The chamber is constructed of a water cooled brass top and bottom, and has a full 360° viewing area. During operation, three sided viewing through protective eye shields allows excellent visual exposure to the melt while blocking radiation from the welding arc.
The top of the chamber houses the stinger which allows the user to move the welding arc around in the chamber. The chamber base houses the copper crucible which holds the melt material. Clamps secure the crucible in place.
A vacuum pump, manual vacuum valve and mechanical vacuum/pressure gauge is supplied to easily evacuate the chamber below 0.1 Torr (mbar). The vacuum system allows the removal of air and oxygen from the chamber after the melting material has been loaded. Removal of oxygen prevents oxidation and/or combustion of the melting material.
Inert Gas System:
A manual gas valve is supplied to quickly back-fill the chamber to a slightly positive pressure after evacuation and to keep a blanket gas flowing while arc melting. A 2 PSI relief valve relieves excess gas while maintaining a positive pressure in the chamber. A flow indicator allows gas flow to be accurately modulated. Chamber pressure is displayed on an easy to read dial gauge.
A water manifold distributes water to the various water cooled components such as the power cable, stinger, chamber base and chamber top.
