For two-phase 380V electric welding machine, it is said that the voltage difference between two phases is 380V when connecting two phases, but the control circuit is 220V. How can it also connect two phases?

A: We specialize in the production of welding machines
Generally speaking, when two-phase 380V welding machine is connected, both wires are connected to 380V. The control circuit is 220V, which is generally called single-phase 220V
