Auto-Darkening Filter (ADF) is a laminate of
seven different layers: a UV/IR filter, three polarizers, two liquid
crystal elements and a cover glass. The UV/IR filter continually
blocks harmful radiation, whether the filter is ON, OFF, light or
dark. Aided by surface-mounted electronics, the proprietary liquid
crystal elements act as shutters that detect and react to the welding
arc by instantly shading the filter. Meets ANSI Z87.1-2003
American National Standard Institute for eye and face protection.

Note: Because faceshields and welding shields can be raised from
the normal position, ANSI Z87.1-2003 states that safety spectacles
or goggles must be used in conjunction with these respirators.

Filters turn dark
the moment an arc is struck and transparent again when welding stops–
all the time with full UV/IR protection.
Auto-darkening eliminates the neck-strain of “helmet nodding” while
helping increase the accuracy of electrode placement.
This, in turn, helps reduce the need for grinding and rework. In
addition, welders can get into tight, cramped spaces with full
protection and have a clear view, making extremely awkward welds a
lot easier.
Constant UV/IR Protection:
This filter provides the same UV/IR filtration protection as a traditional,
non-auto-darkening welding filter (as regulated by USA and Canadian welding
safety standards).
