[nick91a]

Miller dynasty 200 has no weld output machine turns on and can toggle through all settings ? Anyone have any idea ? Ac Dc , lift arc , high frequency, stick …. Nothing no arc

Start with the output inverter board and connections to and from it. Follow the pre-power checks in the technical manual (google for it; miller won't provide it). Beware high voltage.
