摘要：
The nozzle design has a considerable influence on the dimensions of the arc, its degree of constriction, and the coefficient of concentration along its length. The arc diameter increases with the increase of its length, the current, and the nozzle diameter, and it decreases when the consumption of plasma-forming gas is increased. The length of the nozzle channel has hardly any influence on arc dimensions, which depend on the type of shielding atmosphere.
