Temu plastic welder with schematic 

"There is a limit to how much fun you can have watching someone basically melt plastic" Say to that to the 3D printing community

"There is a limit to how much fun you can have watching someone basically melt plastic" Sir you underestimate how drunk I am and how fascinating this can be.

Looks like a handy branding iron for your little sister's toy horses.

Your voice is NOT weird. Your voice is one of the most pleasing on all of RU-vid.

We use these frequently, and we always put a twist on it before we let it cool so it has virgin uncooked plastic vertically above it, we find it holds much better on the ATV and side by side bodies we repair with them. We also pre-heat them to glowing red before we sink them in, instead of warming them while touching the plastic.

You sir are proof you can attain a million followers without manufactured drama or gimmicks. Us EE nerds appreciate you more than you know.

Once you've sunk the staple, give the gun a twist and embed it using rotation. This will provide far greater rigidity than a straight push alone.

Note you should put the staples in the other direction, so it maximises the amount of times it crosses the break

Knowing temu I’m surprised it’s not just a switch that activates full line voltage across those 2 terminals

Resistive Thermoplastic Polymer Recombobulator! Nice and pretty handy, especially if hot stapling is combined with glue. Nice 73 meter. And now measure it once again just to see if it was not a Fluke! I use a 179 in my lab. More to come in the future, I think :)

I saw a video, where they used a Soldering Iron with a flattened copper tip, to mend cracked plastic. They used the metal mesh (from coax cable), and melted it into the plastic.

Wish I had one of these a week ago when I was fixing my car. Went with drilling holes and making custom staple-like things out of wire to join the broken plastic bits together.

6:48 No, your voice is not weird. We like your voice. I like your voice! Who cares if somebody doesn't. When I hear your voice, I feel like I'm watching some show on Discovery on TV, like old days. so it's not weird!!

unrelated to this specific video but I really like how he warns us when he turns the lights back on for those of us watching his videos at 3 am.

Clive, your voice is calming. Don't talk shit about your voice. You could do those strange ASMR videos with great success.

"There's a limit to how much fun you can have watching someone melt plastic." You underestimate the power of ADHD hyperfocus. I also watch my 3d printer print.

I have an old Weller soldering gun, it has a multi-turn primary and a one turn secondary. The tips were heavy gauge copper that were clamped into the secondary. It had a two-stage power switch, pull it harder and the output heat level increased. I did a lot of soldering with that gun, and it still works.

I have not seen one of these before, but I was very impressed by your demonstration. There have been a number of occasions in the past when a tool like this would have made a good repair on cracked plastic mouldings, particularly where spare parts were unobtainable.

It's simple. It works. It's cheap. No reason to change it or make it more complex. 🎉 Thanks for sharing

Makes me think a little adapter for my Weller soldering gun to accept these staples would be handy.

The wave pattern of that staple should zig-zag like a sine wave over your crack line. This way, you get multiple points of "welding" instead of just one, like your first staple. If your staple goes over your crack once, then it can be straight, like document staples, but then you need so much more of them 👍

I felt a great disturbance, millions of my little ponies suddenly cried out in fear.

I'm glad they snap off below the surface, this would be good for cracked bumper repairs

If your last name begins with M or W it would be a great livestock branding tool for your kids. Lots of fun, lots of uses!

You must have an absolute treasure trove of gadgets at your place!

"Try and hold it together" sounds like an excellent name for a song. (nothing to do with the content, just... arandom BigClive quote)

I bought a combination plastic and metal stick welder from Vevor this past summer. C$130.00 on sale. I haven't actually tried the plastic side of it yet. But the metal stick welder worked really well. We used it for some structural repairs at my restoration project a couple of months ago. It was a 3-day job, and that little welder kept up just fine. Even if it had failed shortly after the job was done, it would have been an excellent deal given the amount of weld it laid down over those 3 days :)

I use one of this since over a year. Its the best chinastuff i ever bought! My daughter had a hole in her headlight and the used one i bought of ebay had broken tabs so i cut the tabs of her headlight and "welded" it to the other headlight. works perfect and is sturdy!

I have seen these used for some pretty good repairs on some pretty expensive auto parts. With a little patience and some skill, you could use this for a ton of stuff. It is on my list, but right now I am cut-off from buying any more tools LOL.

Wish I'd had one of these years ago when I kept dropping faired motorcycles. 😁

I have one of these, mine a rechargable pen-looking device. It also came with a flat head for smooting out a surface, and some extra filling plastic rods of different sorts. Haven't used it properly yet though, only did some tests. Seems to be a useful thing to be honest. Certain plastics are impossible to glue so this is handy.

If you ever break a hotdog that's been electrocution cooked, you might be able to fix it with the Temu Welder. Worth a try but watch for the wire, they'd hurt worse than eating a pin bone in a fish. You could also bend the fastener into a shape like your initial and brand your hotdogs to ID them. No end to the joy. 8^) Cheers!

Who could smell that burning plastic as the staple went in? 😂

For some reason, it was funny to see "Made In China" on the Tesla part, while trying to repair it with a TEMU purchase.

Apparently popular for repairing plastic bumpers on cars. melt the staples in then use filler sandpaper and paint.

Yes, this welder should be a staple in any man's tool room.

The plastic repair that was passed doen to me was to melt (ideally) small holes each side of the split, tear etc and to stitch the parts back together with plenty of thread or similar. Dental floss also works very well.. You can them apply a suitable glue to the thread and plastic and even if the glue doesn't bond to the plastic it will bond to the thread to create a good repair. Glues have come a long way but there are still some plastics that are hard to 'chemically' fix. Sewing might be more time-consuming, but you can also attack parts like you might stich-weld metasl to make a solid fix in complex shapes. Thanks for the vid Big Clive.

''Let's pretend I'm a real garage and NOT clean it off''... Priceless. 😀

That's a very nice PINK calculator you have there..... 10 suspicion points.... LOL...

It looks like if a taser and blowdryer morphed together. Interesting gadget.

The number one reason I love Bigclive is that he can say the word "solder" without sounding like he is talking about a 'dirty' subject.

Awesome Video Big Clive 😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊

I bought this type of plastic melting / melding thing from china specifically to mend my sons electric car.... that thing is made out of plastic like 90% and he tend to crash a lot :D this thing can patch it back together like nothing :)

Almost guaranteed the wire is CCA, as after all it is cheaper than copper, and now almost the standard wire in the Chinese market, with all things now being wound in it, even available down to 48SWG as well, as i have seen it used in this size.

My initial interpretation of the item was that it was a [plastic][welding gun], as in, a welding gun made of plastic… presumably a bad idea. Of course [plastic welding] [gun] makes more sense.

Small tip, to help keep something together you could push the item against something heavy or something that wont move to help keep it in place while joining it together. Simple but effective, not that it matters for a short video i suppose though.

big clive at 2:30 am is the optimal time

We have those plastic bins for the automated robotic arms. Ours cracked and the city wanted $165 to replace. Bought one of these from the jungle place. Worked well. Should last for a year.

The transformer is minuscule compared to my ancient soldering gun (which does buzz when you use it). I suppose its current is resistance limited to match the staples/stitches. Must be expecting a low duty cycle to survive for any length of time.

This makes it worth it being up at 2.30 am with a cold.

I've read that you're supposed to put a little rotation on the staple after it's been driven in. Basically locks it under the plastic.

This isn't just someone melting plastic, this is Big Clive melting plastic

12:31 not gonna break down? I melted the transformer of one i got on amazon after 1 use of about a dozen staples. The thing stopped outputting voltage and it wasnt a broke wire. Could smell the "hot metal" smell pretty sure it cooked the enamal coating off the windings.

I thought this was going to be about the little plastic melted 'rivets' used in laptops in place of screws. Those things are the bane of my existence / stopping me replacing the keyboard membrane in my laptop. The things in this video I saw someone repairing a car bumper with and while it did look fixed in the end I wouldn't think it was very safe or study in the end.

Interesting device. Quite interesting how simple it is. Shame about the neutral trigger given that everything else seemed well done. Bet the little tip would be good for branding ninnies.

I have a 100-150w soldering iron that's exactly the same, I suppose this is just a seriously lower powered version, mine also has no thermal fuse, to the point it gets uncomfortable to hold and has bubbled up it's own label I wonder how hot a two prong solder tip would get in there If unloaded it out out 3vac, does that mean those elements are 3k resistance?

Oddly satisfying. It’s important to note that thermal plastics like ABS will yield the best results, since the plastic can homogenize back to itself. Would be interesting to bond 3D prints together, since it’s all entirely thermoplastics. However, I would much rather it be temperature controlled, so you don’t burn the plastic.

If this actually works fine enough, it could be a game changer. We often can't save devices we're getting at the local repair cafe because of plastic parts not accepting glue or where glueing wouldn't work because of the size.

Just had a friend trying to melt steel wool into a snowmobile hood to fuse a crack with a soldering iron, this is much less "rural" way, thanks!

I'd stick the facias together with your chosen bonding agent, then use the metal supports. It looks handy, if a more safer build was available.

just for your reference, the first staple you put in should have been rotated 90 degrees as it then gives more bridges across the crack we use a slightly more sophisticated one at work to align parts before actually being plastic welded Excellent video as always

Tesla type 2.1. Cheers clive. The things i fear most these days are either microscopic or completely invisible. Thanks for all the heads up!

I bought a " for makita " version from aliexpress brilliant for repairs, after watching this earlier I have just repaired a shelf in the fridge door bit of super glue and a couple of the w clips all fixed

It's one of those things that, looking back, would have come in handy so many times that it would have paid for itself a thousand times over. I'm glad you posted this. I had seen these before and told myself I really, really needed to grab one. Then with bike season staring to open up in my area I've been so busy that I completely forgot about it. Thanks to you, I've remembered again. So I already flipped over to order one to make sure the mighty brain fart does not strike me down yet again.

This is an extremely useful tool to have. Initially they were mainly used by auto body shops to repair cracked plastic car bumpers. About 4 years ago they cost a ridiculous price of about $300 US, so I built one myself by modifying a microwave oven transformer. I repaired many cracked plastic items with it over the years and the repair is a strong as the plastic itself. Some plastics like polyethylene are impossible to glue together but this does a fantastic job on the repair. Funny, it's the same old story with the Chinese ripping off the the design and banging them out at a very cheap price.

If you end up actually using one of these, give it a small twist after inserting the staple for a stronger and longer lasting bond, a few degrees is all that's needed but up to 15 degrees is good.

Lions often need to weld long beads of TPU. Doing it in a reasonable amount of time requires a spade solder tip.

I've used this system quite a lot in the past. The joints are mechanically strong(ish), and providing you can refinish the surface (or "staple" on an out of sight area) the end result is good. Obviously a LOT stronger than any glued joint (even epoxy), but definitely not OK for any "significant structural" purpose.

If that plastic part is ABS, all you need is a drop of acetone.

A great tool for branding bottom's, I wonder if you could get different heat inserts 😊

I absolutly love mine, it's already saved me a replacement mudguard for a motorbike (that would've been about £70 2nd hand. A replacement jack stand support for a Merc, a underpan cover for a renault, and I know it will save me more in the future. One of my better investments. Thanks for the video, saves me taking mine apart...

I imagine a lot more guys like me are finding your channel due to morbid optimism for Temu finds. My bet is you'll more than double your subscribers by reviewing all the MOST EXPENSIVE Temu tools the rest of us can't risk wasting money on. Engineers can't not engineer, so your analytic methodology and quirks would be a godsend to non-electronic "man-stuff" as well....even if you don't get to say the word "schematic" as often 🤣

This thing is about as simplistic as a Weller soldering gun, although an incredibly low power one with a better trigger switch. The last Weller I pulled apart that I bought brand new had leaf contacts within it. I would think the duty cycle is similar with about 25% (on one minute, off four)?

It's is best to hold the wire tightly with needlenose or pliers and then cut the wire close to the surface, never hold the wire with your fingers or when you snip it off the energy released will drive the wire into your fingers. Trust me on this, I am speaking from painful experience and used those same needlenose pliers to pull it out of the tip of my index finger! And if you don't hold the wire and just snip it off, it flies off and could end up in your eye or you will find it later embedded in your foot or clothing or your dog's paw if they might step on it. Dispose of those wire clippings in thre trash can. I use a magnetic parts holder to hold the snippings dropping them from the needlenose pliers after I clipped them off. Make the touchup finishing like smoothing the plastic that gets pushed out and on the sides of the openings with a hot solder iron and flat tip.

Hi Clive. Another instructional and destructional video - awesome! Am I right in thinking if there is ever any break down of the insulators between the primary and secondary on the transformer that essentially the two brass studs would be live at mains voltage? It doesn't sound like the sort of component you want a lowest bid supplier for, but I guess the whole thing is made to a tiny budget. Cheers! Paul.

I have one and didn't know the pins snapped off :0 Thanks for showing that Clive

Hi Clive I love watching your videos they are very informative. What do you think the transformer actually is. I.e. voltage and amps. It seems strange that it could be 1 volt @ 12 amps or am i reading that wrong. The sellers claim the plastic welders are anywhere between 50 and 100 watts?. Keep up the fantastic videos.

It amazes me how minimal the led indication circuit is. I wonder how much will the abused led will last

It might not be a welder, as described. PVC has a lower burning point then melting point and can not be weld and have to be melted chemically using solvents. (many other types of plastics can be weld such as PE, PLA...). But when combined with solvent (Cement) it might be brilliant handy think to reinforce joints. Might be the first think I ever get based on seeing it here. It had to be stated, that it had nothing to do with you using it but that it sounds cheap and useful.

My 120v one came with a knife adapter for melting / welding plastic. After using it for 20 minutes or so, constantly on, the device gets pretty damn hot. I ended up taking 30 minute breaks to let it cool down enough not to burn my hand.

Clive thanks for the video you show two of my pet hates 1. 13 amp fuse fitted when as you say 2amp would be ok, 2. the switch in the neutral side not good practice and that lead would not carry the fault current for long

For anyone thinking of getting a plastic welder, be aware they are extremely situational. Generally speaking if the part has any load on it, it won't work long term (or usually short term eg the next time you use whatever you fixed). Also it is dependent upon the type of plastic. For purely cosmetic things, both the stapler and soldering iron types will be fine. Bottom line: avoid things that use plastic as parts that have a load/involved in motion, though that is largely impossible. Also, if using the soldering iron type especially, respirator and fume extractor.

Can it be used to repair cheese slices😅

The Daddy Meter along with the Kink Palculator.... and transformers that are putting out! Always fun to watch, thank Clive!

Seen these before for fixing broken car trim, as you demonstrated. Might have been made to a better standard than this example though...

Using a knife or screwdriver in my other hand, I would smooth out and fill back the melted plastic for a more rigid and better-looking repair while the plastic is hot.

beats the staples and mini blowtorch method I've been using for years, bit bulky though

Ahaaa...not sure how I missed this one, but now I know how you got that squiggly burn on the bench top.

In the UK it might seem that neutral and live from mains are fixed because you can only plug one way - but in (…how do I say this politely… ) generally THE REST IF THE WORLD 😅 220v /110v AC have plugs which are reversible so they even got the live/neutral AC connection right, it really doesn’t matter how you plug it, transformer doesn’t care and the LEDS will respond to any half cycle anyway 😊

'Daddy meter' really had me 😂

Clamp two halves together and tack weld corners, then melt in four or more doohickeys. Welds/staples should make stronger than originally.

I bought over of those from Temu recently. It says it works on 120 to 240v...(I'm in the USA) which is like... Kind of true, but it takes 10 seconds to heat up at all on 120. Wired it up to my 240v welder outlet and it actually works pretty well. Under load it's only putting out one volt. I immediately took it apart to see if there was a center tap, for 120v, but no. Then I realized i could make this wireless, because I have a couple of 2.5v 500F super capacitors (also from Temu). Works much better running off the Supercap. I want to rebuild it so it charges the cap from some 18650, but that project has been on my To Do list for a while now.

It’s not really a welder is it? It’s more a melt-in stapler.

my screwdrivers are cut down too, to reach the deep plastic housings all fine

My oranges are waiting for theis device to juice them

Just about to try my new you would need 3 staples for a start. Mines' not the same as it is battery operated from my solar and got it from Alibaba but at least this is interested Note, I use either my jackery when I have to recharge tools using 240V batteries, ot the 12V USBs from my shed which has my solar panels on and 3 50AHr 12v batteries also in the shed. Saves me a little electricity rather than using the grid, but it does help (ground floor flat no access to the roof).

Bought a one from AliExpress many years ago, was very sceptical but i have probably used over a 100 metal burnie bits in it fault free, if its plastic and broken ive melted it back together!

Just after 2:08 I was sure Clive had heat-stapled two of his fingers together :-)

5:36 That 13A×240V fuse is insane for a device using only 12W on the business end. 0.1A at the plug would already work up to 24W. By the time a 13A fuse blew, the whole thing would be a molten blob of plastic.

You could use that to join cables, no more need for wago's! 👍
