It features 4 arc sensors and an BIG viewing area of 3.78 in. x 2.09 in. This unit features our Opticlear 2.5 lens technology for a lighter light state and clearer colors while welding. Adjust your shade control from 9 to 13 or put it in Grind mode to prevent darkening while grinding. Made to fit right, it features an adjustable headgear to allow you to make it fit your way. With ANSI and CSA approval, the Metal Man 8735SGC Series Auto-Darkening helmet is safe, functional, and attractive to users.Zoro #: G9177825Mfr #:AOC8735SGCThis item has been restricted from sale in the following states: No
