FEATURES The VIPER Welding Helmet is equipped with an automatic darkening filter. The filter is transparent before welding so that the operator may observe the work surface clearly. When striking arc, the filter darkens automatically immediately. When arc goes out, the filter will become transparent again. The switching time from light to dark is about 0.1 ms.
THE POWER SUPPLY The power of the VIPER Welding Helmet is provided by solar cells. Turning on or off is automatically controlled by the circuit. You can use this helmet at any time you need and take it away after working without operating any key.
