  • Patent number: 9731375
    Abstract: A method for plasma cutting a workpiece comprises providing a plasma cutting system having a plasma current source and a plasma torch, the plasma torch having an electrode and nozzle where the nozzle is a small distance from the electrode at a lower end of the plasma torch, forming a plasma chamber between the nozzle and the electrode. A current is produced with a plasma current source and the current flows through the plasma torch during the plasma cutting process. The current is then brought to pulsation during at least a partial time period during the plasma cutting process, with the pulsation occurring in a targeted or controlled manner with a freely selectable frequency.
