2 Safety protection articles such as welding overalls, insulating shoes, welding gloves and protective masks should be worn during operation, and safety belts should be worn when working at heights.
3 inflammable and explosive articles shall not be piled up around the welding operation site 10m.
4, rain and snow and windy weather above level 6 are not allowed to work in the open air. After rain and snow, water and snow should be removed before operation.
Before operation, check the welding machine and tools, such as the insulation of welding tongs and welding cables, the protective grounding of welding machine shell and the connection points of welding machine, etc. Before operation.
6 It is strictly prohibited to weld and cut the stress components in the diffusion area of flammable and explosive gas or liquid, in the running pressure pipeline and in the container containing flammable and explosive materials.
7 When welding the container for storing inflammable and explosive articles, it should be replaced and cleaned for many times according to the medium, and all the orifices should be opened. Only after testing and confirming safety can welding be carried out.
When welding in a sealed container, ventilation measures should be taken. During intermittent operation, welders should rest outdoors. The lighting voltage in the container shall not exceed 12V. The welder's body should be isolated from the weldment by insulating materials. There must be a special person to supervise welding, and the guardian should be familiar with welding operation procedures and rescue methods.
9 When welding copper, aluminum, lead and zinc alloy, you must wear protective equipment and work in a well-ventilated place. When welding in places with harmful media, anti-virus measures should be taken and forced ventilation should be carried out when necessary.
10 when the welding site is wet or the clothes of the welder are wet after sweating, it is forbidden to lean against the charged steel plate or workpiece. Welders should work on dry insulating plates or rubber mats, and cooperating personnel should wear insulating shoes or stand on insulating plates.
When welding 1 1, it is forbidden to float the temporary grounding wire, and it must be fixed, compacted and wrapped with tape.
12 operation, the power supply must be cut off under the following circumstances:
1. When replacing the welding machine connector.
2. When it is necessary to connect the secondary circuit to replace the weldment.
3. When the welding machine moves from one working position to another.
4. When the welder fails and needs maintenance.
5. When replacing the safety device.
6. When the work is finished or you leave the job site temporarily.
13 aerial work must comply with the following provisions:
1. Standard fire safety belts must be used and tied to a reliable frame.
2. A guardrail must be set up at 5m directly below the operating point, and there will be a special person to supervise it. Flammable and explosive articles must be removed from the area below the operating point.
3. You must wear a helmet and mask. Welding cable should be tied tightly at a fixed place, and it is forbidden to wrap it around or carry it on your back.
4. The welding machine must work on a stable operating platform, and the welding machine must be placed stably and firmly, with a good grounding protection device.
14 During operation, it is forbidden to clamp the electrode holder under your arm to move the workpiece to be welded or hang the welding cable around your neck.
15 welding, the secondary line must be in place. It is forbidden to use metal pipes, metal scaffolding, tracks and structural steel bars as loop ground wires. Handle wire is undamaged and has good insulation. Electric shock protector of electric welding machine must be installed on the welding handle line.
16 when welding cables pass through roads, they must be erected or other protective measures must be taken.
17 electrode holder welding wire shall not be placed near the arc or beside the hot weld. Don't roll the handle line. Measures should be taken to prevent the handle wire from being damaged by sharp objects.
18 Wear protective glasses or a mask when removing welding slag. Covered electrode tips should be stacked together.
19 the switch must be turned off after work, and the ground wire must be separated from the wire. And make sure that the fire has been put out before leaving the scene.
