Edmund Bühler Arc Melter AM 500
Original manufacturer document covering the corresponding product specifications, configuration or applicable loading conditions.
View resource →Product overview
AM 500 provides arc melting of metal samples up to approximately 500 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 and water-cooled flanges, 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.
- The manufacturer lists a maximum generator current of 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.
