The safe operation of lithium battery automatic spot welding machine is a matter that every skilled worker should memorize. On the premise of improving welding efficiency, make relevant safety plans, which will not only improve welding efficiency but also ensure personal safety. Our company will introduce relevant safety knowledge to you, hoping to help you learn more welding knowledge.
1. Oil stains and dirt must be removed before work, otherwise the service life of the electrode will be severely reduced and the welding quality will be affected.
2. After the automatic spot welding machine is energized, the electrical equipment, operating mechanism, cooling system, gas circuit system and body shell should be checked for leakage.
3. Before starting the automatic spot welding machine, first turn on the transfer switch of the control circuit and the small switch of the welding current, install the position of the knife of the series adjustment switch, connect the water source, the gas source, and the adjustment buttons on the control box, and finally Turn on the power and start working.
4. The electrode contacts should be kept clean and smooth, and can be trimmed with a fine file or emery cloth if necessary.
5. The bearing hinge of the automatic spot welding machine and the piston and lining ring of the cylinder should be lubricated regularly.
6. When the automatic spot welding machine is working, the gas circuit system and the water cooling system should be unblocked. The gas must be kept dry and should not contain moisture. The drainage temperature should not exceed 40°C, and the drainage flow can be adjusted according to the season (smaller in winter and larger in summer).
7. When the automatic spot welding machine stops working when the temperature is below 0 °C, the water in the cooling system must be blown out with compressed air to prevent the pipeline from freezing and cracking or blocking.
8. The working stroke of the upper electrode is realized by adjusting the two nuts under the cylinder block. After adjustment, it must be tightened.
9. The electrode pressure can be adjusted by rotating the handle of the pressure reducing valve according to the requirements of the welding specification.
10. Avoid damage to the ignition tube and selenium rectifier, and it is strictly forbidden to increase the fuse in the ignition circuit.
11. When the load is too small and the arc in the ignition tube cannot occur, it is strictly forbidden to close the ignition circuit of the control box, because the ignition circuit cannot be shunted by the arc at this time, so that the ignition circuit has a large current during the closing period. By easily damaging the ignition tube and selenium rectifier.
12. The circuit device of the control box is more complicated, and attention should be paid to protect the circuit facilities from being damaged by touching. When the temperature is low in winter, the thyratron and ignition tube are not easy to ignite. The indoor temperature should not be lower than 15℃.
13. After the automatic spot welding machine stops working, the sundries and welding slag splashes must be removed.
14. When the automatic spot welding machine stops working, the power supply and gas source should be cut off first, and finally, the water source should be turned off.
15. If the automatic spot welding machine is out of use for a long time, anti-rust grease must be applied to the moving parts that are not painted to prevent the parts from rusting.
16. If the control box is out of use for a long time, in order to prevent moisture immersion, it should be heated for 30 minutes every month. If the thyratron is replaced, it should also be preheated for 30 minutes. The preheating of the control box in normal work is not less than 5 minutes, otherwise it is easy to cause reverse arc or runaway.
