ZD-HJ-K250 is an intelligent electrothermal fusion welding machine developed by our company for the emerging market of K-type pipe welding. It mainly uses inverter technology to convert 50HZ/60HZ industrial frequency to high frequency, then reduces voltage and adjusts current. Through pulse width modulation (PWM) technology, a powerful DC welding power supply can be generated. The whole machine is compact in design, small in size, light in weight, and easy to move. At the same time, it adopts a dual voltage system, without the need for a conversion key, it can directly connect to 220V or 380V power supply for intelligent conversion, providing greater convenience for users. The launch of this product has solved the problem of K-type pipe welding and has won the favor of customers.
