Brilliant review. I bought this spot welder in large measure because of you to repair my 52v ebike battery with 21700 Li-Ion cells. Thank you very much sir. PS. for those interested, my spot welder arrived with dead battery as well...or very low. Presume this is for preserving battery life and shipping safety.
Hi Chuck, very interesting video with comparaison of different gears! For occasional use it's a very useful and pleasant device! I think the only utility of the delay is to preserve the mosfets and the battery against too quick repeated weldings which are not good for such a little device. Please be careful with your file on the positive pole of the cell : the external circle is negative , and if you are in a hurry and scratch both together you get a short immediately. Friendly...
I don't have any 0.2mm nickel strip, so I couldn't test it with that. It does 0.15 fairly easily, so my gut feeling is that it would do 0.2, but no thicker.
I got the same one but didn't realize its not recommended for .2 nickel strip im gonna buy some. 15 nickel and see if that works. I also checked the nickel that they send with spot welder its not pure nickel I also hear the fake stuff is easier to spot weld allegedly.
it seemed to work fine with the 1.5 stuff I have. Whether it's pure nickel or not is anyone's guess. It's advertised as pure nickel, but I have no way to confirm that.
@@3rdpig it's really super easy to confirm. Make a glass of salty water. Nick a piece of strop and leave it overnight. If there is corrosion in the nick it's steel, nickel does not corrode. The other way is even easier.Take ur Dremel with cut off wheel. When cutting, if it thought sparks, it steel. Pure nickel does not spark. I have a couple of place tat sell true nickel,. 1, .12, .15, .2, .25 99.6%
By Ali or others it's most of all fake nickel, but it works without issue for common use. Only if you really need high amps drain (more than 30A) pure nickel is better. We must also consider that a spotwelder gives very small contact points on the cell, different from a real tin soldering, so for a maximal contact and easy drain we need a lot of spotweldings with fake nickel.
I ordered one from Amazon the battery showed dead tried to charge it but wouldn’t charge, ordered another one and same thing dead on arrival. I will never order anything from Amazon with batteries again they must sit on the shelf to long.
Was yours fulfilled by Amazon or a third party? I've never had this particular problem, most stuff I order from Amazon with rechargeable batteries usually have some charge in them on arrival. I just ordered 3 Neewer batteries for my Osmo Action camera and a rechargeable wireless mic of some unknown (Chinese) origin and everything came partially charged. I hope you didn't have any problem returning them.
@@3rdpig thanks for commenting, when i ordered it said fulfilled by Amazon I told Amazon I was going to keep ordering it until one comes in working even if I had to order ten of them lol. Just a week ago I ordered an electric scooter battery was also dead tried to revive it but it would only charge to 26v so I assumed I had some bad cells. It would be nice if they could test them before shipping them out.
Did you ever figure out how to fix this? The manual says that if it's over-discharged, "contact customer service for the wake up method", but I can't find any information on who customer service even is to contact!
You are correct Chuck, the learning curve of this unit is much easier, this is definitely the better unit!
It's better and I think it's better thought out. Of course it's newer too.

Cool device. I got mine today. It’s a different type without display, but the same brand. Thank you for the demo.
Very good explanation on how this great little spot welder works
Thanks

Nice review Chuck! I’m looking for an affordable welder for small 18650 projects. This Riiai looked good. Can you update after a few months of use?
Thanks for the comprehensive review.
That's a nice piece of kit, very easy to use.
It really surprised me how easy it worked right out of the box.
lmao all the metal objects your using to hold the 18650,s upright with . good review and thanks for sharing
I guess I failed to mention 2 points.
1. The batteries were all stone dead.
2. I'm an idiot and you should never do what I do.
Thanks for watching!
What's the tldr? Feasable for 0.2mm Nickel?
I don't have any 0.2mm nickel strip, so I couldn't test it with that. It does 0.15 fairly easily, so my gut feeling is that it would do 0.2, but no thicker.
Hi Chuck, would this be safe for spot weld TPMS' battery?
I'm not an expert on TPMS batteries, but I've spot welded coin sized rechargeable batteries with it, so I would think it should be fine.
@@3rdpig Thank you for replying back.
Hope you & your family a Happy New Year!

I confirmed it by putting a small piece after scuffing it up a little into some water with salt and waiting 24 hours
