[@rmjnm]

There's no videos like this on KZbin so far. Very informative and detailed video on electronic welding machine sir. Thank you very much.

[@HaseebElectronics]

most welcome you can also check my urdu channel (haseeb electronics Urdu) to watch my videos in Urdu / hindi language as well

[@scubasteve6058]

I’m a welding service technician in australia(very new to it 10months) this video was amazing. Very thorough and helpful to me. Thank you very much! This has helped me heaps as I don’t get much training at my job.

[@1977np]

Very excellent video nothing like this on YT. You made it very simple and straightforward. With a lot of respect. Your videos should be archived because these are master level tutorials and study cases. Highly recommended. Thank you very much.

[@joebbrorhie9946]

Wooh this is the best esplaination have ever gotten thanks man nice one and a big thumb up for you Pls am trying to fix one inverter welding machine with out no out put to spark up electrode, can you please Troy light on the possible causes that can cause output problem and how to fix it

[@HaseebElectronics]

best regards for your valuable appreciation in your case, first of all verify the dc voltage at main dc capacitor then check low voltage power supply for 5 volt 15 -15 volt then check the current setting pot then verify the IGBT drive, if no drive is there then check control card aslo check video number 286, 287, 288, 289, 291, 292 & 293 every video is to discuss each sub section and its components and their function and its test troubleshooting

[@desihiphop7653]

nice effort keep it up...

[@youtuberiocanto]

Super likeeeeeeeee 😉👍

[@dintotv9799]

Did u connected the bridge rectifier to direct ac current

[@HaseebElectronics]

first bridge rectifier is operated through soft starter circuit, then it is directly connected to line voltage, because it is high power circuit

[@hamzouz1229]

Thanks for the video.. you're the best ☺️☺️.. please what is the amperage of the rectifier?

[@sabasdumaguit3458]

thank you master....

great job sir

[@HaseebElectronics]

thanks a lot dear

[@modelmaker4784]

I received a single board. there was not any igbt. when i install 60T60 it doesn't do anything. when i install 60N60 its runs normally but igbt get hot within few seconds even bulb in series and without any load. do you have any idea what could be the season ? Thanks

[@tropangkalikot8925]

Very informative, you mention capacitor tester can you make a DIY capacitor tester or esr tester diagram

[@holawaleh]

I have this welding machine that doesn't weld. i noticed the IGBTs were gone. i have removed and replaced but it still not welding. on the multimeter at 200-ohms reading, the resistance is 20-ohm from gate to source even when mosfet are absent am i missing something

[@saukhilalnishad3370]

Can we use voltage drop method at high frequency to test non polar capacitors??

[@suatkaleli5075]

AS. please explain that why positive voltage to collector of the igbt and negative to the emitter? I mean we generally see the source connected to the emitter side of the transistors at the circuits. So it is supposed to be connected both positive and negative to the emitter side. but here this is different type connection.

[@lewismalamamwape5756]

Very educative videos sir. Now i have this question........ What could be the cause for the igbts always failling upon switching on? (reference is made to the welding machine ZX7-250 IGBT machine make)

Can you please explain how pulse forming network works..

[@HaseebElectronics]

sure a detailed series is upcoming very soon by this week

[@lastham4675]

جزاك الله خيرا

[@chinukist1]

Can we varry the out put voltage of welding machine?

[@HaseebElectronics]

yes we can. in welding machine the feedback is based on output current to convert it to voltage regulation, the feedback will be converted to voltage mode feedback

[@erwinganchoon1739]

Where do we adjust the output voltage of the inverter? the oscillator adjustment is only for the output current adjustment?

[@arunkumar-bh2dp]

thank you for explanation. we have one problem in our smps. we have multiple output smps in our machine. when we check output side of smps, it was showing 15v dc but battery charging voltage is not coming. there is no short circuit in put side . i checked voltage at capacitor 313v coming. but chopper transformer output side is no voltage. i checked opto coupler voltage at 1.070 v coming may be problem in chopper transformer or how to check chopper transformer

[@HaseebElectronics]

I am little bit confused from your question, because you said multiple output transformer, you have 15 volt, you have no output, you have 1.07 volt on optocoupler input. many thanks are mixed together 1. if you find 1.07 volt on optocoupler that is the biggest proof that the smps controller and high frequency transformer is working good please send a picture to my WhatsApp [phone]

[@arunkumar-bh2dp]

Ok i will send copy tomorrow

[@cameronlamoth2343]

Really good

[@HaseebElectronics]

it is my pleasure

[@AlejandroGonzalez-uh1fr]

Excelent video! but what about if I have arround 90V-100V at output of the welding machine? That means arise of capacitance and too low impedance or any other problem? Thank you

[@HaseebElectronics]

if you have excessive voltage that is due to pwm control card. when it's duty cycle will increase, then the output voltage will increase. it might be duw to the feedback network (operational amplifier connected with output current sense shunt resistor)

[@basheernajemaldeen3711]

Which electronic part is responsible for raising and lowering the electric current during arc welding?

[@mugenyirobert971]

Hi engineer, I have a problem of not knowing how to differentiate bjts, igbts and mosfets physically from one another

[@AltayOspan]

How to measure the voltage at the IGBT gate, should it be 1.6 V? Thanks in advance.

[@HaseebElectronics]
