A helmet with 2 sensors is sufficient for simple work, but MIG welding requires helmets with more sensors. Getting a helmet with over 3 sensors will ensure accurate measurements, especially when dealing with various lights within the vicinity. The sensors measure the light in the surrounding. Most welding helmets come with fitted arc sensors within a range of 2 to 4. The more advanced and robust lenses have a reaction time estimated above 1/20,000 seconds. For a simple lens shade, the reaction time is estimated to be about 1/3,600 seconds. Lens reaction time is the duration taken by the lens to switch from regular to protective shade.
