I have a Miller 210, put 1 spool of wire through it and it always worked great. I moved from California to Colorado 3 years ago and just now was able to use welder. I plugged it in and turned on the switch and........ nothing! I checked the power source and then opened up the welder. There is power to the switch and out the other side. There is power to the fan and the leads going to the transformers but nothing comes on..... Any ideas???? Help!
