• 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. 
• 

• Water cooling is required (not included) for the copper hearth and electrodes.
  Please consider our KJ-5000 recirculating water chiller.

• 50 kg

• 405 lbs
• 48"x40"x52"

• CE certified
• UL/CSA certification by NRTLs is available at an extra fee.

• One-year limited warranty with lifetime support

• 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 about the installation of a gas regulator (Pic.1)
• To avoid any damage 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 quartz tube shielding to effectively reduce the splash and spilling while arc melting. Please click pic 3 to watch the demo video.
