Welding Helmet – Key Features To Look For

Welding helmet is a protective gear which should be used by every person to protect the face and neck while doing welding. Welding helmets protect you from sparkling ultraviolet light produced in welding which is capable of damaging your eyes, face from flash burns, igniting sparks, and excessive heat evolved during welding. Welding wolf is a site which provides valuable information related to welding helmets. Welding helmets have many characteristics, some of them are mentioned below:

  • Auto darkening: Auto darkening feature is very popular in welding helmets. Auto darkening helmets are equipped with high quality lens that is very sensitive to light. This auto darkening lens doesn’t get dark until and unless a weld arc is struck. These helmets have a built in sensor which automatically detects the amount of light being emitted during welding and darkens the lens accordingly. This darkening of lens actually happens in milliseconds after the light is being emitted. When the welding is done it automatically resets back to its normal shade giving you the look of sunglasses. Auto darkening welding helmets provide effective protection against the ultraviolet and infrared rays emitted during welding.
  • Fixed or variable lens: Generally, welding helmets come with fixed darkening lens that offer fixed amount of automatic darkening. Variable darkening helmets vary with many of the welders. A variable darkening helmet offers different amount of darkening levels to choose from. Variable darkening lens automatically darkens according to the intensity of light being emitted. Greater the light being emitted, darker the lens will be. If the less light is being emitted, the lens will be less dark providing you the perfect low darkness required for seeing the things as they happen.

Protective lens: These protective lenses are usually cheap and work as a protective layer before the main welding lens. These lenses bear all the wear and tear caused during the welding. Protective lenses do become opaque, scratched, and damaged from welding sparks. As a result protective lens need to be changed from time to time for better visibility.
