The plasma power supply of the CNC plasma cutting machine can be selected according to customer requirements. The cutting quality required by the customer is relatively high. For the relatively small cutting port, we recommend its choice of imported plasma power sources such as Hypertherm and Pegasus. Some customers do not require high cutting orifices. We recommend that domestic power supply be selected, and domestic power supplies have good results in the middle, and the development of plasma power in the country has advanced by leaps and bounds in recent years, and the technology is maturing. In addition, domestic plasma power supply prices are relatively easy to accept and the price/performance ratio is very high.
Plasma cutting with plasma cutting machine is a disadvantage of plasma power. The domestic slope is about 8 degrees, and the import is about 4 degrees. At present, there is no good solution at home and abroad. We only try to think about how to properly operate the method so that the CNC plasma cutting machine can achieve the best effect of plasma cutting and the specific method is as follows:
1. The service life of consumables such as plasma torches is divided into domestic and imported. The normal service life is not the same. Some customers who want to save consumables beyond their useful life limit will have large cutting edges, and excessive use of cutting tips will also have a significant impact on the life of the torch itself. We recommend that customers must promptly replace plasma cutting. Consumables such as mouth, so as to ensure the quality of the product and the normal use of the cutting machine.
2. There is a relationship between mouthwash and elevation of arc pressure. If the steel plate fluctuates or deforms during the cutting process, the torch will automatically adjust its distance to the plate as the arc voltage changes, which also has a great influence on the cutting groove.
3, the distance between the cutting nozzle and the metal material also determines the size of the mouthwash (imports generally 2-5mm is better). The experience of the operator here is particularly important. A good operator will determine the optimum height of the cutting nozzle to the surface of the steel plate according to the thickness of the steel plate, which ensures the quality of the product without affecting the cutting efficiency.
