Morten I just looked at the Banggood page for this device and they have attached an English version pdf file for the instruction manual. They've also got a more expensive version that has replaceable electrodes but doesn't seem to have the same features. I'm an amateur radio operator and in the past I've rebuilt battery packs for my portable xcvrs and they were a bitch to solder. Also a lot of my hand tools use rechargeable batteries and it would be a lot more cost effective to rebuild the packs rather than buy new ones. Rebuilding 3 battery packs would pay for the welder imo so I'm going to place an order. I've bought a lot of things from them before and the only complaint I have with the company is the long lead time. I also noticed they have nickle tape rolls so I'll probably get one of those because I know I'm going to have to practice with it before actually using it. Thank you for an excellent video. John.

@@MyPlayHouse I was shocked this afternoon to find the package from banggood outside my front door. That's the fastest turnaround yet from them. One of the uses I intend to put it to is rebuilding defunct Black & Decker battery packs for some of the tools I have. Mind you I replaced those tools a while back but I abhor throwing potentially useful items out. I found a source on Ebay that sells the sub c 4/5 nimh cells so I can rebuild the packs for around $15. It was minimally charged when it arrived so I haven't had a chance to test it yet. The defective packs I have will be the guinea pigs for the testing. Thanks again for making me aware of this tool.
@@MyPlayHouse Morten, I just wanted to give you an update. I ordered some sub-c NIiMh cells to rebuild the battery packs that power my legacy B&D products. There where some vendors on Ebay that were selling "new" packs but considering this equipment has been discontinued for quite a while I decided to rebuild the packs I had. The new cells came with tabs which made the process easier but I tell you from having to try to solder wires to cells in the past this spot welder is p!sser! One electrode holds the tab in place while the other completed the circuit. And, as you pointed out, setting 2 does the job. Many thanks, guy! You saved me from throwing good equipment out.
4:55 If you receive a device with manual only in some strange language, scanning it and using Google Translate does a good job. Translated version usually isn't perfect and you still have to guess many things, but at least it's easier than reading in chinese.
For the Chinese manual, open your android phone with 'Google translate', there is any option to point the Camera to the text and it would try to translate it to English. It also works for other languages such Japanese to English or Korean to English or whatever. The translation should contain 1/5 of jokes, but it will leave enough clues for your guessing. The translation will appear in the screen, it is quite handy. For the sharp pointer electrode, it is a hard alloy of copper which contains silicate or something, it is more durable than pure copper as those in the connection wire.
I bought this welder after watching your video. I just tried it and was having problems. I could not get a solid bond between the ribbon and the battery or between two pieces of ribbon. Used my Dremel to sharpen both electrodes and Bob's your uncle. Works a treat.
Make sure you're not applying too much pressure - you want high resistance through only applying very light pressure for best results. The fact that sharpening the tips worked is pretty good evidence that was the root problem.
@@anticapitalize Sharpening might not have been the issue. Copper can oxidize a layer you can't see but effect performance. The sharpening could have just removed / cleaned the oxidation and it wasn't the "sharpness" that actually fixed it.
Neat little thing and yeah it only runs about $67 where I live (in Canada). Some of those other $25 ones on Amazon look a bit sketchy. This thing looks nice.
Spot welders need a bit of resistance between the two metals to work well. If you wrap the fuse wire around the copper, you make the connection too good, and so the highest resistance point is somewhere else, for example between the probe tip and the fuse wire, resulting in most of the heat being produced at that junction instead. I think trying to spot weld the fuse wire to the copper wire is a bit tricky because to get a high enough resistance, you need to have it touch without wrapping, since both conductors are essentially cylinders. You might try putting one short section of the copper wire on an anvil, and hit it with a hammer to flatten it out a little. That will give you a "line contact" instead of a single point contact.
High setting is probably for tin plated copper strip. Copper has lower electrical resistance than nickel but requires more power to spot weld because of this. The reason they use nickel is because it's easier to weld due to the higher electrical resistance.
That second spot welder the banggood one, what you need is a 30amp fuse in the plug and back of the machine and depending on what circuit you are using, i had to swap out the circuit breaker for a 32amp C breaker for high inrush currents.
Very nice :-D, controlling the duration of the discharge to make it the same every time. And your probes have to be on the strip before it fires, better control. Clever little box, i bet they took a while to get it optimised. Along with the small area probes, control again.
When i opened mine i felt nervous about the one side bare terminals being so close to the base metal casing of it so i slipped in a thin piece of plastic to isolate it from the outter casing. I mean its unlikely it would ever touch but it was just one them feelings and these batteries are the violent explode type.
Thank you so much! I'm trying to make my own custom cookie / polymer clay cutters, but unfortunately aluminum can not be soldered and using rivets is not the best either. So I do will take a look at this. I was wondering if I should make my own, but it would cost just as much in parts as this.
It probably is a one trick pony, but it seems to do its trick rather well! Nice little device, really! At first it seems counter-intuitive that you'd be able to power a spotwelder from such small power sources, but what the spotwelder does is taking the power provided to it over a long time and release it in a millisecond or so. The great advntage of spotwelding is that you don't put a great amount of heat into your parts to achieve the connection after all! So Bob's your uncle, Pocket-Spotwelder Olé! :oD
I bougth a very similar one and found myself having to use the max setting to achieve the best result. The one you have seems to be a nit better. At the end it got the job done and it did not break the bank.
I don't like how the connection for the welding "probes" (don't know what to call it) are surface mounted, especially because they require some force. I think that'll probably be the first thing to break. Maybe it's best to put them in and never take them out again
@@MyPlayHouse I have a similar unit, different layout PCB though, with the same battery setup, I removed the spot weld probe sockets and ran flexible 8 gauge cable straight through the holes in the case and soldered to the board/copper bars, and it welds quite a bit better. Now able to do 0.15mm Pure Nickel welds reasonably on max setting where it did poorly before. Connectors or any added PCB resistance is super important on spot welders. Note: If you do this don't make your leads much longer as longer leads result in higher inductance and the resulting voltage spike during the weld may destroy your MOSFETs
Also friends I know it is best to grind off the remains of nickel tabs from reclaimed batteries for soldering but is it as good for spot welding??? Some have said to leave a small amount of nickel on the batteries so that you can weld on to them??? Is this correct or should I grind it all off and start from scratch??? Best regards, Scott. ✌️🙏✌️
The US Amazon site has all of the specs in english. Theirs is listed as having an aluminum alloy shell. $67. w/ free shipping on 3/23/21 Amazon has a good return policy too. Can you test the output by putting the tips on your tongue?
Well you know the US is only 5% of the world,, and for us outside, returning is not really an option. and the Spot welder is like $20 cheaper from China. I would not test anything that melts metal together,,,on my tongue.
Did you use pure nickel or the roll that came in the box? The box roll was nickel aluminum. I tested it in water. Point is if it's .15 or .2mm nickel it would have alot of good uses...I own one and haven't touched it sense
Hey friends. Great video. I have the same spot welder but have had problems using anything thicker than 0-1mm. I would really like to know what connections are they using from the pens in to the unit. Are they XT150 bullets as I have bought some pairs and plan to extent the cables to 12inch I’m total using 8awg silicone cable. Am I correct in thinking these things above and will it be of service as I doubt the cable they provide which is said to be 12awg and would I get a better welding experience using 8awg at 12inches or longer??? Thank you kindly friends!!! ✌️🙏✌️
I don't know if you care, but it seems like you used a bit high current or camping force. Decrease either of them and the yield strength will be higher. I could see some small sparks, which means that here is material not only being rmeoved from under the tips, but leaving the area of the joint all together.
If I used copper strips instead of nickel would I get a better battery in practice or is it like a meaningless improvement having the better conductivity of the copper. I think it's like 22% for nickel vs 100% conductive for copper, sounds big but is it actually noticeable???
Saw this product on bangood a few days ago, was wondering if it is any good... I figured i'd take the chance for the price, it is nice to see it reviewed. My only complain here is that the interface is not the best, but again, it is cheap. But i'd like a slighly more expensive version with perhaps a tiny oled screen and a few buttons for more settings...
@@MyPlayHouse i meant one of those small monochrome oled displays, as on the TS-100 soldering iron, it is 128*32 pixels; super crisp text, low power consumption, and it costs 1-2$ per lcd (i2c interface) from the usual chinese stores :) It allows to print values on the screen (for the TS100, you can see the celcius (or farenheit) degrees, rather than 4 levels of power), and thus you can have more precise settings, know the settings exactly (here you would print the amperage output, and the pulse duration, for instance... and having those settings may enable you to succeed the spot welding on copper) Anyway, cheers!
Hello, I like your video thank you I was looking for some thing for my project which is soldering copper wires to break a infrared panel LED lights. Soldering is not my forte, so I think spotwelding could be better.
I've tried this one after some good UA-cam reviews, but I could only get 0.1 mm pure nickel to stick reasonability well. For some more serious battery packs, this is not enough. I've ordered the KWeld from Germany, and that is some much better. Even on low settings you can weld 0.2 very easy. A bit more expensive, but worth the extra $.
I don't know what I'd use it for but I want one. It doesn't look like it could handle bigger projects with larger pieces that I have in mind but I have so many tools that I've only used once what would hurt having one more?
Helpful video as just about to replace 18650's in my Makita, would this weld the metal cage that holds and connects the batteries, probably a bit thicker than the nickel strips that are shown in your video, many thanks
What are your thoughts on whether or not this thing could be used for simple tack welding, such as for tacking a nut to a washer or metal frame just to hold it in place long enough for a bolt to be threaded on? I realize the tack might be very small, but perhaps several spot tacks around the perimeter (of the bolt or washer) for example might be enough for this purpose? Also, how about use as a "lock-tite" equivalent to hold a nut onto a bolt (so it doesn't unthread easily)? Just wondering if anyone has ever tried this with any success.
This is for very thin matrial,,0.1-0.15mm and works very well with these battery strips,, not much more than that. I was told that it has problems with 0,2mm.
@@MyPlayHouse Thanks, just the same I purchased one and will give it a try on my proposed application and let you know how it turns out. Back to you later
Can the probe wires be replaced with larger gauge wire in silicon test casing without hurting the welders performance? Then I could mount the welder on my lab bench.
Will this spot welder connect small metal pieces? I build custom die cast cars (hot wheels size) and want to build small roof racks to fit on them. What do you think?
@@MyPlayHouse Great video ! First your video and I suscribed right away :) LOL - "safety" slippers ! I had a good time watching, very refreshing - you are natural with great sense of humor but I got all the info too, now I know this spot welder like I have own it for 6 months.... :) PS: BTW, we Petrovic (Peterson - translated) can be useful and even smart - at least sometimes ! LOL :) Thanks (to you too Danilo) again, cheers !
Wouldn't it be nice if you could buy cells with little tabs on the ends so they could be entirely soldered with no chance of damaging the cell. Nice little machine though!
I bought the $24 dollar green one that doesn't have the battery. Made a 3s battery for it. It works perfectly at level 18. Don't buy the one made to run off capacitors. They blow up.
When I received my spot welder, the battery measured about 0.5 volt. It should be a value of 3 volts or more to be on the safe side. I put it on the charger and after charging very slowly for about an hour(0.1-0.15A). Then when it reached about 3 volts it was charging for a couple of hours on 1.1 amps max. Eventually it reached 4.19volts and was ready to use. I grinded and cleaned the contacts on a 18650 lion battery and a AA nimh battery. Tried different output levels (1 red light till 4 red lights). The performance was very poor. Even with the included 0.1mm nickel plated strips. The nickel strips do not stick well to the battery. I can easily remove them so it is not a good connection. Probably it is caused because of a poor battery. Maybe with a good battery it can weld the thinnests 0.1mm strips but definitely not more than that. There are more people receiving this spot welder with an almost empty battery. Maybe the included self discharge circuit is faulty. I will not recommend this spot welder to anyone because it probably only works well with a new battery. If the battery ages it will have the same problems as I have.
Nice review. I'm a bit concerned though that it could not melt copper. Although you may need higher melting electrodes but 600A should melt copper depending on the on time.
It doesn't work on copper because copper is too good of a conductor. To generate the heat you need some resistance: P=Isqr*R. The nickel strip will melt but not the copper, so no weld.
Use binder page reinforcement rings for holes needing repair as extra insulators for the positive terminal of 18650 batteries. Thanks for the review, I was just looking at Bangood little spot welder this morning. Take care.
I am VERY IMPRESSED!!! I agree with you on the build quality looking VERY GOOD... ESPECIALLY for only about $50 !!! WOW!!! But like I was stressing in the top pinned comment PLEASE periodically open it up and check THE BATTERIES to see if they ever start expanding or "pillowing" - cheap Chinese batteries are NOTORIOUS for 'exploding' and really what can you do if it burns your house down? Who could you sue for damages? Do you even know who sold it to you? Are you sure they have closed that company down and started it back up under a new name?>? This happens A LOT with the CHEAP Chinese products.... So EVEN THOUGH it looks like it was build VERY WELL, there is just NO WAY to know if that battery has such good quality... So the ONLY thing you can do to protect yourself if to regularly check them... I don't think they go bad just by sitting around not being used (especially since it automatically drains to 50% after a few days without use) but that is a CLUE that they may already know the batteries aren't the highest quality - I have NEVER heard of a company automatically drain their batteries like that... and so that is a RED FLAG for me.. I would keep it AWAY FROM other things that could burn, and in an area that would let it spread to the rest of belongs and house.... The MORE you USE and RECHARGE it, the more risk you have - so PLEASE CHECK THOSE BATTERIES REGULARLY!!!!! :D - - - Oh and THANK YOU for find and sharing this!!!! Having a small spot welder came across my mind while building not too long ago, but I managed without it. So if I had this it would have been VERY HELPFUL.... so I think I will pick one up and put it to use!! THANK YOU!!! :D
@@MyPlayHouse Thank You. I did a little research. My understanding is that spot welders are relatively safe compared to arc welders because they only heat the metal. The arc of an arc welder generates harmful radiation which is not present in spot welding. Dark tinted glasses are recommended by some for spot welding however.
Nice video, what other use is there for this welder apart from sticking batteries together, can you solder or join other metals together like making fitting for model boats perhaps? Thanks.
Used your link, and just bought one 😃 good enough for what I’ll need it for, and I can easily replace those leads if needed. The auto-discharge feature sold me on it. 😎
auto discharge is a pain in the ass. prevent you from getting good pressure down before it fires. especially with thicker gauge nickel strip for high power applications.
Nice device after inprovements are done :) Improvement #1 make new longer cables with more beef and insultate to the very tip. Improvement #2 a fixture to attach the box to the desk or similar
I just purchase the exact same one and even after watching your video at least ten times and ensuring the settings are correct, it doesn't produce enough power to spot weld the strip on the batteries. It feels like it's stuck on level one, but it's on level 4. So frustrating. (yes it's fully charged)
This type of spot welder couldn't be used to weld a Chrome Molly 4130 mtb bike frame together could it? Please excuse my ignorance. I'm new to learning about welding. I did take a welding class in high school once, but that was a long time ago(cars were still made out of wood, haha), and I've already forgotten anything that I did learn. Thank you for the great video!
For the average person that will be spot welding 18650 batteries off and on when the need arises for small projects, its works well and very reasonably priced, and btw... theres a youtuber by the name "Sanchai" that reviewed this very same spot welder, tested by welding two peices of nickle strips together, from the lowest to the highest setting, it will not weld .2mm hardly at all, so for best results, use .1mm or perhaps .15mm the most.
As your helpful video shows the spot welder quickly and easily creates an adequate mechanical connection with little danger of damaging the battery due to overheating. However the electrical connection may not be as good as soldering. Spot welding creates a tiny contact area compared to soldering. Presumably this would create additional resistance, although perhaps not enough to matter.
i would have prefered a 18650 as internal battery , at least u can replace it quickly and easly if needed , cos i dont think that battery in there would be easy to find .
Only thing I don't like is the welding leads. I'd prefer to have a screw terminal/clamp to attach leads so I can make my own out of a piece of 10 gauge stranded wire with a copper wire form a length of romex as a tip. That way I can have whatever length I need, and have different shaped tips.
@@MyPlayHouse i think I'm going to just avoid welding entirely. Nickel isn't really much good for high current battery packs. My pouch cells will be mechanically connected with threaded aluminum rod to avoid corrosion. For my 18650 pack I'm going to order some high conductivity silver based adhesive to bond coppet bus bars. With the 18650's I can pull 30 amps per cell, and thats just too much for nickel. And the pouch cells are up to 200 amp continuous, 400 amp peak.
I am using such a spot welder now quiet for some time. I paid only USD 26, maybe because I live near to China. I do a lot of spot welding. I therefore can confirm that you weld at least 250 spots before recharging the box. I wish you happy welding. You can replace the copper welding electrodes by simple copper nails.

Mind you I replaced those tools a while back but I abhor throwing potentially useful items out. I found a source on Ebay that sells the sub c 4/5 nimh cells so I can rebuild the packs for around $15. It was minimally charged when it arrived so I haven't had a chance to test it yet. The defective packs I have will be the guinea pigs for the testing. Thanks again for making me aware of this tool.
@@MyPlayHouse Morten, I just wanted to give you an update. I ordered some sub-c NIiMh cells to rebuild the battery packs that power my legacy B&D products. There where some vendors on Ebay that were selling "new" packs but considering this equipment has been discontinued for quite a while I decided to rebuild the packs I had. The new cells came with tabs which made the process easier but I tell you from having to try to solder wires to cells in the past this spot welder is p!sser! One electrode holds the tab in place while the other completed the circuit. And, as you pointed out, setting 2 does the job. Many thanks, guy! You saved me from throwing good equipment out.
4:55 If you receive a device with manual only in some strange language, scanning it and using Google Translate does a good job. Translated version usually isn't perfect and you still have to guess many things, but at least it's easier than reading in chinese.
Thank You,, I do know that trick :-)
Eesh. Spot weld the nickel strips but solder the wires. Also, agree, maybe put some shrink wrap around the unit. Some of the rubber type stuff.
It is just the first 10-20 welds, where you think about touching the metal.
For the Chinese manual, open your android phone with 'Google translate', there is any option to point the Camera to the text and it would try to translate it to English. It also works for other languages such Japanese to English or Korean to English or whatever. The translation should contain 1/5 of jokes, but it will leave enough clues for your guessing.
The translation will appear in the screen, it is quite handy.
For the sharp pointer electrode, it is a hard alloy of copper which contains silicate or something, it is more durable than pure copper as those in the connection wire.
Well I figured out everything from the back of it :-)
I bought this welder after watching your video. I just tried it and was having problems. I could not get a solid bond between the ribbon and the battery or between two pieces of ribbon. Used my Dremel to sharpen both electrodes and Bob's your uncle. Works a treat.
Thank You,, nice to know,, I have used 0.12 & 0.15mm ribbon strips and they work well,, I have heard that 0.2mm can be a problem.
Make sure you're not applying too much pressure - you want high resistance through only applying very light pressure for best results. The fact that sharpening the tips worked is pretty good evidence that was the root problem.
@@anticapitalize Sharpening might not have been the issue.
Copper can oxidize a layer you can't see but effect performance. The sharpening could have just removed / cleaned the oxidation and it wasn't the "sharpness" that actually fixed it.
Neat little thing and yeah it only runs about $67 where I live (in Canada). Some of those other $25 ones on Amazon look a bit sketchy. This thing looks nice.
Some of them you need to add your own battery. This one is a complete solution.
@@MyPlayHouse Well, that's even better then, I did not know that. For the price, "with" battery?! Good deal I think.
I ordered a spot welder from Banggood using your affiliate link. Very useful video and tip to be able to replace cells of Makita tool batteries etc.
Hi partasuhari
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Spot welders need a bit of resistance between the two metals to work well. If you wrap the fuse wire around the copper, you make the connection too good, and so the highest resistance point is somewhere else, for example between the probe tip and the fuse wire, resulting in most of the heat being produced at that junction instead. I think trying to spot weld the fuse wire to the copper wire is a bit tricky because to get a high enough resistance, you need to have it touch without wrapping, since both conductors are essentially cylinders. You might try putting one short section of the copper wire on an anvil, and hit it with a hammer to flatten it out a little. That will give you a "line contact" instead of a single point contact.
Hi yeroca
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
Very well done 👍
Thank you! Cheers!
High setting is probably for tin plated copper strip. Copper has lower electrical resistance than nickel but requires more power to spot weld because of this. The reason they use nickel is because it's easier to weld due to the higher electrical resistance.
Hi Atomicskull
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
That second spot welder the banggood one, what you need is a 30amp fuse in the plug and back of the machine and depending on what circuit you are using, i had to swap out the circuit breaker for a 32amp C breaker for high inrush currents.
Yes,, way more then what I need,, this small battery one does the job.
@@MyPlayHouse yea I don't blame you, to be honest the battery spot welder looks better.
Very interesting video. Put heat shrink on the probe handles to insulate them against accidental shorting.
You do not feel it at all,, but the first few time you worry a bit,, and it does not get hot.
So if I didn't insulate it, it won't short me?
Very nice :-D, controlling the duration of the discharge to make it the same every time.
And your probes have to be on the strip before it fires, better control.
Clever little box, i bet they took a while to get it optimised.
Along with the small area probes, control again.
Compared to everything else I have trued,, this is great 👍
When i opened mine i felt nervous about the one side bare terminals being so close to the base metal casing of it so i slipped in a thin piece of plastic to isolate it from the outter casing. I mean its unlikely it would ever touch but it was just one them feelings and these batteries are the violent explode type.
There is a lot of power in the batteries, and they will deliver it very quickly,, so you do not want to short it.
@@MyPlayHouse Thats why i added the plastic to it. just felt like a design oversight they did it that way.
Thank you so much! I'm trying to make my own custom cookie / polymer clay cutters, but unfortunately aluminum can not be soldered and using rivets is not the best either. So I do will take a look at this. I was wondering if I should make my own, but it would cost just as much in parts as this.
I did do a video , where I build my own,, it did not work that well :-/ so I got this one,, and it is much better.
you can solder aluminium with a blow torch and aluminium soldering rods.
It probably is a one trick pony, but it seems to do its trick rather well! Nice little device, really!
At first it seems counter-intuitive that you'd be able to power a spotwelder from such small power sources, but what the spotwelder does is taking the power provided to it over a long time and release it in a millisecond or so. The great advntage of spotwelding is that you don't put a great amount of heat into your parts to achieve the connection after all!
So Bob's your uncle, Pocket-Spotwelder Olé! :oD
Compared to the other two tries,, this was great.
You obviously have no understanding of how this work
Use a magnet to hold your nickel in place
Hi niche 123
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
I bougth a very similar one and found myself having to use the max setting to achieve the best result. The one you have seems to be a nit better. At the end it got the job done and it did not break the bank.
I have also been steeping mine up.
I don't like how the connection for the welding "probes" (don't know what to call it) are surface mounted, especially because they require some force. I think that'll probably be the first thing to break. Maybe it's best to put them in and never take them out again
Yes they are hard to get in,, so I did not take them out. and would probably only do that to replace them.
@@MyPlayHouse I have a similar unit, different layout PCB though, with the same battery setup, I removed the spot weld probe sockets and ran flexible 8 gauge cable straight through the holes in the case and soldered to the board/copper bars, and it welds quite a bit better. Now able to do 0.15mm Pure Nickel welds reasonably on max setting where it did poorly before. Connectors or any added PCB resistance is super important on spot welders. Note: If you do this don't make your leads much longer as longer leads result in higher inductance and the resulting voltage spike during the weld may destroy your MOSFETs
Thanks for the device review n demo. And you channel seems good. Found it by chance thanks to the algorithm gods.

Also friends I know it is best to grind off the remains of nickel tabs from reclaimed batteries for soldering but is it as good for spot welding???

The US Amazon site has all of the specs in english. Theirs is listed as having an aluminum alloy shell. $67. w/ free shipping on 3/23/21 Amazon has a good return policy too. Can you test the output by putting the tips on your tongue?
Well you know the US is only 5% of the world,, and for us outside, returning is not really an option. and the Spot welder is like $20 cheaper from China.
I would not test anything that melts metal together,,,on my tongue.

It should be Li-Po because that's what gives it the high discharge rate needed for the job.

Did you use pure nickel or the roll that came in the box? The box roll was nickel aluminum. I tested it in water. Point is if it's .15 or .2mm nickel it would have alot of good uses...I own one and haven't touched it sense
I have used mine quite a bit.
Hey friends.
Great video.
I have the same spot welder but have had problems using anything thicker than 0-1mm.
I would really like to know what connections are they using from the pens in to the unit. Are they XT150 bullets as I have bought some pairs and plan to extent the cables to 12inch I’m total using 8awg silicone cable. Am I correct in thinking these things above and will it be of service as I doubt the cable they provide which is said to be 12awg and would I get a better welding experience using 8awg at 12inches or longer???
Thank you kindly friends!!! ✌️🙏✌️

I don't know if you care, but it seems like you used a bit high current or camping force. Decrease either of them and the yield strength will be higher.

If I used copper strips instead of nickel would I get a better battery in practice or is it like a meaningless improvement having the better conductivity of the copper. I think it's like 22% for nickel vs 100% conductive for copper, sounds big but is it actually noticeable???
Is this able to spot weld copper strips? someone else had problems.. ?
@@MyPlayHouse I don't know.
Saw this product on bangood a few days ago, was wondering if it is any good... I figured i'd take the chance for the price, it is nice to see it reviewed. My only complain here is that the interface is not the best, but again, it is cheap. But i'd like a slighly more expensive version with perhaps a tiny oled screen and a few buttons for more settings...
It works really well for what I am doing. I am happy with it,, :-) an OLED display,,No surround sound? :-)
@@MyPlayHouse i meant one of those small monochrome oled displays, as on the TS-100 soldering iron, it is 128*32 pixels; super crisp text, low power consumption, and it costs 1-2$ per lcd (i2c interface) from the usual chinese stores :)
It allows to print values on the screen (for the TS100, you can see the celcius (or farenheit) degrees, rather than 4 levels of power), and thus you can have more precise settings, know the settings exactly (here you would print the amperage output, and the pulse duration, for instance... and having those settings may enable you to succeed the spot welding on copper)
Anyway, cheers!
Hello, I like your video thank you I was looking for some thing for my project which is soldering copper wires to break a infrared panel LED lights. Soldering is not my forte, so I think spotwelding could be better.
For spot welding copper, this is not powerful enough. :-/
I've tried this one after some good UA-cam reviews, but I could only get 0.1 mm pure nickel to stick reasonability well. For some more serious battery packs, this is not enough. I've ordered the KWeld from Germany, and that is some much better. Even on low settings you can weld 0.2 very easy. A bit more expensive, but worth the extra $.
I have used 0.12mm and 0.15mm with out any issues, I hear that 0.2mm is the limit for this one.
Did you get that exact device or some replica?
I don't know what I'd use it for but I want one. It doesn't look like it could handle bigger projects with larger pieces that I have in mind but I have so many tools that I've only used once what would hurt having one more?
This putting nickle strips on batteries is what it is very good at.
Helpful video as just about to replace 18650's in my Makita, would this weld the metal cage that holds and connects the batteries, probably a bit thicker than the nickel strips that are shown in your video, many thanks
Thank You! This spot welder is best up to 0,2mm nickel,, it might work,, but it would be a long shout.
Thanks bud
You are most welcome :-)
What are your thoughts on whether or not this thing could be used for simple tack welding, such as for tacking a nut to a washer or metal frame just to hold it in place long enough for a bolt to be threaded on? I realize the tack might be very small, but perhaps several spot tacks around the perimeter (of the bolt or washer) for example might be enough for this purpose? Also, how about use as a "lock-tite" equivalent to hold a nut onto a bolt (so it doesn't unthread easily)? Just wondering if anyone has ever tried this with any success.
This is for very thin matrial,,0.1-0.15mm and works very well with these battery strips,, not much more than that. I was told that it has problems with 0,2mm.
@@MyPlayHouse Thanks, just the same I purchased one and will give it a try on my proposed application and let you know how it turns out. Back to you later
Can the probe wires be replaced with larger gauge wire in silicon test casing without hurting the welders performance? Then I could mount the welder on my lab bench.
It can become a little better,, but I am not sure it want, just be better to get a bigger one.
Will this spot welder connect small metal pieces? I build custom die cast cars (hot wheels size) and want to build small roof racks to fit on them. What do you think?
I have not tried,, it does up to about 0.2mm with the batteries here.
have you tried the 0.15 and 0.2mm sheet thickness of zinc?This device is great for DIY work
That is nice to know,, think the stuff I use is 0.12 and 0.15. Thank You!

LOL :) Thanks (to you too Danilo) again, cheers !
I never new that about the cell phone and Google app awesome
Wouldn't it be nice if you could buy cells with little tabs on the ends so they could be entirely soldered with no chance of damaging the cell.
Nice little machine though!
Yes,, :-) that said,, they are holing up surprisingly well.
I bought the $24 dollar green one that doesn't have the battery. Made a 3s battery for it. It works perfectly at level 18. Don't buy the one made to run off capacitors. They blow up.
I liked this one as workers so well right out of the box.
When I received my spot welder, the battery measured about 0.5 volt. It should be a value of 3 volts or more to be on the safe side.
I put it on the charger and after charging very slowly for about an hour(0.1-0.15A).
Then when it reached about 3 volts it was charging for a couple of hours on 1.1 amps max.
Eventually it reached 4.19volts and was ready to use.
I grinded and cleaned the contacts on a 18650 lion battery and a AA nimh battery.
Tried different output levels (1 red light till 4 red lights).
The performance was very poor. Even with the included 0.1mm nickel plated strips.
The nickel strips do not stick well to the battery. I can easily remove them so it is not a good connection.
Probably it is caused because of a poor battery. Maybe with a good battery it can weld the thinnests 0.1mm strips but definitely not more than that.
There are more people receiving this spot welder with an almost empty battery. Maybe the included self discharge circuit is faulty.
I will not recommend this spot welder to anyone because it probably only works well with a new battery. If the battery ages it will have the same problems as I have.
I did as you saw. not have this problem.
Nice review. I'm a bit concerned though that it could not melt copper. Although you may need higher melting electrodes but 600A should melt copper depending on the on time.
Copper is really good at leading both current and heat,, this tiny spot welder,, is to small,, and nikkle strips of about 0,2mm is the upper limit.
It doesn't work on copper because copper is too good of a conductor. To generate the heat you need some resistance: P=Isqr*R. The nickel strip will melt but not the copper, so no weld.

Sorry I must halve missed it what size straps are you using. I have the same welder but mine cannot make decent weld.
Up to about 0.2mm mine can do okay.
I am VERY IMPRESSED!!! I agree with you on the build quality looking VERY GOOD... ESPECIALLY for only about $50 !!! WOW!!! But like I was stressing in the top pinned comment PLEASE periodically open it up and check THE BATTERIES to see if they ever start expanding or "pillowing" - cheap Chinese batteries are NOTORIOUS for 'exploding' and really what can you do if it burns your house down? Who could you sue for damages? Do you even know who sold it to you? Are you sure they have closed that company down and started it back up under a new name?>? This happens A LOT with the CHEAP Chinese products.... So EVEN THOUGH it looks like it was build VERY WELL, there is just NO WAY to know if that battery has such good quality...
So the ONLY thing you can do to protect yourself if to regularly check them...
I don't think they go bad just by sitting around not being used (especially since it automatically drains to 50% after a few days without use) but that is a CLUE that they may already know the batteries aren't the highest quality - I have NEVER heard of a company automatically drain their batteries like that... and so that is a RED FLAG for me.. I would keep it AWAY FROM other things that could burn, and in an area that would let it spread to the rest of belongs and house....
The MORE you USE and RECHARGE it, the more risk you have - so PLEASE CHECK THOSE BATTERIES REGULARLY!!!!! :D
- - - Oh and THANK YOU for find and sharing this!!!! Having a small spot welder came across my mind while building not too long ago, but I managed without it. So if I had this it would have been VERY HELPFUL.... so I think I will pick one up and put it to use!! THANK YOU!!! :D

How about eye protection? Does it weld spots into your retinas? Are seeing stars even when not looking into the night sky?
I have not seen that need.
@@MyPlayHouse Thank You. I did a little research. My understanding is that spot welders are relatively safe compared to arc welders because they only heat the metal. The arc of an arc welder generates harmful radiation which is not present in spot welding. Dark tinted glasses are recommended by some for spot welding however.
Nice video, what other use is there for this welder apart from sticking batteries together, can you solder or join other metals together like making fitting for model boats perhaps? Thanks.
Sorry I do not know of other uses.
That looks like it could be adapted to power quite a few things?
I would probably just get a power bank instead.
Used your link, and just bought one 😃 good enough for what I’ll need it for, and I can easily replace those leads if needed. The auto-discharge feature sold me on it. 😎
Thank You,, I can see that it is very popular! :-)
Did same and purchased one locally. I had to open it and screw the battery on the main board but otherwise all good :)
auto discharge is a pain in the ass. prevent you from getting good pressure down before it fires. especially with thicker gauge nickel strip for high power applications.
Nice device after inprovements are done :)
Improvement #1 make new longer cables with more beef and insultate to the very tip.

Hi Jan Seidel

To your point 2) I glued a Velcro pad on the box and on my silicone work pad. Holds perfectly.
longer cables mean more resistance, means higher powerloss and current draw from battery and hotter components and shorter life span
Maybe make a weighted base for it, would keep it from falling over and prevent scratches, etc..

I just purchase the exact same one and even after watching your video at least ten times and ensuring the settings are correct, it doesn't produce enough power to spot weld the strip on the batteries.

@@MyPlayHouse ok, thank you, I really appreciate your reply, answering my question.
For the average person that will be spot welding 18650 batteries off and on when the need arises for small projects, its works well and very reasonably priced, and btw... theres a youtuber by the name "Sanchai" that reviewed this very same spot welder, tested by welding two peices of nickle strips together, from the lowest to the highest setting, it will not weld .2mm hardly at all, so for best results, use .1mm or perhaps .15mm the most.
Hi Bige4u
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
As your helpful video shows the spot welder quickly and easily creates an adequate mechanical connection with little danger of damaging the battery due to overheating. However the electrical connection may not be as good as soldering. Spot welding creates a tiny contact area compared to soldering. Presumably this would create additional resistance, although perhaps not enough to matter.
Hi David

i would have prefered a 18650 as internal battery , at least u can replace it quickly and easly if needed , cos i dont think that battery in there would be easy to find .
These packs can output a very high Amps, where 18650 is more for longer discharge..

Sorry I really do not know :-/
Hello 👋 I am going to buy a wee spot welder just like yours, you've had yours a year now how is it working now?
Last I used it it was fine,,, I do not spot weld all the time :-)
If you store it for a long time make Shure you recharge it every once and a while or it will drain the battery to low to recharge .
Okay,, I will do that,,, been awhile since I charged mine last.
I just ordered one. I see there is now a pdf manual in English.
uhh that is an improvement :-)
Only thing I don't like is the welding leads.
I'd prefer to have a screw terminal/clamp to attach leads so I can make my own out of a piece of 10 gauge stranded wire with a copper wire form a length of romex as a tip.
That way I can have whatever length I need, and have different shaped tips.
Would be nice if the tips, was replaceable.
@@MyPlayHouse i think I'm going to just avoid welding entirely.
Nickel isn't really much good for high current battery packs.
My pouch cells will be mechanically connected with threaded aluminum rod to avoid corrosion.
For my 18650 pack I'm going to order some high conductivity silver based adhesive to bond coppet bus bars.
With the 18650's I can pull 30 amps per cell, and thats just too much for nickel.
And the pouch cells are up to 200 amp continuous, 400 amp peak.
I'm a newbie about spot welders. So it just shorts the battery every time it triggers? It is not using a capacitor?
Yes,, kind of,, but for a very short time.
Thanks for this showcase... $70 Bucks and it works :D
It can be found a little cheaper,, $55 is a good prices.
Good explanation!!! I'm wondering, will it weld sterling silver..? Could it be used in making jewelry?
It is pretty inexpensive,, so you might just want to try,
I hope to use .2mm pure nickel strip to connect my 21700 cells. I think that would require this one's larger brother, which is yet to be?
I am using 0.15,, that works fine.
@@MyPlayHouse Are you on full power?
At 12:45 you can see an arc flash from the electrodes back toward your body. Did you feel it ?
No I did feel a thing, not sure it got all the way to me.
Maybe smear a little Solder Paste on the joint before welding?
The solder does not take nice to spot welding,, it kind of explotes... tiny of cause.

I'd add heat shrink to the probes, so that only the tips are exposed. Too easy for bare copper rods to touch accidentally.
