Product Options

Vacuum pressure gauge:

EQ-SP-MSM207 is a compact vacuum arc melting furnace with a non-consumable tungsten electrode and water-cooled copper crucibles. A built-in mechanical manipulator is included for tilting and rotating metal ingots for the re-melting process. Vacuum casting faction fixture can be added as optional. It is an excellent tool for smelting metal alloys for phase diagram research.

Application & Warning Notes	5N purity Ar gas is required for arc melting. Gas purification module is recommended to ensure gas purity. (click Pic.1 to order) A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 psi for safe operation. Click here to learn the installation of a gas regulator (Pic.2) To avoid any damages to the mechanical pump or turbopump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbopump) on the pump inlet port (Pic. 3) Must Wear Welder Glass or Auto Welding Shade while observing the Arc while welding. An example of the system setup with the turbomolecular pump can be on the left The unit is designed for arc melting operation under tiny positive pressure or low vacuum (0.01 – 0.11 MPa pressure, or positive 0.01 MPa to negative 0.09 MPa pressure). Never operate the unit at high vacuum or high positive pressure! During the arc melting operation, never allow the electrode to touch the material or the copper crucible! Do not operate the mechanical manipulator during the melting process. Option: The user may use a quartz tube shielding to effectively reduce the splash and spilling while arc melting.
