The holder hsd one stationary holder and one that pivots to control the arc length. The electrodes are clamped in each holder and be adjusted for length as they burn down.

Thanks Cecil, for the link to the carbons at Walmart. There might be 
hope of getting them yet.
Only place that had them last year was in a big box quantity that cost a 
fortune and would have lasted me a
lifetime.
Keith, Gene has explained it well. Last thing I used my carbon arc torch 
on was attempting to pull a
rear brake drum on my 39 Ford. No luck yet . I use the bigger carbons, 
not sure but think they are the
half inch ones. They are the biggest that will fit in the torch holder.
I don't have any photos handy but google turned up some pictures that 
are similar to mine.
