How To Prolong The Service Life Of The Consumed Parts Of Plasma Cutting Machine

1. Ensure the correct pressure and flow of plasma;

The correct pressure and flow of plasma is very important for the service life of consumable parts. If the air pressure is too high, the life of the electrode will be greatly reduced; if the air pressure is too low, the life of the nozzle will be affected. Refer to the operation manual of plasma cutter when setting.

2. Adopt reasonable tangent distance & nbsp;

The cutting distance is the distance between the cutting nozzle and the workpiece surface, which should be kept constant as far as possible. Generally, it is about 3-8mm. It is too far away, not only the power consumption is too large, but also the cutting penetration ability will be reduced, and the electrode service life will be reduced relatively. Although it is too close, it is very simple, but it costs a lot of nozzle, and the service life of the nozzle will be doubled, even if it is installed, it will be burned When perforating, try to use 2 times of the normal cutting distance or the maximum height that can be transmitted by plasma arc.

3. The perforation thickness and cutting thickness should be within the allowable range of the machine system;

Plasma cutting machine can't pierce the steel plate which is more than the working thickness. The usual perforation thickness is 1 / 2 of the normal cutting thickness. Try to cut within the rated normal cutting thickness of the plasma cutting machine, and try not to cut on the limit cutting thickness. The normal cutting thickness of the domestic cutting machine is generally 60% of the maximum cutting thickness marked by the manufacturer, and try to cut within this thickness range, so as to best protect the cutting nozzle.

4. Keep the plasma gas dry and clean;

The plasma system needs dry and clean plasma gas to work normally. Dirty gas is usually a problem of gas compression system. It will shorten the service life of consumable parts and cause abnormal damage. The way to test the gas quality is to set the cutting torch in the test state, and put a mirror under it to consume the gas in the cutting torch. If there is moisture and mist on the mirror, it is necessary to find out the reason.
