Welding Inverters

We are the manufacturer, supplier and exporter of Welding Inverters.

welding inverter

Process:

An inverter used in the welding application functions as below:

  • AC Line voltage is taken as the input to the welding equipment
  • It is suitably RFI/EMI filtered and rectified
  • This rectified voltage is filtered to make it pure DC
  • This DC voltage is taken as the input to the switching device through a high frequency power transformer
  • As this switching frequency is very high the size of this transformer becomes very small compared to its counter parts
  • The transformer output is suitably stepped down
  • This stepped down AC voltage is again rectified using fast recovery diodes
  • This output is used for welding
  • Suitable controls and feedback techniques are used
