Introducing The Safety Of Spot Welding Machines

1. On-site use shall be provided with a rain-proof, moisture-proof and sun-proof shed, and corresponding fire-fighting equipment shall be installed.

2. Within 10m of the welding site, no flammable or explosive materials such as oil, wood, oxygen cylinders, and acetylene generators shall be stacked. Spot welding

3. Welding operations and cooperating personnel must wear labor protection articles in accordance with regulations. And must take safety measures to prevent accidents such as electric shock, high-altitude fall, gas poisoning and fire.

4. The copper plate connecting the secondary tap should be pressed tightly, and the terminal post should have a washer. Before closing, check the wiring nuts, bolts and other components in detail and confirm that they are intact and free from looseness or damage. There are protective covers at the terminals.

5. Before use, check and confirm that the primary and secondary wires are connected correctly, the input voltage is in accordance with the nameplate of the electric welding machine, and the type and scope of the welding current of the spot welding machine are known. After connecting the power, it is strictly forbidden to touch the live parts of the primary circuit. Protective covers must be installed at the primary and secondary wiring.

6. When moving the welding machine, cut off the power supply. Do not move the welding machine by pulling the cable. When there is a sudden power failure during welding, the power should be cut off immediately.

7. When welding non-ferrous metals such as copper, aluminum, zinc, tin, lead, etc., it must be carried out in a well-ventilated place. The welding personnel should wear gas masks or breathing filters. Spot welding

8. When multiple welding machines are used collectively, they should be connected to the three-phase power network to balance the three-phase load. The grounding devices of multiple welding machines shall be connected by grounding electrodes, and shall not be connected in series.

9. Welding is strictly forbidden on the pressure pipelines in operation, containers with flammable and explosive materials, and stressed components.

10. When welding the preheating parts, a baffle shall be provided to isolate the radiant heat from the preheating weldment.
