In modern industrial production, medium - frequency inverter spot welders, as key equipment, are widely used in automotive, electronic, home appliance, and many other fields. So, how do they achieve efficient spot welding?


Spot welding essentially involves heating metal joints to a molten state and then applying pressure for them to cool and solidify. Conventional spot welding equipment often relies on DC motor welders. But with the growing demands of industrial production and the pursuit of higher efficiency, medium - frequency inverter spot welders have emerged and shown significant advantages.


Medium - frequency inverter spot welders convert low - frequency AC power to high - frequency power, boosting electrical energy to hundreds of thousands of volts. After partially heating the metal joint, they apply precise pressure to instantly melt the joint and maintain it for a certain time. By strictly controlling current and heating time, they ensure proper melting of the joint for high - quality spot welding.

In terms of structure, medium - frequency inverter spot welders mainly consist of three parts: the rectifier transformer main circuit, the control box, the secondary circuit of the power transformer, and the welding transformer. The rectifier transformer main circuit includes a step - up transformer, a rectifier bridge, and DC components, which convert AC to DC. The secondary circuit of the power transformer, composed of a power transformer, a post - capacitor, and an output plate, controls power output for stable energy release. The welding transformer converts high - voltage electricity to low - voltage suitable for spot welding, offering precise power support.


When using a medium - frequency inverter spot welder, operators need to set welding parameters like current, heating time, and pressure based on the metal's material and thickness. Then, clamp the electrode to the metal piece and start the machine. Spot welding is done instantly when the two electrodes contact.


In summary, medium - frequency inverter spot welders are crucial in industrial production due to their high efficiency and precise welding quality. They boost production efficiency and product quality, bringing tangible benefits to manufacturing enterprises.
