Coffee, which brand of optical fiber welding machine is good? Has anyone ever used a Jixing welder?

Now the domestic market is divided into two groups: imported machines and domestic machines. The imported machines are represented by Fujikura and Sumitomo, and the domestic machines are represented by Nanjing Geelong and 4 1. In addition, DVP and Jiangsu Jixing have also done a good job in domestic welding machines. By the way, Master Wang of our engineering team just bought the Taijixing FX39 machine last month. Don't say that this FX39 trunk machine can be compared with Fujikura in appearance, welding heating time, core alignment technology and battery capacity.
