- Just a quick update about my DIY spot welder. I've changed it slightly to accommodate the high current by using thicker cable and mounted the solenoid more rigidly to the battery terminal so there's not too many things flopping around.

![[Eng sub] DIY- How to make a home use simple spot welder with car battery](http://i.ytimg.com/vi/8bxBGA0L8NQ/mqdefault.jpg)
You should rig the button up to a foot pedal so you have both hands free. I have a spot welder and it comes with a foot pedal. It makes it easy. Also, build a jig to hold the batteries out of that plank of wood. Just drill 18650 sized holes in it so that they are in a line and close together and you have a holder to put your cells in while you weld them.
Why didn't I think of this before. When repairing a power tool battery pack, I was soldering the cells with copper wire. Rather messy because the terminals required cleaning and lots of flux and solder. And a lot of patience, too. Very good setup.
Many thanks for your video, I've just successfully made up a power bank from the Bangood kit. One word of advice to anyone else, practice first, I used an empty bean can and some nickle strip first, The first time it just blew a hole straight through. I am using a 75Amp hour battery and it only takes the quickest of presses on the moment switch. Neat, well done and thanks again
Hey, no problem, glad it helped. You're correct though... All it takes is the quickest press to do the weld.
In the US, standard ROMEX internal wiring should work well enough.
Picked up a motor cycle relay for $5.
Now need to find a simple 555 timer circuit to give me some standard 50/100/200ms timing pulses.
Most home stores have nice copper nails you can use as probes.
I would drill a couple of holes through a 4" piece of broom handle, run the wires through, attach to copper nails, and pull back so only probes stick out.
The most easy to diy spot welder around.Thanks man.
dang po thanks! No problem :)
Nonsense.
Hey man I made this and it works :) thanks! I fixed up a bunch of drill driver batteries with it, saved a lot of money!
Glad to help mate 👍🏼
Much better design! Cheers for this. I have a golf cart battery I'm gonna try this with. Cheers!
Spikey DaPikey I'm sure that'll work a treat.
Thanks for sharing your experience. I'm going to give this a try.
Please see my updated video for a better explanation: th-cam.com/video/o1NFbchHeM8/w-d-xo.html
Спасибо, камрад! По твоему видео собрал себе аналогичный "сварочник". Реле стартера от китайского мопеда (300 руб), провод ВВГНГ 1х6мм2 1м (50 руб), кнопка валялась давно с али аналогичная той, что на видео (т.е. у нее есть пара из пяти контактов, замыкающихся при полунажатой кнопке, т.е. пока кнопка не нажата или когда уже нажата полностью - контакты разомкнуты, замыкаются они только на короткий промежуток времени пока нажимаешь кнопку). Схема та же: один "электрод" от минуса аккума напрямую, второй электрод на от силового контакта реле стартера, другой силовой контакт реле стартера на плюс аккума, контакты, замыкающие реле: минус постоянно на аккум, плюс через кнопку от аккума к реле. Ставишь элемент, на него полоску, прижимаешь это дело "электродами", нажимаешь на кнопку. Если покраснели на миг электроды и нет искр - все хорошо, сварилось. Если полетели искры - плохой контакт, либо электроды не прижаты, либо пластинка к элементу.
Great Toutorial vid. Will make here down in Oz
Even a 7Ah SLA does the job. I use thick gauge flexible wire but sturdy copper nails at the end instead so I can really press down hard the wobbly strip that I just ripped off the one dead cell in a powertool pack. The solonoid coil eats about 4 Amps so a decent momentary switch u need...switches can weld together internally and so can solonoids, be warned. Fun to do!
Why people give it a thumbs down, i will never know 🤔
Very simple and work. Thanks for sharing
I'll be getting a battery tomorrow to try this! Thanks!
Chris Duke no problem. Good luck! :)
Probably the best it's gonna get as far as lead acid battery spot welders go. 200CCA is almost perfect for .15 mm thickness nickle strip. Solenoid switch is also very important for safety so you don't accidentally weld the probes together, creating a prolonged short. This can be dangerous as it will create heat in the battery's internal resistance which will eventually lead to an explosion. Shorting for a momentary push button press shouldn't be an issue though. Gj man it works great
Thanks! :)
@@darkkevind1978 I've just built a welder similar to this one. I put a 10A inline fuse to protect the circuit with the switch. I also put a quick disconnect terminal on the negative post of the battery. If anything goes wrong, the battery can be disconnected in a matter of seconds as no spanner is needed. To make it easier to use, I'm using a momentary foot-pedal switch instead of the handheld one. The battery I'm using is too big; the tabs on the 18650 can sometimes end up with holes if the switch is closed too long, so will replace with a 12Ah/200cca version.
Tryed this!
I found it unstable
Welding wise
(Try powering the solanoid with a separate battery) with low current around (10/11v)
If (12v solanoid )
Thanks for sharing
😉👌
....AND REALLY GREAT IDEA THE FOOT PEDAL...I JUST SAW IT IN A SITE THAT YOU HAVE POSTED THE WHOLE PROJECT....!!WELL DONE!!
GIANNIS LYMPEROPOYLOS I don't think that was me... What's the site link?
GIANNIS LYMPEROPOYLOS oh yes, that was me. I only drew the diagram though, I didn't actually make the pedal. I didn't need it to be honest.
This solenoid would work. www.ebay.co.uk/itm/152558511287

do you think this is better?it is rated 250a so 100 more ...so less time to make a descent welding...i also found this

THNX AGAIN..!!!
Thanks for sharing mate
nice upgrade
My car battery is too strong at 425 CCAs. Is there anything you can do to reduce cold cranking amps? Will changing the copper tips to something less conductive like a steel nail reduce the power?
Hmmm I'm not really sure... you need some kind of heavy duty resistor I'd guess. You could try iron or steel rods?
This is just amazing!!!
That's great! 😁
Well done.
Cool idea, thanks a big up.
Hello. is there a danger that the momentary button stuck and the current kept flowing?
Could you make clearly diagram how to connect solenoid relay and push button switch to positive terminal? Thanks
Hi for Aussie...
Nice job a small wood vice or some sort of holder for the battery and a foot control should make it a bit more manageable im going to give it a go thanks for brilliant idea
If your contact probe tips are further apart what happens to the weld? I am suprised they do not arc together and not create a weld.
Hi. I built my spot welder as per instructions. My first tries..why do the copper ends sometimes stick to the nick after the spot welding and I have to pulled them apart with a plier...any suggestions pls
i know you from esk8 builder, is this work really well for the pack so far?
random88ish absolutely! My pack is still going strong and I've had zero issues! This has saved me a lot of money!
random88ish
Excellent video! 👍
1. Can we use exactly same process and equipment/tools/settings for 32700 LiFePO4 batteries?
2. Also, how to weld the circuit wires to these nickels strips? (for connecting battery packs to the load etc.)
Isaac best to use capacitors and a battery source like lipo, lithium-ion or LiFePO if you're not using a lead acid battery.
Solder to the nickel where it's not directly over or touching a cell.
Thanks for the video it was interesting to find out! I made one exactly like this but using the copper nails you recommend I'm the latter video. It works but doesn't seem to penetrate the battery so the nickel strip doesn't get welded to the terminal of the cell. I am using the slightly thicker 0.2mm strip but from the same seller that you recommend. Did you have any issues like this? Thanks in advance.
James Harding I've tried with .2mm and mine seems very similar to the .15mm. sorry I'm not sure why yours isn't working 😕
darkkevind that's good to know that the 0.2 was the same. I'll charge the battery and try a different cell to see if that changes anything. Thanks for the quick reply! :-)
James Harding no probs. What wire are you using for the main cables? I've seen weak welds with too thin cables before...
darkkevind just as a temporary measure three main cables are the cables from twin and earth so quite thin. That might be the problem. The nickel gets hot and you get a good spark but doesn't penetrate.
James Harding yes, that will be the problem. You need at least 16mm²
Great project! Considering building this using a solid state relay -- any idea of roughly what sort of current draw you are producing during the welds? Cheers.
Yeah a solid state would work really well I'd imagine. You'd need one rated for the amount of amps your battery is rated for. The specification is basically how many amps you can draw from the battery, shorting it pulls the most amps it can do, depending on what you short it with of course (resistance).
My battery is rated for 200A but the solenoid I'm using, as it's mechanical it's only rated for 150A, but it's still going strong and working well!
Thanks, I might need to reconsider in that case -- the battery I was considering using is 1,000 CCA. Not sure I'd have much luck tracking down a 1,000A SSR... ;-)
images.truckworld.com.au/Ad/96743/1/535x401/1/0-acdelco-sn150-sealed-heavy-duty-battery-batteries
Ah yeah! That might be a bit much! :/
You only need a max of 800A for spot welding. Between 200-400A is the sweet spot.
Back to the battery recycle heap to chase up a smaller one looks like will be the go! :-)
Ok. Good stuff. One thing I want to ask. How do you charging your battery packs? And how you calculating time, current and voltage for it? Cheers.
Hi, I charge my packs with a 36v or 42v 2A charging brick connected to a BMS for the battery.
@@darkkevind1978 what type of BMS?
@@JnJShiffler Hey bro can i ask you ??
@@mouhssinekandoussi1399 sure, ask me what?
Good day mate. How's your weld on a 0.2 mm nickel strip?
Hola gracias por la información. Podrías decir que es la bobina que hay junto el borne?
Have you thought of using 1 capacitor and 1 resistor to controll time of the button push?
You could evan make the caps swappable for different timing for diff thickness and the would difinatly be more precision just push the button no more trying to flick it on /off as quick as you can
Hello guys.
How do you know what is the max current the battery can pull out?
Most of the batteries locally only mentioning the voltage and AH not max current output....
TechRise you need to try and find the CCA rating for the battery... Try getting in touch with the seller or manufacturer.
GREAT! Very good video ! Thanks
Dibe Bell no problem. Glad you enjoyed it :)
Hey is this a 4 pole solenoid
I have a Gb gsw22
SPST Momentary Contact Push-Button Switch (Black)
Part # GSW-22, will that work. If not where can I get a switch and solenoid. I went to the local electrical supply house and they did not have one.
Mike Hall check out the links in the description in my latest video about this, there's a few solenoids there, also that button sounds like it will be fine.
th-cam.com/video/b_kGgPVrcCI/w-d-xo.html
It was Very Good Equipment.
Brilliant idea ! Thanks for sharing. Made one myself but used a 40ah car battery, a bit too much power, blasting through sometimes while testing on two .18 nickel strips.
Do you think it would work better if I drain the battery down a bit first?
I have a 7.2 ah sealed type lead acid, any good for this you recon?
8plait anywhere from 200 - 500A is ideal for this. If you're going through your nickel, you may want to be a bit quicker with the solenoid on/off. I'm not sure that draining the battery would do much as it'll put out the same amount of current, just not the same voltage.
Thanks for clearing that up, think I will hunt for a smaller battery then. The difference between blasting through and welding with this one is too fast for me to get consistent. The small switch controlling my solanoid has a little arm that pokes out, maybe I can make a spring loaded device to flip it consistantly. Anyhoo, keep up the good work
Just looked at my battery again and it is 52ah, delivering 520A. I have ordered this timing board to hopefully controll my solanoid a bit better. www.ebay.co.uk/itm/NE555-DC-12V-DIGITAL-DELAY-TIMER-RELAY-WITH-MODULE-ADJUSTABLE-/162190347005?epid=545722282&hash=item25c34c4afd:g:rdsAAOSw9IpXytxJ
Fingers crossed it will work.
Unfortunately that won't work, it will only delay when the connection is made after you press your button, but then the connection is permanent until you switch off the circuit. You need a switch timer to switch on (via an external button) but then switch off by itself, within about 400 milliseconds.
This is what you want... www.ebay.co.uk/itm/12V-DC-Delay-Relay-Delay-Turn-on-Delay-Turn-off-Switch-Module-with-Timer/172821474475?_trkparms=aid%3D444000%26algo%3DSOI.DEFAULT%26ao%3D1%26asc%3D20170221122447%26meid%3D6eacbbd5a3ea4c36bc0548db22e371a4%26pid%3D100752%26rk%3D2%26rkt%3D3%26sd%3D172837186094&_trksid=p2047675.c100752.m1982
can i use stable power source like 12 volts converter power supply?
I see it's kinda blowing holes in the metal. Now they sell timers that you can use with this on ebay. I just made one with a 400w Metal halide ballast, transformer like on another video i saw where they used a microwave transformer. Except I didn't have a scrap microwave so I did it with what I have and I think it will work but I want to get the pulse control.
can i ask you maybe what im doing wrong? I bought the same solenoid relay, attached it the same way as you did with a momentary switch and if i push the button without touching i hear the click sound but when i touch the nickel strip it gets an weird sound and no spark, what am i doing wrong? Battery is an new Gel 12v 56AH
Misu Ka Probably that battery doesn't meet the proper CCA (Cold Cranking Amps). 😑
Hello! What kind of equipment is used for this video recording?
Yousun Samsung S7.
OK! Thanks!
Nice like it!
What material do you use to conect batteries.material? Thicknes?
It's pure nickel. I used 0.15mm and 0.2mm.
12v 12ah battery and what equipment used for spot welding plz replay me
Made this one but only wire I had was the ones you find in a house mains. What mm wire do you use for the tips. I get 2 welds and there hot to the touch
The tips are 2mm solid core copper (Twin & Earth). The wire you really need something like 16mm2
darkkevind1978 will have a look see if I have some cheers the main wires are about 16 they don't get hot just the tips but will have a good look about. The 2 x 2p work pretty good aswell
Ricky you may want to check eBay for 2 or 3mm copper rods. It's a good idea to file them to points where you make contact.
darkkevind1978 I'll do that thanks
Very good work m8, simple, cheap and effective. How many solderings can you make on a battery charge?
João Gaspar well, I got hold of it second hand almost fully charged from what I could tell, and I've made up an 8s4p li-ion battery pack with around 150 individual welds, plus initial experimenting welds and it's still almost fully charged.
Ultimately what you're doing is discharging the battery with little resistance but for a fraction of a second each time so it'd take quite a few thousand welds to discharge fully I'd imagine.
Is it possible to make this with the 12 volts 6 A transformer with 50 volts 3300 uf capacitor with the help of 5010 rectifier?
Thanks
Always good videos Need 12v 200w how can i achieve this goal using 18650 battery
Hi, what have you done in order to decrease amperage, because I have assembled the exact same desing and the amperage is so high that the weld strips simply melt and make a hole,
Hi, I simply used it for around 50 test welds and the power seemed to 'calm down'. Test weld to old batteries first.
@@darkkevind1978 I have tested to old batteries, but, every time the same result, high current, openning a hole on the nickel strip
Will this damage and eventually kill the 12v battery as you are in effect shorting it out?
It's possible. But to be honest, you're shorting it for 0.004 of a second each time so... 🤷
i am a fan!
i sent you an e-mail to improve the rod conections to the nickelstrip!
do share please
merci pour l'explication
Nice spot welder mate. What is the best way to remove a spot welded tab on a battery? Can you use the spot welder to remove a spot weld, like a reverse weld?
Jacob Coody no unfortunately not. The only way is to pull it apart :/
good work
ashar sumari thanks very much :)
Domyou think you need the solenoid? For a temporary fix just tap one of the heavy leads on the battery?
Much less control over the whole process then and much higher chance of prolonged shorting... could be more dangerous without the solenoid, I wouldn't recommend it.
darkkevind i will just have to wait to get a solenoid then.

Please help me bought one today but the relay does not have wire on it can it be used also
Awesome video dude! Currently building my first electric skateboard, U.K. Based myself and want to build my own battery pack will be having a go at this myself for sure, looking at building a 10s2p pack for my torque boards 6355 190kv motor, going for 18650 Samsung cells, do you have any idea on what bms I will need that the only bit I need to work out struggling to be honest hopefully u can help? thanks for sharing this awesome vid tho man
Adam Harriman hey that's great! Although, why not 3p or 4p? You'll have much more power at your fingertips. For your setup, this BMS is perfect: rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F263280228452
darkkevind hi David thank you so much for your reply and info regarding a bms, if I'm 100% honest I wasn't sure I could as not really that well informed on building battery packs and what's suitable for my motor vesc and bms, but if it means I get more range out of my board when it's finished it sounds like a plan! What pack size would you recommend for me and also will that bms u showed me be suitable? And one last question, where's best t find a charging solution for my pack? Thank you again for your reply and help I really appreciate it
I would go 10s4p and use this BMS: www.ebay.co.uk/itm/36V-37V-42V-10S-60A-Lithium-ion-Li-ion-Li-Po-LiPo-Polymer-Battery-BMS-PCB-System/221769582503?epid=1440597425&hash=item33a27f47a7:g:VV0AAOxywCJRa-m2
darkkevind awesome thanks for all your help man!
Can I use a battery charger instead of a battery? My charger has 2 amp, 40 amp, and 200 amp. Great video. Thanks
Panama Pepe no idea I'm afraid. Stick it on 200A and give it a try :)
It worked?
Panama Pepe prolly has a safety circuit. Maybe a fuse and/or short detection circuit. Battery chargers normally do some kind of battery safety check before doing anything else
how are you recharging the battery what type of charger do you use ?
I have a standard, small, car battery charger hooked up to the battery constantly, but only turned on after a session of welds to top the battery back up again.
Hi im asking... Can i use a deep cycle battery 200 amper ? For that project?
If it's 200cca then that's just about enough amps for a weld. Slightly higher CCA would be better.
What is the small straps
So nice video. I think you need a capacitor to avoid sparks!
telosfd thanks. th-cam.com/video/o1NFbchHeM8/w-d-xo.html
can you tell me what is the gauge cable diameter for the output of the solenoid..? i can search it based on the amps ..but what is the diameter of the two heavy cables that you are using?
GIANNIS LYMPEROPOYLOS 16mm2 but the thicker the better...
not the thicker the better cause you are playing with the limits of the welding tab area...!!i ended up taking this which i dont know even if it s the right product ...and the current through the short is 400a ...probably way too much...!!
www.ebay.co.uk/itm/112107789768
GIANNIS LYMPEROPOYLOS yes, the thicker guage wire you use (for the thick wire in my video) the better because it needs to handle a high current. Heck 10mm2 copper bar would be best. But the ends, the tips are 2mm copper from 2mm twin & earth cables.
The switch you linked to will work well.
thank you.....i saw the connector between the cables..but does that 2mm restrict the amount of transfered current ...its not like you grind the end of the thick wire to produce a fine tip...they are 3-4cm long.....last question...promise!!!!!!!!
GIANNIS LYMPEROPOYLOS it doesn't really 'restrict' it as such, but they do heat up because of it, but they cool down very quickly. It would be better to have much thicker copper rods and grind/file them to a fine point for contact on the nickel.
Can i use relay as solenoid?
How many batterys can you solder till the battery runs out of power ?
Arnold Horvat I think I do around 3 packs (40 cells each) before thinking I need a recharge. Normally it's at around 75% at that point...
Just use the 12V battery till its voltage under load is about 10.5V, then recharge the battery.
Brilliant
miodice3 thanks! :)
Hello, does your solenoid work like a relay?
Power Battery Channel hi, yes 👍
Thanks! Can you give me a link or write its model or name?
Power Battery Channel sorry I don't have it right now but I'm one of my other videos (check my channel) I list all components...
+darkkevind Thank you!
at 3:38 you show a beautiful close-up of the down-convert adapter from heavy guage wiring to the copper wires for the spot welding. Where might I buy this plastic 4 screw adapter?
Kevin Marck this is part of an electrical connector strip, also known as a choc block. You can get them on eBay: rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F252953965266
If you point the copper wires, you might get a better looking weld. Just a thought.
countryside yes you're right, that's what I did and I did.
countryside 54ee
Hello ,This is safe? ,did you get shock ,if you touch the Welder ?
Christian Kariso it's safe. Even if you touch the electrodes or the nickel you do not get a shock.
Hi! does it have to be a 500A solenoid relay for a 330A battery or does a cheap one also do the job? yours looks like a normal one! Thank you for your great videos!
Yeah mine is just a 150A relay from a moped... From 150A up will be fine 👍🏼
Can we use a relay instead of solenoid switch ??
Zana Hasan as long as it's rated for a few hundred amps, yes. The electro magnet in a solenoid is much more powerful than in most relays though so there may be some issue with disconnecting.... But it'll probably be fine... Try it ;)
My solenoid keeps getting welding abrasions which prevents the welder to continue working after the 1st weld. What can I do?
Try a different solenoid?
where i can get the solanoid ? or whats the name of it ?
It's a motorbike or ATV or moped starter relay. eBay or Amazon. Check the description of my other videos on this as I have links to the parts.
Hay mijo use thepisitive terminal as a screw for your ,stock up or use a solenoid for automobile and guess cables and hole to connect included
Can I use the solenoid relay 500A for battery 600A ?
Yes, for sure 👍🏻
ive seen your spot welder before was going make one but stuck with soldering for now.ive had lot of duff laptop batteries even new samsungs 25r packed up i bought 2nd hand guy said he bought new abroad but anyway as my soldering is crap perhaps will try your spot welder as have my dads old car battery have some scooter batterys too bought new off razors.electric scooters.we sold scooters as moved to a bungalow so had make room.
Blimey mate, almost right! Why didn't you post a schematic of the thing and let internet morons figure it out for themselves?
Unlike the prior INCORRECT video though, this is the correct wsy to do it, it allows you to stop current before relieving pressure between the tab and cell anode, thus aloowing HOT contact point to cool before they can separate and creating a "cold weld joint". The phrase used in electronic soldering is "cold solder joint", basically it's the same principle though.
If someone would just BUILD a $30 or $40 "NiMH tab welder kit" where all you need to do it hook it up and use it, I'd bet one of you guys would create a nice little cash business for yourself on Ebay or Amazon! Just build it NEATLY and PROFESSIONALLY because there is NONE on the market and I would buy one NOW if it existed.
Cheers
that is quite true... and china would produce those kits for 5$
Does it matter if you have the switch on the positive or negative side
No. Either's fine.
Where are the solenoid wires connected? Plus to Switch and battery and the other One?
The solenoid requires 12v to energise the coil (+ & -). So place the switch in line on either wire, it doesn't matter plus or minus...
I am confused on the solenoid wiring. My solenoid has 2 control terminals for control and two battery terminals. Help
You have a link to your solenoid? Two battery terminals will bridge the connection to one of the battery terminals, the control terminals will need to go one side permanently to either pos or neg, the other side should go to the opposite battery terminal but should have a momentary. normally open switch in lnline...
Thanks you
Wow I’d just assumed that was plumbing pipe at least haha
How many amps is the momentary switch rated for?
6A
hi its working now thxs
great job and video ... just switch to a foot switch and keep your hands free. :)
Thanks! You know what, it's actually a lot easier than I make it out to be in this video when I'm not filming. I don't think I'll get the kind of timing control you need for these welds with a foot pedal if I'm honest. It's really easy with the button in hand. If I incorporated a timer with the solenoid then yeah, a foot pedal would be much easier.
good
How many can you weld until having to charge de battety?
A couple of hundred I'd say... Although, I tried not to run it down and I have a small battery charger permanently connected (but not on), and when I've done a session, I'll flick the charger on for a bit too keep it topped up.
Is there a danger of explosion of the battery?
Only if you short it for a long period of time. For the 0.01 of a second you're shorting it for for these welds, no, there's no chance.
what did you use with positive pole?
6341026p sorry, I don't understand your question?
6341026p its caled solenoid.
I mean that the thing you used with Positive point what is that called?
It's a solenoid relay switch.
Thanks Dud
Would it work with a 6v battery?
LordWilsonVILLA yes, as long as it output at least 200A.
Cheers
Can I use lifepo4 battery pack instead of leadacid battery
It's not recommended. Lifepo don't like to be shorted.
What would happen without a solanoid? Can you show us

Great video. May I have the wiring diagram and the indication of the system components?

What charger do you use for the battery?
Ricky just a normal 12v battery charger
darkkevind1978 the battery I've got is a numax ytx14bs 12v 12ah
Ricky I'm not sure how many amps that can provide but you need at least 200A
