Precautions for preventing electric shock in welding

I. use qualified welding tools

carefully check the welding tools before operation, and the inspection items are as follows:

1 Whether the insulation performance of the welding machine is good

2. Whether the insulation layer of the power line and the outgoing line of the electric welding machine is damaged and aged, and whether the wire is exposed

3. Check whether the primary and secondary terminals of the electric welding machine are loose or severely burned

4. Check whether the electric welding tongs and special gloves for electric welding have the possibility of damage and leakage, and the unqualified ones are forbidden to use

II. Wiring shall be carried out in strict accordance with the wiring procedure

III. When entering metal containers, underground, trenches and other places for operation, it is strictly prohibited to bring in electric welding machines and portable lamp transformers for lighting, so as to prevent electric shock accidents caused by primary voltage

IV. during operation, especially when changing welding rods, you must wear welding insulating gloves as required

v. wear insulated shoes or stand on dry wood when working in wet environment. Work clothes, shoes and gloves with working viscosity characteristics should be kept dry to ensure that the insulation performance will not be reduced

VI. remove the power line and eliminate (1) the fixture equipped with the machine should be coated with anti rust oil for storage; Electric welding machine failure, mobile electricity from the existing project, remember to disconnect the power switch when the welding machine and the welder leave the site

VII. When the lighting on the welding site is insufficient, portable lamps should be used, 220V lamps are prohibited, and the voltage of portable lamps used in humid environment or metal containers should not exceed 12V

VIII. When electric welding must be carried out outdoors in rainy and snowy days, rain and snow proof measures must be taken (such as rainproof shed - "obvious trend of decentralization", etc.) to prevent rain from wetting the welding machine, wire and welding handle, causing electric leakage and personal injury accidents
