Thanks for the review!
Thanks for sharing all of this
Take care and god bless u always sir
Very informative content ❤make another series of diy spot welder
Ayos ang tips para maka welding
great review
I am waiting for my unit and very happy with your review, I think is very good spot welder and no modification need....Good video my friend best wishes for you
My friend your welcome! for me you better increase the traces from input point aria and also output point aria because poor quality of the traces! thanks.
@@pitikaron ok, I wait for your incrase trace video :)
I did it off cam! but installing five mosfet at the back I should be on cam to see what will happen after adding another five mosfet in tottall of 10. enjoy your coming weekend my friend.
What are the mosfets there IRF 1324S-7P?
IRL40SC209 it is a chinese mosfet due to code its not cleare like infenion from Germany
Nice
I ordered this spot welder from above link and MOSFETS are now different - F1324S-7P . On power 50 FOSFET died with explosion 😀
Sorry to hear that! I don't have any idea if they install a new type of MOSFET. Maybe you can replace the MOSFET 228 if the pcb board still functions properly.

Would be interesting to see whether you can spot weld a copper-nickel sandwich with this board or at least copper-nickel plated steel.
0.1-0.15 copper and 0.1-0.15 nickel/steel
I tried to catch up that in my part two
thanks for the review, adds to the choice of spot welder!
btw, sorry different from the topic
about spot welder dhj02b, is it possible to supply the MBTZ14S agm motor battery with 12 volts, 11.2 amperes, 190 CCA?
its alright you dont need to say sorry! as long as the voltage and the capacity of your battery it will not exceed voltage from the spot welder DHJ02B and also the amp c rate. according to the discreption of DHJ02B 900A.

thanks a lot for showing wtf this thing is. saw it on ebay and was a bit lost. ordered one thanks to you :)
what about using a 12v power supply? i have a basic old school bench supply and a few server supplies. they put out a lot of power.
Thanks also for dropping by my channel
You can use it. Separate power supply and the supply for welding but be sure it is the same voltage ⚡⚡⚡.
Amazing work😉
I will buy it anf use a car battery.
Any advice? Increase the contacts?
Thanks for the videos
as long as your car battery can produce 600A peak and the voltage must not exceed the ideal voltage for spot welding! good to go but you need to increase the traces of spot welding to avoid traces blown and also mosfet. more over wire input and output should also thick
thanks for visiting my channel
Hi Piti, thank you for sharing this new sport welder. Can you share the reference of those NEW mofsets that are supposed to be better than commonly used infineon 4n04r7/4n04r8 ?
Edit : you already provided the answer in a previous comment : IRL40SC209
Thanks !
Boss! base on my research on mosfet! N channel mosfet are better for DIY BATTERY PACK, because they have a quick response on & off ability. however you must not exceed the current limit of the mosfet to avoid mosfet blown up. other than that cheap spot welding from Chinese are very poor quality of traces! for that reason you must increase the thickness of the traces so that current flow smothly. anyway this latest spot welding installed IRL40SC209, 478A 40V RDS on 0.6M ohm and the max 0.8m ohms. if my response not clear for you are welcome to asked more questions. thanks for taking time watching my review boss.
@@pitikaron thank you for your answer. Looking forward to the next video with the trace enhancement along with the 5 added mosfet on the back :) That should bring a hooping peak current around 5000A.. Hoping to see a test of spot weld for 0.4 nickel plate and 2 0.3mm together :0
thanks boss! unfortunately it takes ages to wait my order from Ali-express.
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!

Hello,
I bought the same board for spot welding,
I am satisfied with the performance and function so far,
Do you happen to know how I can turn off this “auto-off” function?
It annoys me when I take a long break and have to switch the device on again and again
Greetings
You can create two power source, 12-16V power wall and the battery. The battery you used for spot welding power supply, wall power supply. a few CZcamsr call it power wall then the negative input From the battery goes to input welding board and the positive goes derictly to the test prove. By powering off you only unplug the wall power supply. And I think that's the only way.
Hello sir.What battery did you use ? It's nominal voltage and amperage ? I need the machime urgently but I'm not sure of the right battery to use
12V 8.4mah 100C for Lipo battery 🔋
If lead acid battery 🔋12V 500CCA. No idea for Ah. Anyway I provide a link for all the items I use in the description list.
got same board. Mosfet blew after 20 double spots at level 3 of 99
What type of the MOSFET install to the board coz I've heard a negative feedback that the latest model of this board installs fake MOSFET and That's why it blew up. But mind the first model it's still alive no issue I encountered.
If you can replace it by yourself I also have a video illustrating how I replace and what type of MOSFET I replace.
how can i make power input by ups 12v adapter for this spot welder
Kindly please go directly to the UPS battery and make your own output for your spot welder, hoping the UPS battery can produce enough current so that it can weld.
Hi. Thank you for this video. I am new to spot welding and it's very informative. I have a question. What is your metal test piece made of? Looks stainless but I'm not sure. Thank you.
I use a nickel strip ideal for 18650 battery started at 0.1 up to 0.3mm it depends on your need. There are 2 types of strips for Battery pack purposes I think! Pure nickel strip and metal strip/coated nickel.
@@pitikaron Thanks for the quick answer. I was actually wondering what material is the piece of metal plate that you weld the strip to for your tests? I think it's a very good simple test and would like to be able to do the same.
Aaaaah ok sorry it's a stainless steel 0.5mm from ali-express
@@pitikaron Right. Thanks for that. Off topic, but I've been nervous about using Aliexpress as their feedback to Australia is bad (I'm in Vic). I think I saw you quote Aus$ (mosfets?) somewhere. If you're in Aus, how have they been for you?
As of now I am already back home (Philippines) I live in Aus for 5 years as an international student Queensland. When I was in Australia the only apps I used was Ali-express so far The seller mailed me the item that I ordered! However most Ali-express products are not branded but it will work.
What MOSFETs are the best? I see mine has Irl40sc209.
228 & 209 are fit to that purple spot welding.
thank for the review..i have one question, is it possible to use 4S battery pack(16.8V at full charge)?
what is the maximum voltage to your 4S battery when it is fully charge?
@@pitikaron on full charge, the 4S battery pack voltage is 16.8V.. im not sure if the extra +0.8V can cause damage to the spot welder.
I think not coz the maximum voltage recquired to the spot welder is 16v
and the minimum voltage is 9V. sorry If I cant give you a 100% yes that it wont coz damage but if we follow the input power recquirement your battery maximum voltage is suitable to the spot welder.
How many 3s 1.500 batterys did you use to power it please
3S 12V 5ah to 10ah 50 to 100C it's good for spot welding.
Hi friend
Can i connect with power supply direct of 14 v / 3 A or not and what you me advice.
Thanks
yeap if the Maximum voltage of the battery is 14VDC
@@pitikaron the voltage its 11.1 und 1550 mah than i can securely charge with power supply with 12.6 v and 1.55 A but before that i will but bms its the best way and if there's anything wrong please tell me
Better to install BMS that can manage the voltage protection and amp protection
Is there any way to change to work with 5v ?
Yes! unfortunately need to replace all the mosfet controller! what I mean is the IC or microhip that give signal on and off to the mosfet.
Curious how you’re getting good welds with 0.3mm nickel at gear 15. I have to go above 90 to get welds that are strong enough to tear the strip. At around 40 is where they begin to take hold but I can pull most of them apart. Have you had these results on actual batteries as well? Any thoughts as to why I’d have to go so high. Batteries I’m using should theoretically be able to deliver 1170 amps.
What sort or battery are you using?
If needed to max the gear means your battery is not high discharge rate.
@@pitikaron two parallel 6s, 6.5A, 90C. Totaling the 1170 in my post. Seems like that should be enough :( MOSFETs get pretty hot pretty quickly too which is my only fear.
Are you sure 6S? Then increase the thickness of the input and output traces. Then use 6/8 gauge silicone wire, If you can? replace the wire of the Battery into 6 gauge and 8 gauges for welding pen.
Sorry, 3S. Oops. Going to try increasing the pcb traces as a next step.
would this work okay with 12v 7amp alarm battery
If 7amp then the max C-RATE or DISCHARGE RATE is 300amp it will work.
Hi. Is it possible to use this solder with Li-ion 21700 Cells 2S-6P (8,4V - 24AH - 210A Max constant current drain)? Thanks
If that's the max peak current it is possible but you should expect for current drop due to the plate not being thick enough. To avoid burning the MOSFET you must separate the power source for switching on/off and your 21700 cell pack for your welding current. But the power source/supply must be the same Voltage to your 21700 cel pack 8.4V. moreover 200A ideal for 0.15 nickel plate.
@@pitikaron Thank you for your really fast answer! I'm a "little" newbie" here... I didn't understood what you mean with "you must separate the power source for switching on/off and your 21700 cell pack for your welding current. But the power source/supply must be the same Voltage to your 21700 cel pack 8.4V". I was speaking about my power source battery, It will be a 2S-6P of the Samsung INR21700-40T 4000mAh - 35A. It would be better a 3S-5P (I have 15 of this cells, I will use another solder machine to build this battery)? With 2S I only have 8,4V at the maximum capacity of the cells... Thank you once again!
If you have 3S and 6P it is better 6×4=24
24×10C=240A. Inregards separate power source search power wall spot welding for 18650 battery so that its easy to understand. There's a video on that.
wow €27 for a complete kit.. only strange thing is that they give a strange battery connector instead of XT connector.. to connect it to sum sort of lipo..The probes also don't look high grade..haha ..but for that money i suppose you could shop around on Aliexpress for a better option..
Due to the low price it doesn't seem good quality, however it worked firmly. For me due to low cost Labor and multi produce that's why they sell cheap.
wonder if this battery would be ok to use an 8000mAh 11.1V 100C 3S Lipo Battery
I purchase from ali-express 8400mah 3S 12V 140C and it's work well, more over I think I provide link for every item I showed in the video.
@@pitikaron Thank you for quick respond so then an 8000mAh 11.1V 100C 3S Lipo Battery should work fine tnx again
Yeap the most importante is C rate or discharge rate
Hi! Any test using lead acid car batteries? I have some 45Ah-100Ah (capable of 800Amp at 12V) but in the manual they say it can burn the welder and I have to use max 45Ah and at least 1 year old lead acid car battery.
From Ali description:
"The old lead-acid battery 12V 20AH-100AH (the new battery cannot exceed 45AH) and the 20AHI old lead-acid battery cannot exceed one year. The older it is, the bigger the capacity.
Or: 4-5 strings of super Farad capacitors"
I am not sure if I understood well, maybe 20Ah must be max 1 year old and 45Ah can be new,but 45-100Ah must be many years old.
And where to put the super capacitors? Shoukd they be in parallel and I could use my 100Ah new battery?
Sorry I never had to try using a 100Ah lead acid battery. Moreover I don't have any idea the difference between lead and RC car battery. My advice is just compare the specification of lead acid and RC car battery and if it is relevant or similar then I think it could be useful but remember I never had a chance to use a lead acid battery. But for your safety just stick to it to your 45ah I think.
@@pitikaronthank, as I understuud there K99 spot welders have no current limiting and the required gear ratio also pased on the battery pack used. So I have to make experiments. I saw at other videos on litium ion 4S4P it required at least gear50-60 to weld a 0.2. litium polimer (RC) have high C compared to ion and also lead acid car batteries have high amps for short period but gread internal resistance.... so will have to check, I am waiting for my welder kit to arrive.
I have my car batteries used for my solar buffer but turned out not working well so using 7S120P 18650 pack for solar now from recovered cells.
Nice I hope you will be successful with your experiment.
Nice sharing. Irl40sc209 is logic mosfet. Can it weld with 5v (series super capacitor)?
The voltage requirement is 9-16V better to supply 12V 6100Mah 100-200C discharge rate if you want to supply supper capacitor kindly please supply 12V with 1000A do not exceed 1500A to avoid mosfet blown better
Thanks
Thank you too boss
I have this model and work perfect with 2 units 3000F super capacitors in series....only need an external power supply with 1amp minimum to turn on the board
@@francisconotengo3477how do you do it ? 3000F is 2.7v, so its 5.4v with 2 series, and board required 9-16v supply. What is voltage for external power supply ?
what wire guage to use for this welder?
From battery to the board 6 gauge from board to welding pen 8 gauge
How many amps is ur battery pack rated to?
3S 12V 8000mwh 130C 800A peak current
hello guys. what is the maximum ampere that can be used for the spot welder machine ?? and can i use input from xt60 interface ?? not the input of the plus and minus cable ?? thanks
It depends on the mosfet that they installed to your spot welder and the current limit of the mosfet. sorry I Don't really get it your next questions. power supply input positive and negative? as long as you can power up your spot welder it doesn't matter howerve it is better that can handle or manage large current.
@@pitikaron the one in the video. I see that there is an xt60 input socket. Can I install xt60pw on the board and I want to use a 5200mah 80C battery.. can I use that battery sir?? sorry i can't speak english so i use google translate...
Yeah you can manufacturer provided for XT60 SLOT but please do not enterchange the positive and negative, their is no protection for wrongway installation. you can also refer to the seller advertisement or email the seller where you can install XT60? anyway if you did not add/install another 5 mosfet at the Back the maximum current you can used only 2000A coz that 5 mosfet can handle 2,390A but leave extra for current flactuation.
@@pitikaron ok.... i will try to install xt60 slot... on the media it says + and - in body xt60 sir... so it won't be reversed...
thanks sir
if i may ask to make a video using xt60 slot... can you make a tutorial sir?? Hehehe
please sir
@@pitikaron I've subscribed sir.. I'm waiting for the soldering tutorial and how to install xt60... hehehehe thanks for all the answers... it made me learn
Sorry for maybe a dumb question. Do you have a video on how you put your battery packs together?
What kind of battery? This battery its not really good pack it is better for to buy 8.4mah 3S 100C I think I provide a link to the description below.
@@pitikaronthank you for getting back to me so quickly.
The 1550 yellow batteries. 100c/200c. 3s1p 11.1v 17.2wh. I think this is the correct information on the batteries.
I now see 2 positive lead wires joining together and 1 red wire you are using for a ground. I couldn’t see the backside of your batteries.
Yes according to the seller and the brand is Gaoneng. 1550mah 3S 4X of 3S 1P I replaced the stock 12 gauge wire into 10 gaugewire and I connected parallel so that the voltage still the same 12V 3S 4P so 1550mah × 4= 6100mah × 100C = 6100A burst current
@@pitikaron
Thank you again Piti. It looked like 4 cells to me but I got confused when I saw 3 red wires and no ground at first. Then I saw you hook up a red wire with black tape to ground I figured maybe 3 ground wires and 2 more hot red wires were on other side of pack.
Actually it is all red wire but to make it sure that I can't mess up connection/flug in to the spot welder I wrap with black tape for negative Identification. The configuration is just connecting the four types of 3S 1P battery into parallel. If you have an email I will mail the photo to you.
Hi Friend . Very good video thank you for infos . Recommend you to wear gloves , the nickel is can cause cancer or birthdefects stay safe. best wishes
Thanks for you giving me advice
Nickel those none of that !! But maybe it gives you allergy to nickel if your body is allergic to it! At most rashes that itches . The metal you are refering to is not nickel but lead (pb)
I am just based on the seller description and I don't have the right to change the description because I am a buyer's not the strip inventor
Just a question. I see you recomand everyoane that the car batt is capable of 500A discharge. Just curios where does it say that? Because the manual states that if new, the car batt should not excede 45A capacity, well good luck on finding a car batt that is 45A and can do 500A. I've bought a 44A (390A peack discharge) that's how they usualy come. I've seen 500-600A at batt of 60-75A but then you're not as by the manual with the 45A limit. They all talk on videos about this device pulling 300A. So..where is the 500A number come from? Thanks!
If I recommend the car battery I am so sorry, but I reviewed my video I didn't say anything in regards to the car Battery that can discharge 500A instead of doing a review if the spot welding machine can work well/weld firmly. Anyway one comment below asking me if he/she can use the car battery and I said yes as long as it won't exceed 16V and can also manage/discharge 500A?
@@pitikaron Yes, that is are the comments regarding 500A. But nevermind..I was having trouble spot welding and seeing your comm I thought my batt is low power but then I've found I was presing too hard on the tips and then even at max power the spot welds are weak. Several people were talking about that on a vid comments, glad I've saw that. Now at a quarter power makes strong welds if I just barely touch them..
Yeah don't press to much, as long as the two TIPS contact to the NICKEL STRIP it will weld firmly but base in my experience I push enough strength so that the nickel strip and the battery contact firmly.
45Ah(amp hours) and a car battery can deliver up to 2500A!! Short circuited. That is what you are doing for the welding.many people look att cold cranking amps CCA and that is wrong ! The short circuit amps is several times that! This controller should be modified so you don't blow up the FETS. and use several high amp diodes from minus to plus of your baytery
Hi, i see that with some spotwelders they connect the positive directly to each other on the pcb. Is that better? Regards
Kindly please explain further because I can't figure out what you mean by it? Sorry.
@@pitikaron czcams.com/video/9I5pJyM8DKk/video.html
@@pitikaron if you look at the video you'll see that that positive leads are directly connected. I wonder if that's a better configuration? Regards
Directly connected to spot weld tips or positive power sources? If that's what you mean by it, basically that's how it goes. If you think you could add more for protection it is better. But spot welder design to release large current to melt the metal.
@@pitikaron if you look at the video you'll see that the positive from the battery is directly connected to the postive welding pen. that's what i mean
Hello, i think mine blew a mosfet or several. It burns holes and sparks fly. Is it possible that it might need a capacitor mod like other spotwelders? And it is possible to specifically determine which mosfet is blown or do you have to desolder all from the board and check individually? Regards
If that is so there is something wrong with the microchip controller timer.
@@pitikaron how do i check the mosfets? Regards
Check by multi meter? You can also search on CZcams how to check MOSFET

if you have B6 charger for lipo battery so you dont need to install BMS for charging input. no dont coz you short the battery do not join the wire every cell
Can I use a car battery
Yes as long as the voltage cannot exceed 16V and the pulse amp is 500A
the batteries in series or parallel
Battery power source?
@@pitikaron yes, the input source, because I see there are 2 xt60 connectors
First I buy 3S 1550mah but the current is not enough so I purchased the same spec & I see the current increase so I purchased a third time but 2 pack of 3S 1550mah 100C and I connected in parallel. So the total is 6100mah. However if you have a plan to purchase, choose 3S 8500mah 100C. There are so many high drain battery packs in ali-epress.
Are those pure nickel strips?
O.2mm is pure according to the ADS of the seller 99%
You can tell in 10 seconds. Take your Dremel with cutoff wheel and cut off a couple of mm's. If it's nickel plated steel, you'll get a great spark show. If it is pure nickel, you get zero sparks.
Thanks for your secret information I'll do.

I think if you actually tried to shove 250 amps through one of those fets you would end up with a small, stinky fire. I have one of these and there is no way in hell they will take that type of current. Milliseconds worth maybe.
Base on Fets spec, it can only manage millisecond even 800A.
@@pitikaron Just was using mine with a BMW battery...950 CCA/105Ah. Plenty of juice. It's so nice to not have to worry about heating cells with an iron to make packs.
Nice 😉😉😉
Why look at CCA when you are actually shorting the poles of the battery to weld?!! You should look at the spec SCA ( SHORT CIRCUIT AMPS) and I promise you its several thousand amps! From 1500 -2700A for the car battery you mentioned. For that battery you need to modify the board (simple) to not dip in voltage too much and use several high amp diodes from minus to plus of the battery otherwise you'll blow up you fets guaranteed
You have lied some body.
In your free justification
Cannot understand nothing you’re saying all you do is mumble

i just got mine, i connected it to a 3s5p battery and tried to weld on 04 and the fets just burned out completely and the strip melted, what fets should i get?
Check your fets if it is IRL40SC209 then replace IRL40SC228. Before replacing fets kindly please check the resistor head to gate if it is still fit or not short or leak? anyway I have a doubt why the fets burn coz my spot weld it won't even I supply 3S 4P 6500Mah 100C up to 200C at this video coz I produce another part and I think I supply 3S 2P 8400Mah 120C-240C?
