The value of these videos is priceless. Thank you so much for making such detailed tutorials! Next, can you make a video on how to make a Flux Capacitor for a Delorean? 😄
Very bad idea to solder directly onto Lithium batteries! The heat can melt/damage the insulating separator foil inside the cell, as well as boiling the electrolyte and causing venting from over-pressure. It's OK to solder (quickly) onto welded tabs already on the battery. However, the casing of the battery is a huge heatsink so you need to dwell a long time to get enough heat for solder to melt. This causes the damage to the cell. Much better to spot weld on bare (new) cells because the duration is far shorter, so less heat gets inside the battery cell.
What gauge of wire has been used at the secundaire part of the transformer, how much "VA" was the transformer? What voltage comes out at the secundaire side? Very nice for a hobbyist, many questions for profecional technician!
Very good work and perfectly explained. Just let me know the size of the cables used and if instead of the timer is possible to install just a trigger. Three seconds could be as well be counted mentally. No words were needed. Thank you. I did subscribe
You made a mistake in executing the welder machine. (I made the same mistake.) The red and black wire are very thin and reduce your current from the transformer . That's why the weld is weak. Double those wires and you'll get a strong weld . Yesterday I made a video demonstrating this. (this mistake.) I put a 6 mm wire in the transformer, and at the output I have over 600 A . But since I put 30 cm of 3 mm wire, the current dropped to 350 A. I will upload the demo clip next week .
there will be some loss in the high temp silicone wire, but its not much, the cable thats in the transformer is doubled up and thicker so it should be fine. if they used the red and black cable inside the transformer then you would be correct
very nice video and simple enjoyable work! with nice background music!!...Now I want to make one but Im unpleased that my mother threw the small kitchen she had to cook. and I cant get the coil. lol
Amazing well done that works perfect. I saw some coments asking for the size of electrodes, this is not a welding machine this is spot welding no needs electrodes
From what I understand a transformer is like a pressurize container that stores amps and shoots them out like our a pressurize water cannon shoots expect the transformer holds electricity am I right or wrong
You are very wrong. You might be thinking of a Capacitive Discharge system? Transformers (excepting flyback transformers) don't store anything. Transformers transform voltage and current in relation to the turns ratio. With a few turns on the secondary you can get low volts but a very large current.
Search the usual online markets. They are widely available, and there are only a small number of models I total. The ones with Blue LCD screen and 100A SCR are the best ones, as they offer dual-pulse with duration setting for both Pre (cleans the surfaces) and Main pulse.
It's a timer that can provide a minimum time of 0.1s when triggered. Compare to other simpler timers in the market, its biggest benefits is that if you keep the trigger signal longer than 0.1s, the working duration is still 0.1s No idea where you live, so I can't tell you where to buy it.
Bhai, the device you have made is really great, I have tried it at home and I have created the same for myself, but there is one information is missing in your blueprint of design for the connection of the timer circuit " a jumper need's to be set between GND & GNT_T of that module then the trigger mechanism will work else it won't work", please rectify in your Design properly and publish once again the blueprint.

Transformátor se dá získat z rozbité mikrovlnky. Ze skládky zadarmo. Odstraní se vinutí 2000 Volt a žhavicí vinutí pro magnetron (dráty uprostřed). Dále se vyrazí - svazek trafoplechů - viz video.

Většinou starší přístroje jsou lepší. Trafo málokdy bývá spálené.
buenas mi hermano como estas, mire tu video del soldador de puntos y me gusto, yo ya hice el soldador y trabaja muy bien pero me gustaría si es posible decirme el modelo de la tarjeta electrónica y donde comprarla porfa
some calculations would be nice. if you know your desired current, the mains voltage and the turns in the primary coil you can calculate the turns needed in the secondary coil, this is critical to know for this build, every transformer varies: for one an american microwave would need half the coils as a british one, however it may trip the breaker if the input current is too high, etc`, etc. video lacks any sort of explanation, i'd have that over some music.
by @1/2 the coils@ I meant in the secondary transformer coil to achieve the desired current, assuming all other variables are constant. Again, get a transformer equation off the internet, calculate it yourself, takes 10 mins to do.
First of all - ridiculously small wire gauge in the secondary winding, it should be at least 25 mm2, on the tip of the soldering pen can be reduced to 16 mm2, but no less
@hramota: This video is a fairy tale for adults, I say this because I built it for a test a long time ago, but unfortunately the result is not suitable, but I used a much thicker wire for the primary coil
Реле в плате управления на сколько Ампер? Если на 10…16 Ампер, то думаю его нужно усилить, заменив на более мощное изделие. Ибо токи в первичной обмотке хоть и кратковременно, но могут быть больше 16 Ампер.
Toroidal Transformer made from a microwave transformer? I don't know if it's enough for thicker gauge but most small ~20 watt guitar amps have a decent single 125VAC to 2-phase (12vx2vac), the core is similar in configuration but 1/8th the size.
How long can u use it? I make lithium batteries and I want to know if I can build batteries without getting too hot the wires or the copper plates. My current spot welder get very hot after welding 20 cells for example. I need to know i can weld without pause so I can try to build this model. Thanks.
quick question, the cable that you used in the secondary winding, I noticed toy used 2 core of that size cable, can you tell me what sort of current you were expecting to get out of that transformer and what voltage, and since you used that size cable why did you reduce it in the size that went to the welding tip
The timer board is more to turn mains power on n off through a low voltage actuated relay as not to have mains power in your hand when holding welding probe. low voltage relay controls the high voltage to primary of transformer..
I have a 3 phase 230 volt transformer output 48 volt 95 amp for a forklift charger Can I use only half of it (or 1/3 of it for 120 volt single phase) for making something like this? I also have microwave transformers but would like to experiment with this big thing. I mean I don't want to throw it away before trying something with it. Thank you.
The timer relay controls the PRIMARY of the transformer. Since it is probably a 1-1.5kW microwave, the primary current should only be 10-15A? (Depends on your mains voltage the transformer is designed for... For 220v-240V primary the current will be less..) You are switching the primary, not the high-current secondary. The load at the electrodes is resistive and so inductive surges should be minimal.
IT controls the primary of the transformer, but is not needed, use a 20 AMP 220v push button switch, mount it in the welding handle with 12 gage wire (good for 20 amps) and control welding time by hand, not critical
Is it safe to keep transformer opened, and not hiden in a box? I have bought almost everything i need to make mine welder, but i'm trying to figure out how to make a safe box for all those electric.
So, what is the circuit / schematic of your PCB ? Timer circuit ? What is its' function? If some DIY project cannot be replicated by viewers, this is just show off, not sharing.
For those who want to make this tutorial, let me tell I made it. He misses some important things and I really dont know how the hack is working for him when clearly the board is missing a connection for example. Anyway, I made it and the welding is not strong. He says 3 turns of cable but I recommend 4 if posible with 6mm cable. I used 6mm wire with 3 turns and the same transformer. The copper heads are from old battery spot welder. The welds now are not strong. I will try to change the cable with a 6mm and 4 turns and see if the welding gets stronger on 0.15mm niquel plates.
Plus tu fais de tours, plus la tension sera élevée et le courant moins important. La puissance est telle que Tension primaire * Courant primaire = Tension secondaire * Courant secondaire Donci si Tension secondaire augmente alors Courant secondaire diminue. Faire des tutos quand on n'y connaît pas grand chose est très dangereux pour ceux qui veulent reproduire l'exemple !!!
IT'S a secret, don't tell anybody, this transformers are.... Inside microwave ovens ! IT MAY BE A BROKEN, OR DISCARDED MICROWAVE OVEN, OR YOU CAN BUY... A NEW TRANSFORMER OR A NEW MICROWAVE OVEN AND REMOVE THE TRANSFORMER.... IT WORKS... BUT IN THIS CASE, YOU BETTER BUY A SPOT WELDER ALREADY MADE.... 😝😁😬
I don't understand one thing. That card is programmed at 0.5 seconds for example. If I keep the button pressed for longer than the set time, does the card disconnect anyway? Because I have another timed relay, but if you keep the button pressed the contact remains closed, even after the set time.
Your link to JLCPCB is a generic link to their website. Where is the gerber file for your control pcb or where can it be purchased online? I prefer the input voltage to be 120VAC from the mains @ 60 Hz. Where can I get a control module for that & how many amps would the mains needed for the spot welder to work from a 120VAC mains supply?

You made a mistake in executing the welder machine.
(I made the same mistake.)
The red and black wire are very thin and reduce your current from the transformer .
That's why the weld is weak.
Double those wires and you'll get a strong weld .
Yesterday I made a video demonstrating this. (this mistake.)
I put a 6 mm wire in the transformer, and at the output I have over 600 A .
But since I put 30 cm of 3 mm wire, the current dropped to 350 A.

Why bridging the ground ends?

This timer circuit is low ampere so how you control on it 50 ampere transformer?
The timer relay controls the PRIMARY of the transformer. Since it is probably a 1-1.5kW microwave, the primary current should only be 10-15A? (Depends on your mains voltage the transformer is designed for... For 220v-240V primary the current will be less..) You are switching the primary, not the high-current secondary. The load at the electrodes is resistive and so inductive surges should be minimal.
