How does a welding helmet work?
A welding helmet is a type of headgear worn while welding to protect the eyes, face, and neck from sparks, intense light, and heat. The welding helmet’s face shield, made of a high-density plastic and darkened glass, is designed to protect the welder from the intense light created by an electric arc. It also shields the face and neck from flying sparks and molten metal.
When welding, the electric arc is created by the welding current and the helmet’s face shield darkens to protect the welder from the high levels of light. The face shield also has a filter lens, which helps to reduce the amount of ultraviolet and infrared light that passes through. In some helmets, the lens also has a special auto-darkening feature that darkens the lens automatically when the electric arc is created.
In some cases, the welding helmet may flash when the electric arc is created. This is the result of the helmet’s auto-darkening feature, which works to protect the welder from the intense light. The flash is typically very brief and is not harmful to the welder. It is simply an indication that the helmet is working to protect the welder from the light.
What are the common causes of a welding helmet flashing?
