That is cool, MT! My bifocals under my helmet are not fun. Can only see the work by looking down and it makes for just another difficulty. (like my teaching my self to weld is not enough)
My cheapo, self darkening helmet from HF amazed me and I was sure it couldn't work. Honestly, how could it darken enough to protect eyes when the arc light is moving at the speed of light?
Just amazes me!
I was gonna say we should invent a solar powered, auto darkening welding helmet and get filthy rich. But then googled it; https://www.google.com/search?q=sola...sm=93&ie=UTF-8
