The heat from welding well I suppose it could if you were very careless.

Separate comments, separated by the "..." comment #1: lots of welding masks are safe for viewing the eclipse... Which is 100% true. Comment #2: The arc of a weld is actually hotter than the surface of the sun. Also, 100% true.

Followed by the "I believe the mask/goggles with shades 13 or higher are sufficient for viewing." Which takes care of the luminosity part of this.

The temp comment was a fun fact. I think it's pretty interesting.
