ABSTRACT:
A curtain for surrounding welding and cutting operations, especially electric arc welding and electric arc cutting operations to protect the eyes of otherwise unprotected observers such as supervisors, adjacent workers, and visitors to the welding operation. The curtain contains dyes for the purpose of absorbing radiation of wavelengths of potential hazard to such eyes. Because no dye can absorb all potentially harmful radiation and still provide some visibility, means is provided to improve the protection by means of reducing the exposure of the retina to undesirable intensities by optically enlarging the small arc spot, and by presenting the eye with general area illumination instead of pinpoint illumination.
