Richard,
Copper mantled carbon rods from welding store do not work. I tryed it.
Iīv got 30 cored carbon rods Le Carbonne brand, 12, 14 and 18 mm dia,
length 250 mm, and I recon that a pair of rods will last about 4 hours
of burning time. I am still looking to buy more rods. I found a
company in USA which makes them but I didnīt have time to contact them
and ask for details: http://wwww.nationalspecialties.com/
My antique carbon arc light is an open fixture and lightens
horisontaly so a have to tilt my vacum frame verticaly. It is conected
over the transformer 220V to 45 V AC, 40 Amp. The transformer is very
havy and today I donīt understand how I put it in the place.
To teach my grand children about darkroom dangers I turned that light
on in their presence and humming from the arc and the transformer
plus that strong light scared them enough not to touch the darkroom
door without me.
The light is very strong and consistent, no warm up time. I use it
occasionaly for exposing of photogravure tissue. Seven minutes at
0,8 m distance. No, I donīt look in the arc, and I donīlike to look
in the sun either. The switch is five meters from the light, I donīt
see the arc, I just leave the room when exposing.
Kemal
