Hello...
In this video, I made a circuit that can adjust the output current for the machine I showed in my "Arc Boiling Machine" video, which attracted a lot of attention. I had set up a circuit during the construction of the machine. In fact, the circuit I made worked very stable and never malfunctioned. However, I guess it was a bit confusing because I did it with the method called "space assembly". Many viewers reported that they could not understand the wiring and assembly of the circuit in the machine. That's why I decided to make a new circuit that is accessible to everyone.
I had the PCB production done by JLCPCB company and I was very satisfied with the result. That's why I recommend it to you. You can download the circuit diagram and the necessary file for PCB production (GERBER) from the links below.
8 triacs can be connected to the circuit. As the number of connected triacs increases, the power of the circuit increases. For example, when using 4 8 Ampere triacs, a total of 32 Ampere current resistance is obtained. In this case, the power of the circuit is approximately 220x32=7000 Watt at 220V mains voltage. Although this value may seem very high, it is necessary to reduce the probability of failure for 2 microwave oven transformers. This power value can be considered as 110x32=3500 Watt in places with 110V mains voltage. Since I get a lot of questions about this, let me try to explain a little:
In places with a mains voltage of 110V, the welding machine will draw more current from the input in order to obtain the power of about 2000 Watts it needs. In this case, although 4 triacs have a total power of 3500 Watts, I recommend that those who use 110V voltage connect 6 triacs as there may be a risk. In this way, the probability of malfunction will be minimized.
The elements used in the circuit are materials that are chosen very affordable and can be found everywhere.
Input and output sockets have been selected as 4-pin to increase mechanical strength and current carrying capacity. Those who use 2 transformers and have 220V mains voltage like me can use the 2 pins in the middle. In places with 110V, since 2 times the current will be drawn, 4 pins should be considered as 2 pins, right and left, and if necessary, 2 wires should be connected. In this way, the current-carrying cable cross-section is increased.
You can download the PCB production file of the circuit below and upload it to the website of JLCBCB and have it produced.

I hope my video was helpful and you liked it.
