Arc Melt Furnace- Tri Arc 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. Triple arcs allow a larger and more homogeneous melt. This Arc Melt Furnace can instantly reach temperatures over 3000 deg. C, and will cool down to room temperature in minutes. It is simple to operate, extremely reliable and has a low acquisition and operation cost. The available options such as load locks, splat rod, rotating hearth, crystal growing kit, oxygen monitor and more, make this furnace versatile and adaptable. MRF Model TA-200 specifications:            Operating temperature: over 3000 Deg. C. Bottom loading configuration. 360o viewing through Pyrex glass between top and bottom brass base.
