[@frederickvilamil2022]

Thanks for the great content! Is it possible for you to share the schematics of the welding machine? On the video series about welding machines the electric diagrams are a little bit different of what I have here on the welding machine I'm trying to repair and the one on this video seems to be exactly the same, but I was not able to find it on the internet. I'd be much thankful if you would share it. Thanks again for the great videos.

[@idontwantcorporateretaliat6301]

I have two identical AC/DC tig welders that have accurate current output for DC but inaccurate reading for AC (verified using current clamp). In AC, the inaccuracy is at low current setting (set 10; 40 A actual) levels and less inaccurate at high setting levels. Is it possible to adjust using trim potentiometers inside the machine for AC current only without affecting DC current accuracy?

Thanks Mr. Haseeb, this video got me thinking that is it possible to convert V&I mode SMPS into V mode SMPS?

[@HaseebElectronics]

exactly, it is doable

[@pakistani-vlogger.890]

Great work👍👍

[@abhijitdey5060]

Sir, this video is very helpful for me. Thanks for understanding this video. But I have a question. 🙄🙄 In UC3843 IC, if I connect the current sence pin to the ground then the IC will work (Only in Voltage Mode) and will adjust the output voltage only? 🤔🤔

[@HaseebElectronics]

yes you are right. at that time it will work in voltage mode

[@hassanhameed7967]

dear Mr. Haseeb firstly thanks for your explanation ,and I wonder if you can help me to convert welding machine(SG3525 control IC) to high current battery charger with constant voltage (14 v), thanks in advance for your reply

[@coeniebre]

I want to convert mosfet welder to Solar inverter

[@TheGovindtrm]

Sir, to use Uc3844 as a Led driver, should I connect VOLTAGE FEEDBACK pin to a fixed voltage or just left it open? Because I want to control current only..

[@HaseebElectronics]

voltage should me monitored either through the optocoupler or you may add divided voltage from aux voltage, so ic should maintain duty cycle using current sense with combination of voltage value in case voltage are uncontrolled , and there is some light load, in that case the ic can overshoot and make damage to the next circuit it is my suggestion

[@hichamtassi1753]

At 10:44 min of your video you mention the rebooting of the SMPS, i just acquired online a well built, second hand PSU from Germany 24v up to 6.28Amp. But at 5Amps it starts rebooting, where should i look at ? the sensing circuit ? thank you & Salam Aleikum.

[@russellmatheny8677]

I have a small Chinese welder. the actual working amperage does not match the digital meter. I found the 2 trim pots on the control board that control the max amperage and and the meter. My first question is how do I find by looking at the design of the board the maximum amperage the machine is designed for so I can set the maximum amperage. Secondly the digital meter is reading a non linear signal so scaling the voltage down to match the actual range of amperage is impossible....how do I overcome this. The board on the welder is a ZX7. Thanks your video's are great!

[@HaseebElectronics]

Good Morning. 2 Trim pots on control bard are maximum current limit, and welding current set welding current limit pot normally 20K Ohm. this trim-pot works with current setting potentiometer. welding current limit pot is used to calibrate the output current with selected range on panel by means of current setting first of all verify regulated 5 volt (mostly it is achieved from 7805 regulator) and ensure these voltage on display as well. there should no display when current setting potentiometer is set to 0 ampere. if it displays some reading set "display zeroing trim-pot" (normally it is 5K Ohm, most of the time on the display module) take a calibrated good multimeter to measure milli-volts across the shunt resistance, see the shunt reading (for example 200mV at 200A, OR there will a resistance value i.e 100 m Ohm). calculate the expected voltage drop on shunt resistance, and connect multimeter across the shunt with excellent test probes with minimum resistance (and note down the multimeter error) set current setting knob any required value. for example 100Amp. start welding measure the voltage drop across the shunt resistance to determine the current flow. check the reading on display, adjust by display calibration trim-pot adjust the Short circuit current limit to protect Over Current Light in this way you can scale / calibrate the current setting knob value, display value, and output current Maximum current or also called "Short Circuit Current Limit" this trim-pot is used to provide reference to control logic to set duty cycle

[@russellmatheny8677]

Thank you very much. I will try and let you know how it went.

[@manhardanmahedu3765]

Fantastic explanation as always,one more question arises in my mind that either voltage is dropped or current decreases at output due to load changes,in both cases switching IC will adjust it's duty cycle to maintain load current and voltage.Am I right?,if not please explain in detail.

[@Dynamic-bu8yq]

Hello Haseeb I hope everything is good , first let me thanks for your lesson and video , my question can I take adjustment voltage from welding machine I have Chinese welding machine with control card bk129-a3 it's dependent ka3525 , did you have any way to control at voltage, I need use my welding machine to charge my battery because I can't buy one , did you have any solutions? Thanks sir

[@temyraverdana6421]

Thanks for your video. Do you think possible convert a MMA welding machine in MMA, TIG and MIG?

[@HaseebElectronics]

best regards regarding conversion i didn't tried or studied feasibility so far. i will co-relate it and if possible i reply positively

[@royabraham3167]

Haii, is it possible to increase the current capacity of my SMPS,instead of purchase new one ?I have 24V/10A smps, but my load requirement is 24V/13A.

[@HaseebElectronics]

no it will damage the power supply actually any power supply must be operated at maximun less than 90% in your case it must be less than 9 ampere otherwise it will damage soon

[@royabraham3167]

Sir, i am asking is it possible to modify the existing smps range to my desired range

[@krisLight594]

can i use smps welding machine like power supply with high current,can i just add 100amp rectifier and 50.000uf capacitor on exit and use it for charging lead acid battery with regulated current?

[@donaldfeichtinger3529]

Awesome information!!! I’ve been watching a bunch of your videos and have a question about a machine I have been having problems with AC/DC inverter machine that has a power switching relay 5 pin that’s bad and I cannot locate one anywhere for it part number GP-24VDC-C54 do you know of a compatible replacement relay that is available currently

[@diadevrauuu9028]

[@anasory3225]

What the better welding machine mosfet or igbt one thanks

[@HaseebElectronics]

igbt design is more strong, if it is designed perfectly by some branded manufacturer copied designs produce problems time to time

[@tahirimran9881]

and also tell some jugar .if we have no igbt how can we use mosfet instid

[@wendekebede5499]

Thanks for your tutor. I want to download the schematic diagram please

[@goutammukerjee6229]

Sir, Namaskar, I have no words how shall convey my thanks to you for such a nice explanations, now my humble request to You to explain the control card of igbt welding machine, make 200a, the pcb having 1x uc 3846 ew, 2x 4688, 2x 393, 1x TLO 84 IC, IF possible please, thanks to You

[@HaseebElectronics]

best regards and lovely thanks for your valuable comment sure i will try my best to share it detail and we will discuss its faults and their solutions

[@goutammukerjee6229]

Namaskar Sir, I am very fortunate to receive your assurance, kindly provide the details of said control pcb, one more thing can I replace the control card with common IGBT 30 PIN Control pcb,if so kindly guide me the wiring diagram Please consider me for long asking, Salam Sir
