What are the hazards of high frequency electromagnetic fields generated during plasma spraying

       The main harm to the human body of the high-frequency electromagnetic field during plasma spraying is magnetism. It can cause certain dysfunctions of the central nervous system. Under the action of high-frequency electromagnetic field for a long time (such as when the electromagnetic field strength exceeds 10V/m), the operator will feel general discomfort, fatigue, weakness, headache, dreaminess, memory loss, and some may cause symptoms such as hair loss and chest tightness.



     High-frequency electromagnetism mainly occurs during high-frequency arc ignition. Because the power of the high-frequency oscillator is small and the time is very short, the harm to the human body is also small. As long as the arc ignition performance of the equipment is improved during the arc ignition process, the weak high-frequency spark can be used to instantly start the arc, and the high-frequency circuit can be cut off immediately, so that the influence of the high-frequency electromagnetic on the operator can be minimized.
