Specifically, is an electronic welding helmet safe to look at the sun?

Short answer, I wouldn't try it.
Take a cardboard box, put a pinhole in it (aka pinhole camera), and aim the hole at the sun. Put a sheet of white paper below the hole so that the sunlight beam coming through the hole shines on the paper. Move the the sheet of paper farther away from or closer to the hole to set the image size. Enjoy the view. No danger in doing that. |
