    I have the casting machine is a Thermitrol#3 for 25 years. There are
    the sling arm, the base with the casting spring and electric
    contacts, The temperature electric eye control and a Rheostat to
    adjust the amps while casting. Did you get the Factory Manual with it.
    I takes carbon crucibles that come out, so you can cast different
    types of metal with out getting the metal mixed up. 

    The crucibles are expensive but last quite a whils. There is a Carbon
    flux they recommend to put onto the metal before casting. DON'T USE
    ANO OTHER FLUX AS IT WILL RUIN THE MACHINE. The spring that runs
    thecentrifuge broke last year and I got a replacement spring from
    Frea & Borel of Frisco. I had it put back in the housing by a company
    in Colo Spgs Colo. Called the Jewelry Doctor. He did a great job and
    my unit is runing great. The caster was quite expensive when I got
    it. The Muffel Heating unit cost 2 or 3 hundred several years ago as
    a traid in replacement. Hope this helps My I -3 will cast 20 oz of
    gold or 15 oz of silver and you just set the temp on the dial and it
    buzes ahen the metal has reached the temp you set it for. 

Yours
