Compared with the AC welding machine, the intermediate frequency welding machine can reduce the consumption of electric energy. The transformer of the same weight can output a large amount of kinetic energy. It can be easily used with large automatic welding tongs, and is suitable for welding thick workpieces and metals with high conductivity.

In semi-automatic installations, one intermediate frequency welding transformer can replace many low frequency transformers, reducing the parallel connection of secondary circuits. If the one-piece manual welding tongs weigh more than 80 to 90 kg, this type of transformer is also suitable. For example: the production of small batches of cars/vans and the production of small-scale experimental machinery and equipment.

The intermediate frequency welding machine can reduce interference in the secondary circuit with a large open area: the welding current is DC, and when there is an inductive/magnetic material in the secondary winding, it is not easy to affect the welding. Balance the load of the power supply equipment: the medium frequency inverter spot projection welding machine uses a three-phase power supply and can store kinetic energy. It is more adaptable to the fluctuation and voltage drop of the power grid: part of the kinetic energy is stored by the inverter and then supplied to the load, replacing the method of directly supplying power to the load from the power grid.

More accurate and fast current control of intermediate frequency welding machine: Compared with low frequency system, it can analyze a large number of parameters more accurately. Faster to set current: IF can adjust welding current up to 20 times faster than conventional techniques. The process is more reliable: most of the metals that use solder mask use DC welding for better results. IF systems are generally more reliable than traditional techniques and can prevent some of the damage that would otherwise be caused by thyristor-based systems. Reduce operating costs, including saving each point of welding kinetic energy and reducing welding cycle.
