SPOT WELDING EQUIPMENTS

HOW LIMIT SWITCH PLACE IN SPOT WELDING:-

Figure shows how limit switch place in spot welding machine.


DIODE

DIODE:-

      Diode is nothing but electronic switch. It conducts current only one direction called forward biased and it block current with another direction called reverse biased. Working like a ordinary switch or fan button. But it is one of the most important component of electronic instrument. Diode mainly used in Rectifier like Half, Full and Bridge rectifier, and also used for Protection circuit.


POWER DIODE


SPOT WELDING

SPOT WELDING MACHINE EQUIPMENTS:

      In a SPOT WELDING MACHINE one of the main component is limit switch.Limit switch generally    (1 NO + 1NC ) connection.Usually limit switch is normally open position and if we push wheel on the above box case it act as close switch.

limit switch-normally open

limit switch-normally close
