![]() The method of testing the gas quality is to set the cutting torch in a test state, and put a mirror under it to consume the gas in the cutting torch. Dirty gas is usually a problem with gas compression systems, which can shorten the life of consumables and cause abnormal damage. ![]() Plasma cutting systems require dry and clean plasma gas to function properly. ![]() For example: the current intensity of a 100A nozzle should be set to 95A. The current intensity should be 95% of the working current of the nozzle. Overloading the nozzle (that is, exceeding the working current of the nozzle) will quickly damage the nozzle. Try to cut within the range of the normal cutting thickness rated by the plasma cutting machine, try not to cut on the limit cutting thickness, the normal cutting thickness of domestic cutting machine is generally 60% of the maximum cutting thickness marked by the manufacturer, try to cut within this thickness range, The best protection of the cutting mouth. The usual perforation thickness is 1/2 of the normal cutting thickness. Plasma cutting machine can't perforate on the steel plate which exceeds the working thickness. The Thickness of the Perforation and Cutting Should be Within the Allowable Range of the Plasma Cutting System. The service life of the nozzle will be doubled, and it will even be burned out when it is installed. The life is reduced if it is too close, it is simpler, and the nozzle is very expensive. This distance should be kept as constant as possible, usually about 3-8mm. The tangent distance is the distance between the cutting nozzle and the surface of the workpiece. Refer to the instruction manual of the plasma cutter when setting. 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. The correct pressure and flow of the plasma is important to the life of the consumable.
