What Is a Passive Welding Helmet?
A passive welding helmet is a safety helmet used during welding, characterized by a lens that is constantly darkened.
Welding helmets are primarily of two types: passive welding helmets and auto-darkening welding helmets. Auto-darkening helmets feature liquid crystal lenses that automatically darken in response to the intensity of the welding arc, providing a clear view in the absence of the arc and eye protection when it occurs.
Conversely, passive welding helmets have lenses that are permanently tinted to a dark shade (typically around shade #10), offering consistent darkness regardless of the welding arc’s brightness.While passive welding helmets may offer less operational flexibility than auto-darkening helmets, they remain popular due to their simplicity, lightweight design, and affordability.
