What about Lang Xian cold welding machine?

According to the related information of the top ten brand networks, Shanghai Langxian Electromechanical Equipment Co., Ltd. is the largest company in cold welding machine, and its cold welding machine is quite good, and its repair speed is faster than that of the general cold welding machine company. After warm welding, it has no good firmness, close color difference and no hard spots, so it is not bad.

Cold welding machine, known internationally as ESD, was developed by experts from the former Soviet Union by applying the circuit principle similar to that of EDM. At the beginning, the maximum coating thickness of the processing machine was only about 30μm, which could not meet the repair needs.
