Protection of plasma cutting machine nozzle electrode

CNC plasma cutting machine is more and more in the carbon steel cutting, and its cutting efficiency and overall cost loss have more and more advantages. Relative to the same type of flame cutting, the efficiency is 5-8 times that of flame cutting, and the cost per day is only 1/6 of flame cutting. Because plasma cutting is mainly based on the ion arc formed by the current breakdown of air, the metal materials are segmented. Its cost loss is mainly electrical and plasma cutting machine nozzle electrodes, and nozzles and electrodes are many customers often headache, feeling loss is too fast.

Next, we mainly talk about how to protect the nozzle electrode of plasma cutting machine more effectively and prolong its service life.

1. For the numerical control plasma cutting, the automatic height of the arc pressure must be configured to ensure the effective distance between the nozzle and the steel plate, so as to improve the service life of the cutting nozzle and the cutting effect of the plate.

2. we need usually use cut the needle to clean the mouth of the nozzle to ensure that it will not be blocked by iron slag dust and burn the electrode.

3. When the plasma cutting machine nozzles are seriously damaged, they should be promptly broken down, not supported, and will affect the internal electrodes and other vulnerable parts.

4. When cutting different thickness plates, the corresponding current quantities should be selected. Damage will be caused to the nozzles and electrodes if they are too large or too small.

5. For a long time, the nozzle electrode can be unloaded, and then installed when needed, so that the long time device in the large factory of smoke and dust, the long time added a large humidity, will affect the performance of the nozzle electrode.
