Welding the Solar Eclipse

I didn't even know they made welding goggles or lenses with ratings like 12 or 14! In the "real world" what would they be used for?

Best bet... watch the eclipse on the web or on TV.

Yea. I didn't either.
The internet says most helmets come with 10.
14 just sits on the shelf.
My welding supply said today that he could have sold 400 if he had them.
I'm not worried about too dark.
Why won't stacking work?
I'll be "at work" anyway.
