Miller Electric Mfg. LLC introduced a new SubArc digital converter for field applications, including above-ground storage tank construction, shipbuilding and bridge construction. The converter enables the use of digital SAW accessories, such as the 3-wheel tractor and digital control, with expanded equipment including Big Blue welder/generators and Dimension 650 welding power sources. Enhanced digital communication allows for more consistent steady-state welding, improved arc starts on a range of wire diameters and increased arc stability with specialty alloys. Operators can also ensure that the voltage set at the controller is the voltage at the arc by connecting an optional voltage sense lead to the converter.
