Use this battery to power you Kweld - ebay.to/2lAJyLh
This is by far the best 18650 spotwelder I've used to date, fast doesn't get too hot and consistent welds. The end result would have looked much cleaner with new cells rather than recycled - but recycled cells work for me.

So how are you doing your bus bar style connections with the spot welding?
How does the battery work without bms?
@@7lovefreedom Anybattery will work with out bms.... it's just safer with it! For its given application it will be charged with hobby charge to keep cells balanced. For it to go to low we would need to be using it for a few days
I own one, and have been very pleased with it's performance. I'm very thankful that this very skilled electrical engineer created this and made it available. Having it has opened up a ton of possibility for me. I hope my comment supports someone's confidence making the purchase!
I can't wait for his scooter ~!
I also have the k weld and very pleased to own one too.
it just did, gonna order it right now.
On the output it is best to have as little resistance as possible. I therefore tinned the output leads connection to the board and as the bus bar connections. In addition I soldered the copper cables into the copper electrodes which I hold in position before pushing the foot switch. I get much more flash and have never needed to move the power from the lowest setting to spot weld successfully. This was after advice from my electronics guru friend, who said that to get the amps up as much as possible the resistance must be as small as possible and demonstrated the maths to me using v=ir.
Dude, your setup is insane, RESPECT!!
It's taken a long time but i'm pleased with the results that's for sure
Love your vids, great info, great techniques!
Thank-You
I have this spot welder. Love it. Perfect welds every time.
Cept when i do it lol had it set to 10j rather than a lot more :)
When can i BUY?
Thank you so much TH-cam for recommending me an amazing youtuber
I don't think so, just an average guy kicking back and having fun
I bought one of these too after trying like 3 different Chinese spot welders. Nothing else compares totally worth every penny. But you should really try the auto mode on that thing! I got a foot pedal for it but never hooked it up. The auto mode seriously save so much time and make the task of spot welding large packs a breeze!
Auto mode is next level fast love it!
Looks good. Thanks!
Thank-You
This spotwelder is probably the best available for 18650 cells! I followed the development on YT - brilliant idea! Anyway your welds look very weak to me - you should at least use 80 - 100 Joules! And i would do 4 weld spots on each cell instead of just 2 :-) Instead of the annoying music you should better just talk and share your experience :-)
I'm so sick of talking and editing my incorrect pronunciation & info I love this style better. That said next one I went a toattly different direction and did an under 2 min script then voice over first - then got the footage - see how that turns out.
can you give me a link to video where is that spot welder made?
@@Damjanhd email link in the description to the US seller of the unit Damjanhd
Who made the damn thing? Looks nice! How much would Mainbord cost + fuse cost? The rest can be diy'ed. And Bluetooth to app could be a cost saver instead of rotory encountered and a screen.
I would like to see a power supply with great efficiency for atx pc and server running on 48V pv system
100 joules? Youre joking right? its 10000 W if you use 10ms. 20 joules is enough for 0.1 - 0.12 pure nickel.
You do beautiful work. A true craftsman. Super efficient and methodical.
8:51 Even the wear notch in the workbench serves a purpose :)
Thank you very much!
Flip tge fuze over so it canbe replaced by just losening the bolts?
Amazing job!
Thank-You
I bet crushing that underside grid was satisfying!!!
I didn't do both sides :) if that is what you were referring too
great video bud well put together now I have a question I want to make a new battery for my e-bike do I need a spot welder or could I solder them together
I soldered mine without any drama...couldn't justify buying a welder ;)
I've soldered 1000's of mine - without issue - I still now feel that spotwelding is much better for many reasons
amazing work
Thank-You Sir
Hi, nice video I prefer to use the boss aulakiria spot welder over the k weld. As it gets the job done in a breeze. Thank you.
Clearly you've never used this one then :)
Great video Pete. ;)
Thanks for all the help and replying to dumb newbie questions & for all the shink - OOoh yeh!!!
wow amazing project, i like it
Thank you Electronic Make
Hey Mate, Im ready! ish... would you recon soldering the busbar to the nickle strip prior to kwelding the strip then soldering to avoid heat on the cells?
Pete, did you measure how many amps was taking from the 4s battery? I'm wondering what is the minimal parallell cell amount for this to work....is 80p enought or too little? Thanks
frnandu 80p is plenty if you have like 5A max draw cells at minimum
@@maxb6859 I know the cells deliver more amps at short bursts, but if we assume they did 5 amps each, with 80 cells in parallel, they would deliver 400 amps. That's under the recommended amps.
Make Spotwelder need spotwelder :)
Spotwelder good...
I've been looking into making one of these, what kind of energy makes a good spot weld? I'm trying to size my capacitor bank and when I use the formula for specific heat, melting nickel requires like 4000j! I scaled it down fora small pulse but still don't know. What is your pulse time and capacitance bank?
4kj !? i think its only like 50j - 150j for those nickle strips.
Didn't quite catch - where did the STL for electrode housing come from?
Glad i could help :)
Jointing compound between the bus bars and PCB not needed?
Nice vid Pete how do you compare the kweld to rowans sunkko that you were borrowing?
Don't mind me just read the video description lol
Awesome! Btw the cell holder doesn't need supports to print successfully.
Did you notice the cell holders plastic expand slightly while it was warm after all those welds?
Didn't notice have another test to do tomorrow, I'll take a look then
Great tuto! Can you give the link to buy the spot welder kit? Thanks
email is in the description buddy..
I wanted to know where you got the STL file for the electrode holder??? I just put my kweld together
in description buddy
Great video!. Do you think is only for níquel metal?. Could I weld thin zinc galvanized metal?. Thanks.
I don't know never tried sorry only nickey but it can do up to 0,3mm thick
where did you find that and what is it called and did you give that one spot welder away that you was talkin about
this one is a kWeld unit - facebook.com/groups/KWeldNorthAmerica/ not giving it away but it's available to my local community to borrow
nice project.
how is the spotwelder being powered? in your vid its powered from a battery pack, are there other ways, or is that the way to go?
also isnt the fuse installed in backwards? i mean they dont have polarity, but shouldnt it be installed so it can swing out when loosening the nuts? in your case if you ever have to change the fuse, you would have to unscrew them completely?
It's being powered by the recycled 18650's on the wall just taped 4S off the 14S battery, it'll run on little lipo packs with high VERY high amp draw ability or a car battery as well.
@@HBPowerwall would it be possible to craft a supercap-bank too? i mean you could put 5 supercaps in series and you have ~14v when they are charged, with a cheap low current powersupply that does CCCV, and can deliver the power in a more compact manner?
@@HBPowerwall What size of Battery would be recommended? And how big?
where did you get the files for the electrode holder?
Yes please share this with us!
I would like the STL of the electrode holder please.👍

Try this 👍
Die Punkte sehen nicht sauber verschweißt aus. Zu wenig Energie?
Way too little - needed the video finished and didn't have the correct battery setup to power it.. In a few hours I'll do a stress test of it and fix the weld strength
8:03 make my diy welder tip like this
Top!
Very good!
Thank-You sir
I would think that you would want to hold the electrodes as vertical as possible in order to reduce the area of tip contact. Since all the current passes through the tips, temperature is not just a function of energy delivered but energy per area of contact. Tilting the electrodes contacts the tapered sides of the points and increases the contact area, distributing the current over a larger area, and reducing the temperature. When you angle the electrodes you can see this in the shape of the dents created.
It might be possible to estimate the area in contact by measuring the resistance between the tips prior to the weld, and adjusting the delivered energy appropriately, but this would be difficult to do with accuracy I would imagine. In summary, I think you would get better and more consistent welds if you hold the electrodes more vertically.
setting up this unit is key - something i didn't do while filming
Hope to get one within a year or so. (Need to save up for it)
Hi Pete. I bought one of those units myself a couple of month ago and it works like a charm since day one. The features it has are just awesome. Like your electrode housing - is this your own design, or did you get it from somewhere? If it´s yours, would you mind uploading the STL´s to thingiverse...?
It's available from facebook.com/groups/KWeldNorthAmerica/
@@HBPowerwall Hi, I hate Facebook. there is another site I could have this STL file?
Hello HBPowerwall,
Do you have an .STL file for the KWeld triangle handle? Or maybe know were to get one? Thanks for the nice video!
John
I did think it was In the description? Should be on that 3d printing site i can't remember the name of now i thinks lol
Nice work! I wanna diy a 18650/21700 battery pack，could you please tell me which spot welder works well and where to buy one？Thanks!
could you share or give the link to the Kathode holder? I have been looking for those files but cannot find them... Rather strange, or I am looking them up with a wrong name.
Hi. Did you manage to find schematics for that electrode holder? I have been searching the internet for 2 days and I was unable to find them.....
@@miroslavzeleznik1986 Hi, yeah with a bit of luck I found this forum post with a download link.
secondlifestorage.com/t-Downloads-3D-Print-KWeld-Electrode-Housing-Holder
And I have printed out the file in ABS and they work great :)
Hi, please could you give a Link for the Compression plate V1.0, thanks a lot for the Video!
In the description bud - it's on the second life storage forum
Thank you so much
Almost any time
Those welds at the end of the video dont look like they will stay for long
nar they sucked, not enough amps covered that in the next video
Boy. 20 years ago, it was a lot harder. Good show...
Thanks
Hey man, what a great vid! Did you design the electrode tip yourself? Either way, do you perhaps have a link to the model ;)
Thats the kit how i received it
@@HBPowerwall I emailed keenlab and they sent it to me :)
btw , thanx for the effort showing whats out there but your link doesn't go to anywhere showing a price or way to buy one
I made a spot welder with a microwave transformer. it works like a charm
I bet it does, but I would rather spend that time making videos than doing stuff over i don't understand :P
Do you know what those connector tips are called that you crimped onto the wires that went into the terminal block?

HBPowerwall thx for the reply. I was actually talking about the terminal ends. I found the name. Wire Ferrule Terminals. Here’s an Amazon link if anyone else has the question. I wish I had known about those years ago. www.amazon.com/dp/B07H29ZTPX/ref=cm_sw_r_cp_api_i_IR5FEb2Y8AQGR
hi, where do you get those batteries ? from recycled battery packs or what? if so, can you tell me where you get them and for how mutch ? :D thank you
I get them from all over - if a company has a IT department they are fair game.. Challenge these days is get them before the recyclers do so you pay less & they aren't picked over for the good cells.
@@HBPowerwall ok thank's :)
any time
Could you share which power supply do you use and do you have a link to those 3D printed parts?

good work
Thank-You
Protip: Preheat the plug before soldering in an oven. This makes the solder stick better.
great pro tip..
I am about to order a couple of these as well. Just emailed the seller a couple days ago.
Nice, i'm very happy with the unit so far
is there a link where one can buy that super spot welder?
facebook.com/groups/KWeldNorthAmerica/
hmm make an adaption to the contact holder and get a "dobot" to run in palletize mode for spot welding a whole pack mmm just a thought
would run out of cells instantly - but i like the train of thought - even putting two cables and tips together do the four welds at once per cell but getting that level and even contact between all four would be difficult i guess
@@HBPowerwall not with the right spring tension on each tip
awesome video you convinced me to snag one up I also love the tunes!
Thanks for the feedback -
you won't be sorry it's a great spotwelder
LOTS OF AMPS!
What was that tool you used just after stripping the wires that made the magical helical pattern appear in the exposed ends?
Love your photography and editing. (Also made me remember that I have a volume control, hahaha.)
what time stamp bud ?
@@HBPowerwall4:30
OMG.. Rather than this, It will be great if you share your workshop tour as a video... :)
There are many tours - unfortunately can't find them on my mobile to link them sorry.
Hello. I made a spot welder machine with microwave oven transformer. It has timer module. but burns occur on the nickel strip. Do you have any idea about this?
This is why i love the KWELD, control, consistancey and accuracy - DIY is great but dam this product keeps working I would hazzard to guess at about 50 to 75 thousand welds so far.
happy days havin a pizza watchin my buddy make a kweld video priceless
I think i need pizza after this one lol
@@HBPowerwall you did a pretty good job on it IMO catchy tune too
did you do the ave thing of going click when tightening all of those bolts up ie human tension wrench
@@dtec30 had one back in the day, now it's she'll be right - seems good!
@@HBPowerwall you had a dobot ok how much was is to buy they seem unusually coi about the price thesedays

4:00 a painful moment for every electrician…
What do you use as a power source?
It's shown in the video at 9:43 and I can already say: you probably don't have it ;) I'm still waiting on my XT90 connector to be able to use my Kweld... can't wait!
Hi, just bought the kweld week ago,
I did some nickel solder! Then I took a break and when I reconnected I have the overcurrent message that appears, do you know how I can solve this problem?
Thanks
Check the manual, I hear so many stories of people using the 'good enough' way of building..
Awesome spot welder. I have it and would not own anything else!
I would say I love it but it's always out on loan and haven't seen it much since this video was shot
HBPowerwall that is what happens when you have a great product. :-). Awesome video by the way.
What is the magical tool at 4:30??
That's a ferrule crimper.
@@heyallenify there is also a male circumsizer ......!
Is it possible to use 4S Lipo's instead of 3S as power supply?
As long at it can handle the inrush of 1000 odd amps
I don’t know if you did it or not, but there’s a setting were you increase the Joules it gives out depending on the thickness of the nickel strips it gives you a better weld, but maybe you did already.
Just wanted you to know.
Could you share the recommended amount of joules in function of the nickel thickness?
How hard do you have to press? I’m new to this
I would describe it as firm... other wise sparkie sparkie lol
Good project ! Can it weld 0.15mm nickel ? Thanks
Stomps it .....I think i have some .2 and it stick that easy!
It can weld 0.3mm as well, but you need a cut in the middle of a strip
You should not have a steel washer between the cable connector and the fuse-ends. The cable tips should be pressed directly against the fuse.
Makes sence... ty
@@HBPowerwall Forgot to mention, it's a great video, and you are doing wonderful work.
I'd like to see this in a handheld format. Two points which the has a button in the hand held would make it faster. You simply put them down side by side the push a button with index finger rather the foot
It's even better than i did in this video - take the probes out of the holder put the unit into auto mode, touch one probe to battery - touch second and ZAP - it's so stupid fast in auto mode - the unit continues to amaze me
@@HBPowerwall great to know:)

Where do you buy this battery spot welder I can not find a website link to buy one
www.keenlab.de/index.php/portfolio-item/kweld/
Top notch
Thanks, bud - I'm proud of this one!
This is cool... can this be powered by a power supply?
You'd need one hell of a supply - this baby loves AMPS and lots of them and stupid fast at that.. I think 1000amps is a low spotweld current
Nothing to do with the welder, but why dont you install the strips in the opposite order?? So the "balance connection" last. the majority of the current (by far) is running in the series connection. now through twice as many welds as could have been...
How much total for this project? Not 9grand I hope
What my wall in total? Probably 12k total but that includes a bunch of mistakes
Would a 12volt lead acid leisure battery cut the mustard with this?
You would need the right type... These beauties pull some serious amps
look pretty cool, but not sure how to use a spot welder with my glass fuses :/
Let me test that for you :) Next video
