Abstract: An anti-dross-attachment agent application apparatus for plasma cutting, suitable for effecting a piercing start on a member to be cut, and designed to unman or automatize the plasma cutting operation. An anti-dross-attachment agent jetting nozzle (4) and a pump (7) capable of moving together with a plasma torch (1) of a plasma cutting machine are attached to a reciprocating base (2) on which the plasma torch is mounted. The apparatus has a piping (8) for supplying compressed air to the nozzle, an electromagnetic valve (9) for opening/closing the pipe passage thereof, and a controller (11) for controlling the operations of the pump and the electromagnetic valve. The arrangement may alternatively be such that an anti-dross-attachment agent spray can (34), an actuator (39) for depressing a valve of this spray can, and a nozzle tube (36) are attached to a reciprocating base on which said plasma torch is mounted, and that a controller (11) for controlling the operation of the actuator is provided.
