I never had any lessons of welding or whatever. I even had not worked with metal before I begun to restorate my bug. I only ones had got an little shock. And that was only an dump fault of mine. I just had cooled some welding with water and emmidiately welded after that. That wasn't smart.
But of the rest I haven't ever got any shock.

p.s. Don't be stupid to weld without any weldingmask
