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..
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
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 ?
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.
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 .
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.
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
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 igbt ek machine hai jismai problem yeah hai road chalatay hai to o.c aa jati hai jaisay hi road tuch kartay hai oc light jal jati hai plz salution batao
Hello sir I am in srilanka .I have inveter welding machine low voltage [25v] but no welding. How can repair this machine.our country welding machine is from China. Please put one video.thank you sir.
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
I am new mechanic pcb working sir all video UP LODE inveterweldig machine guideline thank you sir I comment sir single cad & 3 card top bottom middle 30 lag pain control card diode IC with circuit diagram video upload for repairing work and checking output work thank you sir 🙏👍
Ek rod jalane k bad out put current and voltage bandh ho jata hay.fan and relay on rayta hay.main switch off kar k on karta hu fir vi chalu hota hay. What is the problem?
Sir,
You have lucidly and simple way you have explained all the problems in the circuit and how to find it.Thanks for such a good video.

Thanks sir for Valuable information
Very simple concept. Thank You
Good information
WOOOOOW well explained
Sr sar bahut achcha Bata rahe hain kya component
Very nicely explained n easy to understand.
Thanks and welcome
Zabardast ustaf
Thanks...!!
Bahot achhi video banayi he. Mere pas esab 200 amp inverter weld machine he, output nahi aa raha kaise thik Karen?
Display....??
AA Raha h
Sir ap me samjhaya Hai bohot badiya
Thanks....!! 👍
Sir plasma cutter ke upar bhi video banayen very good knowledge from ur video's we get
MIG/TIG mein banawunga....Plasma....abhi mere workshop pe nahi aay hei....dekhte hein....kab possible hogga....Thanks...!!

sir mere pass repear ke liye welding machine aai hai aur usme Siris me ok lekin darekt me nhi chaltaa hai
thank you so much sir...
Most welcome
Sir very useful video.
Good sir.
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
Thanks again.
Nice video sir. Thanks.
Sir u done good job pl share all repairing video thanks
