Can someone help me, I have a 3.5 year old Hypertherm 1000 with a machine torch. Awhile back the torch safty switch would not work, it stayed in the open mode and no red light when consumables changed. I posted this problem and Jim told me to clean the micro switch, problem fixed. That was over a year ago. Now within the last month I have to tighten the retaining cap very tight to get the yellow light to go off. I know they recommend not to over tighten this cap but it is the only way I can operate. I took everything apart to clean and found no build up, the small mico switch worked freely. Tried new retaining cap and consumables, but same result. Wonder where I should look next. THANKS,,,,,,CURLY
