Arc Melting System with 3 Cavity and Casting Function up to 200g - AM-800-3

Please email for lead time

Product Options

AM-800-3 is a larger and high vacuum arc melting system with three melting cavities ( crucibles) which have magnetic stirring ( around 80g),  vacuum casting ( round  150 g) and rectangular shape ( 200 g Max.).  The multi-function arc melting system can carry on various experiments to explore new generation alloy.


  • Water-cooled SS vacuum chamber which can reach vacuum up to 10-5 torr
  • Powerful arc melting power supply, which enables arc ignition without touching the sample
  • Water cold copper plate with three types of the crucible with a different function.
    • Round cavity: 80g max. with magnetic stirring function
    • Round cavity: 150g max. with vacuum casting function
    • Rectangular cavity:  200g max.  melting only
  • Arc electrode gun is driven by the electric motor for upward or downward for easy operation
  • A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum        
Power Supply
  • 15KW, 50/60Hz, three phases required
  • 208VAC  or 380VAC, 460VAC is available upon request
  • Arc melting current:  800A max.
Melting Chamber
  • Vacuum chamber with water cold wall jacket made of SS304
  • The chamber size: 400mm Dia x 350mm height with quart glass window hinged type door in the front
  • Vacuum level: 10 -6 torr via the included turbopump and baking heater.
  • High purity ( > 4N) Argon gas is required for arc melting
  • A tinted observation window on the front for monitoring the melting process
  • A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum
Water Cold Copper Hearth

( Choose one for your application in standard package)

  • Option 1: the water-cooled copper hearth has 3 cavities with the different function ( see pic 1 below)
    • Round cavity: 80g max. with magnetic stirring function built in the bottom to make alloy homogeneous.
    • Round cavity: 150g max. with vacuum casting function built in the bottom ( casting mold with diameter 8 or 10 mm  is included .  please decide mold ID before purchasing, the extra mold is available upon request )
    • Rectangular cavity:  200g max.  melting only
  • Optional 2: 4 cavities copper hearth is available for melting up to 600 g per charger ( see Pic 2 below),  Among them, one cavity has 1 mm hole to connect to water cold vacuum casting mold  ( mold diameter 5 -  8 mm is available upon request ( Pic. 3)

    ( Pic. 1)                   (Pic. 2)    ( Pic. 3)
  • Note:  The melting weigh is calculated based on SS304
  • Optional: customized crucible design is available upon request.  Please provide a sketch.
Tungsten Electrode
  • Water cold W electrode: 9.5 mm Dia
  • The electrode can swing at 150 mm radius to reach each cavity
  • The electrode can adjust height  0 - 50 mm from the bottom cavity
Vacuum Pump 
  • The vacuum level is dependent on the vacuum pump used:
  • The vacuum pump is not included.  Please choose a vacuum pump system based on your application.
  • Note: A high vacuum pump is not necessary for some alloys.  you may choose a mechanical pump and purge chamber by high purity Ar gas several times before melting if you have a limited budget.
Water Chiller & Gas (Optional)
  • CE certified
  • UL/CSA certification by NRTLs is available at an extra fee.
  • One-year limited warranty with lifetime support
