There's a popular belief that the chameleon welding mask doesn't have batteries and somehow functions without them. Even the Chinese manufacturer claims the mask functions perfectly without them. It may work, but it only protects the face, not the eyes.
In fact, it contains as many as 2 elements of the type CR2032Each of them has a voltage of 3 volts. They last for about two years of operation, after which you have to buy new ones.
You'll need the components with a yellow border and built-in pins. Next, take a soldering iron and desolder the old components. Be careful here, otherwise you could damage the circuit board. Next, solder the contacts of the new batteries into the vacated cells. This completes the battery replacement process for the Chameleon welding mask.
