Hello to all;new to the forums;and only welding 5 months or so in a school enviroent.I have been through a slew of hoods,and lenses.I had an instructor who had the "cool weld" lens,and it was great,but I can't see spending 300$ on a 2x4 inch peice of glass;all my searching led me to Phillips Safety.let me tell you,these lenses are the best lenses I have used in my short time;and every time a guy in the shop uses my hood;they want one.2.50$ per lens.....just wanted to get the word out,these lenses are about as clear as it gets in my opinion.....anyone else use them?
