Mate, your homemade spot welder is 100x better than the cheap chinese $150 unit on eBay!! Great job =]

Works great. Not one word on the welder. .This video is totally useless. If I want to watch somebody spot weld batteries I can go to my local Batteries Pus store. If you made this welder, give us a look at the welder, not just a demo of it working.

Yeah, now all we need to do is figure out what the hell kinda machine that was at the beginning, reverse engineer his contact and trigger mechanism based off a tight shot of his thumbs and we're good to go! This video makes it super easy to make one for ourselves!

Nice! Can you share how you made it?

Thanks for the video, I bought the 60000 mah lithuim 18650 batteries for my own home built tesla wall and the spot welding is the way to go. I also have some electric bicycle kits this is the way to go as well

nice job!

What kind of tabs did you use?

Where did you get the protection for the cells?

Nice-looking welds, ejssja6911! Some specs, please? What output voltage did you use, and what's the pulse duration? And is that just 12 AWG copper wire that you're using for the tips? And what's your favorite source for for the tabs/strips?

Whats the current ? How many amps to make so nice and strong spots ?

I built an arduino controlled controlled one and I'm just blowing holes through the batteries. I was wondering how long you activate your welder for.

+Michael Schalk I have the same problem. I found pulsing it for .5-1sec works ok. My transformer has 3 turns of 4awg welding lead and is putting out 3v 1000a. I'm using a foot pedal from ebay that works great. I've got maybe $20 in my build.

Is 12v 15a enough to make it?

cable several centimeters thickness ? how many meters in length ?

Specs please.

thats mint man

dude .. just use a capacitor ... 33 000 uF and a 12 volt adaptor. same shit only simpler

@thingsdemystified

zloben9000 That's a good idea. That will also ensure that you won't overheat the battery. How did you arrive at that capacitance? I assume it depends on how thick the strips are.

zloben9000 I happen to have four 250,000 uF caps laying around. I'm going to wire them in series and charge them up to around 48V to see what happens. If that doesn't work, I'll get a couple of those 2,000,000 uF car audio caps and wire them in series.

@valveman12

ThingsDemystified Why would you wire them in series? You will loose capacity. 4 250,000uF Caps wired in series will drop you capacity to 0.063F. Sure you can get to 48V but very low capacity. Maybe wire them in parallel to increase capacity to 1F. Yes you may only get 12V but lots of capacity.

@thingsdemystified

valveman12 I will try it to see. I don't think wiring them in parallel will produce enough voltage to make it hot enough. Capacity isn't the issue. We'll see.

what did you use for the electrodes? i think that may be my problem!!

Esta bonito ese proyecto pero enseñenlo cómo hacerlo.

bro plz tell me how you made that welder

so no instructions?

I have absolutely had it with people posting "how-to" videos that have no audio and give little or no instructions for how to do something! I'm trying to actually learn something and I have to waste time weeding through all these videos like this one! If someone wants to post a video just for shits and giggles then that's fine but it should be somehow marked so they can be bypassed by people who are actually trying to get some useful info.

do it yourself but most people don't have this equipment

very kool..

Battery spot welding machine is mainly used for 18650 cylinder call pack welding, it can weld Nickel tab thickness from 0.02-0.2 mm with good welding effect. The pneumatic model is with smaller volume and weight, easy for international shipping. click on www.tobmachine.com/18650-Battery-Spot-Welding-Machine_p766.html, view more.

how much? weight and size?

Fa tori Made?

just curious is video supposed to educational, entertaining, informal or just pointless?

im pushing 1000AMPS and have failed my every attempt, even with the battery tabs getting red hot and putting massive pressure! i think i got it most of the time then i look closer and realize that its just the melted plastic holding it on top!! :( why cant i do this?!?!?

@paintballthieupwns

+Brian B. it's not so much the amps but the total energy discharged in that faction of a second. Think of it like a capacitor discharging. During the faction of a second a large cap discharges the amps are probably well above 1000 for the smallest amount of time. This forces the current not only to path through the electrode to the tab but also jump down to the battery and then back up through the tab then back to the other electrode. Either his setup has a cap or a bank of caps in it or has a monster supply capable of massive instant discharge rates.

what fuck! no instructions? that is part of youtube agreement. share the damn thing

wtf .... so how its made ?

I made a battery tab spot welder with the same type of microwave transformer. Output 2.33v ac 1 Awg wire for the secondary. Two welding rod electrodes but it won't go throught the metal and weld the strip to the battery. it just weld the nickel strip and the electrodes together. I tried to use the momentry switch to act as a timer, but it still not success. What's wrong with it?

Andreas Christodoulou your problem is the amp rating use car battery terminal directly to the copper electrodes... The microwave thing put lots of amp to the secondary enough to get it melted to point of burned off... Try car battery or any other battery with higher amp. batteries have enough amp for your work on your li ion battery

I learned nothing except that you may be mute.

you call this home made?

hopeless a bit show off

does not understand how to

n’apporte rien

thanks for wasting 2 minutes of my life!

Thumbs down for the useless vid. It's not a homemade welder.
