To make it clear: This desoldering pump is a piece of crap, DON'T BUY IT! But since I already had it why not have a look if I can make it usable.

[@nickolasgaspar9660]

you were unlucky. Yours is defective. I have one and works like a dream. Other reviewers have being impress from this tool. Sure there is an issue with heat isolation and the emptying mechanism but for 10 euros is great.

[@MakenModify]

@@nickolasgaspar9660 Possible. I only had one and it was broken ;) That happens with cheap tools, QC is non existent and you have a good chance for a broken one. In the case of this thing I found out mine was a cheap clone of a cheap tool so... yea. You are right but at the same time I still would not buy it again ;)

[@nickolasgaspar9660]

@@MakenModify well to be honest I bought mine from a local seller and it is distributed under a German brand. So my chances of being intact were elevated. The vacuum is amazing and it works great when the parts are not on a large patches of bronze.

[@nor4277]

Thank you for the info ,I was thinking of buying that model too because it cleanable

[@ingenierocristian]

I modified my pump with a stronger spring and worked well

[@UpcycleElectronics]

The regular suckers (without the iron) always seem to get clogged up near the tip. When this happens I use my iron to remelt and clear the tip. This little tool you showed here looks like it would clog up just past the heating element in the middle of the iron. Is this the case? *A couple of unsolicited tips:* A trick I use with the regular cheapo solder suckers... If you cut a bit of heatshrink that is just a bit longer than the tip of the solder sucker, and apply it there are 2 benefits. One the heatshrink will add an easily replaceable thermal protection layer for the tip, and second the extra length of heatshrink past the tip will allow you to narrow the size of the opening, greatly increasing the power of the device in a smaller area. If I can ever get well enough to work on some bigger projects I'd like to build a 3d printer myself. What is wrong with the cheap RAMPs board? Is it a certain model or something specific to look out for?

[@MakenModify]

First of all, thx for the tip, will try it ;) had no problems so far with clogging on that one. This Ramps board was by far the worse pcb i ever got from china. Some connections were not even soldered, several shorts on the board... really bad... but most ramps i had so far were ok but this was was awful xD hm.. i've build 2 printers so far (own design) and some for the university, most run on RAMPS and that is 90% adequate for most printers. Only if you want some special features or kinematics this may change. I rund my printer on Ramps+RaspberryPi (octoprint). Btw. after long time there will soon be a video on my last 3d printer design ;)

[@UpcycleElectronics]

Make'n'Modify Thanks for the reply. I need to read into that R-Pi setup. I have a spare Pi3 laying around that needs a home. I thought the Pi couldn't do real time projects like this. When you say there were "shorts" on the PCB, were there any shorts under the solder mask? I'm currently working with one of the developers of the AVR Transistor Tester project (the little component checking LCR/ESR meters sold as cheap kits from China). I'm trying to collect all the information contained in different forums from around the world, and put together a reference for everyone. I've collected data on most of the different failures people have experienced from the Chinese Transistor Tester kits. I have seen 1 case of bridged connections under the solder mask. It was on a PCB with a red solder mask too. The most common problem on these little devices is when the microcontroller is shipped without programmed firmware. -Jake

[@MakenModify]

The Arduino with ramps dealsy with the real time stuff, the pi just connects to the arduino ans provides a web interface to upload gcode, control the printer, check the webcam and so on. means i can leave the room and monitor the printer from my smartphone. No the shorts were mostly due to unclean soldering as far as i can tell, did not check it in its entirety ;) since it was visibly bad i just got a new one and saved some parts

Nice video :) the only thing I would suggest is to earthen the heating element because you never knew when it will fail.

[@MakenModify]

yes... you are right... this is more a how to make something that is unusable into something useful, but yes since it is now a metal case, an earth line would be a good idea ;)

[@yiyou6529]

The desoldering pump you modified cost about 4 euros. You will see some safety issues if you unscrew the cover panel near the end. Please make sure you check those connection instead of getting zapped some day.

[@neilritchiecaguioa8593]

Thanks!The Video is helpful, I already bought 3 YiHUA 929D-V just like that,But different color to assure no more Desolder pump busted and disturbing your work,So this Video proves that it can be fix or Mod. I'll try that but on no 3D printing style

[@yongminhuh146]

Have you try to grease the o'rings inside sucker tube?

[@ayan.debnath]

What do you think about - adding few drops of oil and changing the spring?

[@MakenModify]

honestly I don't know. This was 6 years ago, I meanwhile moved on and bought a proper desoldering gun. (had to desolder switches from some old mechanical keyboards)

[@juanangonzalez399]

I bought the same shitt... desolder from Aliexpress and I put it into the bin. It was working good for 3-4 hours.

[@amsgomes97]

I've Just fixed the crap electric chinese sucker. The problem is the silicone ring seal that is leaking. To fix, I just applied silicone sealant to the ring taking care to not close the central hole. Re-assembly the sucker and then apply another coat of the sealant to the plastic base and the sucker. After this, the sucker really sucks a lot of air.

[@alexteo2022]

Hi...you should put some grease and it should work! and more....from the second one just take that spring and add it to electric desoldering pump, it will fit perfectly and with 2 spring and some grease will have huge sucking power ;) . There is another model with yellow handle that works perfectly.

I use the same tin extractor and it's fine. So either you came across some rubbish, or it's the fault of the user's hands. I also have a vacuum pump and this will do exactly the same job for a few crowns. But you need to know how to do it a little, but I think that if it arrived already bad, it is for a complaint. But how to claim it in China, right?

[@MakenModify]

Yea I think it was a cheap knockoff of a cheap knockoff. But thats an old video. Since I'm into mechanical keyboards where I sometimes have to desolder 100+ switches with diodes (so 4 joints per switch) I got myself a automatic desoldering gun with pump. This was the try of a poor student to save a buck 😅 the engineer with a job and family values a his time and a good tool 😬

[@ibringthelastwords1358]

Hi I wonder if you can attach the Engineer SS-02 on that 🙄

[@MakenModify]

Probably, but a SS-02 and a TS80 will work better together than that thing 😉

[@ibringthelastwords1358]

@@MakenModify Hi, I got one from our local online shop for just around 5 dollars cheap yesterday. One thing I noticed is the spring was lose so I twisted it a little bit and voila it works very good. Also There is something a piece of silicone thing on the gasket that maybe blocking the tube so I removed that. You're right haha 😂the SS-02 is more than capable than this thing but its a 30 dollar tool expensive but its much more reliable and you can use it for a long run.

[@lachlan1971]

There is an even worse model available where the plastic coated mains cable cores are 0.5mm away from the heated part. I am too scared to use it.

[@MakenModify]

Oh sounds bad 😅 stay save.

[@lachlan1971]

@@MakenModify I took it apart and it was even worse than I had first thought. There was no real element, just some sort of heatproof material wrapped with very rusted iron wire. And the wires were all melted. I threw it in the bin. I kept the power cable. The only useable bit.

[@nor4277]

On eBay I found a orange one that looks like yours,it cost 7.99 or 8.99 ,mine works perfect every time,and comes with a cleaning rod,and it makes very clean removal of solder.

[@MakenModify]

yea I had the orange one too, it worked good, but eventually broke and was not really repairable. So i thought i might try out this one... but the orange on was better ;)

[@superpooper_2030]

There is a version with aluminium body model 845 which is mere 20% more expensive.

[@jonathanhendry9759]

A worthwhile project would be to somehow make a pump like that out of a ts100 soldering iron - the $50 microprocessor controlled adjustable-temperature one with the OLED screen.

[@emmettturner9452]

Better yet, I’d like to see the open source aspect used to make a proper desoldering iron using replacement parts that’re already on the market. Like, but the Hakko clone from an Aoyue station and use the microcontroller to control a solenoid for better suction… either a Venturi with a pancake air compressor or a vacuum pump that keeps running after you trigger it so that successive pulls will be stronger. Example: Short pull to start the motor and open the solenoid (low suction). Place on joint while motor is running and solenoid is closed and pull again (max suction) Countdown resets and motor runs for several more seconds allowing for successive pulls at max suction.

[@proiecteelectronice4120]

Hey i like the pad of your table where can i buy one like your pad?

[@MakenModify]

It's a cutting mat i bought at a local 1€ store. Typically you also get them in craft stores or on ebay/amazon.

[@dedskin1]

Adding a Compressor to it is an ultimate MOD, then it works like those expensive units ,i just got this one as i ruined 50$ AMP board while trying to change some components , so i got it , for me its worth it weight in gold :) and you get an option to mount a compressor on it .

[@MakenModify]

Hehe good tools are worth every penny ;) But on that one i cheaped out and wanted to get it going anyways :D ... since I got a vacuum pump recently I'll think about how i would do that. thx

[@dedskin1]

i dont exactly know how my self as well, but i think i remember some time ago, someone did it here on Tube with instructions, bet we can find it when time comes for such project , i still didnt try mine to see how it works , but i see here its as good as i need it to be . Great vid , thanks .

[@acmild]

Can you just mod the suction rubber part?

[@MakenModify]

AC Mild maybe... There are quiet some mods you could do instad but I just did it and recoded it without much planing. Easyest might me to change ore stretch the spring to give it more force.

[@garrygemmell5676]

Bought the yellow one from China it was ok at first but the tip starts to degrade very quickly and solder buildup inside these things soon stops them from working and you cannot easily open them to get the solder out - Think i will stick with the manual solder sucker - Nice mod though!

[@MakenModify]

Jea it's a piece of crap... The mod made it work forme for a while but I soon upgraded to something more useful

[@Unnaymed]

Great work thanks :)

[@JorgeVictoria]

Only add the spring on to , I so on other video lol

[@MakenModify]

Also possible, but i like to overengineer stuff ;P

[@superdau]

I bought the same thing some time ago. It developed a crack at the sharp corner right where the pump seals against the hexagonal plastic part near the heating element after maybe 20 "sucks". An obivous weak spot (I guessed that would happen right when I had it in my hand the first time). The designer had no idea about stress relief. The heating element wasn't soldered fo mine either. But I have to say it was one of the very few china products that really are crap (for what you pay; another one being a crimping tool that had completely unuseable jaws, because they crushed the crimps instead of folding them). Aja, und immer wieder lustig wenn man in deutschen/österreichischen Videos Pollin Werkzeug sieht ;) (das Popel-Ding mit dem blauen Sechskantgriff). Deren Qualität ist zwar auch oft nicht mehr als Ebay-China-Niveau, aber einige Dinge sind dort echt ein Schnäppchen.

[@MakenModify]

yep this is actually one of the bad examples for cheap products from china. And yes you can't get around pollin ;)

Please don't buy this horrible grey market copy! You can get the original Ningbo Zhongdi ZD-211 rebranded by major local established suppliers, it's much better made, and should correspond to basic electric safety requirements with proper crimps and cables. There isn't even much of a difference in price to speak of, ZD-211 is about 10-12€, and you can probably find one for 7€ or so if you hunt around.

[@MakenModify]

Yes this is thing is pretty crappy. I don't know how much of an upgrade the "original" for 10€ is. I would honestly tend to not buy either of both... I already had it and needed it to work for a single project ;)

[@SianaGearz]

@@MakenModify Well it's enough of an upgrade to guaranteed not electrocute you, and to work for 10 projects or so straight out of the box without having to fiddle with it and try to fit another extractor to it. And then i heard the plastic gives up, so... no, it's not a high quality, high endurance item either. It just about clears the lowest bar and stops right there. This one doesn't even get that far. Zhongdi is a fairly serious tool company. I have been using their 929c soldering station for 15 years - it's got the punch, it regulates on the dot exactly with only a modest lag, the fit of the tip is excellent, the tips resist wear pretty well. With some duds here and there, and you shouldn't expect magic out of lowest end budget tools, but they're an older manufacturer and did some contract work for established brands once in a while.

Don't buy shit tools kids.

True but I tended to cheap out when I was a student. And a proper desoldering gun costs basically 50x as much and if you just need it once a year... but yea, at least don't buy this shitty tool, I guess ;)
