Maintenance process of spot welding machine

2021-10-19 09:22

The medium frequency DC spot welding machine shall be provided with reliable grounding protection. The parallel installation distance of multiple equipment shall not be less than 3m. Inspection shall be carried out before operation. The pressure mechanism of the welding machine shall be flexible, the fixture shall be firm, and the gas-liquid system shall be free of leakage.
 
Before welding, the corresponding parameters and secondary voltage should be adjusted according to the workpiece to be welded, the cooling water should be discharged regularly, the contact points and electrodes of the circuit breaker should be polished, and all connecting bolts of the secondary circuit should be tightened regularly.
 
Regularly inject lubricating oil into the rotating conductive part. The maintenance of the welding arm and electrode lies in that the welding arm and electrode will pass a large current when they work. If a thicker oxide layer accumulates on the surface, it will cause poor resistance contact and eventually cause the solder joint to be unsightly.
