Abstract

The present work offers a new approach to a problem of electrode wear in DC arc plasma torches with gas stabilization. A new torch with a moveable nozzle equipped with both normal and worn cathodes has been tested. The results have shown that change of the nozzle-cathode tip distance lead to change of the arc voltage and the generated plasma so it can help to counteract the cathode wear and prolong the lifetime of the electrode.
