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.
Best one I've seen. Very neat install twisting the conductors for the potentiometers. I will be building this to repair my makita and milwaukee batterias! thanks for posting
Enjoyed the video, thank you for sharing all the info, yet something is confusing about the transformer that feeds the control board, ratings say (9v/1W), don't you think that's a bit low on Current??
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 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
At 3:44 you are adding a heat sink for the Triac , I'm guessing the controller board doesn't come with a sink , What would i specify when ordering , i don't see it on your list , also would a cooling fan in the enclosure help ? Thanks in advance for any help
Hi! Thanks for the comment. Yes, the controller board does not come with a heatsink, I just bolted a small one that I had on hand. A fan would definitely help if you are planning on using the welder for extended periods.
Thank you! Definitely go with the larger sq mm cable. I would go with 35sq and aim for 4 turns. Check my latest video to see how I upgraded the spot welder.
Hi, could you help me please? I made a spot welder with the same plate you made yours. Now it stopped working, that is, it does not fire. It has the two green LED's on and the red LED in the middle is blinking, but it doesn't trigger, could you help? thanks
Hi! Sorry for the late reply. I would double check starting with the connections, the trigger switch, then the 9V transformer output voltage, then the main transformer. Please check with caution.
one more detail about wiring need you to see that I am right or wrong. one wire from power plug (with on-off switch) connect to microwave transformer, and 9v transformer and the other wire connect to control board and 9v transformer and third wire connect to the ground. what is the wire spec. that you use for ?
Hallo great job U doing,I have question about it,I doing my spot welder and last night I damaged my control board because I connect 12v DC voltage along with fan ,do I have to use AC voltage to power control board as is described on the board itself? Please text me back,many thanks.
Great work, thank you for the video. I would like to build this one too, but the link to the case is not right anymore. Do you have another link or description to the case?
Hi! I got mine at a local electrical component supplier. You may check online for a project box. You can find the link for the wiring diagram in the description by clicking on the controller link.
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.
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.
Thank you! Please check my e-bike video where I have posted an in depth build tutorial including the upgrade for the spot welder. You will also find the schematic there. You can find the link for the wire stripper in the video description of this video.
My congratulations on the realization of your wonderful project, it's excellent, I'm interested in building one for myself. 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
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.
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?
I USED A110VAC MW TRANSFORMER AND USED 12 GUAGE MULTI STRAND WIRE FOR THE SECONDARY AND GOT 7 VOLTS OUT AND ABOUT 94 AMP CURRENT. BEFORE I TRY WILL THIS WORK ? AM I TRYING TO INCREASE VOLTAGE OR CURRENT ? IS MY SIZE WIRE GOING TO LAST ?
Very nice job, and very inspirational. Small tip about transformers: Input winding is not primary. Highest voltage winding is primary. So at 0:36 in the video, you removed primary winding. Not secondary :) Because transformers are intrisically bidirectional, wich side is input is arbitrary.
He is doing right. Primary winding is thick winding. Secondary winding is thin winding. Because microwave ovens uses high voltage from secondary winding.
I put some thermal paste in between but actually it turns out that the heatsink is not needed for the triac since it does not get warm at all even after extended use.
@@DonnyTerek Thanks for your reply. I see in some videos that the metal part of transistor , mosfet is conductive and should be insulated with a plastic sheet and plastic washer for the screw.

What a time waster. Too much video time showing how clever you are in doing the basics, screwing nuts and bolts, drilling holes soldering. Keep the actions relevant and technical and leave the basics to the builder. If the builder can not do the basics then perhaps he/she should not be doing the project. I am at this stage 9 minutes into a 12 minute video and really do not yet understand where you are going with it all, but my goodness I sure know how to drill a hole and screw up a nut and a bolt.
Hi! Thanks for the honest opinion. I'm actually not too happy of how I made this video myself now that I look at it. Definitely too much unneeded footage that should have been cut off. I will post some more in depth info on upgrading the same spot welder for better performance in my upcoming video.
@@DonnyTerek Hi Donny, hope I did not come across as too hash. I was trying to point out to you [as briefly as I could] how what was your potentially excellent project seemed to get bogged down in the wrong sort of details and trivia and seemed to lose direction to achieve the aim of the project. Nevertheless I really enjoyed the concept you were aiming for as well as your technical expertise. Keep up the good work.

Apart from the soldering.......
Hi so all i need to get is 110v or 220v?
Thats 3 turns needed on the transformer right? Because in the subtitles it says you wound 4 turns off camera.
Yes I did 4 turns. More turns result in higher amp output.

Hello Andrew, 220V.
how many amp 40a or 100a control board ? 120v or 220v to 9v transformer ? 120v or 220v microwave ? I am in usa.
