400V, 480V & 575V SINGLE VOLTAGE * Slow Blow Fuse
*The three-phase supply voltage is connected to a circuit breaker and then to a six-pulse rectifier
circuitry and a radio noise suppression module. The AC voltage is connected to a step-down
transformer to power the welder. The AC welding voltage is first rectified to create a DC welding
current. The control logic measures the welding voltage and welding current. It also makes the
inverter create the suitable welding characteristics. The auxiliary transformer steps down the
input voltage to 48V center tapped. This transformer powers the cooling fan and the control
logic.
