Larry, I cannot count the number of times that I have been laying on my back under a car....often in the dirt....with a plasma torch in my hand......and tried cutting then realized the work clamp was laying on the ground next to me. Maybe I'm a little lucky....but I have not been zapped by it. I have actually finished cutting a few bolts off with the pilot arc....which is a path from electrode to nozzle....which finds its way back to the power supply via the + cable in the torch leads.....I suspect there still is some voltage on the car when this happens....but must be low enough so you cannot feel it.
