Hi everyone! In this video I decided to show you have I made a simple spot welder to save your 18650 batteries from overheating when soldering. It is a highly useful tool for a DIY'er that can be used in many different projects for creating rechargeable batteries and is super simple to make! A full parts and tools list below. You can find the wiring diagram in the 100A Controller page below. Hope you give this project a try✌️
Thanks for watching! See you in the next video!

12:02 just as a tip, the reason why the copper pins are sticking to the nickel strips, is because they are too pointy. If you round the ends of the copper pins, they won't stick anymore. I guess you figured this out already.

You can add an attachment like a diy "HOT STAPLER" for plastic repair commonly used now for car bumpers. I did, and it worked just the same as a $500 dollar unit. I just needed to add a switch to bypass the controller and it worked like a charm.

@DonnyTerek 3 жыл бұрын

That is an awesome idea to be honest. I guess you would only need to add some sort of power regulator to control the attachment temperature.

@user-sf9mh1ms4q 3 жыл бұрын

@@DonnyTerek I did not add any power regulator and worked just fine. I have a microswitch (in the welder) that I easily turn on and off to manually regulate the temp. Yes, it could be too hot but you can let go the switch even before you even touch the plastic if you want. so it is not a problem.

Is the controller just switching the primary? I'm considering a dual MOT welder with very short pw for welding copper strips up to .2mm to nickel plated steel (18650 cap) but obviously 100a at the probes would not be close. NM: Looking at the wiring diagram it's clear the primary is switched, so as long as the transformers do not exceed 100a - it will work. 1000w/120v= ~10amps each - allowing for losses

Following your indications, I noticed in the captions that the cable winding on the secondary should have four turns but you only show three turns. I also couldn't do four laps, just three laps. My question is, will there be any limitations on project performance? I would like to ask what are the ideal values on the display for better welder performance? greetings thanks

Here's the formula for turn windings Vout/Vin = N2/N1 For microwaves there's usually 1000 turns, N1 = 1000

@DonnyTerek 3 жыл бұрын

Thank you for the kind comment! I highly encourage you to check my latest video on the DIY spot welder that I have built if you haven't seen it yet. There I placed four turns of wire around the transformer. The performance will be much better with 4 turns. I got ideal values using 06 for pulse and 80 for current. You need to test yourself to find the best settings. Hope this helps.

@izzzzzz6 2 жыл бұрын

If you put too many turns the voltage will be too high and cause sparks, if too few and voltage will be too low and less power available. Did you get 3 or 4 in the end?

Why does everyone place both electrodes onto the nickel strip being welder? Would you not get better results by placing one electrode directly onto the cell, and the other onto the nickel strip? That way, all of the current passes through the spot being welded, and none of it short circuits from one electrode, across the nickel strip to the other electrode.

@DonnyTerek 3 жыл бұрын

I guess that would easily destroy or possibly result in an explosion of the cell since the current would flow through the electrolyte from the positive electrode to the negative, resulting in a dangerous short.
