AM-400 is a high vacuum arc melting system that has four arc melting heads with independent digital DC power generators. The water cold cupper hearth in the vacuum chamber is rotatable so that the system can melt the alloys sample uniformly without manual swing up to 70 g ( Fe based)

SPECIFICATIONS:

Power Source for Arcing
  • 4 NRTL certified digitally controlled power sources are included and stacked on a mobile cart.
  • Each power source is output DC pulsing AC selectable
    • Input voltage: 208 - 240 VAC selectable, single phase, 50/60Hz
    • Output: 18 V / 250 A at 60% duty cycle - 240 V input
    • Minimum DC current output: 5 A
  • Total power requirement for 4 power sources
  • 15KW in total
  • 4 output plugs are required and each one with a 40A breaker
Arc melting Heads
  • 4 arc melting heads are fed through into the vacuum chamber.
  • Each head consists of a 4 mm diameter tungsten rod with a water-cooling sleeve
  • The position of each arc melting head is adjustable in length and angle
  • Capable melt 100 g alloy ( Fe based ) or 30g ( W based )
Copper Hearth
  • Rotatable copper hearth with water cooling jacket is built inside a vacuum chamber
  • The cavity dimension of the copper hearth: 100 mm Dia x 15 mm depth
  • Rotating speed: 1 - 20 rpm adjustable with digital display
  • > 58L/min recirculating water chiller is required, but not included , please click the picture below to order

                     
Vacuum Chamber
  • Water-cooled SS304 vacuum chamber with dimensions of Φ 300 mm × 320 mm H
  • Φ150mm front door for easy sample loading and retrieving
  • One tinted observation windows with 100 mm Dia for monitoring the melting process
  • KF 40 port is built in to connect a mechanical vacuum pump
  • ISO63 port with blind flange is built in to connect to a turbopump
  • two 1/4 fittings with needle valves are built-in for inert gas inlet and outlet
  • Pressure range: 10 -6 torr to 900 tor 
  • Leaking rate: < 5.0E10-7 Pa.l/S
Vacuum Pump (Optional)
  • The vacuum level is dependent on the vacuum pump used:
    • 10^-3 torr via a mechanical/roughing pump. (Roughing Pumps) 
    • 10^-6 torr via a turbopump. ( Turbopump must direct connects to chamber )

                   
Compliance
  • CE certified
  • UL/CSA certification by NRTLs is available at an extra fee.
Application & Warning Notes

1

  • 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)
  • 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.
