Gold-shade protective welding lenses are used in the same application areas as standard lenses, but are specifically for high-temperature work due to the metal coating reflecting away 90 % of the heat (compared with 4 % heat protection with the standard protective welding lenses).
Additionally the lens also allows the weld pool to be viewed more like its true colours.
Require a clear plastic anti-spatter lense on the outside and a polycarbonate lense on the inside
