Does the hot cooling water of spot welding machine affect the welding effect?

spot welding machine is hot during welding, continue to use the hot cooling water for cooling, it must reduce the cooling effect and affect the welding. The reason why

spot welding machine needs to be cooled is that the whole circuit generates heat due to large current flowing through it for a long time, including controller, transformer, copper bar, cable, grip rod, electrode, etc. The workpiece also transfers heat to secondary connections such as electrodes during the heating process.

controller, continuous overheating of the transformer will affect the service life of the component or even burn out, overheating of the electrode will affect the service life of the welding head, and the residual heat will also affect the welding effect. Usually, the electrode will be stuck, the electrode will wear too fast, the current time will not change, and the energy will suddenly increase. The cooling of the

spot welding machine is also related to the welding beat. Of course, this is related to the structure of the spot welding machine, the load rate, etc. Excluding other influencing factors, the faster the welding beat, the higher the cooling requirement. The influence of

cooling water heating on welding depends on the whole spot welding machine structure, welding effect requirements, welding beat and other factors. It is recommended to replace the circulating cooling water tank with a larger volume of water flow when the cooling water is hot, and use an ice water machine with refrigeration function for cooling when necessary.
