Recently, when a unit was conducting air welding operations, people suddenly heard a scream followed by a boring percussion. An electric welder was seen falling from a height of 3 meters and was immediately killed. After investigation, the welder in the welding of an electric hoist iron frame, the use of aluminum lift, the upper end of the ladder against the electric hoist rail. The worker’s arm rests against a metal ladder, holding a torch in one hand and holding a welding rod in the other hand, trying to replace it, but the hand touches the metal core of the welding rod that has been clamped on the welding torch. The current flows through the aluminum ladder and the second Second line, through the human body. The accident, the welder used for the BX1 type, no-load voltage
