Working principle of medium frequency inverter spot welding machine

intermediate frequency inverter spot welding machine is a kind of resistance welding, and it is also the mainstream welding equipment in the spot welding machine market at present. The intermediate frequency inverter spot welding machine combines intermediate frequency resistance welding rectifier technology and power inverter technology, and has made great progress in welding performance and welding efficiency. Wilda's welding equipment has a good reputation in the industry and has been well received by customers.

Some people will ask whether the design and development of the intermediate frequency inverter point machine will be very complicated, whether the operation will be unstable, whether the maintenance frequency will increase, and whether the use cost will not increase. Compared with the traditional frequency inverter spot welding machine, the structure is simpler, the operation is more stable, and the performance is more superior. The working principle of

intermediate frequency inverter spot welder:

1, rectifying, filtering and inverting 50HZ alternating current into 800-2000HZ intermediate frequency rectangular wave through rectifier;

2, step-down to low voltage alternating current through intermediate frequency transformer;

3, through single-phase full-wave rectification to low voltage direct current;

4. Weld the workpiece through integrated spot welding tongs or fixed spot welding machine.
