Karoline, I do think that you missed the point of the link. I referenced that site because it showed a link to Ultra Violet radiation and the symptoms that others have been having. Obviously people who weld should wear substantial protective clothing when welding. Gauntlets and thick over garments as well as a full head helmet that protects the throat and neck should be worn. Ultra Violet rays pass through many types of cloths so protective clothing has to be chosen carefully.

With reference to that site. Maybe I should look a little better at what the site is before I link it. But it also shows that there are also benefits to UV rays as well.

Mike.
