Solar powered auto-darkening helmets have both solar and battery generated power. The battery is used to initially power the mask or hood while you get the welding arc started.

Solution : Replace Battery Usually, a flickering side sensor light or a shaky auto darkening filter just means you need to replace the batteries in your welding helmet. Of course, if your helmet doesn't have replaceable batteries, then this problem most likely means you're due for purchasing a new welding helmet.
Usually, the batteries can be found through the front of the casing. If you examine the front casing section near the lens you should be able to find a solar cell. Once you locate this area, use your Dremel tool to dissect the battery.
