The role of current during projection welding with medium frequency spot welding machine

Medium frequency spot welding machines generally require less current than single point current for bump welding of workpieces of the same material and thickness. But you must ensure that the current setting can melt the bumps before the bumps are completely crushed. That is to say, excess metal ... Read More

Is the cooling system of medium frequency spot welding machine important?

Due to the fast heating speed, generally 1000HZ, the medium frequency spot welding machine generates heat quickly. If the heat cannot be taken away in time, a large amount of welding waste heat will be generated in the electrodes and conductive parts, which will be superimposed time and time agai... Read More

Is it important to grind the electrodes of medium frequency spot welding machines?

When the medium frequency spot welding machine is working, due to long-term welding, countless impacts of instantaneous high current and countless collisions of hundreds of kilograms of pressure, the electrode end surface changes greatly, which will cause poor welding consistency. During welding,... Read More
