█ Using high frequency control technology, the control precision and speed of
    temperature is significantly higher than AC welder.

█ Clear and intuitive large screen LCD, can real-time waveform display dynamic
    heating temperature, heating time.

█ Real-time list shows the key parameters of the last 5 times the heating temperature , to
    facilitate the analysis of the heating process for quality management.

█ Thermocouple wire disconnect, reverse and aging alarm

█ Store 3 1sets of welding schedules

█ 9 step heating function.

█ Output 3 point temperature signals in the heating process.

█ Have heating speed regulating function to deal with different welding head.

█ Three methods for starting ( room temperature, preheat and external analog input ).

█ Used in a variety of flexible circuit boards, metal wire, enameled wire or hang tin
    welding of hot pressing. And heating of plasticity plastic joint.
