Vacuum Arc Remelting Furnaces (VAR)

VAR Furnaces for melting material that have already been melted and cast into electrodes that are near their full packing density. Consarc utilises fully computerised controls to optimise reproducibility and ease of operation. Custom furnaces in laboratory scale or for the production of unusual geometric configurations are available upon request.
