How to use plasma cutting machine correctly? The correct air pressure and flow of plasma are very important for the service life of consumables.If the air pressure is too high,The life of the electrode will be greatly reduced;The air pressure is too low,The life of the nozzle will be affected.According to the requirements of the instruction manual,Using a reasonable cut distance,The cut distance is the distance between the cutting nozzle and the surface of the workpiece,When piercing,Try to use 2 times the normal cut distance or the maximum height that can be transmitted by plasma arc.The plasma cutting machine cannot be punched on steel plates that exceed the working thickness,Overload the nozzle (I .e. exceed the working current of the nozzle ),Will damage the nozzle quickly.The current intensity should be 95% of the working current of the nozzle.For example, the current intensity of the 100A nozzle should be set to 95A.The plasma system requires dry and clean plasma gas to work
