1、 The welding effect is good, and the time adjustment resolution of the intermediate frequency spot welding machine can reach 0.25ms (4kHz inverter frequency), with high control accuracy. The response speed of the feedback control of the intermediate frequency spot welding machine is significantly accelerated, and the output stability is good. The output current of the intermediate frequency spot welding machine is pulsating DC, and under the action of the circuit inductance, it is continuous DC output, with high thermal efficiency and stable welding heat input.

2、 The welding is well formed, and the intermediate frequency spot welding machine has DC output, centralized heating, and shortened welding time. Therefore, it has excellent results in strong standard welding, with first-class seamless effect, and can directly weld computer cases and other high-end welding.

3、 Energy saving and environmentally friendly, the transformer of the intermediate frequency spot welding machine operates at a high frequency (1-4kHz) with minimal loss, and the DC output improves the power factor, resulting in significant energy-saving effects.

4、 The structure of the equipment is reasonable and easy to install, the transformer of the intermediate frequency spot welding machine is greatly reduced, and the equipment is relatively lightweight.
