How does the current of the medium frequency spot welding machine increase?
In order to compensate for the reduction in welding current caused by electrode grinding, the controller of the medium frequency spot welder provides a current increasing function. Users can set up to 9 incremental segments according to actual conditions. The following parameters are involved in ...Read more -
Detailed explanation of medium frequency spot welding machine electrodes
Intermediate frequency spot welding machine electrodes generally use chromium zirconium copper, or beryllium bronze, or beryllium cobalt copper. Some users also use red copper for welding, but only in small batches. Since the electrodes of spot welders are prone to heat and wear after working for...Read more -
What is the impact of welding time on the projection welding function of medium frequency spot welding machine?
The welding time plays an important role when the medium frequency spot welding machine performs projection welding. If the welding time is too long or too short, it will have a great impact on the welding quality. When the material and thickness of the weldment are given, the welding time is de...Read more -
How is the circuit of the medium frequency spot welding machine constructed?
The intermediate frequency spot welding machine includes a controller and an intermediate frequency transformer. The output terminals of the three-phase bridge rectifier and LC filter circuits are connected to the input terminals of the full-bridge inverter circuit composed of IGBTs. The AC squa...Read more -
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 -
How does the pressure change during projection welding with a medium frequency spot welder?
When the medium frequency spot welder performs projection welding, the welding pressure is very critical. It is required that the pneumatic part has good follow-up performance and the pneumatic can deliver pressure stably. The electrode force of projection welding should be enough to completely c...Read more -

Will the hot cooling water of the energy storage spot welding machine affect the welding effect?
If the cooling water of the energy storage spot welding machine becomes hot during welding, continuing to use the hot cooling water for cooling will definitely reduce the cooling effect and affect the welding. The reason why the energy storage spot welding machine needs to be cooled is because a ...Read more -
Design considerations for welding jig and device of capacity discharge spot welder
The design of welding fixtures or other devices must pay attention to, because the general fixture is involved in the welding circuit, the material used in the fixture must be non-magnetic or low-magnetic metal to reduce the impact on the welding circuit. The fixture structure mechanics is simpl...Read more -
The structure of the nut electrode of the medium frequency spot welding machine
The nut electrode of the intermediate frequency spot welding machine has a lower electrode and an upper electrode. The lower electrode positions the work piece. It generally holds the work piece from bottom to top and has a positioning and fixing function. The work piece needs to be pre-opened at...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
