摘要： A main arc ignition method capable of extending lives of a plasma electrode and a nozzle. For this purpose, before or immediately after starting arc, a plasma torch is supplied with a plasma gas at least either at a lower flow rate or at lower gas pressure; the plasma gas is switched to a gas flow rate and gas pressure of a time of cutting a work, after pilot arc is ignited between an electrode and a nozzle, or after main arc is ignited between the electrode and the work; and when generation of the main arc between the electrode and the work is detected, a pilot current is interrupted promptly by a semiconductor switch which is interposed in series with a resistance, in a pilot current circuit that is connected to the nozzle and supplies the pilot current to the pilot arc.

摘要： Not only damage to a nozzle caused by spatter generated during piercing is prevented but also the deterioration of the nozzle owing to a pilot arc is restrained, whereby the service life of the nozzle is significantly increased. To this end, the plasma torch is positioned at an initial level which is the distance between the plasma torch and a steel plate when generating a plasma arc to start piercing operation and which has been set equal to a cutting level which is the distance between the plasma torch and the steel plate when carrying out cutting operation. After generation of the plasma arc, the plasma torch is immediately raised to a piercing level which is more distant from the steel plate W than the initial level and piercing operation is performed at the piercing level. After completion of the piercing operation, the plasma torch is lowered to the cutting level to start cutting operation. Just after transfer from a pilot arc into a main arc, a pilot current is cut off by turning a transistor off.
