Smelting oven/ melting pot

Heat melting pot DD-04

 

Product features:

 

1.Adopt imported high-quality IGBT solid power module advance frequency conversion technology, the quality of the device is improved greatly.

2.The heating,retain current time can be set adjusted.

3.Simple convenient installation, can work after connecting to 220V power, water inlet water outlet. Professional installation is not required.

4.Small shape,light weight,simple operation, can be learned within several minutes.

5.Contain the multi-level protection display such as overvoltage,overcurrent,overheat underwater.

 

 

Main applications:

Woodworker uses hard alloy sawing blade welding tooth.The mental cutting uses had alloy saw blade welding tooth.

 

Advantages comparing with resisitor welding tooth:

 

1.High-efficiency rapid welding tooth, 1-5 seconds for each tooth.

2.Good repetition,each tooth has good repetition performance.

3.Rapid equal heating can effectively prevent partial overheating of the saw tooth from brittleness cracking prevent non-full welding from losing tooth.

4.High-ragidity saw tooth, saome saw blades can not be welded by resisitor.

Main characteristics application:

 

DD-04 series is suitable for the heating of small metal parts, for example:

 

(1)brazing of tips of wooden saw

 

(2)Heat treatment of small parts

 

(3)Melting of gold, silver, copper, brass steel of little amount.

 

DD-04 series machines are characterized with simple structure, high reliability, 250KHZ frequency low price, are one of the most popular models have been used widely in every areas of metal heating;

 

 

Working theory structure

In DD-04 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-04 series machines are the first models developed in our company, using MOSFET components 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.

 

Advantages applications of Timer function of DD-04:

1. Heating power, retaining power, heating time, retaining time cooling 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.
