The Sherman-profi V2a 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 light to dark after ignition of the arc and becomes bright again after welding.
The V2a helmet has two external knobs enabling adjustment of the shade level from 9 to 13 according to DIN and smooth adjustment of sensitivity of photosensors to the intensity of the arc during welding. On the internal control panel there are two switches that allow three-position adjustment of the switching delay time dark / light and change the operating mode, as well as the button? TEST? allowing to check the correct operation of the helmet's automation. The blackout filter is equipped with four photosensors, which is especially important when welding with low currents.
The V2a helmet has an 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, the blackout filter switches to bright without darkness adjustment.
