I do like the way you finish/house your projects especially this time giving everything a bit more space. Do let us know how the battery performs over time.
the 90-120 amps required by the spot welder is for micro seconds so its okay the given components can handel this job but if you are building very big battery bank then you might need to take a little break to cool down the cables. for 11$ it is good looking
Nice. They used a machine to install all the SMT parts and reflow soldered the board in an oven, the through-hole parts have to be manually installed for more time and money, and it’s much easier to do, just time consuming, so they leave it to the user.
I think they left those two components for the user to solder because they are trough hole components that can't be soldered automatically, and thus are more expensive to ship all assembled.
They do it to avoid damage. These passives are relatively heavy and the packaging usually sucks. Vibration or rough handling during transport can damage the components or solder joints. Their safest bet to avoid complaints is shipping these parts separately.
Excellent video for instruction, very professional and awesome audio explanation with clear video. Many should follow your style. Your assistant is also to be commended.

Great video Sorin, with that size box you could use a small solenoid between the spot weld PCB and leads which could break the circuit at the same time as the 2 x H7 bulbs you used.
I just made a spot welder with a microwave transformer and I suggest you do too 3.3v 580a and no need to worry about charging and battery degradation 0.2mm strip is nothing for it haha
A colleague of mine has a similar kit which he uses quite often for spot welding DIY battery packs. He's now thinking about making a spot welder from a microwave transformer because he might change the battery as its performance dropped significantly within two years. Maybe you could sometime make a spot welder from a microwave transformer?
Maybe he should just buy another battery. That's not too expensive considering it lasted for 2 years. They don't last forever. I regularly change out the batteries for my miniquads, and thats like 15, 4S batteries.
@@minkorrh That's the point. He doesn't want to buy a new battery every two years. If you have a transformer operated spot welder, it will basically last forever, if constructed well.
Brilliant content! It's most likely that the amp rating on wires is continuous discharge and will be able discharge 2-3 times for 5-10 secs even 4 times if sub 1 second discharge
Thank you for this video I purchased one of these spot welder is exactly the same as yours and I was impressed with the performance I haven’t really got any battery packs yet with it but see what you have done is give me some ideas and has given me a lot more confidence to go out in a full build of the spot welder project I use a disabled scooter battery for my spot welder but think I might invest in a lithium polymer batteries for the billed Thanks again for all the projects and good ideas that you put out on this channel I really look forward to the next one on the big hi from the UK stay safe
@@bobravenscraft5376 Yes I think you are right I’ve been using a very large lead acid battery and it works fine I’ve now finished my disabled scooter battery just bought an active balance board so I can keep it in balance even though it’s got A BMS all the batteries are different mics I’m slightly out of balance
That spot welder kit you bought is garbage i bought 2 of them and the both blew up before i could build a 10s 10p battery the mosfet on each board let put the magic pixie smoke
that's a very cool spot welder Sorin!. : ) well worth the few quid you spent o it.. i think i'll make one for myself, lord knows i need one. : ) THANK YOU FOR THE VIDEO, IT WAS CLASS!!
Components are through hole, its cheaper to not solder them on and just ship them with the package. Through hole components need a solderbatch to do large batches wich is extra cost for the manufacturer.
With high currents i usually ensure only good contact but i never solder because it will increase contact resistance (is solder makes its way between copper parts ) producing more heat
Nice Project. the only mods i would make are a set of heatsinks on the mosfets and a fan to keep them cool thus extending their life and a cut off switch on the lid so it cuts power if opened thus to prevent any small conductive materials from falling in when open and being missed the one device you dont want to let out the magic smoke. ... or a shock yourself when disconecting the battery pack
Very interesting and useful video. Specially thanks for attention to great details, that made me confident to assemble similar DIY kit. Which already bought components but not yet tested.
They let you solder the last components yourself because they are through hole components. If they have to let it solder in the factory, it is an additional step that comes with high cost compared to SMT assembly.
Hey, I just found your channel and I have to say that your content is A+ quality. It was interesting and informative! Great video Sorin! Also I subscribed to see your future projects on time!
I just ordered stuff. Of course it will take 2 months for everything to arrive :) I used your affiliate links so I hope you get something from it. You did a good job explaining how to assemble, so I think I should be able to do it as well. It cost me 65,07€ all together. Cheers
I just did it! Based on your instructions! Thanks man for clarifying everything just enough so it was possible to repeat all the steps. I did not do it completely the same as my box was too big, so I just used a back plastic plate for it. In the next couple of days I will try to spot weld my first battery pack. Now, only the sky is the limit :D Cheers!
Good demo and advice on charging levels for lithium-ion batteries as well as the intro to types I wasn't aware of until now. Btw, like your cute little inspector checking things out 4u.
I like this video, and find the humor refreshing, thanks. For future reference... as you've mentioned in the video itself, the welder is not "home made", only a kit with a battery. Although click bait titles are sometimes essential to attract viewers, in this case the truth would have been better (imho), i.e. something like "very powerful spot welder kit" instead of stating "home made" in the title just to reveal the truth in the video itself. Keep up the good work.
This is a great build. Very simple and super useful. I have been thinking of getting one of the prebuilt portable ones for my channel. However this looks great too. I might try your approach and make a video for it.
This is exactly what I am looking for. Dose the key points on the cct board appears in second 50 ,If an external switch is attached to the circuit, will it compensate for the use of the internal switch to change the welding current?
3:00 The components are not soldered because a) they're through-hole, so that would be a completely different process to the SMT components already installed, and b) they are the only components that most hobbyists are able to solder reliably anyway. Also, the ratings on the lugs and connectors are for prolonged use. No problem to send 10x the current, if it's only going to be for tenth of a second. The problem here is rather the current being way to low for proper spot-welding. Industrial spot welders do the welding in less than a hundredths of a second, and use capacitors for that reason. Batteries just have too high of an internal resistance.
Interesting how he liked only the comments that stroke his ego, constructive criticism seems to bother him. Also I was wondering why go through a hassle to build this when we have more refined products to buy for as low as 20 euro? I like to build stuff but it's usually when I cannot buy the thing I need or I need to improv. Good comment btw.
gee whiz... kitty kats help out on a lot of projects, also doggies like to help for a treat...:) seems to be the thing in a lot of countries... which show people have similar feelings...:)
A very good project and helpful 😀video construction, Sorin! I will make one spot welder like yours in the next times to solder LiPo 18650 packs for my rc submarines. Have a very good New Year 2022 and regards from Spain!
Looks like its a doable project for a novice (👋😂). Instead of using a battery can i use a laptop charger connected to a boost converter making sure i keep to 12v? Excellent video, nicely explained👍👍
Another great project Sorin, honestly its video's like yours that give me enthusiasm to build thing and bring idea's to life.
Keep up the great work !
It's channels like this that make RUclips great. Thanks Sorin! Liked and subscribed.
Thank you for sharing your eyeball engineering, great job.

You should invest in a few small wrenches. Nuts don't like being tightened with pliers.
Thanks my favourite chap from Romania!
How come this is the first time I come across this channel?! You rock man!
I like it, it is perfect for DIY battery packs (and don't need the use of pedal switch) thanks for the video .
Nice conversion kit.As always from you Sorin nice tutorial
Very good video, good explanation, perfectly understandable. Thank for sharing. Good work
Very nice sorrin ! Again u made a great video !
With high currents i usually ensure only good contact but i never solder because it will increase contact resistance (is solder makes its way between copper parts ) producing more heat

The mosfets don't seem to have any driver circuits, so they will spend a lot of time in half-open/half-closed state and high-resistance.
Nice job Sorin 👍👏
You covered lot of things in single video ❤️❤️❤️ thank you. 😁 Feeling happy after watching this video.
Sorin - Vendor does SMT process, which is low lost. Thru hole parts requires more human labor, which is why customer does it.
Homemade or assembled at home 🙂
Real test is to weld 2 strips together, I have the same welder and I couldn't do it.
I sure do like this guy.
Very interesting and useful video. Specially thanks for attention to great details, that made me confident to assemble similar DIY kit. Which already bought components but not yet tested.

Assuming the board is wave soldered. Less cost if you solder the chunky bits instead of them.

Am apăsat like dinainte 😉
This is exactly what I am looking for.
Dose the key points on the cct board appears in second 50 ,If an external switch is attached to the circuit, will it compensate for the use of the internal switch to change the welding current?
yes, you can add an external switch. but the switch doesn't change the current, it only changes the welding time in milliseconds.
After connecting the battery, I did not go blind. (Sounds like Homer Simpson when he made his new drink, the "Flaming Homer").
Close to 3 years later, I'm finally making it with the same kit. :)
3:00 The components are not soldered because a) they're through-hole, so that would be a completely different process to the SMT components already installed, and b) they are the only components that most hobbyists are able to solder reliably anyway.
