In modern industrial production, CNC plasma cutting machine is widely used in the processing of various metal materials due to their efficient and precise cutting performance. However, like all mechanical equipment, plasma cutters may encounter some common problems during use. , let’s discuss these problems and their solutions to help factory maintenance personnel better ensure production efficiency.

First of all, a common problem is that after turning on the "power switch" of the CNC plasma cutting machine host, the power indicator light does not light up. This condition can occur for a variety of reasons. The most common thing is that the 15A fuse core is broken. At this time, you only need to replace the fuse. In addition, if the air pressure on the pressure reducing valve is too high, it may also cause the power indicator light to not light up. In this case, the pressure needs to be adjusted to an appropriate range. At the same time, check whether any parts of the cutting torch are damaged or damp. If so, they need to be replaced or dried in time. If the pilot arc wire is broken or the cutting torch is damaged, the corresponding parts also need to be replaced.

Another common problem is that after pressing the plasma cutting torch switch, there is air flow in the nozzle, but neither "" nor "low" can cut. This may be due to improper distance between the electrode and nozzle, or damaged parts inside the torch. At this time, it is necessary to check and adjust the distance between the electrode and the nozzle, and replace the corresponding parts if there is any problem.

In addition to the above two problems, CNC plasma cutting machines may also encounter other problems during use, such as too slow cutting speed and uneven cutting surface. These problems are usually related to factors such as cutting parameter settings, cutting gas selection, and wear levels of electrodes and nozzles. Solving these problems requires adjusting cutting parameters, replacing cutting gas or worn parts according to actual conditions.

In order to avoid these problems, factory maintenance personnel need to perform regular maintenance and upkeep on the CNC plasma cutting machine. This includes cleaning the machine, checking that electrical wiring and air pipes are intact, inspecting and replacing worn parts, etc. At the same time, operators also need to strictly abide by operating procedures when using CNC plasma cutting machines to avoid malfunctions caused by improper operation.

In short, although the CNC plasma cutting machine may encounter some problems during use, as long as you master the correct solutions and maintenance knowledge, you can effectively ensure its normal operation and improve industrial production efficiency. I hope this article can be helpful to the majority of factory maintenance personnel and users.
