Plasma cutting machine maintenance and use
R&D of science and technology is the driving force for the continuous progress of society. The use of large-scale machinery has led to the continuous advancement of industrial civilization. As a part of the cutting machine industry, we always aim at innovation and serve our customers. Welcome everyone to discuss cooperation. Details:/
1. Proper assembly of the torch The correct and careful installation of the torch ensures that all parts fit well and that gas and cooling air flows. Installation Place all parts on a clean flannel to prevent dirt from sticking to the parts. Add appropriate lubricant to the O-ring, which is based on O-ring lightening.
2. Consumables should be replaced in time before they are completely damaged. Consumables should not be replaced after they have been completely damaged, because severely worn electrodes, nozzles, and swirl rings will generate uncontrolled plasma arcs, which can easily cause serious damage to the torch. Therefore, when the cutting quality is found to be deteriorating for the first time, the consumables should be checked in time.
3. Cleaning the connecting thread of the torch When replacing consumables or daily maintenance inspections, make sure that the internal and external threads of the cutting machine are clean. If necessary, clean or repair the connection threads.
4. Cleaning the contact surface between the electrode and the nozzle In many torches, the contact surface between the nozzle and the electrode is a charged contact surface. If these contact surfaces have dirt, the torch will not work properly. Hydrogen peroxide should be used. Cleaning agent cleaning.
5. Check the gas and cooling gas daily. Check the flow and pressure of the gas and cooling air flow every day. If you find that the flow is not sufficient or there is leakage, you should stop the line immediately.
6. Avoid cutting torch collision damage In order to avoid damage to the torch collision, it should be programmed correctly to avoid system overrun. Installation of anti-collision device can effectively avoid damage to the torch during collision.
7. The most common cause of torch damage (1) torch collision. (2) Destructive plasma arcs due to damage to consumables. (3) Destructive plasma arc caused by dirt. (4) Destructive plasma arc caused by loose parts.
8. Precautions (1) Do not apply grease to the torch. (2) Do not overuse the O-ring lubricant. (3) Do not spray splash chemicals while the protective sleeve is still on the torch. (4) Do not use a manual torch as a steamer.
