Welding Helmets
I have a Holbert Hood, I picked up cheap $20 at Tractor Supply, it was mis-priced, it is solar powered and works good for as little as I use it.
One time last winter I struck a arc, and the battery was not charged, you will notice that fast.
The helmet is a huge improvement over the old flip hood I had.
I have had both my eyes bandaged from flash burns in the past, it hurts like hell, you only have one set of eyes, take care of them.
