Medium frequency spot welding machine failure cause detection

After the intermediate frequency spot welding machine has been installed and debugged, after a period of operation, some minor faults may occur due to the operator and the external environment. The following is a brief introduction to several aspects of possible faults. 1. The controller does no... Read More

Detailed explanation of medium frequency spot welding machine transformer knowledge

The power of the medium frequency spot welding machine transformer load is certain, and the power is proportional to the current and voltage. Lowering the voltage will increase the current. The spot welding machine is a special working method of the step-down transformer. The medium frequency sp... Read More

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...

Medium frequency spot welding machine spot welding nut technology and method

The welding nut of the medium frequency spot welder is the realization of the projection welding function of the spot welder. It can complete the welding of the nut quickly and with high quality. However, several problems need to be solved during the projection welding process of the nut. There s... 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
