To all, another 2 cents....
I too have both units. I prefer the electromelt. I like the
simplicity of the unit. Removing the crucible in the Italian model
has been difficult only when the crucible is old. I pinched the top
right off one time with the tongs provided. The top on all of the
crucibles will wear with time.
Each metal should have its own crucible. Don't use the same crucible
to melt gold and silver. Some metal will always stick to the inside
of the crucible.
I started casting in 1971. My electromelt was purchased in 1977. I
still use it. The element went out only one time I keep a spare on
hand. Parts are still easily available. This is the smaller unit and
not a digital one.
When pouring you simply press the stirring rod on the top of the
graphite crucible to keep it in place while pouring. It will never
fall out that way.
The electromelt graphite crucible is available with a flat bottom on
the inside. I think it is available from Gesswein.
Temperate is confirmed by my fluxing & stirring, not just the temp
gage. I routinely pour at 2100 which is over the temp capacity of the
unit with no problem. The deox metals all need a little more heat.
I regularly cast 150 to 200 dwt with no problems. I prefer to spin
cast smaller amounts under 100 dwt with an old HR casting machine
from 1974. The spring has been replaced on that unit once also.
I use the Italian furnace at school, but would only purchase an
electroment if needed.
