•   Liquid crystal  of  high  quality ,optical coating,and  protection for sheilding  ultraviolet  and  infrared  rays  are adopted  to protect  welding  operator  from  being  injured  by  harmful  rays  such  as  ultraviolet rays ,infrared  rays .etc.
• Liquid   crystal  light  valve  adpots  the brand new techonology of automatically changing  the light  controlled  by  light .multilayer LCD and coated  glass effectively stop  ultraviolet  and infrared  rays  and  let  the visible light  through easily  so  as  to protect  the eyes of  the operator, and  enable  him  to  observe  welding  object  clealy ,thus reducing  repeaed  welding,and improve  efficiency.
• The   original  design  of automatic   transform  technology  used  in controlling  circuit  make  it possible  for  goggles to  be able  to react to the arc  in 1/10000  second  and  change strong  light  to  dark light . AS  a result ,  it can protect our eyes form being  injured  by  sudden  arc.
• The original  design   fo Anti-interference switch  avoids not  seeing  welding  object  clearly   due to complex  surroundings nearby.
•  The Time of  goggles' changing  dark  light  to strong   light  when  arc  disappears can  be set  within  0.1 second  or  0.8 seconds  as  required.
• CE EN379 industrial  welding cap   goggles with  function  of setting  levels  manually   can  be  divided   into  two levels:one  is  light   shade---DIN4 ,and   the other  dark  state--DIN9~DIN13.
