Aapka welding machine reparing ka work hai ..or mai d.j. machine reparing karta hu par Aapke video dekhata hu. Aapke tecnic behtren hai.. mare pass bhi eak weld. Machine aaya hai . Aap ke sahyog se rep. Karta hu .. Thankyou..
Very nice video sir, please keep the good work going. Sir mere 200amp welding machine m jaise hi supply dete hai wo kuch seconds k baad mcb trip krri hai, kya aap bata sakte hai kya reason hai ?
Sir I am Mukesh Nayak sir I am ITI fitter mechanic work my age 53 year but I am working electrical only inverter welding machine repairing work sir your guideline all video my repairing work improve sir I'm happy & sir good inverter welding machine knowledge you are happy sir but my English not powerful I am driving message sir thank you god bless you
Series resistor is ntc not ptc. When switch on time ntc is high value capacitor is slowly charging.when heating ntc resistance comes down.the purpose of ntc is to reduce switch on surge current of capacitors. And protect rectifier also .
I'm currently repairing my total brand single board welder. It has blown 2 IGBTs. Till now i haven't found any causes. Any pointers? What normally causes inverter IGBTs to blow? Thank you for such a great tutorial. It has been helpful.
Hello, does the frequency change, through feedback, or is the pulse width the one that changes with a fixed frequency, to fix the output voltage, to the required voltage, thank you very much
Sir I received one igbt machine, the machine not working, because the power relay not closing,if I short N/O interlock by the help of a wire the machine start operation what will be the probable cause of failure, please explain.thanks.
Hallo apka samjhane ka tarika bahut hi sandar hai. Par mera ek daut hai smps kya hai ye kaise kaam karta bridge, rectifier kya hai,control card kya hai ho sake to 3 card wali machine ka video banye bhale hi 4 ghante ka ho ek ek chij bariki se batye mai aap ka abhari rahunga ...
Dekhte raho....saab cover karunga....aapka basics agar strong nahi hei...toh samazhne mein muskil hogi....isiliye basics series start karne ka soch raha hoon... 👍

Sir mera 200amp mc me output 70 -75vdc ata hai lekin welding nahi ho rahi.maine 30 pin control card ka dono ic new lagaya.4mosfet gate pe 20-5-20-5volt miltahai driver card ko ac 13 volt banti hai.kya check karne se out put me current milga.help me sir.
I finish replaced all 4- IGBT. After I powering my machine, power is good without a light of error indicator, but when I touch the torch to the ground the IGBT are blown again. Any recommendations to check parts is

Hello, does the frequency change, through feedback, or is the pulse width the one that changes with a fixed frequency, to fix the output voltage, to the required voltage, thank you very much
its the pulse width...(frequency is fixed) no change in frequency. pulse width does the output current rise or fall...as per current control settings
Sir app bahut acche se samjhate hai. Sir mujhe sekhna hai.. Mai aap se kaise jankari le sakta hu?
