and within the usage  conditions given in the  Technical 
Specications.

immediately and inspect the welding lter as described 
in  these  instructions.  Continued  use  of  a  welding  lter 
that fails to switch to the dark state may cause temporary 
vision  loss.  If  the  problem  cannot  be  identied  and 
corrected,  do  not  use  the  welding  lter,  contact  your 
supervisor, distributor or 3M for assistance. 
 Use of this  product in applications  outside its intended 
use,  such  as  laser  welding/cutting,  may  result  in
