Arc Melter

The arc melting process takes place in a cylindrical chamber that can be filled with argon gas after the air is evacuated by an integrated vacuum pump. An adjustable high voltage is applied on the sharp tip of the tungsten electrode to create a potential difference between the electrode and the sample. The current discharge will take place between the electrode and the specially-designed water cooled copper crucible where the sample is placed. The electrode can be easily moved inside the chamber to access different samples during the operation.  This equipment has many applications such as melt-mediated alloy fabrication, metal tube sealing, etc.
