Easier setup and operation.
The improved user interface of the Subarc AC/DC makes setting up and operating the power source relatively simple. The operator is presented only
with the necessary functions to set process and control output.

AC balance is set using a rotary switch mounted on the front control panel. There is no need for a laptop PC connection to do complex wave shaping before operating. In multiple arc configurations, the power source interface control does the phase shifting for you.

Easily change the amount of electrode positive and electrode negative polarity from the front control panel of the power source.

Greater control of deposition, penetration, and heat input.
Miller SAW solutions are designed to deposit large amounts of filler material and achieve deep penetration on thick or large surface area weldments.

Enhanced distortion control.
The AC output of the Subarc AC/DC enhances user control of heat input into the weldment,
minimizing distortion, and reducing structural or fit-up problems during or after final assembly.

Multi-arc capable. 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 further increases deposition rate, resulting in shorter welding cycles for very thick weldments without compromising quality.

AC or DC operation provides versatility and outstanding arc performance.

Part of a customized system.
Miller power sources and system components enable users to implement a customized SAW solution that best fits their operations when combined with the travel and manipulation equipment they prefer.
