. With high frequency up to 200KHZ, the quenching thickness can be controlled lower than 1～ 1.5mm. 2. IGBT module and Inverting technologies of third generation been used; Higher reliability and lower maintenance cost. 3 . Duty cycle, continuous working is allowed at maximum power output. 4. Constant current or constant power status can be selected accordingly to achieve higher heating efficiency; 5 .Display of heating power and heating current and oscillating frequency; 6 .Simple to install, Installation can be done by unprofessional person very easily; 7. Light weight 8 .Advantages of the model 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; 9 .The separated models are designed to fit the dirty surrounding of some cases.
