5 THINGS TO CONSIDER WHEN SELECTING AN
AUTO-DARKENING WELDING HELMET

• There are two types of lens styles when it comes
  to welding helmets passive lenses and auto
  darkening welding helmets. The conventional
  welding hood is a passive lens helmet. Indeed,
  for those who haven't accomplished much welding,
  this could be the only type of helmet that
  immediately comes to your mind. That's because
  this type of helmet has a lens with a securely
  tinted fixed shade that filters out UV and
  infrared light. As a result, the lens can only be
  seen when it's turned on and the person is
  welding. Because this tint is much darker than is
  necessary, the welder often has to flip up the
  helmet's face shield in order to see what he's
  doing.

• auto darkening welding helmets are different
  because they automatically adjust their shades
  based on the intensity of the light around you.
  They do this by using infrared sensors within the
  helmet to determine when a person wearing the
  helmet is engaged in welding. When this occurs,
  the sensors signal the built-in circuitry to
  adjust the shade of the helmet accordingly.
