- in this video {286} Inverter Welding Machine Repair Course / How To Repair #Inverter IGBT #Welding #Machine / Input Rectifier Circuit Explained & Troubleshooting. i discussed the circuit diagram and how to repair mma-200 or mma200 mma250, mma160 and troubleshoot inverter IGBT based welding maching. this china MMA-200T Inverter IGBT Welder Machine - Circuit Explained & Troubleshooting Part -1, is single phase 220 VAC operated. it have a bridge rectifier which rectifies the main ac voltage into dc voltage, which are connected to pair of dc capacitors through a relay contacts and in parallel 110 ohms ntc resistor. this nts protects from inrush current and upon receiving relay drive signal it switches the rectified voltage to capacitors so, the ntc is bypassed to get full current to drive igbt.
after watching this video you will learn:-
how to #repair #inverter #igbt #welding machine or welder
2. functional description of inverter igbt welder machine
3. how to troubleshoot arc welding machine
4. how to understand mma-200 circuit diagram and how it works

best so far on all of youtube! 🤗 I prefer east souheast and south asia people for this things!
Your channel is among the very best resources on general electronics anywhere. I think what I love most is your patient breakdown on how things work and the detailed explaination on such a wide variety of electronics. Your channel is one of the few places I can satisfy my appetite for learning and discivery. You are making me better with nealry every single video. It must be gratifying to know this is true for thousands of other people all over the world too. Blessings!
Nice video
El mejor video explicativo que haya podido ver acerca de soldadores. Muchas gracias
There are many wonderful videos about electronic in this channel. Thank you for sharing.
May Allah bless you. Aamiin.
Thanks and welcome
it is my pleasure. stay blessed
Very good video sir. As it was not expected surprised to have this series of videos on IGBT welder. We've got something new to learn. Thanks.
You're wonderful haseeb..!
Very good explained. Let me mention additional: Before testing DC relais with external power, one should take care if there is any fly back diode (not the case here). If so, polarity is important, otherwise diode could be damaged.
I have a different welder but the explanation helped me a lot. Thanks!
Super pomysl i Ekstra efekt👍
Very nice sharing ....✌️
Interesante video como todos en su canal .. gracias por compartir tus conocimientos saludos cali Colombia
My brother 👊 give you big 👍 keep safe
I'm waiting part 2 bhaijan, may Allah bless you by what u have done.
Sangat bermanfaat, salam support dan sukses selalu

Fine explanation but I think the purpose of the relay used here is that when power is switched on the capacitors should not be charged directly with 230V ac. Because if someone switches the machine on then off then on again. There could be a disaster and the capacitor could blast because it could hold voltage for some time. So the manufacturer placed a relay here to protect the capacitor. However, when welding will be started the relay will go on to provide the necessary current and will bypass the resistor.
Summary: The purpose of the relay is to protect big capacitors from blasting.
Thank you for your tutorials, may I know if you have tutorials in VFD's their principle is almost similar to the IGBT Inverter Welding?
Good
best regards
Nice🌺salam bhai
Maray sub bohat kam hu rahy ha..i think roz 15 frnd banty han.phir kam hu jaty han..kio nahe batata..ap help kar sakty hu k utube ke kio new police aie ha tuu..shid hamy na pata hu
Kio idea ha tuu bata dy..kiya log back.ly lyty han yah wajha ha..
Peace be upon you, Ustad. Is it possible to control the voltage coming out of the inverter welding machine? May God increase your knowledge
seandainya kita dekat, kita bisa mengerjakan proyek bersama
you are specialist electronic sir
well done
just on arc 200 they have two ntc thermistors one ptc thermistor one relay and 4 capacitors
can you explain and on this circuit or is the same ?
Thank you for your fully educative and versatile videos, that even a beginner can follow! Not many videos like these in youtube.
GOOD
best regards
How did u know it was dc caps not ac. Please make video on capacitors as well
Please make video on Japanese gas fan heater.
Yes mr haseeb thanks for the good service your offering us infact since I started watching your videos , l have got a great inmprovement in repairing work more especially on smps units.
Now I have got a challenge , theres a welding machine am trying to repair (arc 400, DC inverter arc welder mos), on no load voltage at the terminals and on the display is OK (78v dc) and current on the display varies very well when the current nob is turned.
But now on trying to weld, it sparks once at the electrode and voltage drops or disappears instantly but current remains displaying on the meter I don't know what could be the cause of this.
Thanks
please check the control card. might be its over current limit is misadjusted. you can try by adjusting trimpot on the PCB
I have tried but the problem has persisted and also the open circuit indicator is indicating open circuit I don't know what component could be causing this.
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 appreciated!
Hi, may you help me. Dose the 2 igbt the same ?
MashAllah
Lk 145 ❤❤👍👍😊
Hi bro actually I have tried to adjust the trimpot just the way you told me to do, but problem has persisted and also the machine is indicating open circuit at the open circuit indicator, I don't know what components could be causing this problem
Sir I wanted to know what it means by fly back , where do we need to use fly back diode and how does it work
I have analog mmeter, can you show me how to use resistance mode to test those bridge? Or resistance mode can't test it?
السلام عليكم استاد هل يمكن التحكم في الفولت الخارج من مكنة لحام الانفيرتر وزادك الله علما
SirJi, my model do not have relay and NTC. Pls suggest me some fuse or circuit breaker for input protection from high voltage and subsequent hi amp draw. My unit inrush current is 48 amps.
5:34 - Another way to distinguish the positive terminal of a bridge is to note the direction of both AC pins and the negative terminal pin are the same and the positive pin is turned 90 degrees.
Hello friend.
I need help for find a iC part no . Of current control board with SG3525 pwm ic . Thanks
sir i have a question regarding my welding machine capacitors the value are 450 volts 1500 microfarad but the test reading now are 1310 and 1315 microfarad may i know if they are still good . thank you
yes dear these are acceptable, most of time if we test this provide marginal readings, but if these selected using ESR meter then we can verify the ESR value.
Haseeb Bhai. Assalamualaikum.
Can I convert igbt welding machine into a 12v 500A rectifier for electroplating. If yes kindly guide me.
Jazakallah Khair
welding course online ഉണ്ടോ
lütfen videolarının hepsine imkan varsa türkçe altyazı ekle seni sürekli takip ediyorum. ingilizce olunca hepsini anlamıyorum. eğitimim yarım kalıyor. mümkünse eski videolarına da türkçe altyazı ekler misin. senden özellikle rica ediyorum.
if i showed you a video of my inverter welder could you help troubleshoot the problem ??
sure it will my pleasure
please send to my whatsapp 00962-79-1161084
@@HaseebElectronicsthank you so much.. your videos are amazing
i'm trying top figure out how to send it through whatsapp hahah but for now this is the link of the yt video
czcams.com/video/899W9WoHnyU/video.html power is on screen flickers then a light touch on the board and it starts
second video is with mig gun connected , someone suggested it is a,fault in the relays but they are hard to replace without special equipment i only have a soldering iron and a multimeter
