Why is the medium frequency spot welder so easy to use?

1) The transformer of the medium frequency inverter spot welding machine is small in weight and volume, and the input power is low, which is convenient to use the transformer to connect the welding tongs. The traditional power frequency welding machine needs a robot with strong load capacity when it is used on the automatic line, while the transformer of the intermediate frequency inverter spot welding machine can reduce the load of the robot to a great extent.

2) The welding current of the medium frequency inverter spot welding machine is a rectangular wave, close to DC, without obvious peak current, the size of the nugget expands steadily, there is almost no spatter, the welding quality is stable, and the thermal efficiency is high. Compared with the power frequency welding machine, the welding current of the intermediate frequency inverter spot welding machine can be reduced by 40%, which greatly prolongs the service life of the electrode.

3) The medium frequency inverter spot welding machine is suitable for welding various materials and dissimilar metals, such as aluminum alloy, stainless steel, high-strength steel plate and other materials. In addition, the welding quality of galvanized sheets and ordinary multi-layer boards is much higher than that of power frequency welding machines.

4) The medium frequency inverter spot welding machine has the characteristics of three-phase load balance, and the power factor is as high as 0.9 or even higher.

5) The current of the intermediate frequency inverter spot welding machine can reach the set value faster, the parameter analysis is more accurate, the response speed is only 5% of the power frequency AC spot welding machine, and the welding quality control is more accurate.
