Auto-darkening Ultrashade® welding helmets offer a sleek new design with eye-catching graphics that allow welding operators to sport a great look without sacrificing quality or safety. Auto-darkening helmets are excellent for beginners and experienced professionals because they eliminate the need to lower or lift the helmet at the start or stop of the weld. As a welding arc is detected, these helmets automatically darken to the correct level of shade protection within a fraction of a millisecond.
