Abstract

Electro-optic filters with a transmittance variable in time are used for eye protection in electric welding applications. These filters change their luminous transmittance automatically from an initial maximum value to a minimum value when the welding arc is ignited. In the light state, the work-piece and thus the location where the electrode is to be set can be observed. After the ignition of the arc, within a certain switching time, the filter changes to its dark state in order to make the welding process visible.
