Edmund Bühler AM 200 Arc Melter

Series: Arc Melting

Model: AM 200

An arc-melting system for metal samples up to approximately 200 g and 3500°C, with a water-cooled copper crucible plate, high-vacuum chamber and movable tungsten electrode.

Application / measured object:

Arc melting and materials preparation of metal and alloy samples up to approximately 200 g.

Application area:

Product overview

AM 200 provides arc melting of metal samples up to approximately 200 g at temperatures up to 3500 °C, using a water-cooled high-vacuum chamber, movable tungsten electrode and copper crucible plate.

Key features

  • Water-cooled copper crucible plate with multi-purpose moulds for button and rod samples; customised moulds are available on request.
  • Double-walled water-cooled high-vacuum chamber, with an electric chamber lift.
  • Motor-driven water-cooled tungsten electrode moves freely above the crucibles; viewing ports permit process observation, with major controls at the top of the electrode.
  • Contactless arc ignition; high-vacuum pumping and measuring systems are built into the rack, ready for operation.
  • Generator configurations are available with maximum currents of 400 A or 800 A.
  • Safety features include emergency stop, chamber-lift sensor, protection-glasses sensor and cooling-water flow control.
  • Sample manipulator, tilt casting, suction casting and recirculating chiller are optional, not universal basic equipment.
