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.
