Ack, so much for getting this thing tested before my return window runs out. *grin*
Mark, I have some cinderblocks I can prop it on. I would not fire it up on cement either. Good reminder! I was hoping I could at least plug it in and test out the panel, but neilestrick is talking about a center tap transformer and I have no idea about that. Ack. And a thermocouple. We run our plasma torch off the 220 in the shop and the lift for the cars, but that's all I know about the electrics. The unit came with a standard plug running from the unit, and an additional cable which matches the plug in our 220 transformer, but may not be what I really need?
Here are photos of the unit just in case anyone has some other information I could use to figure out how to test this sucker. Thanks for the responses!
