The overload reasons of CNC plasma cutting machine

What is the reason for overload of CNC plasma cutting machine?

1. Cutting thickness is too big.

The thickness of the steel is more than the power supply and the maximum cutting ability of the mouth. When we choose the numerical control plasma cutting machine, the manufacturer of the CNC plasma cutting machine will choose the suitable plasma power supply and the cut nozzle model according to the processing conditions of the enterprise. This can reduce the purchasing cost for the enterprise, and also make the cutting effect reach. Requirements, or the best cutting effect.

However, many enterprises fail to operate correctly when using plasma cutting machine. The thickness of material will exceed the cutting range, resulting in damage of electrode cutting nozzle and plasma power supply. Generally speaking, the average perforation thickness is half of the normal cutting thickness.

2. Nozzles are not used correctly.

Many people use the CNC plasma cutting machine to maximize the current intensity of the power supply to improve the cutting speed and efficiency, which will allow the electrode nozzle to be overloaded and damage the nozzle. Generally speaking, the current intensity should be about 90% of the working current of the nozzles.
