ARC MELT/ BELL JAR FURNACES Arc Melt/ Bell Jar Furnaces Arc melt furnaces provide a cost saving alternative to resistance or inductance heating furnaces for many applications. Rather than resistance heaters or induction coils, an electric arc is used to heat up and/or melt parts. Our Arc Melt Furnaces can instantly reach temperatures over 3500C, and will cool down to room temperature in minutes. Our systems are simple to operate, are extremely reliable and have a low acquisition and operation cost. There are a multitude of available options such as load locks, splat rod, rotating hearth,...

Single Arc Melt Model SA-200 The SA-200 is our smallest arc melt furnace and has a 2” copper hearth with crucible which holds customer material. All our systems come as a complete turn-key system and can reach temperatures above 3500C instantly. Custom hearth cavities to produce specific melt shapes are available at no extra cost when specified at time of order. • • • • • • • • • • • Operating temperature: over 3500°C. (6332F) Bottom loading configuration. 360o viewing through Pyrex glass between top and Bottom brass base. Vacuum chamber construction. Copper stinger with tungsten electrode....

Tri Arc Melt Model TA-200 The TA-200 arc melt furnace is identical to our Model SA-200, with the exception that it is equipped with three stingers instead of one. Three arcs allow for a larger and more homogeneous melt and makes it suitable for crystal growing (optional). Operating temperature over 3500 Deg. C. Bottom loading configuration. 360o viewing through Pyrex glass between top and bottom brass base. Vacuum chamber construction Three copper stingers with tungsten electrode.
