How to do plasma cutting machine maintenance work well

With the use of plasma cutting machine more and more frequently, it is more and more easy to cut steel. So CNC plasma cutting machine in the working process of cutting is not smooth, cutting surface quality is not good, what are the reasons? When the cutting surface is deformed and some parts are burned out, how to solve these problems? What problems should we pay attention to during the use process?

1. Cutting torch and wearing parts.

The function of the plasma system requires very high cleanliness, so any stolen goods from cutting torches and fragile parts will affect the performance of the machine. In the replacement of vulnerable parts, it is necessary to put them in a clean place, but also to check the connection thread of the torch, with hydrogen peroxide cleaning electrode contact surface and nozzle.

2. Protective cover

In the process of using plasma cutting machine, it is often found that there is slag on the protective cover of cutting torch. These slag should be cleaned up in time, otherwise it will cause destructive "heavy plasma arc". In addition, spraying anti-splash chemical coating on the protective cover can also help reduce slag accumulation, but it should be noted that the protective cover should be removed from the torch before applying anti-splash coating.

3. Nozzles

The nozzle of plasma cutting machine will deposit oxide, especially when air or oxygen is used as ionic gas, the oxide will affect the cutting gas flow and reduce the life of vulnerable parts. So cleaning the inner side of the nozzle with clean flannelette can eliminate oxides.
