      The air solenoid comes in as soon as you turn the switch on. air is coming out of the torch as soon as you cut the machine on. No trigger pressed. The button under the trigger is not stuck. The solenoid is not stuck. It comes on as soon as you plug it into the circuit board.

        Double check consumables. Check air pressure from compressor as well.

          Consumables are new. Cap on tight. No trouble lights on. It worked fine, next day nothing.
          Local miller tech guy thinks the circuit board is done.
