yea I copped a shock from an arc welder when I was welding in 60 degree's, my body was full of sweat and my welding glove arced. There was a small hole in my middle finger and another one in my index finger on my right arm. The quack said it was lucky I'm a left hander or I woz 1 dead baby, the quack couldn't work out why the arc went up my arm then exited at nearly the same point. Needless to say I'm 1 lucky bloke. Sure this ain't electronic related but a shock from mains power would be just as bad if not fatal.
