Expanded Fleet Capability The new SubArc Digital Converter enables
Big Blue welder/generators and Dimension power sources to power digital SubArc accessories.
Optimal Welds Enhanced digital communi cation allows for more consistent steady- state welding, improved arc starts
on a wide range of wire diameters, and increased arc stability with specialty alloys. Ensure the voltage set at the controller is the voltage at the arc by connecting an optional voltage sense lead to the SubArc Digital Converter.
Seamless Integration, Simple Setup As one all-inclusive solution, the Miller SubArc Digital
system is simple to set up, so operators of varying experience can easily connect their SubArc accessories to Miller power sources for streamlined field operations.
