The visor has adjustable darkness level, adjustable sensitivity to the intensity of the light source, as well as adjustable time for maintaining the dark state after welding. A button on the outer shell in the grind setting disables the dimming function. The helmet can then be used as a means of personal protection against, for example, sparks from cutting or grinding metal. The four-point harness, thrusters, size adjustment system and working angles allow the helmet's position to be adapted to individual requirements and working comfort.
The filters have a TEST button to check the operation of the self-dimming function. A routine of checking the filter every time will help protect the operator's eyes and health.
