<p>A device for applying a dross adhesion preventive for plasma cutting, which is suitable for executing piercing start on a workpiece and is adapted to realize unmanned and automated plasma cutting operation. A nozzle (4) for injecting the adhesion preventive and a pump (7), both movable along with a plasma torch (1) of the plasma cutting apparatus, are fixed to a reciprocating table (2) having the plasma torch (1) mounted thereon, and the apparatus is provided with piping (8) for supplying compressed air to the nozzle, a solenoid valve (9) for opening or closing the piping, and acontrol unit (11) for controlling the operation of said pump and solenoid valve. Alternatively the device may be provided with a spray can (34) for the adhesion preventive, an actuator (39) for depressing the valve of this can, a nozzle tube (36), and further a control unit (11) for controlling the operation of the actuator (39).</p> |
