Welding burns, Alot. Yes slag burns etc. I have only had Flash Burn in the eyes 1 Time. I tell you what, it feels like 80 Grit sand paper in your eyes for about 3-4 Days. I remember 1 time I was welding at work in the summer with just a cotton shirt on, I said damn something smells weird and it is getting really hot. I finished the weld lifted my hood to find that my flippin shirt was totally on fire............my work partner was laughing his azzzzz off, luckily I didn't get hurt on that one.
