Features:
1. MOSFET and inverting technologies of first generation been used;
2. Oscillating frequency can be high to 250KHz, fitted for rapid heating of tiny metal parts;
3. Simple structure and light weight;
4. Simple to operate, a few minutes is enough to learn it;
5. Simple to install, installation can be done by unprofessional person very easily;
6. Advantages of the model UF-04A with timer: The power and the operating time of the heating period and the retain period can be preset respectively, to realize a simple heating curve, this model is suggested to use for batch production to improve the repeatability.

Application recommended-----brazing of the carbide blades of the circular saw
Advantages over resistance brazing:
1. Quick brazing, 1-5seconds for one blades
2. Good repeatability for each blade;
3. Quick and even heating, preventing blade breaking caused by partial heating;
4. Effective brazing for high standard and high hardness blade sections, which is impossible for resistance brazing.
