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

Check out our Welding Inverters features, advantages, specifications, applications & scope of supply

Features:

  • Used for Welding Process – Plasma Arc Welding, TIG Welding, MIG Welding, PTA Welding, Hard Banding
  • Latest PWM technology using IGBTs
  • Light weight & compact – 80% less weight compared to conventional machines
  • Saves Power Cost – No Load Input of 0.2 Amps results in substantial savings in power cost
  • Less Power Consumption – On load power consumption of 50% lesser than conventional machine
  • Dynamic – Designed to work under wide voltage fluctuations protected against Over Voltage, Under Voltage, Single Phasing, and Over Heating with Indications
  • In-built selectable pulsing of 1 to 10 Hz of output current
  • Reliable Electrode Ignition – High OCV & controlled start current ensures reliable electrode ignition
  • Spatter Free Welding – Fast regulation speed & excellent dynamic properties ensures spatter free welding performance even with difficult electrodes
  • Suitable for thin Sheet Welding – Reliable start even at 3 amps in TIG without any surge in welding current makes it suitable for thin sheet welding
  • Standard inbuilt HF with fully fledged pulsing models
  • Heavy Duty and Standard models available
