Micro controller Based Seam Welding Controllers: CSM


  • Compact user-friendly micro controller based circuitry.
  • Double initiation foot switch, FS1 operates the solenoid valve and FS2 controls welding operation.
  • Non-Volatile Memory (EEPROM) to store up to 15 weld schedules.
  • Easy to program with UP / DOWN and ENTER keys. A two-digit LED display indicates set values. Individual operations within a weld schedule indicated by LEDs.
  • Key lock Switch provided for SET & RUN mode. WELD / NO WELD switch provided on the front panel.
  • Timings settable in terms of HALF / FULL cycles of mains supply frequency to achieve better resolution. Precise time and energy control ensures consistent weld quality.
  • Relay contact output provided to actuate the Motor Drive of the welding machine.
