That 2000F is a max, the thing uses nichrome elements which fail
above 2000. Maybe they have swittched to a higher temp wire since
I toasted one a few decades back. No superheat possible and a 1%
error in the controler and you have a dead unit.
Wonder if you could use a Kanthal A1 in that to soup it up a bit?
You’d have to do the calculations of course, otherwise you can have
some unexpected fun.
I burnt out an enameling kiln (very easy to do if you put the wrong
stuff in it
). I threw in a length of Kanthal A1 just to see
what would happen (I was very bored that day). A very interesting
result. Heated up the room for a very short time before I melted the
wire.
It would also depend on the failure temperature of the refractory in
the unit.
