The application of spot welding machines greatly improves the appearance and internal quality of welded parts, ensures quality stability and reduces labor intensity, improves the working environment, reduces manual welding skill requirements and production costs, and enhances production efficiency. However, while using the spot welding machine, attention should also be paid to the following precautions after welding:

When the welding machine stops working, the power and gas sources should be cut off first, and then the water source should be turned off to remove debris and welding slag splashes.

2. If the welding machine is not used for a long time, anti rust oil should be applied to the unpainted moving parts. Heating with electricity for 30 minutes every month. The replacement of the thyristor should also be preheated for 30 minutes, and the preheating of the control box for normal operation should not be less than 5 minutes.
