Factors of air plasma cutting machine

Jinan Xiaojia CNC Machinery Equipment Co.,Ltd

1, plasma cutting machine power, there must be a high enough load voltage to random arc and plasma arc is not extinguished. 
2, no-load voltage and arc column voltage 
Increase the gas flow can raise the arc column voltage can strengthen the tightening effect of leaving the arc column plasma arc energy is more concentrated, stronger radiation, thereby increasing the rate of cutting speed and quality. 
3, the cutting speed 
Optimum cutting speed range is selected or according to instructions with the test device to determine, since the thickness of the material, different materials, low melting point, thermal conductivity, and the size of the melted surface tension and other factors, the cutting speed corresponding change 
4, the gas flow 
Excessive gas flows are too small to affect the cutting quality and cutting consumables life. Excessive gas flow, but is shorter arc column, excessive heat loss, is cutting capacity to weaken until the cutting can not be normal; gas flow is too small, lack of energy arc column, cutting capacity decreased, steel hanging bar will increase, and will clogging supplies, affecting the quality of supplies. 
5, cutting current 
Cutting current to be adjusted according to the actual situation. Cutting current increases, the arc energy is increased to improve the cutting ability, the cutting speed is subsequently increased; cutting current increases, increasing the diameter of the arc, the arc slit is widened so that thicker; excessive cutting current heat load increases so that the nozzle, the nozzle prematurely damage, cutting quality naturally decline, or even can not be properly cut. 
6, torch height controller accuracy and stability 
Torch height controller high precision and stability of the plasma cutting has a relatively large impact on quality.
