stupid me looked at welding for a second

I'm a pipefitter, and was holding a piece of Stainless Steel as my welder was tacking it. Tig welding. Didn't have my gloves on, and was holding the piece with my bare hands. Got hot, flinched and got zapped(my hands were shielding my eyes). Split second, not long at all. My god, my eyes have never hurt like that before. I couldn't sleep it was so bad.

Tig welding is the worst for brightness. It's about 10 times as bright as a regular arc welder.

But it does go away. No lasting effects.
