RS 400E

Energy Efficient Thyristorised Welding Rectifier RS400E

construction is rugged and based on proven design to be an obvious choice for project site jobs for regular and pipe fabrication needs.

The new arc force control facility ensures good control over root and side wall fusion especially for pipe welding applications. Besides the special reactor design ensures smooth rippled beads and very low spatter.



  • Excellent reliability with high performance, suitable for shop or on-site use, even with long leads and cellulosic electrodes
  • Immunity from AC input fluctuation of ±10% with built-in overload and thermal cut-out protections
  • Arc force control for pipe welding applications
  • Low power consumption
  • Ideal for TIG welding with suitable accessories
  • Remote control facility
  • Rugged construction with heavy duty under carriage and rubber wheel
  • Rubberised wheel for easy mobility
  • Class-H insulation for coil windings ensures long life for use at even the most hazardous and demanding conditions
