im incorporating a millermatic 251 into a orbital welder with a user interface. I need a method to control the wire feed rate and current remotely. id rather not install 2 servo motor on the hand dials on the miller. does anyone know of a way to take over the control of these functions using the spool gun plug. or does anyone have a wiring diagram of a millermatic 251.
