250 double voltage welding machine on two power lines, how to meet the voltage of 380?,
If it is determined to be double voltage welding machine, two power lines: 101 fire is 220V, two are connected to the FireWire, that is, 380V.
Select the 380V file terminal and the center column, and connect the 380V to any of the two phases.
If it is determined to be double voltage welding machine, two power lines: 101 fire is 220V, two are connected to the FireWire, that is, 380V.The main component of the electric welding machine is a step-down transformer. The two ends of the secondary coil are welded workpieces and welding electrodes. When the work is done, the arc is ignited, and the electrode is fused into the gap of the workpiece at the high temperature of the arc. As the core of the welding transformer has its own characteristics, it has the characteristics of a sharp drop in voltage, that is, when the electrode is ignited, the voltage drops; when the electrode is stuck short circuited, the voltage is sharply decreased.
