  • Plasma forming gas ............................................. Ar, He, N, air or mixtures thereof
  • Plasma forming gas consumption (l/min) ............... 3-20
  • Types of melting crucibles .....................................scull-type (metal based), graphite, ceramic
  • Methods of pouring .................................... In vacuum, controlled atmosphere, under controlled pressure, free pouring in the open air
  • Types of re-melting metals .................................... ferrous, non-ferrous, refractory
  • Methods of melting ............................................... By direct or indirect plasma arc
  • Methods of metal agitation in the melting crucible ... Convection, electro-magnetic, mechanical, and combinations thereof
