Compact Vacuum Arc Melting System with Large Cavity up to 200 g (Fe) - EQ-SP-MSM200

0.0/5 rating (0 votes)


EQ-SP-MSM200 is a compact arc melting furnace with a water-cooled copper hearth to melt metallic samples up to 200g (Fe as ref.). A built-in mechanical manipulator is included for tilting and rotating metal ingots for the re-melting process.  SPECIFICATIONS:

  • Designed for melting single samples of 200g  (Fe alloy) up to 3500 °C under Ar gas.
  • Water-cooled vacuum chamber, electrode, and copper hearth with one larger cavity  ( round or rectangular ) and several small cavities.
  • Powerful arc melting power supply (25KW)  enables reliable, stable arc ignition
  • Easy electrode tilting and height adjustment via a handwheel
  • A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum
  • A tinted observation window on the front for monitoring the melting process

Power Supply  
  • 208 - 240 VAC, single phase, 50/60Hz,  7kW
  • Output DC output:  350A/24V    @  35% duty cycle (max. 3.5 min continuous operation every 10 min)
    208A/21.2V @  60% duty cycle (max.6.0 min continuous operation every 10 min)
    210A/18.4V @100% duty cycle (continuous operation)
  • The HF function is included for easy arcing without contact with samples. 
Tungsten Electrode
  • 6 mm Dia. tungsten electrode with water cooling
  • Easy electrode tilting and height adjustment (30 mm max) for multiple-cavity melting
  • Capable of melting samples < 200 g iron-based alloy in each cavity up to 3500 °C.
Copper Crucible
  • Water-cooled copper crucible plate with one large capacity with several small cavities (Pic. 1). Please select cavity shape before ordering as follows:
    • Round cavity: 70 mm diameter x 15 mm Depth
    • Rectangular cavity: 200 mm L x 40mm W x 15 mm Depth
  • Three 25mm dia. × 12.5 mm Deep small cavities are used for Ti melting to reduce the trace oxygen inside the chamber before processing, or small samples for < 20 g
  • In order to melt the alloy uniformly, double side melting is required
Vacuum Chamber
  • Water-cooled vacuum chamber with dimensions of Φ 182 mm × 225 mm H
  • A Φ120mm front door for easy sample loading and retrieving
  • 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
Vacuum & Gas purification (Optional)
  • The vacuum level is dependent on the vacuum pump (not included, please order separately)
    • 10^-3 torr via a mechanical/roughing pump. (Roughing Pumps)  (Pic. 1)
    • 10^-5 torr via a turbopump. (Pic. 2)
  •  You may use a recirculating gas purification system to keep gas purity inside the chamber < 1 ppm O2 and H2O without turbopump. ( Pic. 3)

Water Chiller & Gas (Optional)
  • Water cooling is required (not included) for the chamber, copper mold, and electrode. Please consider our KJ-6200 recirculating water chiller
  • Water-tube for MTI Water Chiller is Size: 12mm O.D x 8mm I.D
  • High purity inert gas with at least 5N purity (>99.999%) is required (not included)
  • 5% Hydrogen + 95% Argon gas may be used to prevent oxidation during the melting process
Furnace Dimensions 
  • 540 mm W × 540 mm D × 920 mm H (exclude the power supply) 
  • Power supply dimension: 320 mm L x 185 mm W x 485 mm H
Net Weight
  • 50 kg
  • CE certified
  • UL/CSA certification by NRTLs is available at an extra cost
  • One-year limited warranty with lifetime support
Operation Manual & Video      200g sample video      small cavity melting video
Application & Warning Notes
  • 5N purity Ar gas is required for arc melting. A 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 turbopump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbopump) on the pump inlet port (Pic. 3)
  • 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.
