Main applications characteristics:
DD-25 series is suitable for the heating of small metal parts, for example, （1）brazing of machining tools （2）Brazing of diamond tools （3）Heat treatment of small parts （4）Melting of gold, silver, copper, brass of little amount （5）Melting of steel stainless steel of little amount （6）Brazing of copper & brass tube connectors in air conditioner manufacturing factories so on. (7) Brazing of electrical kettle bottom.
DD-25 series machines are characterized with simple structure, high reliability low price, are one of the most popular models have been used widely in every areas of metal heating.
Advantages applications of separated transformer of DD-25II:
1. In DD-25II 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.
3. With the small size light weight of the separated transformer, it is convenient to use in the production line easily assembled inside the machinery or moved mechanism.
Working theory structure:
In DD-25 series machines, series oscillating circuit is applied, through high frequency transformer, low voltage high current power is output to go through the induction coil. DD-25 series machines are the first models developed in our company, using IGBT module our first generation inverting control technology, the machines are featured with simple structure, high reliability low price, they are easy to use to repair, are now the most widely used machines both in China abroad.
