Inhaling this smoke can cause dizziness, headache, cough, chest tightness and shortness of breath. Long-term inhalation will cause pulmonary fibrosis, that is, welder's pneumoconiosis, which is often accompanied by complications such as manganese poisoning, fluorosis and metal smoke fever. The incidence of welder's pneumoconiosis develops slowly, with a long course of disease, and the general length of service is 15-25 years.
