As we all know, when using spot welding equipment, we must first be familiar with its performance and correct operation methods to ensure our own personal safety. In order to improve work efficiency and product quality, in use, we will come into contact with a lot of things that need to be paid attention to. The following things need to be paid attention to, so let us understand together.

　　1. For on-site use, a rain-proof, moisture-proof, sun-proof shed should be set up, and corresponding fire-fighting equipment should be installed.

　　2. Oil, wood, oxygen cylinders, acetylene generators and other flammable and explosive materials shall not be stacked within 10m of the welding site.

　　3. Welding operations and cooperating personnel must wear labor protection equipment as required. Safety measures must be taken to prevent accidents such as electric shock.

　　4. The copper plate connected to the secondary tap should be pressed tightly, and the terminal should have a washer. Before closing, check wiring nuts, bolts and other components in detail, and confirm that they are intact. There is a protective cover at the terminal.

　　5. Before use, check and confirm the initial. The secondary line is connected correctly, the input voltage is in accordance with the nameplate of the welding machine, and the type and scope of application of the welding current of the welding machine are known. After turning on the power, it is strictly forbidden to touch the live parts of the primary circuit. The primary and secondary wiring must be equipped with protective covers.

　　6. When moving the welding machine, cut off the power supply and do not move the welding machine by dragging the cable. In the event of a sudden power failure during welding, the power supply 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 a gas mask or breathing filter.

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

　　9. It is strictly forbidden to weld pressure pipes, flammable and explosive containers and stressed components during operation.

　　10. When welding the preheating parts, a baffle should be set to isolate the radiant heat generated by the preheating weldments.
