  • Page 8 page for this) If the machine is a single phase machine then each KVA would require around 4.6 Amps of current. That means if input KVA of the machine is 5 KVA, then it would draw 23 Amps at full load If the machine is a three phase machine then each KVA would require around 1.4 Amps of current.

    5. Working Principle Block Diagram These power sources are used for various types of welding and they are based on IGBT inverter Technology. In these types of machines input supply is first converted in to DC by a rectifier circuit. The rectified voltage is then filtered and fed to an inverter section.
  • Page 11 Block diagram with waveforms at different stages is given below for reference : Different types of power sources are available for welding and most commonly used are as under Constant current (CC) power source Constant Voltage (CV) power source CC/CV power source Please refer to the below chart for process-wise recommended power source types Process Power source type...
  • Page 12 Constant Current (CC) type power source Constant current characteristics is also called as drooping characteristics. Typical V/I curve of such power source is shown below. Here the current remains stable even if the arc length varies. When there is change in arc length, change in the voltage is more when compared to change in current and hence they are called constant current type power source Relationship between the voltage and current for different process in CC type power source is as under...
  • Page 13 Relationship between the voltage and current for different process in CV type power source is as under GMAW: V = I * 0.05 + 14 FCAW: V = I * 0.05 + 18 Note: Some power source have both CC and CV characteristics. The explanation given above is general and the capability of the machines depends on the model number of the machine purchased by you.
