Auto-darkening provides excellent protection, and also improves welding performance.
Before welding, auto-darkening welding helmet helps welders to see their work at comfortable light levels with constant eye and face protection. It turns dark the instant an arc is struck and become semitransparent again when welding stops. This semi-transparency works while also providing full ultraviolet and infrared protection at all times, which are in accordance with various safety regulations for welding safety standards.

Applications that require small, frequent welds can realize significant benefits in both productivity and accuracy with the use of auto-darkening helmets. This gives maximum protection in both low voltage TIG and out position welding.

Auto-darkening technology also reduces the neck strain associated with “helmet nodding.” In theory, this should help to increase the accuracy of electrode placement because the welder does not have to raise the helmet to get a closer look at the weld in progress. This, in turn, possibly reduces the need for grinding and rework.
