• The vacuum level is dependent on the vacuum pump used:
• 10^-3 torr via a mechanical/roughing pump. (Roughing Pumps) 
• 10^-5 torr via a turbopump. 
• Using a gas purification system ca keep oxygen < 1 ppm , which is equal to 10-6 torr vacuum
•           

• Water cooling is required (not included) for the chamber, copper mold, and electrode. Please consider our KJ-5000 recirculating water chiller.

• Layered amorphous silicon as negative electrodes in lithium-ion batteries, Journal of Power Source, 332(2016), Leyi Zhao, et. al

• 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.1)
• 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. 2)
• Must Wear Welder Glass or Auto Welding Shade while observing the Arc while welding. 
• 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 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 3 to watch the demo video.
