Is the mechanical welder tired in Dai Sheng?

Dai Sheng mechanical welder is very tired, although it is not heavy physical labor, the electrode holder is not heavy, and the labor intensity is not great. However, the surrounding environment is very difficult. If outdoor equipment is welded, the temperature is high in summer, and you can bake steel plates to boil eggs. The sultry and barbecue situation of welders can be imagined. It's very cold in winter, so it's hard to freeze your hands and feet.
