The problem of plasma cutting
 
1, spark generator can't be broken arc
 
Plasma cutting machine work, first of all to ignite the plasma arc, by the high frequency oscillator excited gas between the electrode and the inner wall of the nozzle, resulting in high-frequency discharge, the gas ionization and the formation of local small arc, the small arc by compressed air and ejected from the nozzle to ignite the plasma arc, which is main task spark generator. Under normal circumstances, the spark generator working time is only 0. 5 ~ 1s, the reason does not automatically break arc is generally offset control circuit board components, discharge electrode gap of the spark generator is not right. Should always check the spark generator discharge electrode, make the surface smooth, timely adjustment of the discharge electrode gap spark generator (0. From 8 to 1. 2mm), it is necessary to change control board.
 
2, poor contact with the ground
 
The ground is the essential preparation before cutting work a. Without the use of special grounding tool, workpiece surface insulation and long-term aging serious ground, will cause poor contact with the ground. Should use special grounding tool, and check whether the insulation effect of the ground contact with the workpiece surface, avoid the aging ground
