Miller Electric Manufacturing Co. has created the new Performance Series line of helmets. The Performance Series is designed for professional and production welders, and features three arc sensors that darken the lens between shade #813 in 1/20,000 of a second. The Performance line also has an Auto-On/Auto-Off feature, which activates the lens shade without having to manually turn the helmet on, and grind mode, which stops the lens from darkening while grinding. New features also include a magnifying lens holder and a quick-release front lens cover.
