RKS-23 resistance welding regulator

RKS-23 resistance welding regulator is designed to control the welding process of spot, projection, and seam alternating current machines with three-phase or six-phase secondary current rectification with an increasing pressing force and provide, by operator command, the main welding parameters: welding time, voltage, current, electrode pressing force, forging. RKS-16sh version is provided for resistance seam welding machines, РКС-23T version is provided for resistance spot and projection welding machines.

Advantages of RKS-23 resistance welding regulator

  • Welding current stabilization in case of power supply voltage fluctuations
  • Thyristor contactor control and welding current control
  • Control of two electro-pneumatic valves of the electrode pressing drive and pressing force control
  • 7-inch display for setting the welding program parameters, displaying the current parameters and results of the last welding operation
  • Reproduction of welding cycles and storage of up to 20 welding programs in a non-volatile memory
  • Forging and squeezing mode
  • Reading of time delays in periods and half-periods of the supply voltage
  • Setting of welding parameters on the regulator front panel and digital indication of set parameters
  • Discrete reading and duration control of welding cycle positions
  • Setting of welding current within 25-100% of its full-phase value
  • Overload protection
  • Measurement of welding current in kA (completed with Rogowski coil current sensor)
