The general principle of anti-shock measures for automatic welding production lines is to take safety measures such as insulation, shielding, isolation, leakage protection and personal protection to avoid humans from touching live objects.

 The specific methods are:

1. Improve the insulation performance of welding equipment and lines. The welding equipment and power cables used must be qualified products, and their electrical insulation performance must be compatible with the used voltage level, surrounding environment and operating conditions; the welding machine should be arranged for a special person to perform routine tasks. Maintenance and maintenance to prevent sun and rain, so as not to reduce the electrical insulation performance of the welding machine.

2.When the welder fails to repair, move the work place, change the joints or replace the safety device, the power must be cut off before operation.

3.When installing power to the welding machine, don't forget to install a leakage protector at the same time to ensure that people will automatically cut off power when they get an electric shock. When welding on wet or metal containers, equipment, components, the rated operating current must be less than 15mA, rated Leakage protector with operating time less than 0.1 second.

4. The ends of the welding machine casing and the secondary winding lead wire should be taken with good protective grounding or zero connection measures. When the power supply is a three-phase three-wire system or a single-phase system, a protective ground wire should be installed, and its resistance value is not More than 4Ω; when the power supply is a three-phase four-wire neutral point grounding system, a protective neutral wire should be installed.

5. Strengthen the education of workers' knowledge of electrical safety and self-protection awareness. It is required to wear insulating shoes and special insulating gloves when welding. Welding in the open on rainy days is prohibited. When welding in particularly humid places, people must stand on dry wooden boards or Rubber insulation sheet.

6. It is forbidden to use metal structures, pipes, rails and other metal connections for wires. Welding in metal containers or particularly humid places, the power supply of the running lights must use a safety voltage below 12V.
