Sir your tutorial for repairing is the best,sir one inverter welding,oc light glow when Holder strike,whatever is the current value,,if Middle board connection is isolated then no oc light came,sir where from I can get the spare on line thanks God bless you.
Sir for feedback I want to share is that sir please share video how to take out control card and also driver board checking method for MOSFET machine and igbt also and how to find value and fault in control card
PART 1 mein power supply repair waqt ...power card nikala tha...thik usi tarike se control card nikkalna hei....halanki soldering rod min 125watt rehna
Snubber circuit is the culprit most commonly.... change the capacitor ...(even if it is okay) between collector & emmiter. If it is series with resistor check the resistor also. sometimes it is dry solder. try pull out the component by hand & check it may be loose inside. All the best...👍
आप जैसे लोग ही अधिकतम लोगो की पसंद होते हैं एक शिक्षक के रुप में ,चाहे विद्यार्थी अच्छा हो या बुरा ❤ sir which capacistor should be change if New IGBTs Burns after change ?
Very Soon ....keep watching ! Insulation liquid is the one used by moter winding people ...its available with those shops selling moter winding material.. 👍 All the Best...
@@saralelectronics642 sir, it'll really benefit viewers from outside India. I can barely understand hindi just enough to make sense out of what you say. Your blended teaching style of explaining schematics and practical repairs gives the perfect learning experience
Welding masine circuit me dc power high amper control circuit kese bantahe matlab dc. Power kaha input hoti he jise High ampiyer kese bankar aataa he ?
PART 9 dekhiye..... saath mein PART 7 aaur 8 bhi dekkhiye teen teen 475/400 volt k capacitor se high amplitude power mosfet se nikla hua pulse ....middle board k transformer k primary mein induse hota hei ....aaur step down karke rectify ...low voltage 70 volt karib DC banta hei....jo high amprerej detta hei....jaise load letta hei vesse output voltage kum hotta hei......wattage maintain rehta hei....
App dekhte rahe mere saab video.... Basic pe series karne soch raha hoon....iss se aapka knowledge aasan ho jayega...All the best...👍 . mera target students hei....aaur sabke k liye SARAL rahe...👍
It's a great videos describing the Circuitry in detail. Keep it up. Thanks.
Sir apka video s lisen iam 80%knowldge welding sicliyahum thank you sir
Sir ji aap ke video kaabile taarif hote hai shukriya sir ji
बहुत सुंदर है 👍👍
method of teaching is very good
बिगीनार स्टूडेंट को मदत होती है. थँक्यू सर ❤❤❤❤❤❤
Very nice sir
Very thanks sir, guide in Hindi language ❤👍👍👌👌
Request sir , make more video, helpful for students.
kemm cho...Chirag ?? God bless...👍
Ur teaching style is really remarkable
👍 Nice....thanks...enjoy
Method of teaching 👍👍👍👍. Very nice sirji
Thanks...!!
Sir apki describing methods bhoot badiya he 😍❤🔥.... Thank you so much sir❤
Thanks...!!
Sir,
Your video very helpful for me.
Very good explanation
Keep watching
VERY VERY NICE CLASS , MY HUMBLE THANKS SIR,,🙏
👍 Thanks...!
Very nice clas sir 🙏thanks &god blus you
Sir aapka samjhane ka tarika bahut achha hai. Sir 200amp ki machine me ye 30 amp ka relay kiu nahi jalata hai.
Excellent sir❤, sir please make video on TIG bottom card
Sir your tutorial for repairing is the best,sir one inverter welding,oc light glow when Holder strike,whatever is the current value,,if Middle board connection is isolated then no oc light came,sir where from I can get the spare on line thanks God bless you.
Thank you so much sir for sharing. If in English it’s very good for me
Outstanding explanation 🎉🎉🎉🎉
Good job 👍 sir next video I am weight
👍 keep watching & sharing
Very good sir

Very nice information
👍
I liked u r videos sir
👍
Sir good effort. Sir pl keep continue. Waiting for ur next video. Sir why IGBT burn immediately after replacement?

Thank you sir
excellent sir....
👍
धन्यवाद सर👍💐
Hum real circuit se circuit diagram kaise draw kar sakte hai?
Sir ji aap invartar par BHI video banao
Superb sir..
👌
Very good sir thinks
Welcome
Sir kya aap iski classes chalate hai mujhe reparing seknna hai...
Good job sir ji 💯
👍
Super sar ji you are great
👍
Please make and discuss Control card 30 pin removal video in practical way
yes ...will do so...
🙏
nice
👍
Thanks....sir ..
Great ...!! welcome
Thanks sir
👍
Sir 300 amp machine Banana hai kya kya samaan lagta hai sir
Good sir
👍
Subscribe kor diya
😊👍
Nice video sir g
Good night sir g
😊👍

Super Bhai

Top board working also sir for MOSFET and which material is used for insulation after soldering sir
Very Soon ....keep watching !
Insulation liquid is the one used by moter winding people ...its available with those shops selling moter winding material..
👍 All the Best...
Sir, single plate ki welding machine me igbt kharab hone ka kya karan hai
🙏🏻🙏🏻
Best mosfet welding machine in india,supan or polymak
Sir kam taiz nh ho RHA 8igbt me is py video bnao
samzha nahi aap kya kehna chahte hei...
welding machine pe saab cover karunga...keep watching 👍😊
3card mechine mAi 24,12,5 display and mosfet .middle board ok but oc comes plese give suggestions
voltages thik hei...OC k videos dyan se dekhiye....Top board mein koi ek side mosfet short hogga....check kijiye
Also how we can check transformers in MOSFET machine also sir
Normally they rarely fail...still you can check them ....if it is output transformer ....then they give OC problem ....will discuss on the subject..👍
Sir IGBT 60N60 (4 ) lagaya tha fir sahi ho gaya kuchh der bad short circuit ho ja raha hai .kya fault hai.
always check drive components driving the gate....for any fault...
Please make the video subtitled in English, so that everyone can benefit
you are from....??
English subtitle ....I have not tried....will see what can be done...till then keep watching 👍

Sir hame welding machine ke bare me sikhana hai please sir please
Sir koi koi machine ka display nehi hoti he but power led hoti he phir apki new green power led lagane ke bad bhi led on kiu nehi hoti he sir?
koi bhi led lagawo....check its voltages...connector .....galti se OC connector mein jack lagaya hogga
Sir please send me the MOSFET inverter welding machine circuit diagram i am ready to
bear the cost, please tell me the condition,thanks.
What is value of PTC
MZ32 101R .Having cold resistance of 100 ohm approx
Online class 1 no
sir kam sikha denga..mera Distik me kohi mistri nahi h sir aap ka no......
App dekhte rahe mere saab video....
Basic pe series karne soch raha hoon....iss se aapka knowledge aasan ho jayega...All the best...👍
Sir kaam sikha denge

Sir, could you please share your contact. I need some personal assistance on welding machine
Put your problems here ...will try sort out . PART 14 I have provided my no....whattsap only
Aap ka mob n.send kijiye sar ji
I avoid phone communication normally ....unless its something personal.. 😊👍 . I have no other reason....if needed will share later
Bhai aap ka number milega
Good explain sir
