What measures should welders take to prevent arc radiation?

In fact, prevention can't be prevented, and it can only reduce the harm of welding operation to people as much as possible. Masks are necessary, such as long clothes, trousers, labor protection shoes and ventilation, because heavy metal smoke will be produced when welding electrodes are operated, which has great influence on the body and needs regular rest. In fact, many units and welders have ignored this point, which is the most important and easy to ignore.
