Secondary choke L002• The secondary choke reduces the ripple contents of secondary current• To achieve better welding properties L002 is constructed so that choke saturates in certain voltage and current values10.2. Shunt resistor R002• Secondary current is measured with the shunt resistor10.3. Output RFI filter unit RC001• Capacitors C001 to C005, varistor R003 and two power resistors forms a radio frequency interference (RFI) unit to re-duce radio frequency interference.10.4. Machine output terminals X002, X003 and X004• Machine has two (+) terminals X002 and X003 and one (-) terminal X00410.5. Auxiliary transformer T002• The auxiliary transformer (T002) is a toroid transformer. It has 400 V primary and 38V and 20V secondary.• 20V secondary supplies the control card A001 circuitry and the fans M001 and M002• 38V secondary voltage is rectified with auxiliary rectifier (G003) to 50V dc –voltage10.6. Auxiliary rectifier bridge G003• 50V dc voltage supplies the serial communication bus and devices that are connected to it
