In this video we received a fix from VEVOR, a bit unexpected at the least 
Авто/Мото
I bought a VEVOR 30 litre ultrasonic cleaner which failed within two days. The fuse holder melted and two circuit boards showed signs of overheating. They advertise a 30 day no hassle return policy and after a number of emails and requests for photos, they sent two circuit boards which solved the problem. However, one board showed signs of corrosion as it appeared as though it was stored in a very damp environment. They also refunded about 1/3 of the original cost for the bother. So far, the machine is still working. I'm hesitant to buy anything of any cost or complexity from them. Cheers from Eastern Canada! 🇨🇦
Yep, indeed ... tools at half the cost ( as they claim) but also half the quality. I was asked by them ( after this failure of the vevor stud welder) if I wanted to test their products and announce it in my video's... whereby I would get the tools for free and 5% on the sales... I refused ... I am to direct and honest to spoil my channel with tools that are low quality. And will certainly not recommend something to subscribers or viewers that I not stand behind... Thanks for the comments
@@D3Sshooter Steve, i have heard that offer elsewhere on youtube. VEVOR seems unafraid of criticism of their products. It reminds me of the saying, ''there is no such thing as bad publicity''.
@@D3Sshooterbetter have a good tool that you can by used, than this low quality product.
With this low quality product, you will do bad work, spend your time to repair it, ...
That's unfortunate that they are sponsorised review that don't tell the truth on real product quality (or they send "special" good device to tester).
Excellent follow up video..I admire your fairness that you actually gave the manufacturers the benefit of the doubt. The machine seems to perform better but it still looks like a prop from a 1950s Sci fi film..Thanks for uploading.
Thanks and indeed a SCIFI prop - so funny
Such a sophisticated and knowledgeable man using Mac OS, we all have our flaws folks
hahaha, it could be worse - Windows- the only windows I allow in the house are those in the walls - lol
@@D3Sshooter Couldn't agree more, you struck me as a Debian guy. However you do like your photography etc. so apple makes sense in that regard
@@chrismcgowan5180 its out of laziness Chris... but I do like the Debian Linux Release from back then... when to all of that over the years , even Solaris.... lol
Steve - Thanks for the follow up video and well done in your usual fashion. I just checked the Vevor site for this stud welder and there is nothing that says what size triac is used for the gun, only that is "800 watts" capacity. I know from watching other videos of Chinese manufactured electronic items, their power measurements are suspect and can be off by as much as 50% from stated to actual. Glad to see it is welding at capacity now, but this is the type of item I may decide to pay the extra money for a US or European manufactured gun, knowing there is far more likelihood the gun will work as stated.
I would say,if you plan yo use a tool like this... don't take any changes and buy a good tool.. This Vevor business is specked with poor material
Great video, really interesting, thank you! And thank you for a honest, genuine youtube review - something very rare these days....
Glad you enjoyed it!
Hi Steve,
the little tuning worked great. Well filmed and presented😊👍
Glad you enjoyed it
There’s an old saying; “You can’t make a silk purse from a sow’s ear.” Seems appropriate here.
indeed
I just tack the washers and studs on with a blob of mig weld - much better than that chinese takeaway. Just knock the mig off with a slitting disc and a light file or grind to smooth off afterwards - job done.
good point , indeed
In the video of you welding the studs to your fender ----- I thought that weld was very weak ----- With the slide hammer ---- they just popped off ----- I think VEVOR should send out a new replacement with the -- Update -- in it ---- and not have customer make the modifications themselves ----- as for the -- Plastic Body -- should be made so it will with stand an impact --- and not crack or break ----- Would of liked to seen how well after new board installed ---that the studs stay attached to the metal with your sliding hammer ---- hopefully long enough for several pulls before pulling away from the metal ------ Glad VEVOR worked with you and got the problem solved and yes --- that was a quick turn-a-round ------ Thank you for sharing this with us and what to look for ------ Hope you have a Good week ------ Rodney
Thanks Rodney.... (Kortrijk ?)
It would be interesting to see the power of the transformer in the short circuit test, then there would be no more doubts. The 80A triac only guarantees a higher peak in inrush current... but since the trigger is timed, it does not reflect the real power of the transformer, which is probably why they didn't put the heatsink on the component. As for me, this gadget is a cheap clone of a machine manufactured probably in US, Europe or Japan, for a change. good work with the car, it's always a pleasure to watch your videos, greetings from Portugal.
It does indeed only allow a short duration of switching power, which in this case is higher then with the 40A Triac. However IMO design days ( electronics) we always used heatsinks for any power mosfet... Pro-longed use might cause heat damage to the junctions and substrate. In each case, it works good enough for now. Thanks for the comments as always
Electronic engineer in the past, that would make a great video going back over your past career.
I still aim one, but now more on networking and cloud access... but , yes I have some stuff from the past
Nice to see the follow up video. Real question is will it pull dents out. Careful, you’ll be a product tester.
Thanks for the tip!
Steve, Thanks for doing a follow up video. TBH I think they should have sent a new gun and returned the old one. I agree it should be someone who is qualified not a layman.
This is obviously a common issue with some of there older stock but they should have been recalled if they're faulty in my book. Thanks for the warning. Cheers Dave
Its my pleasure Dave, and yes they should have.... but that seems the way they handle things
While I understand basic electrics, I know very little about semi-conductors etc.
However, if an 80A triac is going to have any sort of useful duty cycle, surely the cables from the triac to the electrodes need to be much larger than what appears to be around 2.5 mm sq cables in this woeful machine. (possibly why they try to get away with a 40A triac)
Also, I would be tempted to put an insulating sleeve on the central electrode to avoid shorting to the external electrode when pressed down. In fact a good thick sleeve might help to stabilise it a bit better.
calm down friend! the machine will not consume 80A, the triac will only allow a greater peak of current when you press the trigger, we are talking about microseconds (inrush current), it will not burn your 2.5mm cables! You get these peaks when you turn on your fridge or your water pump... however your cables are also thin!
Indeed, good answer - thanks
See answer below, all it means i can switch more current ... not that it 80 amps ... my fuses at 220V are only 16 Amps...
They should have shipped you your money back too!
yep, but they don't .. As one stated , all they care is sales..
👍
The stud welder you brought was on the lower end of there range I wonder what the results would be with there higher power 6000VA stud welder 🤔
who knows, but no more dealings with vevor for me
No heat sink provided on the new version that is odd, if you can source that triac online you could upgrade your original one as a spare.
Not as easy as that, since the firmware will have been updated to provide extra power(longer duration), the triac has been upgraded to handle said extra power.
Yes indeed, and only 15 dollars/ euro for the TRIAC
👍👍👍👍👍
I'm surprised that you're having an issue with this company. I've been seeing a lot of their products recently on a few different you tube channels. Q
Well, they have cheap stuff and it does not work at all in some cases ... Like the proof I have . At least they shipped a new and more powerful motherboard.. But that should not happen. In each case do not buy the tool if it does not have the improved power TRIAC in it..
if you see a tool on 4+ youtube channels in a short timeframe it's product placements.
just getting the tool for free counts and a lot of channels will do nice with them especially if they are trying to get into the game of getting more free stuff, the way the game works is that if you crap on stuff the pr companies handling the placements will mark you as someone who doesn't play the game nice. this is also why some channels have the best ebike of the year every month, never talk about the ebikes legalities going over the power limits etc (and on channels which normally do no ebike reviews at all).
more established channels tend to be more careful when accepting the deals. and to reiterate most of the time no money changes hands at that level and they'll say something like that they weren't paid for the review, it's their honest opinion etc standard text, but just getting the device makes it a product placement legally in eu and usa - even if it's just for a loan - but the real psychological trap for the channel owner is that if they 'blow it' when doing the review they will not get more '''free''' stuff.
edit: the stuff might even be good of course. you couldn't know it from such reviews tho
Check out what Vevor exactly is: a Chinese company that sells Chinese stuff for the DIY guys among us. Do not expect high quality or good after-sales policy.
indeed,
I think with Vevor products it helps when you have a YT channel and make videos about their products in order to get proper help from them. They (Vevor) give you a hard time in dealing with them.
That seemed to be the case... they were very fast in responding and even offered free products for me to test .... I said " No Thanks"..... see below as an extract from a mail from them yesterday:
Hi, Steve
As I've said before, we don't make any claims about video content and we respect the way you test the products.
And you can test the product before you make the video. If the product's quality performance is not good, we can give up the review.
If it still doesn't work for you, hope we will have the chance to work together in the future!
Best,
Carol

Hi Carol,
After some careful consideration, I decided not to do it.
Main reason is time and most of all, I don’t want to spoil my channel as an in-parcel none commercial channel.
Thanks for the conversations, and sorry for the time you might have waisted on me.
Kind regards , Steve
Nice job, but as you say, unless you complained, the original unit was no good. They obviously know of the fault
Thanks and indeed, one would expect that a normal business would recall the sold devices and replace them with a corrected uprated version. But they don't....
Anything made in China is subpar quality....they don't care about whether it arrives broken or not working....the sale is all they care about....sadly buyer loyalty is not their strength because of this.... they usually are barely a working device from factory.... depending on what it is i already decide if it is going to last long enough to pay for the cheap price.... did returning it ? or exchanging it ? be any options?? If i have to repair a new product it really has to be worth doing when New... otherwise i learned my lesson decades ago on that issue... cheap and built like a toy isn't something that will last long...lol
You need to use it fully now...slidehammer the studs to see how much you can pound it...your thick sheetmetal will not move before they break....
🇨🇦🤓🤟
Yes indeed, lucky the dent pulling is completed
What is the point all these videos on this crappy product ?
In the first video, you said you will return it !
I did opened up the case with Vevor, and instead of a return, I got this new board. So, the second video is all about how they handle us... something people have to know...
