The Pyramex Leadhead WHA200 helmet is an auto darkening helmet suitable for welding. The light state shade is #3 and it adjusts from IR shade #9-13. Made out of thermoplastic, the outer shell offers full face, neck, head and eye protection and prevents welder’s fatigue. The nylon suspension is fully adjustable to ensure wearer comfort. A superior design minimizes carbon dioxide build up but provides space for respirators if required. This auto darkening welding helmet runs on 2/AAA batteries and solar power with one sensor and it can withstand high impact hazards.
