1. The plate does not penetrate the Mars
During the cutting process of the plasma cutting machine, the sheet may not penetrate, but there are a lot of spark residues on the surface. When such a failure occurs, three reasons can be investigated by checking the current setting, the cutting speed setting, and the wear of the torch parts. But it may also be caused by the sheet being too thick. At this time, it is necessary to adjust the increased current and adjust the cutting speed to improve.
2. Cut the bottom to produce slag
Slag from the bottom of the cut is also a typical cause of failure. At this point, the possibility of dross can be confirmed by checking that the cutting speed is correct. Bottom dross can also occur if the torch parts are worn too much. At this time, the cause of the failure can be confirmed by replacing the torch parts with new ones.
3. The cutting angle is not a right angle
When the plasma cutting machine encounters a fault such as a cutting angle that is not a right angle, it is necessary to check whether there is any deviation between the moving direction of the machine and the moving direction of the cutting torch components. At the same time, it is also necessary to check whether the size of the current and the setting of the cutting speed cannot meet the cutting requirements of the current workpiece. The reasons for these failures may result in that the cutting angle is not a right angle, which needs to be repeatedly confirmed through various inspection methods.
