Review on Flaming Industrial Power & Hand Tools: Welding Powered Darkening with Adjustable Functionality by Josh Jeffries

Automatic dimming? Technically yes, but the lens does not completely darken across the entire lens. Today I welded it for the first time and now I have flash because the lens is not working properly. This is a very dangerous item to sell. If I keep using it (of course not because I'm not stupid) I'll go blind. Terrible, terrible, terrible product.
