Auto-Darkening Filter (ADF): The lens uses light sensors to detect the welding arc and instantly darkens (within milliseconds), protecting the eyes from harmful UV and IR radiation.
Adjustable Shade Levels: Typically ranges from shade 9 to 13, allowing the user to select the appropriate darkness for different welding processes like MIG, TIG, or arc welding.
Fast Switching Speed: High-quality helmets switch from light to dark in as fast as 1/25,000 of a second, reducing eye strain and risk of arc flash.
Sensitivity & Delay Controls: Users can adjust how sensitive the helmet is to light and how long it stays dark after welding stops.
Large Viewing Area: Provides a clear and wide field of vision for better accuracy and comfort during welding.
Power Supply: Usually powered by solar cells with backup replaceable batteries
