-Synchronous automatic frequency tracking system

（1）The high and new technology of synchronous automatic frequency tracing realizes the synchronization of the increase/decrease frequency and output frequency of the welding head.

-Voltage FEEDBACK function

（1）Without AVR function, it can maintain the amplitude of the original voltage in the range of 180-240v. The stability of equipment and welding effect can be guaranteed.

-Phrase "function

（1）Can measure overload voltage and overload current deviation, such as the occurrence of problems can be cut off in time to protect the generator output.

-SOFT START function

（1）Adopt perfect soft start function to effectively remove the damage caused by impact on welding head during starting vibration and eliminate the fault during welding head and ultrasonic vibration (adjustable range: 10mses~200msec).
