How is this possible?
Convective heat transfer is dependent on time. His contact with the molten metal only lasts for an extremely short time.
Yep... what Bayard said.... When I was a pipefitter on submarines, used to watch electricians draw a spark with their fingertip from high voltage lines.... negligible current, so no damage - well, except for a tiny pinprick black spot on their finger. Cheers, RickO
Still... no thanks. I like my fingers.
