Hi everyone!
In this video I decided to show you have I made this simple and cheap spot welder which is a highly useful tool for a DIY'er that can be used in many different projects for creating rechargeable battery packs! Nowadays, lithium batteries are widely using in the electronic products, rechargeable batteries, electric vehicles, balance vehicles, aircraft models, ship models, electronic tools and so on. I am using a microwave oven transformer that I have salvaged a while ago. I also compare my DIY spot welder to a $200+ Mini Intelligent DIY Spot Welder OLED Automatic&Manual Switching Lithium Battery Power Battery Pack Welding Machine SQ-SW1.
Hope you give this project a try! ✌️

@colinellicott9737 Год назад

Nice. A few comments - high V solder instead of crimp connections can be a failure point, as can one thin layer of heat-shrink as a strain relief, then the case should be grounded metal for numerous safety & emissions reasons, and case bolts being accessible from the outside while exposed inside to wiring is another failure point, then is the power inlet appropriately fused? One minor point is that exposed electrical components can be damaged from ESD so protecting them would eliminate another failure point. Are the high V windings thermally fused? High voltage cables should also be double insulated, especially if subject to wear, etc. Stay safe out there ; )

@Michel-Artois Год назад

You don't have any high Voltage cable on the secondary coils (here between 1,7 and 3,5V, variable with the rounds you choose, approximatively 1V per round) but simply high Amperage cable with very low voltage..... which is absolutely not dangerous . With such a low voltage the current cannot run through the skin of your fingers if you hold both electrodes separate in the same hand and switch on ( please no direct contact between electrodes !)...but most of people would not try to do this , when they see the welding result.... It's exactly the same as if you hold both electrodes of a 12V car battery with 650 amps/output with your hands...nothing happens....and if you put a copper wire it burns very fast . But I agree that a double insulation would be safer, simply to avoid a ground short between cable and sharp angles of the transfo by abrasion. Low voltage (till 40/50V max), even with high amps, is not dangerous, except with a direct metallic connection like here for welding. In this case danger comes not from current but from heat . High voltage with low amperage is very dangerous : current runs through the skin and blocks quickly the heart (tetanisation)..... But a defibrillator uses this current with very short pulse (and contraction) to start the heart again. High voltage with high amperage...Heart locks down and you "burn" immediately.

So 10ms with the Sequre SQ-SW1, but I couldn't make out what you set yours to at 14:22. Yours produced welds as good as I see on most battery component tabs. But my tabs are 0.3x6mm and that is why I'm looking for examples of what other folk are doing to for inspiration but not seen anyone spot 0.3mm

@DonnyTerek 2 года назад

Thank you! Glad to see you found my video helpful. It was set to 06-80 at that time. These may differ from build to build due to different wound cables, thickness etc. Haven't had a chance to weld 0.3 nickel myself yet. I double or triple stack thinner pieces if needed. Hold just fine.

@johnlees3281 Год назад

Made one like this, I found I am getting factory like welds with no indents on battery from pressing too hard or burn marks by setting my current: @ 70 and time: @ 5 or 6 milliseconds. No need to press the strip down too much, just enough to hold it in place is enough. I did not like the springs on the welding pen as they require too much pressure to trigger the microswitch so got a foot pedal instead. Thanks Donny.

using copper/tungsten tips adds that last touch, those tips are much harder than copper alone and the high current doesnt bother the tungsten at all.you can feel the difference in the weld.

@virinom Год назад

Removing thick isolation and replacing it with thinner heatshrink tube is really nice idea. Just to be safe I'd have use 2 layers of heatshrink, for sharp edges on the core.

@Mayhem2019 Год назад

It's actually a horrible and dangerous idea, when you do that you have basically killed the rating on said wire and even 2 layers of heat shrink will never give it near as good as the protection as the original sheathing, not to mention the wire is no longer UL listed which might seem like a small thing and just being anal about but in the event of a fire/accident these are the first thing that insurance companies look for and can totally invalidate any claim, but of course in said event human lives are the most important thing. Overall though the rest of the project was very well done.

Thanks! Even with one layer of heatshrink tube I had a hard time getting the cable 4 times around the transformer.

@Mayhem2019 Год назад

@Michel-Artois Год назад

Hi Donny, very nice building for your DIY spotwelder.! But I must say I built one and compared with my not DIY other one. The problem with the board of the DIY is that we can only select power (amps) and welding time , but all of this only for ONE continuous pulse. The other one adds a choice for several pulses (1 to 6), each one 20millisec,, so it's not necessary to have a precise regulation of the values, the welding is always good and first of all the nickel stripe cannot burn. That happens sometimes with the DIY : for a good welding I am always at the burning limit (you too on the video, with brown circles around the weld) ; if not ,ther's no welding. It's because ther's only one high impulse. With 3 pulses we don't need so much power . I don't know if we could find now such a board for the DIY. It would be the Best! i add that with the DIY I am not always sure of weld quality, sometimes very good, sometimes not, so for high discharge battery (like for power drill or cordless vacuum) I don't use the DIY....and for a motorcycle battery I always solder (more than 100amps for starting) But for use of "the good one" I need a 40A protection, so I have a special switch in the garage. The DIY can be connected on every switch in the house. Friendly, Michel.

@DonnyTerek Год назад

Hello, thank you for the informative comment. I believe I saw a few different DIY boards for spot welders that can produce several pulses but haven't tested any of them myself yet. I may do that for my other spot welder build and compare it to this one. But I do agree that it is sometimes difficult to get a proper weld using the DIY welder.

@Michel-Artois Год назад

@@DonnyTerek I think it's because we must always be at the burning limit with the DIY, and sometimes the electrodes are as "glued" on the nickel stripe . So after ripping them from the stripe they are dirty with some nickel glued on the weld point, and contact quality is no more good . So it's necessary to brush very often the points with sandpaper if we use the DIY , always perfectly clean.....but take care that both points must have exactly the same contact surface (half-round) . If not, we have more intensity on the thinnest one, that gives spark and sometimes a hole in the stripe.

@DonnyTerek Год назад

@@Michel-Artois Yes, I have noticed that too but not only with DIY welders, same goes with the SQ-SW1 that is shown in the video. After a few minutes of welding the electrodes start to stick to the surface so I lightly sand them with a soft sanding sponge.

@adrianph9564 Год назад

Just a quick question if I may, I can understand the timer section of the controller selecting how many cycles of mains is being switched into the large transformer, but the current side of the controller is only switching the primary side, which I would imagine you do not want to restrict. So do you actually use the current limit function of the controller?

The copper part of 25mm2 cables is 6.8mm. I think this is not enough. When you peel off the outer shell and fold the cable in half, the copper part becomes 13.6 mm. Do you think this is enough?

@DonnyTerek Год назад

Thanks! Doing a bit of research on DIY spot welders, I found that the 35mm squared copper cable is best for a job like this to get as many (4 in this case) windings of cable around the transformer for higher current output.

@francoisguyot9770 Год назад

@@daltonndickeyy3545 You're "spot" on. the larger the copper conductor the larger current it can handle without melting down the insuation only after 5 welds.. Also less loops means less voltage whch prevents arcing and more currrent to get to 200A. Asa Shemon says, the pulse witdth will determine the amount of power delivered. Since we want the shorter possible time because it burns through the nickel strip, we sure want to deliver the maximum current through that transformer.

Can the transformer be used for soldering 18650 batteries without that control module?

@DonnyTerek 2 года назад

Most definitely not.

@aluzexp Год назад

Great video! can you use it on thicker nickel strips (0.2mm)? Thanks.

@DonnyTerek Год назад

Thank you! I haven't tested that myself actually. Though I have read that 0.15mm is the limit for Sequre welder.

@tadracket448 2 года назад

Какое SQ кабеля (диаметр медной части)?Достаточно ли 2м?Что значит заморачиваться с заменой покрытия? Какие два модуля вы используете?Можете ли вы купить его на амазоне?Я тоже сделал его,но даже если лента для подключения батареи станет красной,он будет приклеен как у вас.Нет,я использую только трансформатор,но как сделать красивую и крепкую связь?

@tarekabdo7392 2 года назад

Good work. Why you use heat shrink with wire instead of the wire cover

@DonnyTerek 2 года назад

Thanks! The heat shrink is thinner than the sleeve of the cable therefore it is easier to wind it through the transformer.

For what reason do you use 6AWG cable for the pen? Wouldn’t it be better to use the same cable as the transformer to avoid losing amperage?

@DonnyTerek 4 месяца назад

The 6AWG cables are of the SQ-SW1 spot welder that are included, not my DIY build.

@edvinassarulis7526 2 года назад

Im consufed with whis welder. I got same, just Tips from solid Square copper and made it round ends. Tried settings but mostly works 10-12 pulse and ~95 current. Below that doesnt weld properly. But with that settings nickel heats and changes color around. 2awg 3turns secondary winding. Where is problem?

@DonnyTerek 2 года назад

Hi! Try making 4 turns on the secondary. That is why I removed the original cable protection and replaced it with thinner heat shrink tubing to allow me make 4 turns on the secondary.

@edvinassarulis7526 2 года назад

@@DonnyTerek issue was 0.2 nickel. Yesterday tried 0.1, weld perfect. Ordered 0.15 to try. Also in general its 3.5 turn, so not sure how actually to count, 3 or 4.

Хватит ли кабеля (диаметр медной части) 2м, в чем смысл замены покрытия?

Hi there, what is the reason for removing the magnetic shunt pieces in the transformer? 1:05

@DonnyTerek 11 месяцев назад

Hi, sorry for the late reply. The shunt pieces are not needed for this purpose since they limit the current to the secondary coil.

@krisea3807 2 года назад

Thank you for such a wonderful video. When you touch the electrode while spot welding, will it shock?

@DonnyTerek 2 года назад

Thank you! No, it is safe to touch since the voltage is very low (3-4 V)

Counter top appliances have welded wire conndectons instead of soldered connections due to heat. Can these small welders repair these types of connections.

Depends on the thickness of the connection, I guess. Most the spot welder can do is 0.2mm.

@DonnyTerek 2 года назад

Hi! Sorry for a late reply. This spot welder that I have made is practically the same as I made before, using almost the same components. The main difference is that I used 35 squared mm cable for the windings to get 4 tight windings and used longer cables for the welder handle to make it more comfortable to weld. Truly means a lot that I inspired / helped you on the road to build your own e-bike. Would love to go for a ride once you finish yours, haha! Thanks again and best of luck. Keep me updated if there's anything else I can help you with.

Hello Donny, great video, may i have one question, which type AC circuit breaker need this MOT cheap spot welder from Aliexpress? 16Amps or 25amps or more? I can have max. 25a in my flat house. Thank you in advance. Have a nice day. Greetings from Slovakia :)

@DonnyTerek 2 года назад

Hello Michael, thank you! The spot welder produces around 3-400 Amps of current at only 3-4 Volts. Considering you are using 220V AC, you won't exceed 8 Amps on the circuit.

@michalbosko 2 года назад

That's perfect, thank you very much. I have asked because my first spot welder is JST-ISS, and this device doesn't have any zero crossing relay and therefore I'm not able to do strong welds. So I'm going to buy this one in your video. Thank you one more time ;)
