Advantages applications of models with Timer function:

1. Heating power, retaining power, heating time, retaining time can be preset adjusted, this makes it possible to control the heating curve heating time.

2. It is suitable to use in the repeated heating or high speed heating of small parts;

3. When using in brazing, with proper timing parameters, rapid heating retaining can be achieved to keep the temperature while the brazing material is melted then to let the brazing material spread smoothly to form good joint

Advantages applications of separated transformer:

1. In this series machine, the high frequency transformer is separated from the generator, with 6 meters connecting cable at least.


2. It is suitable to use in the dirty or corrosive surroundings, the generator can be put in a clean space to increase the reliability.

Working theory structure

Inside these series machines, IGBT module our third generation inverting control technology has been used, that is the soft dual control inverting technology. In this technology, output power frequency can be controlled adjusted separately, IGBT module soft switching control technology are used in the high frequency switching circuit to control the output power. In the inverting circuit, the IGBT frequency tracing circuit is applied to achieve high speed accurate soft switching control. The adoption of new technologies not only improves the quality reliability of the machine,but also solve the technology problem on large power induction heating machine makes it possible to work 100% duty cycle.


In DD-70 series machines, oscillating cap is connected to the primary coil of the high frequency transformer, due to the low cost of this structure, SP-70B is characterized with low price.

In DD-70 series machines, series oscillating circuit is applied, through high frequency transformer, low voltage high current power is output to go through the induction coil.
