How can cutting torches be used with plasma cutting machines? I believe that this problem is a problem that many companies are quite concerned about. In the use of CNC plasma cutting machines, the use of cutting tips is an important factor directly related to the cutting cost. The following Dongguan Zhen Leili will provide you with a brief Analyze the key to long-life use of plasma cutting torch.

1, as little as possible perforation cutting, perforation is molten steel back splash will hurt the nozzle, which is one of the most important reasons for cutting nozzle damage, if you must perforation cutting, it is best to use holes in the perforation with a drill pre-drilled hole, from Pre-drilling starts cutting;

2, try to cut in the normal cutting thickness range of the cutting machine, try not to cut in the limit cutting thickness, the normal cutting thickness of domestic cutting machine is generally marked by the manufacturer's maximum cutting thickness of 60% (example domestic 100A plasma cutting machine Manufacturers marked the maximum cutting thickness is generally 32mm, but the normal normal cutting thickness is only 15-20mm), as far as possible in this thickness range of cutting, you can best protect the cutting nozzle;

3, cutting the distance from the nozzle to the steel plate as much as possible, usually about 3-8mm, too far not only the power consumption is too high, the cutting penetrating power will decrease, and the relative consumption of the electrode, so that the electrode life is reduced; too Closer to that, it's simpler, it's very costly, and the life of the nozzle will drop exponentially, even if it gets burned.

Of course, the service life of the plasma electrode nozzle is also related to other factors, such as: the level of the input voltage, the quality of the electrode itself, the quality of the plasma cutting machine, the degree of equipment integrity, the quality of the plasma torch, and the user The experience and so on, but the most important is the above 3 points. If the 3 points are taken care of, the service life of the electrode nozzle will be greatly improved.
