I've go an AD hood but I still and always have done 'blind tacks' when felt like it......All of a sudden I'm less inclined to continue that practice. Thanks for the post and get well soon!
30 or so years ago I did so much blind tacking in one day I burnt my eyelids, that was an eye opener......Also around the same time I laid down allot metal with a wire feed one day wearing a tank top.....Burnt my armpits real good, I don't recommend it.......
Knew a fellow back in the 70's who was a structural welder. He welded all day long in the hot sun on the top floors of buildings and didn't even wear a shirt, just hood,jeans and boots.......He had a very dark leathery tan on his upper body, bet he's dead from skin cancer now.
