Marc,
We have been replacing just about every part on the machine, first they go out for a bad pc board, then the water cooler pump fails, then we get it back in and another board goes bad. I can't tell you how frustrating this is getting. We go down for about two hours every time we lose a power supply, and everyone is getting very fed up with this. We need to get something done about this, every time I contact Lincoln they say that it our fault that we do not PM the machines correctly. Well there suggestion for PM is to clean and check the power supply every six months, but they only last three months. They have no answer for me as to why this is happening. I have considered other power sources, but haven't been able to find much information on which power sources interface with fanucs controllers directly.
Let it Snow,
Josh
