Arc Melt Furnace- Single Arc MODEL SA-200 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 smallest Arc Melt Furnace can instantly reach temperatures over 3000C, and will cool down to room temperature in minutes. The SA-200 Arc Melt Furnace is simple to operate, extremely reliable and has a low acquisition and operation cost. The available options such as load locks, rotating hearth, and more, make this furnace versatile and adaptable.

The hearth plate (anode) is copper and has an o-ring vacuum seal. Cavity dimensions: 2.0” (51mm) diameter Custom cavities in the bottom hearth plate are provided at no charge An optional rotating hearth is available (1- 60RPM) 4. Inert gas system:  This furnace system was designed to operate in argon.  A pump-out followed by a gas backfill provides a fast way to remove all oxygen from the chamber.  The standard positive pressure for operation is .14 kg/cm sq (2PSIG).  A relief valve and a 30/30 compound gauge (30 PSIG x 30 in. Hg) are located on the chamber. 5. Vacuum System:  A 4CFM...
