PowerWeld offers a range of curtains designed to protect casual passers-by from harmful radiation in industrial working environments. Arcs and sparks generated from welding and grinding are harmful to the naked eye. PowerWeld 14 mil transparent vinyl welding curtains al-low those outside of the workspace protection during pe-riods of short-term visibility, dispersing the light generat-ed by the arc while allowing light back into the workspace. All curtains meet CE EN1598-2011, ensuring acceptable transparency, reflectance, IRUV protection and flame re-sistance. PLEASE NOTE: transparent vinyl welding curtains are not intended for use in place of approved eye protection for long-term viewing.
