Welding to bright for CCD?

I love this kinda threads. The only advice I offer in this one is listen to the guys that do that job everyday.

Last week I was doing a timelapse of clouds over a Cape Cod beach. The clouds were dissipating and I realized the sun would soon be shining into the lens. I had the manual with me and read on p. 124: "Do not point the lens or viewfinder at the sun. Doing so may damage the parts inside," so I stopped the timelapse early (which I now realize I didn't have to do). No real point to this post-- just seconding David's appreciation of the useful information provided here.
 
I was a welder for 9 years before I committed fully to film and video production work. All I can say is try not to look at the light for a long period of time. Looking through the viewfinder is fine, because it is a digital representation of what you are seeing. Most of the UV and inferred light are taken out before it hits your eye. But watch out for the other eye. Even if you other eye is closed, the harmful rays will penetrate your eyelid. I learned the hard way, and spent a few day in the hospital with arcflash from my first welding job. Also the light can give you a nasty deep sunburn, so wear long sleeves and pants.
 
I was shooting a lightsaber fight awhile ago, and man, I guess Jedi don't get sunburned, cuz afterwards, whoo! I had to buy about a gallon of aloe vera...
