The Sherman-profi V3b automatic welding helmet is designed to protect eyes and face from sparks, chips and harmful radiation during welding and grinding. 

The automatic blackout filter automatically changes from bright to dark after ignition of the arc and becomes bright again after welding.
The helmet has two external knobs that allow you to adjust the degree of darkness from 9 to 13 according to DIN and smoothly adjusts the sensitivity of photosensors' response to arc intensity during welding, as well as two external switches that allow three-position adjustment of the dark / light switching delay time and change of operating mode. The blackout filter ensures full welder safety. It is equipped with four photosensors, which is especially important when welding with low currents. 
The V3b helmet has an extremely advanced, comfortable and ergonomic headrest for perfect fit and full adjustment of the helmet. A special tilting system changes the visor's center of gravity relative to the welder's head.
After selecting the grinding function on the internal control panel, the blackout filter switches to bright without darkness adjustment
