Auto Darkening Filter
The GVS ADF is an automatic welding filter is a device that protects the eyes from glare and dangerous radiation caused by welding.
An automatic welding filter combines a passive UV and a passive IR filter with an active filter, the luminous transmittance of which varies in the visible region of the spectrum, depending on the irradiance from the welding arc. The luminous transmittance of the automatic welding filter has an initial high value (light state).
After the welding arc strikes and within a defined switching time, the luminous transmittance of the filter changes to a low value (dark state).
