Air Fed Welding Helmets (also called PAPR welding helmets, short for Powered Air-Purifying Respirators) are advanced welding masks that combine face protection with a built-in respiratory system. They provide clean, filtered air to the welder while shielding eyes and skin from sparks, UV/IR rays, and spatter. https://www.hampdon.com.au/saf....ety/welding/helmets/
