I enjoyed what you wrote. Years ago I worked for a small town newspaper. They used old technology to make offset plates on site and the paper was printed elsewhere. The setup they had used a "copy camera" that used two large carbon arc lights as a light source. The exposures needed were a couple of minutes. In that room, the brightness was incredible and the whole building heated up very quickly. Not bad in the Winter, but awful in the Summer.
The electrodes were at least 1/2" in diameter and I think they were about a foot long when new. About every other exposure, the electrodes had to be adjusted so they were the right distance apart as they were consumed. They also smoked and sometimes popped out sparks. Probably not the safest job I ever had!
I have read about carbon arc torches in welding books I have read, but never have come across a torch for sale. I asked at a welding supply shop, but they didn't know what I was talking about. I will keep looking. Interesting post!
