These series are suitable for many applications, for example,

 (1)Heat treatment of gear and shaft

(2)steel and stainless steel screw coating 

(3)floating melt for institute or college research 

(4)tiny or powder material melting 

(5)copper joint brazing and so on.
Due to the adopting of our third generation inverting control technology, SPG-10-I and SPG-20B series machines are acterized not only with high power and high frequency up to 250KHZ output, but also with high reliability on the condition of normal IGBT module.

 

Advantages and applications of models with Timer function:
   1. Heating power, retaining power, heating time, retaining time   can be preset and adjusted, this makes it possible to control the heating curve and 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 and retaining can be achieved to keep the temperature while the brazing material is melted and then to let the brazing material spread smoothly to form good joint.


Advantages and applications of separated transformer:
   1. In these three series machines, the high frequency transformer is separated from the generator, with 2 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.
  3. With the small size and light weight of the separated transformer, it is convenient to use in the production line and easily assembled inside the machinery or moved mechanism.

 

Working theory and structure
    In These series machines, series oscillating circuit is applied, through high frequency transformer, low voltage and high current power is output to go through the induction coil. The main oscillating structure is as follows:

   


    Inside These series machines, IGBT module and our third generation inverting control technology has been used, that is the soft and dual control and inverting technology. In this technology, output power and frequency can be controlled and adjusted separately, IGBT module and soft switching control technology are used in the high frequency switching circuit to control the output power.  In the inverting circuit, the IGBT and frequency tracing circuit is applied to achieve high speed and accurate soft switching control. The adoption of new technologies not only improves the quality and reliability of the machine,but also solve the technology problem on large power induction heating machine and makes it possible to work 100% duty cycle.
    Inside the These series machines, oscillating cap is connected to the secondary coil of the transformer, so the voltage on the primary coil of the transformer is low and problems caused by high voltage such as sparks and insulations are solved thoroughly to increase the reliability and quality of the machine. At the same time, the transformer is light and small sized with low energy consuming.
