Automatic Welding Mask Auto-darkening Welding Helmet

An automatic welding mask (auto-darkening welding helmet) protects the welder's eyes and face by automatically changing the lens from a light shade to a dark shade when a welding arc is struck. This allows you to see the workpiece clearly before welding and eliminates the need to flip the helmet up and down. Key Features to Look For Auto-darkening filter (ADF) with fast switching speed (typically 1/5,000 to 1/25,000 second) Variable shade control (DIN 9–13) for MIG, TIG, and ARC welding Grinding mode for use as a face shield during grinding Solar-powered with battery backup Adjustable sensitivity and delay controls Large viewing area for better visibility UV/IR protection even when the lens is in the light state .
