Automatic Darkening Welding Helmet

A welding helmet with auto-darkening protects the retina from glare and UV light by darkening within milliseconds when the arc ignites.

Physical-Chemical Mechanism of Action

The auto-darkening welding helmet contains an electro-optical filter. This filter reacts to the intensity of the arc and darkens in milliseconds to block harmful radiation.

Metallurgical Relevance & Risks in Welding

The darkening protects against acute damage to the retina from intense arc radiation and UV light. Without such protection, the retina can be damaged, leading to discomfort or long-term health issues.

Workshop Practice & Instructions

Use the helmet for every arc welding job. Ensure the filter works correctly and can darken within milliseconds. Regularly check the battery and light sensors of the helmet.
