I have my plasma cutter, control cabinet, and table connected to an 8 foot ground rod about a foot away from the table. The PC is plugged into a surge suppressor outlet strip. Should the PC case be connected to the table ground?
The machine worked fine when I turned it off. Now I find the PC is fried (won't boot), the four buffer chips on my C10 breakout board are fried, and one of my stepper drivers is cooked. We had some severe lightening storms, and we also did some TIG welding in the shop. The TIG machine is only grounded through it's power cord. I don't know if it was the lightening or the TIG, but I'm betting it was the TIG.
And that brings me to another question. Can I use the same ground rod for the plasma and the TIG?
