The Model 5SA Single Arc Furnace is a compact, easy to operate, lightweight and inexpensive basic research tool used to produce high purity melts. The furnace system consists of the Single Arc Furnace, a D.C. power supply, and a set of water-cooled power cables to bring power and water to the furnace. Because of its simplicity, ease of access into the furnace, and small volume, the furnace is very easily purged. Work specimens are, therefore, very quickly prepared and a very high degree of purity is maintained from sample to sample.
Due to the extremely high temperatures available by the arc technique, temperature in excess of 3500°C can be attained. Material such as molybdenum and tungsten are readily melted and extremely high purity is attained. More difficult materials such as zirconium oxide, aluminum oxide, etc., are melted by surrounding the material by the arc plasma.
In the past, arc melting furnaces tended to be large, cumbersome and expensive; but, there is a unit that can be carried under your arm, set-up in minutes on any convenient table top, and is such a marvel of simplicity that anyone can operate it.
