| 摘要 |
The apparatus for plasma arc cutting, in particular for the air plasma arc cutting of plate-shaped metal workpieces (11), comprises a work table (1), the top of which defines a work plane (2), and a plasma head (4) which has a nozzle (5), with a nozzle passage (5a), directed towards the work plane (2), for the discharge of a plasma arc cutting jet (10), as well as an electrode (7) behind the nozzle (5) for forming the plasma, and means (25) for feeding a cutting gas from which the plasma is formed, the plasma head (4) and the work table (1) being movable relative to one another parallel to the work plane (2), and the nozzle passage (5a) being directed towards the work plane (2) at an angle ( alpha ) different from 90 DEG . <IMAGE>
