Thread: Backlight in auto helmet??

Any ideas how to keep ambient light out of an auto darkeing helmet? Mine is one of the helmets on special at BOC. It works a treat, good sensitivity, not heavy, nice shade of darkening so that you can see the weld pool. But, when I'm welding outside the shed (keeps SWMBO happier - not so much mess, you see) there is too much daylight inside the helmet. When the lens darkens, the back light frequently overpowers the view of the pool. This will be an increasing problem because I do have quite a few outside repair and fix jobs on the list. I have tried to block out the light with a reversed peaked cap, a bucket hat, all to no avail. I've even thought of trying to rig up an arrangement with a towel, but then we run into overheating and fire risks. Any ideas?
