| 342365 | 2005-04-14 02:35:00 | Why not use something which is designed for eye protection.? An arc welding filter at $2.40 is cheap enough, surely. | Graham L (2) | ||

Graham, you are wise in your insistence on the right protection and a light hearted suggestion such a a floppy innard is probably not appopriate. BUT how do we know that arc welding glass designed specifically for that purpose does not allow transmission of something in the sun that could be harmful? |

Nothing will. So we have to accept them. It will attenuate the UV, visible, and IR to a safe level. They are the harmful "somethings" which we can do something about. I have had "arc flash" a couple of times. I am careful, but it happens. That's nastier than looking at the sun. It's closer.;) But a mask with one of these filters lets me watch the arc for a fairly long period. |
