Large Bell Jar Arc Melt Furnace MODEL ABJ - 9000 pages

Large Bell Jar Arc Melt Furnace
MODEL ABJ-900
Arc melt furnaces provide a cost saving alternative to resistance or inductance heating
furnaces for many applications. Rather than heaters or induction coils, an electric arc is used
to heat up and/or melt parts. Our Large Bell Jar Furnace can instantly reach temperatures
over 3500ºC, and will cool down to room temperature in minutes. The ABJ-900 arc melt
furnace is a large version of our ABJ-338 system. It comes with a larger chamber, larger
hearth plate, larger power supply, and can be equipped with three stingers. It is simple to
operate, extremely reliable and is economical to run. MRF will provide custom melt cavities
in the hearth plate at the customer’s request. The many available options such as load locks,
splat rod, crystal growing kit, high vacuum systems, and more make this furnace versatile
and adaptable.
