In the actual production and its investigation, we found that in terms of the use of the cutting nozzle of the fine plasma cutting machine, for many enterprises, in fact, they do not pay much attention to it. However, when considering from the cost point of view, the loss of the electrode cutting nozzle constitutes a major cost source of the fine plasma cutting machine to a large extent. At this time, it is also important to use the cutting nozzle efficiently.

The automatic laser welding machine manufacturer first said that when using the fine plasma cutting machine, we should pay attention to the fact that we should cut as few holes as possible. In fact, the perforation, that is, the reverse splashing of molten steel, will damage the nozzle, which is actually the main reason for the damage of the cutting nozzle. When we must use the perforation for cutting, we should also In the place where the hole is drilled, the drill bit is used to drill the pre hole directly, and then the cutting is started from the place where the pre hole is drilled.

NC plasma cutting machine manufacturer's introduction follows. We should pay attention to cutting in the range of normal cutting thickness rated by fine plasma cutting machine as much as possible, not in the limit cutting thickness. In terms of its normal cutting thickness, generally speaking, it is 60% of the cutting thickness marked by the manufacturer.

In fact, the distance between the cutting nozzle and the steel plate should be kept at a constant distance as far as possible. In general, it will be about 3-8mm. When it is too far away, it will not only consume a lot of electricity, but also greatly reduce its cutting penetration.

Relatively speaking, when the fine plasma cutting machine is in this situation, it will actually consume more electrodes, making the service life of the electrode show a linear decline; in addition, when it is too close, the structure of the fine plasma cutting machine will be more simple, it will especially cost the nozzle, and the service life of the nozzle will also show up The characteristic of a multiple decline.
