Electric welding machine safety technical operation procedures

First, the general considerations for the use of electric welding machine:

1. The welding machine should be placed as close as possible to the welding work site, and the welding machine should be reliably protected from damage and unclean debris.

2. The housing of the welding machine must not be installed with a reliable grounding or zeroing device.

3. When multiple single-phase welding machines are used at the same time, they should be evenly distributed among the phases of the three-phase line.

4. The moving wire used in the welding machine should be soft thick rubber line and should have sufficient capacity to prohibit the use of poor insulation or bare wires.

5. When connecting the conductor and tightening the wiring nut in the output side circuit, it should be carried out after the unit power supply is disconnected.

6. In the rainy days, the welding work shall not be carried out in the open air. If there are special circumstances, reliable rainproof and electrical safety measures shall be taken before the operation can be carried out.

7. The components and internal parts of the unit should be kept clean or cleaned before use.

8. According to the technical requirements of welding, the type of welding machine is selected correctly.

Second, preparation and testing matters before welding work:

1. Check if the connection points of all the wires in the input side and output side circuits are reliable and the wiring is correct.

2. The ground wire should be in good contact.

3. The insulated handle of the electric welding handle should be good.

4. Detect whether the charged body of each connector on the input side is exposed, if it should be covered immediately.

5. Check the wire insulation rubber for damage.

6. Before welding in a closed environment, confirm whether there is flammable gas in the surrounding environment. If ventilation is required, confirm that the gas concentration is lower than the specified value to prevent gas explosion.

7. Before the welding in a relatively closed environment, ventilation and exhaust measures are required before operation.

Third, should pay attention to the welding work:

1. Always pay attention to the temperature of each component of the welder, and should not exceed the value specified on the nameplate.

2. Always pay attention to the unit and the wire, and should not be subject to any mechanical damage.

3. Wear protective shoes and protective clothing such as masks during work to prevent electric shock and arcing.
