Carbon Arc Troupers

I suppose IF one operated the carbon-arc fixture with the lamphouse door open, which would require defeating the safety switch, one would be exposed to more UV radiation than other arc sources, as there would be no glass to filter it.

Safety switch? Yours had safety switches?

Just like a refrigerator! Open the door, worklight comes on (and power to the arc goes off); close the door, worklight goes off (arc power restored). Except you can prove it by looking through the welder's glass window in the door.

I did develope an "Arc Burn" on my left wrist from operating a CA Super. Seems there was a slight gap between the door and frame of the reflector chamber, it shone a tiny beam of light right on the crease of my left wrist. After that I always wore gloves.
I still think the fixtures are useful. If you strike an Arc, hold it for 5 seconds, kill the power and then open the door the carbons are sufficiently hot enough to light a cigarette.

Maybe on them there new-fangled things, but all my switch did was turn the bulb on and off!

Have to use main power to kill the arc! (we used to open the doors all the time )

Except for the crude red markings!

My memory could be wrong, or I might be getting Trouper and Super Trouper mixed up. I would have sworn the door switch killed the arc power. After all, I just ran one of these 16 years ago. Of course it's always best absolutely required, to:

Remove [LOTO] ALL Sources of Energy before Opening ANY Electrical Enclosure!

JD, you should state that the drawing comes from page 13 of Instructions for Equipment Type Super Trouper 19601-4, 49006-5, 51001-2; October, 1971. It's also possible the fixtures I've used recently were newer models with additional safety features. I think you should buy the ones on auction to check for me.

Oldschool, I hope the ones you had went to a good home. I just found this, if anyone is near northern Florida and has $26 to spare.
