be set
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.
Easy-to-understand interface
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.
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.
Simple tandem setup
To use two or more AC arcs, the arc must be phase shifted to prevent arc to arc interaction. This is simply done by connecting the tandem cable from from the first unit to the second unit. This automatically sets the optimum phase shift for AC welding. No special tools, laptop or software needed... plug and play.
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.
