important information!!!
Unfortunately I have to inform you that color of our AULEKTRO welding lenses is brown-green in majority.
Due to tolerances in raw material composition there can be a light blue shining in a few production cycles
 
Cobalt blue glass is mainly manufactured for infrared radiation protection and can't be used for welding purposes.
European standard EN 166 strictly aparts those two patterns of use.
 
Gold tone sputtered lenses for welding are available .
color of the glasses
all AULEKTRO glasses glint in welding brownish or greenish
they are not blue
cobalt blue glasses are there in shade din from 4 - 8  ( one shade) and are not suitable for welding (German standard)blue glasses make the eyes tired very quickly at work
 
Information from the producer:
TO WHOM IT MAY CONCERN
RE: COLOUR OF AULEKTRO WELDING GLASSES
 
Dear Sirs,
 
Please be informed that the AULEKTRO Dark Welding Protection Glasses as supplied by us
are always having a green colour. This colour is resulting from the composition of the used
raw materials and cannot be changed.
However, small differences may occur due to the production process.
