Project Description:
********************
In today’s episode, you will learn how to make this semi-automatic Spot Welding Machine using a 2nd hand microwave oven transformer. While making this spot welding machine I faced some issues which I fixed and I am 100% sure you will also face the same issues.
During my first test I could only see these sparks, it may or may not weld the nickel strip to the battery. I was pretty confused and I had no idea for how long I had to connect these electrodes. The welds were not good at all. So, at this point I decided to add some kind of control circuit to my Spot Welding machine.
I added a control circuit and then all the issues were just gone. My 2nd test was successful as I fixed all the issues, I designed my own Semi-automatic transformer control circuit, to control the ON/OFF and time duration. I am using these homemade copper electrodes and I am still happy with the results, for professional welds you can order some good quality electrodes. You can see this spot welding machine is doing great. The connections are quite clean.
In this video, I have also explained why not to use Steel or soldering iron bits as the spot welding electrodes. So, here is my spot welding machine and now I am going to explain the making and how to fix all the issues. Without any further delay, let’s get started!!!

The best thing about your channel is that you are honest. You don't fake things to get viewer.
Wow, this is the Best (easy and cheap) DIY Spot welder I have ever seen on RUclips. And it is safe. That on-screen circuit explanation is amazing, and the use of relays is great.

Your tutorial is the best i see about spot welder on youtube...i will do that...thanks...
I like the way you don't need a plug or fuse in the 230v supply to get the most current to flow.

Excellent job! I'm going to build one of these.
Love your explanations. I am going to try similar, thank you. Most videos, assume you understand and go to fast for you to learn from. But not yours. Interesting how some designs use motor cycle or car starter relays to time welds operating on the secondary coil . But you switch the primary. Through 12volt relay.and separate power supply, I like yours cos Old 12volt adaptors and old microwave ovens available from recycle places. Or horders already have. Plus by switching primary you are on for the weld only, saves power and things stay cool.
Awesome diy spot welder using a x'mer; time delay circuit using relays is very impressive. Thanks a lot !
you can check the arduino version of the same project, its result is like a factory made spot welder.
Thank you so much for such a detailed video. It helped me a lot.
The simulation was simply amazing. I fully understood the whole process. Thank you once again.
Спасибо мне понравилось
Useful idea thanks for sharing
Awesome idea, thank you.
11:41 brilliant ♥
This is the simplest solution I've found on RUclips for a timed relay circuit. Awesome. Can a potentiometer be used between the capacitor and relay number 2 for adjustable timing?
ya, you can use but its good to use a programmable controller board like arduino. I have already done this, check playlist.
PCB board sharing Thank you
Thank you for sharing with us this awesome idea.
how are you? after a long time.
Creative video, thanks for sharing :)
Amazing idea 🤩🤩
Very good 👍
thank you
Great !
Werner
Sir you are really awesome 😎
Thank you dear.
Very good
Awesome idea
Thanks a lot
Thanks
Nice build !
Thank you Philip
Спасибо мне очень понравилось, классное решение
Nice
Thanks dude
you are welcome.
I've thought about using mig welding tips for electrodes.
Great
Thank you.
Your input AC is 220-240vac, will this device work with only 110-120vac?
I hope so as I would like to build and use this device! Very nice video!

how many volts you have in the secondary winding
Cau I use normal transformer instead microwave oven transformer???
Hi, What is the Ampers of two relay 12v and type of relay? ,and what the watt off microwave transformer?
would be too strong capacitor 150 mf 63 volts thanks again
Thank you , please what's the details of relays ?
spdt relay, its a normal 12v and 10A relay.
@@ElectroniClinic whether the relay is connected to AC or DC current
1 mF = 1000 uF; 1 uF = 0.001 mF. In the video, he was talking about 50uf to 1000uf. 150mf too big?
why 150mf? i never said this. Use different value capacitors for different ON durations.
Its good to use a controller to select the time duration, i have explained this in my other video.
Tamil la solluga anna
sorry Anna, i cant speak tamil, but you can translate my article into tamil. link to the article is given in the description.
WRONG PARTS WAS USED ! THIS CIRCUIT WOULD NOT LAST LONG, PERHAPS A FEW THOUSANDS SPOT WELD, THEN THE RELAY (RL2) CONTACTS THAT CONTROL THE PRIMARY WELDING SHALL BE BURNT OR WELD TOGETHER.
Replace RL2 with a bigger relay, contact current rate at least 20A or higher. Parallel both contacts with 0.2uF 1000V capacitor to reduce arcing between contacts is even better to prolong the contact life.
can you answer my question on the video capacitor 100 mf and on the drawing 1000 mf
its 100uF
different value capacitors will give you different ON durations.
@@ElectroniClinic ok so 100 mf 50 volts is enough
@@mostamostar4251 yes, but you should watch my other video on the same spot welding machine in which i used arduino to control the ON time.
@@ElectroniClinic I will look and I followed your channel and would the capacitor 150 mf 63 volts be too strong, thank you again
on the capacitor it says 100 mf and on the drawing 1000 mf
