you will need to cover the sensors then give them a flash to the light source to make the helmet change best done with the sun, if we get any.

Does your helmets batteries have charge?  And make sure it's switched on, as mine switches off after 10 minutes or so of not being used. I'd test it by putting it on and arcing up the welder but having it so the masks sensors can see the arc but you can't,  so you'll then see if it works. Who made it anyway, the speedglas ones are good, about the most common in industry.
