In the process of using the CNC plasma cutting machine
, it is very important to adjust the current of the plasma power source for the machine to affect the cutting quality of the workpiece during the actual cutting process. Different thicknesses have corresponding current adjustments. Only by mastering the current adjustment operation, can the plasma cutting machine be used correctly to achieve the best cutting effect.
When the CNC plasma cutting machine cuts the workpiece, it is very important to adjust the cutting current of the machine plasma power supply. The most important cutting process parameters directly determine the cutting thickness and speed, that is, cutting capacity. The impact caused is directly expressed as the selection form of the cutting current of the plasma CNC cutting machine:
1. The cutting current of the plasma CNC cutting machine increases, the plasma arc energy increases, the cutting capacity increases, and the cutting speed increases accordingly;
2. The cutting current of the CNC plasma cutting machine
increases, the diameter of the plasma arc increases, and the arc becomes thicker to make the cut wider;
3. Excessive cutting current of CNC plasma cutting machine increases the thermal load of the nozzle, the nozzle is damaged prematurely, the cutting quality naturally declines, and even normal cutting cannot be performed. Therefore, the cutting current and the corresponding nozzle should be correctly selected according to the thickness of the material before cutting.
