Abstract

A welding helmet (100, 200, 300, 400, 500) having a filter arrangement is disclosed. The welding helmet is provided with a main filter (102, 202, 302, 402, 502) and at least one auxiliary filter (104, 204, 304, 404, 504) separate from and positioned next to the main filter. The at least one auxiliary filter comprises an electro - optic element (10, 20) adapted to attenuate the transmission of optical radiation incident on the auxiliary filter.
