Economic 16-Cavities Arc Melting System for Alloy Research - EQ-SP-MAM-16

Please email for lead time
Item Number: EQ-SP-MAM-16
EQ-SP-MAM-16  is a 16-cavities manually operated arc melting furnace in the glove-box without gas purification system.  .One16 cavities copper hearth with water cooling is installed in the glove box.  You can move arc torch gun to each cavity and melt metallic sample up to 2000°C.  It is an excellent tool for high-throughput MGI research such as alloy formation and phase diagram developments at an affordable cost.



  • The manually operated  arc melting system consists of:
    • Compact vacuum glove-box with air-lock chamber
    • One 16 cavities copper hearth with water cooling plate on bottom
    • 200A DC power supply with UL certification
    • Arc melting stinger/gun with KF40 feedthrough to connect into the glovebox
    • 16L/minute recirculating water chiller
    • The mobile cart is included for easy moving.
Arc Melting & Copper Hearth

  • Metals are melted with an electric arc in a water-cooled copper crucible which has 16 x 2 cavities (25mm Dia each). This allows the melting (up to 3000°C) of 32 specimens in a single batch without cross-contamination. (the numbers of the cavities are available upon customer request )
  • Copper Hearth is interchangeable and easy to take out or send in through airlock chamber on the glove box
  • The steel cover is included to protect the samples from cross-contamination.
  • Water cooled 4 mm diameter tungsten electrode /arc stinger is installed inside the glovebox via vacuum sealed feedthrough
  • Water cooled rectangular copper hearth is installed on bottom and of copper hearth 
  • Arc melting stinger/gun and water cooling plate can be installed inside or outside of the glovebox based on customer request
Vacuum Glove Box
  • Case Material: Made of 11 gauge (3mm thickness) 304 stainless steel sheet with support frame and plastic painting, which provide heavy duty structure for vacuum
  • Dimensions: 780mm(L) x 700mm(W) x 650mm(H)
  • Max. Positive Pressure: 810 Torr (1.1 atm)
  • Max. Vacuum Level: 0.5 Torr with mechanical pump
Gas Control
    Power supply  

    • Input Voltage: Single phase  AC 220V+/- 15% . 50/ 60Hz
    • (Three Phase  AC 380V 50Hz is available upon request)
    • Input Power:   6.3KW, 30A Max.
    • Output Power  DC, 56V (OVC), 10 - 190A max. adjustable
    • Optional: larger current up to 300A is available at additional cost.
    Water Chiller & Gas 

    • 16L/minute Recirculating water chiller is included for cooling copper mold. Please consider 5N high purity Argon gas is required for running arc melting
    • One vacuum pump is included for faster purge and loading or unloading sample via a clock chamber.
    • The pump and Water chiller are located inside a mobile cart  ( see pic below right )
    • This Unit has no gas purifying system.  You must use5N  high purity Ar gas for arc melting.  You may need purging gas 2-3 time to avoid sample oxidation.
