Fine plasma cutting machine is a new cutting technology between laser cutting and air plasma cutting. It has good performance in cutting material verticality and cutting thickness. At present, it is not fully equipped with fine plasma cutting in China. Electromechanical "target=_blank> machine power research and development capabilities, related products rely entirely on imported technical support, which also caused the relatively high cost of fine plasma cutting machine, making many end-user companies discouraged. Wuhan Jiabei Technology to 20011 The company has developed related supporting machine tools and equipments. At present, it has served more than 40 end-user enterprises in the domestic fine plasma cutting market. Through comprehensive understanding and data collection with customers and equipment, the consumables for fine plasma cutting machines are also used. A certain understanding and mastery, in order to facilitate the user unit to more fully understand the characteristics of this type of cutting method to reduce processing costs, the following we use fine plasma cutting machine consumables consumables use finishing 15 points of use rules, I hope to give you some Help and reference.
1. Keeping the torch and consumables as clean as possible on the plasma cutter torch and consumables can greatly affect the function of the plasma system. When replacing the consumables, place them on a clean flannel. Always check the connection threads of the torch and clean the electrode contact surfaces and nozzles with a hydrogen peroxide cleaner.
2. Removal of oxides from air or oxygen nozzles When air or oxygen plasma is used, oxides are deposited in the nozzles that affect the airflow and reduce the life of the consumables. Wipe the inside of the nozzle with a clean flannel to remove oxides.
3. Injecting hard water into the torch with demineralized water can cause metal impurities to deposit on the nozzle ring, which will affect airflow, reduce torch quality and shorten consumable life.
4. Daily inspection of airflow and cooling flow One of the most common causes of torch damage is the lack of cooling flow, which requires frequent inspection of the torch airflow and air pressure (if air cooled) or coolant (if water cooled), if airflow is found to be insufficient Or when it leaks, stop it immediately and troubleshoot it.
5. Ensure that the plasma is at the correct pressure and flow. The correct pressure and flow of the plasma is important to the life of the consumable. 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.
6. Use reasonable cutting distance According to the requirements of the instruction manual, use reasonable cutting distance, the cutting distance is the distance between the cutting nozzle and the surface of the workpiece. When piercing, try to use the distance of 2 times of the normal cutting distance or pass the plasma arc. The maximum height.
7. The thickness of the perforations shall be within the allowable range of the machine system. The cutter shall not be perforated on steel plates exceeding the working thickness. The usual perforation thickness is 1/2 of the normal cutting thickness.
8. Do not overload the nozzle. Using the plasma cutter nozzle overload (ie, exceeding the operating current of the nozzle) will cause the nozzle to be damaged quickly. The current intensity should be 95% of the operating current of the nozzle. For example, the current intensity of a 100A nozzle should be set to 95A.
9. Keeping the plasma gas dry and clean The plasma system requires a dry and clean plasma gas to function properly. Dirty gases are often a problem with gas compression systems, which can shorten the life of consumables and cause abnormal damage. The method of testing the quality of the gas is to set the torch in the test state, and place a mirror underneath it, consuming the gas in the torch. If moisture and fog appear on the mirror, you need to find out the cause and correct it.
10. Cutting should start from the edge as much as possible from the edge, rather than perforation cutting. Using the edge as a starting point will extend the life of the consumable. The correct way is to align the nozzle directly to the edge of the workpiece before starting the plasma arc.
11. Avoid extension of the plasma arc. If the plasma arc is only extended to reach the surface of the workpiece, the plasma arc will produce this stretching and expansion at the beginning and end of the cutting, which will cause abnormal nozzle damage. This problem can be avoided by using the correct edge starting technique and choosing the appropriate "broken arc" signal time.
12. Reduce unnecessary “arcing (or arcing)†time The nozzle and electrode are consumed very quickly when starting the arc. Before starting, the torch should be placed within the cutting metal walking distance.
13. Apply a splash-proof chemical coating to the protective casing. The splash-off chemical coating helps to reduce the accumulation of slag on the protective casing. However, it is necessary to remove the protective cover from the torch before applying the splash-proof paint.
14. Remove the slag from the protective casing and always remove the slag from the torch protective casing, otherwise the slag will cause a destructive heavy plasma arc.
15. Remove gas after replacing consumables. After replacing the plasma cutter consumables or for a long period of time, the gas should be purged (2-3 minutes) to ensure that water and mist are drained from the torch.

Downlights do not occupy space, which can increase the soft atmosphere of the space. If you want to create a warm feeling, you can try to install multiple downlights to reduce the pressure of the space. It is generally used in hotels, families and coffee shops.
