  • Method and device for plasma cutting of non-metallic materials
    Patent number: 4691090
    Abstract: An improved method and arrangement for cutting non-metallic materials by means of a plasma arc which is formed between a plasma torch and a confronting non-melting electrode-anode. The arrangement includes an arrangement for rotating the electrode-anode during and/or prior to cutting and an arrangement for forcibly elongating the plasma arc prior to cutting by increasing the distance between the plasma torch and electrode-anode prior to cutting. The arrangement includes a support for jointly supporting the plasma torch and electrode-anode. This support is adapted to be partly or completely moved relative to the non-metallic material to be cut. Conduits for a cooling medium are incorporated in the support and the non-melting electrode-anode.
