Question about Miller 903777012 SPECTRUM 2050 PLASMA CUTTER
When I turn on machine I get power and ready lite. Then 2 1/2 seconds later ready lite goes out and press alert comes on. I have correct press thru regulator to solenoid and the press switch ohms out as closed above 40 psi. Since I have two 2050s, I swapped the 4 PC boards(2 on each side) as well as the torch/hose assembly and still have same symptoms. Any suggestions as what to try next? Tom
