From what I read, not all welding helmets are safe for viewing. Please check a responsible website to ensure yours meet the criteria.I will use my welding helmet. Got a shade 11. Shade 12 is too dark. Shade 10 too bright. I also got a plain shade 11 lens incase the auto lens in my helmet doesn't kick on-we are in the north east so don't think we will be in line of sight but I will pop outside Monday and see if we see anything.
