|
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 turbo pump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbo pump) 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. Please click pic 4 to watch the demo video.
