I have a old American Optical sure-guard flip up welding helmet that I would like to make a auto darkening but i don't know if they make AD lenses that are thin enough tho fit in the little slot for the lens or if I need to replace the plastic part that holds the lenses. I am hoping someone has some knowledge on what I should do.
And it did not have a weld-cool filter plate
