Cutter for plasma burner

摘要

The cutter has a nozzle (3) and a nozzle holder (2) for mounting the nozzle on an operating end piece. The electrical contact which is required for the burner to work is made with a connecting part of the burner. The nozzle holder has a protector (1) for the nozzle on its free or lower end (21), consisting of a tubular element removably attached to the nozzle holder. The protector protrudes so far from the free end that lateral interactions with the nozzle walls are prevented.
