The MZ7-1250 hot-wire SAW welding machine is developed based on the the original submerged-arc welding machine. As its wire is preheated before welding, its molten depth will be deeper, and welding performance is higher and better.

Our all-digital AC/DC square-wave SAW machine is developed on the DC SAW machine adopting the inverter technology twice, with wonderful welding result. The details is: the 3-phase 380V/50Hz power will change into HF AC after the filtration of the power frequency rectifier and role of inverter. And over high-frequency transformation and rectification, feedback control of output signal, the smooth and continuously adjustable DC will be got. After the second inversion, the DC will be changed into low-frequency AC for automatic welding of work pieces.
