[@kennymanchester]

A nice touch offering up alternatives to solve problems. We need to be problem solvers and that includes not throwing away a useful piece of equipment just because one of the SMPS in a system is bad or unavailable components. Nice work around for measuring PWM too. Well done.

I am with a weld machin which turns on and turns off when i want to weld. O tested two IGBT and are ok. There aren't short in power circuit. But the wave form of IGBT gate aren't square and voltage in the module board is up and down in looping ( all eletrolytic caps and IC's). Same happens to fan connector. Why ? Is it PWM the issue ?

Please can I convert this welding machine to 400vdc power supply by modify it's transformer

[@unalakdogan9416]

Will installing an external smps circuit to replace the broken smps circuit cause any safety risk? Because when we install an external smps circuit, the relay driven by 24V will be instantly active, the NTC will be deactivated before the large capacitors are full.

[@HaseebElectronics]

This trick works nice And safety remains in limits because both bulk capacitors take approximately similar charging time

[@MusaMusa-sw4ek]

This is what I call power jumping, some times if I fail to get the ic ,I use a 24v external Chinese smps in Uganda it is difficult to get spare parts,so as a technician I use a 24v smps. Thanks for your work.

[@hugoegon8148]

I doubt that 68kOhm is correct. If so, Vcc of IC would be 55 Volt that would be too much for capacitor and IC as well. Looks more like 15 kOhm. Nice trick with external power injection on capacitor to check function of low voltage aera. Thank you. 👍

salam geet video, everything is clear especially with schematics, for me you are the master of electronics, i get the problem when found a circuit diagram. i have ARC welding machine 200A witch contain a TL084CN, my problem the output frequency is under the normal 29 khz and i don't know the condition of problem, can you advise me to solution

[@jafinch78]

Wow, great series of videos! Thanks for sharing man! Much appreciated. Any videos on offset high power circuits say for instance like taking the square wave like from a modified sine wave inverter (though for use in welding I'd like to know eventually so to construct) and offsetting so able to set different ratios of DCEP or DCEN for TIG welding aluminum best. Seems like need another half bridge so a full H-bridge to be able to design & construct. Then can make the alternating current square wave that somehow can be adjusted to offset where I guess just having a power control of some sort like another PWM or switching circuit for each voltage range side (DCEP and DCEN ) to change the power averaged on each side H-bridge switching event.

[@jafinch78]

On another and somewhat similar note, I'd like to learn how to use the Prius Gen3 inverter h-bridge for generic rectified inputs for optional 120, 208-240 and 460-480 pure sine wave outputs since seems like is feasible with the properly designed controller. I was also wondering what would be the best way to design a circuit for options to output as a welder power supply besides feedback for CV or CC and frequency control, in particular a high power offset circuit so for use in aluminum welding, i.e. an offset square wave so can select a range of DCEP or DCEN ratios. So that is why this is somewhat related since the control board design would be similar for the welding controls. Thanks again sir! Excellent channel! Glad I found.

Can you please advice whether to change or bypass when the step down low voltage transformer (24V) has been burnt? Thanks

@@HaseebElectronicsThanks for quick response. So it would not be possible to process the output transformer that would give a higher voltage with less current? HV start and solenoid valve activation would easily be added to an existing source.Greetings from Croatia

[@joeturner3970]

Hi, I have a similar circuit from my welder. I believe it acts more like a current source, than a voltage source. If I want to convert this to a a 48 PSU, can I just... 1. Reduce # of windings on output transformer (it is middle tapped, so I'd reduce each side).. 2. Add a large electrolytic capacitor to the output? Ta.
