Project Description:
********************
In today’s episode, you will learn how to make this semiautomatic 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 Semiautomatic 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!!!
