Portable Welding Machine || IGBT MOSFET Welding Machine|| Repairing circuit Diagram PART-1 AC /DC
Hi,
i am Anil vishwakarma Welcome to our KZfaq channel Science innovative brain.
About This Video:
Repairing circuit Diagram
Solid state welding machine
In this video web Lecture series we will learn about the MOSFET or IGBT based welding machine.
what type of component used
how the components are connected
circuit diagram & how the circuit will work
in this video we will first understand its ac dc converter part
means from input supply 230VAC to 325 Volt DC, how it convert ac to dc with soft start circuit.
1. Rating of capacitor 470 uf / 400 volt dc
2. 30 amp 24VDC relay
3.Bridge rectifier 60 amp to 100 amp
4.NTC NTC stands for "Negative Temperature Coefficient". NTC thermistors are resistors with a negative temperature coefficient
5. OR 100 OHM aprox 60 Watt resistor
6. Input output connector
7.Heatsink to cool Bridge Rectifier
8. 24 Volt DC Fan
Thankyou So Much
