Passive welding helmets have a fixed shade lens, typically a #10, which does not change. The welder must flip the helmet up to see clearly when not welding and flip it down before striking an arc. These helmets are generally more affordable and durable, with fewer components that can fail. Auto-darkening welding helmets, on the other hand, have lenses that automatically adjust their shade based on the intensity of the welding arc. They remain clear or lightly tinted when not welding, allowing the welder to see clearly without flipping the helmet up. When the arc is struck, sensors detect the light and darken the lens to a pre-set or adjustable shade level. This feature provides convenience, reduces neck strain, and allows for more precise work as the welder can maintain their position and focus. In summary, passive helmets are simpler and more cost-effective, while auto-darkening helmets offer greater convenience and efficiency.
