Another consideration would be flash burns.  if the arc would flash burn your eyes, welding glasses ???

I have a 6-ft tall lead-lined gobo on wheels with a lead-glass window that came out of a 1950's doctor's office when they had their own X-ray machines. No kidding. That will be my last line of defense along with a welding face shield and ear plugs. Since the idea is to keep raising the power level until something breaks, I have to assume it will be north of the product's rated 5,000 joules of spike protection which is nothing to take lightly. I'll design this thing for up to a 10,000 joule  discharge, start low, and take it up a bit at a time.

I should have made the distinction in my earlier post-the "faceshield" I mentioned was intended to be one made for arc flash-they have UV protection as well as being designed not to melt  in the event of an arc flash.  Presumaby this is a paying job-charge enough to cover the cost for the correct PPE.  It's cheaper than an ER visit.

Yes, this would be a well paying job, so I'll get the correct PPE and be super safe. I've had a few serious burns in my youth and saw a few arc-flashes from a distance, so I'm very respectful of what can go wrong with this type of experiment. Kids, don't try this at home....
