1. Frequency stability: the adoption of international industrial band 40.68MHz conforms to the international and Chinese national standards, and effectively improves the processing speed. The processing scope is extended to P.V.C., real leather, artificial leather, EVA, PEVA, EVOH, PU, PE, PET.

2. Patented spark protector: a new design, when the spark is produced, the special circuit can automatically cut off the high frequency in a millionth of a second, protecting the mould and the workpiece in good condition.

3. The machine is equipped with a patented design of overcurrent protection device, so that the current can be automatically controlled in a safe range to protect the valve and rectifier.

4. Protection of ac contactor: patented technology that is unique and can eliminate contact spark of ac contactor to prolong the service life of ac contactor and reduce the cost of use
