AC to DC for Welding Machine Output Voltage (Under 10$)

#weldingmachine #ACtoDC #arcwelder
Hello...
In this video, as I promised to many of my viewers, I tried to show how to convert the output voltage from AC to DC in an affordable way for the Arc Welding Machine I made before. Of course, the process I did is not only valid for this machine. You can convert the output voltage of your welding machine with AC output to DC with this method. The materials I use are quite affordable. Total price under $10. For the rectification process, I used 5 bridge diodes of 50 Ampere KPBC5010. By connecting the bridge diodes in parallel, I have increased the current resistance to 250 Amps. You can use 5 bridge diodes in the same way for your 200 Amp welding machines. For higher current welders, the number of diodes needs to be increased. I connected a 4700 microfarad capacitor to the output. In this way, the AC output voltage from 40V has increased to 60 Volts. Of course this voltage will drop during welding, but for the first start of the arc it is better to have a higher voltage.
We can weld materials such as stainless steel by converting our output voltage to DC. In addition, the weld seam is smoother. Besides, you can use your welding machine as a TIG welding machine. Of course, there will be other materials needed for this as well. Maybe we can try that in the future.
I hope you enjoyed my video and my procedures were clear. If there are places that are not understood, you can ask by writing in the comment section of the video.

Hi!, I thank you all. Sharing your wisdom, for seeking knowledge to us all. Lots of humans can't afford wisdom. Too EXPENSIVE, EXSHAUSTING TO COMMUTE, but they had dreams to live in this unfair, abusive profiteering authorities that blocking progression.(greeders). I hope Education is FREE to COLLEGES to all COUNTRIES.

Very nice and tidy construction!
Many years ago my younger son built a TIG welding machine from my father's old Lincoln "tombstone" AC welder. He wanted to be able to weld very thin material, also, and we determined that a large inductor was necessary to stop the arc voltage from dropping to zero.
We found no information on the size of the inductor required, except an off-hand comment somewhere that in commercial machines the physical size of the inductor was about the same as the welding transformer.
Our scrap stores supplied the requisite transformer, which we re-wound as a choke., using the existing coil wire which we salvaged.
With added triac power control this new welder worked very well indeed.
Fitted with an arc starter this machine became a very fine TIG machine, too. Adding an arc starter has its own problems. If you wish to know about them, ask me here.

CONGRATULATIONS. THIS IS THE BEST STICK WELDER PROJECT I HAVE SEEN IN YOUTUBE. EXCELLENT DESIGN, MATERIALS, PARTS, CONSTRUCTION, ASSEMBLING, SHARP AND SAFE. NOTHING TO DO BETTER. I WILL BE WATCHING ALL YOUR PROJECTS.

[Historynerd]

Absolutely spectacular! I've watched a lot of welder builds and this one is fantastic! I'm building one now as I type this. Thank you. It's perfect.

[marioguzmanserrano]

Excelente los dos videos, la construcción de la maquin6de soldar y la conversión de AC a CC.. FELICITACIONES.

[victorenriquecarrilloorteg]

Excelente trabajo, lo hice con 6 puentes de diodo de 35 amp, en paralelo y hasta ahora la maquina me trabaja bien. Exitos

[Anonymatter]

A perfect way to arrange the bridges, very impressed.

Murat Ustam emeğine sağlık. Titiz bir çalışma ile son derece basit ve bir kaç yedek malzemeyle, ömürlük bi makine olmuş. Eski bi elektronikçi olarak, böyle ilginç ve güzel çalışmaları izlemesi keyif verici oluyor.

[josegregoriohernandez]

Saludos desde Venezuela, gracias por su exelente presentación.

Adding diode bridges in parallel is not recommended, because the diodebridge with the lowest voltage drop will take all the current and burn up, while the other bridges will follow one by one. It's better to choose 1 diode bridge with enough current rating, or use 4 separate diodes with enough current rating.
Also, when using DC for stick welding, your welding electrode must be connected to the positive terminal, and your alligatorclip to the negative terminal if you are welding thick material, when using very thin material (sheet / plate), your electrode must be connected to the negative.

thank you so much for sharing your ideas in making simple small welding machine. God bless

[КомилТуйчиев-гъ]

Главное работает если ремонт то мастер свой починит.👍👍👍

[CoachArt]

Thank you for sharing your Amazing DIY welding Machine video Murat Sef 💯❤️✔️ Seni seviyorum😊😊

[favourcornelius]

Good afternoon sir I'm so delighted to watch your video I see the kind of motivation they are given to us here the work is so beautiful the step-up Is very wonderful I've seen it and is working very perfect congratulation sir

[AyhanErkin]

Murat kardeşim, eline yüreğine sağlık. Ne kadar faydalı bilgi oldu benim için anlatamam. Sağol, varol.

[johnconrad]

The build is very good.
The largest microwave transformers are rated for abs maximum 1800VA x 2 = 3600VA/40V = 90 Amps. This is without considering losses. You may be able to push it to 100 Amps max. based upon duty cycle. However, the secondary wires in the transformer cannot take 100 Amps. They may be perhaps 60 to 80 amps. Unless you use a small duty cycle like the commercially available welders. whatever, it is still able to supply high enough current to weld. Now you must add the wire feed and the cable although you may be able to just do stick welding..

Now I know what to do with all these FWBRs I have stashed....Thanks bro!!!
