Correct operation process of commutator spot welding machine

    The correct operation process of commutator spot welding machine:

    1. Before operation, the two electrodes should be degreasing. When the power is turned on, there should be no leakage of the body shell.

    2. Before starting, turn on the switch of the control circuit and welding current, adjust the number of poles, and then connect to the water source and air source, and turn on the power.

    3. After the welding machine is energized, check the electrical equipment, operating mechanism, cooling system, pneumatic system and body shell for leakage. The electrode contacts should be kept clean. If there is a leakage, it should be replaced immediately.

    4. During operation, the air path and water cooling system should be unblocked. The gas must be kept dry. The temperature of the water should not exceed 40 degrees, and the drainage volume can be adjusted according to the temperature.

    5. It is strictly forbidden to increase the fuse of the ignition circuit. When the load is too small, the arc cannot occur and the ignition circuit of the control box cannot be closed.

    6. When the control box is not used for a long time, it should be heated for half an hour every month. The replacement thyratron should be preheated for half an hour. The warm-up time of the normal control box should not be less than 5min.

    7. Welding personnel must wear personal protective equipment in accordance with regulations and take safety measures to prevent electric shock, falling from height, poisoning and fire accidents.

    8. The welding machine operated on site should be rainproof, moisture-proof and sun-proof, and corresponding fire-fighting equipment should be installed.

    9. When welding or cutting at high altitude, safety belts must be fastened, and fire prevention measures should be taken around and under welding.

    10. When removing welding slag, wear protective glasses and avoid the splashing direction of welding slag.

    11. For welding operations in rainy weather or in damp areas, the operator should stand in an insulated place and wear insulated shoes.
