Causes and solutions of arc instability of plasma cutting machine:
1, the air pressure is too low or too high, adjust the air pressure;
2. Burn the electrode or nozzle in the torch, replace the electrode or nozzle;
3, input AC voltage is too low, adjust the input voltage
4, cutting ground and workpiece contact is not bad, re-clamping or replacement
5, cutting movement speed is too slow, adjust the cutting speed
6, spark discharge electrical appliances can not automatically break the arc, normal discharge 0.5s, maintenance
7, the host of the relevant components are not working properly and need to maintenance
