That circuit works as follow: The resistor of the solder is always on (provided you don't press the switch )There is a rectifier diode bridge and Capacitor circuit that converts AC to DC needed to power the inner solenoid acting as an electromagnet that feeds the pump . When switch is pressed, the piston is attracted to the solenoid and creates vacum sucking the soldering the rod of the pump pusses the arrow that opens that spring loaded switch at the end and opens the AC circuit turning off the solder heat. When you release the switch, the inner spring put the piston back spitting all the solder inside.

Thanks for reveiw I'm from LAOS 🇱🇦

Given the red and blue wires are different colour to the red and blue going to the switch then I would imagine that the mains is being full wave rectified with a smoothing cap to take out the ripple. No earth is required given that all the parts are insulated from the mains. The handle switch is used to provide power to the solenoid, whilst the other switch at the back, removes power from the solenoid once the solenoid has been de-actuated, by releasing the button. A simple plunger at the back of the solenoid provides this action by the looks of it, probably driving the solenoid in the opposite direction by back EMF action of releasing the button. Pointy looking bit of plastic at the centre :) Effective by its simple construction, just a tad fiddly when it comes to cleaning. Thanks for the video as it gives an insight into the operation of the desoldering iron.

Just got mine today. Only 7 days after ordering (a small miracle coming from China) It has 4 tips (3 spares and 1 installed) and it has the same Euro plug and a really cheap adapter. I plan to change the cable out for an Australian plug. This is why I came to your video.

I wonder if these are worth buying, and improving/modding them.. they're a tiny fraction of the price of the next tool up in it's category

Just got mine on Saturday. 4th connection I tried to desolder and I got yellow sparks from the element area and it caught fire. Lucky I hadn't left it on and walked away.

I just ordered what looks like a newer version of this on aliexpress that doesn't seem to have the strain relief issue. How has yours held up over the year or so that you've had it? Is it still working?

I found this after looking at this item online and this videos awesome! Your very entertaining and your little rants were gold, but sadly true for the most part. A lot people don't want to know because they think its to hard haha.

I heard you ramble over there about youth havin' no clue. Well, I might have to agree. A thing in my room short circuited and it blew the fuses for the whole floor. and I hadn't even had the chance to find WHAT short circuited in my room and unplug it, and the other guys on the floor had already turned the breaker on again! As if it's just a joke. Breakers break circuits for a reason! You DO NOT just turn them back on! It seems to me that so many people are never told about the significance that electricity has. The facts. How basic stuff work. Were they never told to reason, and think "Hey, why did the breaker go off?". They turn the breakers back on like they open a window when it blows closed; maybe they grew up with electricity the same way as air: it was always there. It was never new and taught about.

I had ordered one and it has a US plug and the plastic is black and not blue. It still says it is 220V, but I live in the USA? How is that going to work?

Where can I buy a replacement heating element for this extractor? Please

Hi, I would like to ask you for a small favor if possible. When disassembling my desoldering iron, which is the same as yours, the four cables that go from the tip and the switch to the motherboard came loose and I don't know how they were soldered. Could you tell me or send me an image? and thank you very much for your videos keep it up (sorry for my English I'm from Spain)

The air that comes down tube as to go somewhere. But if someone fills the outlet with glue.

To secure the cable clamp and cable, use some super glue..

Hi, I'm considering buying a desoldering pump like this one and I was wondering how this thing kept up over time. Do you still use it? What's your experience after almost 3 years. Thank you for this great video.

In the back there is a thermo switch for the elektromagnet! The cable tie blocked them. Dont play with electric!

The pump is working on DC? The diodes form a full wave rectifier with a little filtering and the heating works on direct AC.. It seems. The wiring looks flimsy and unsafe. They've stuck no earth because its all plastic case. Under fault conditions provided you don't touch the heater... Metal you technically shouldn't get a shock. For the sake of making future videos please completely unplug any devices 👍 personally I would use a separate soldering iron and make the pump work on its own. If that was a British item, it would have the correct safety markings. Too many items coming into the UK just AINT safe.

No links? Also, those wires are brown and blue. Standard colours in Australia, and possibly China for Active (Live) and Neutral (respectively)

If you ain't broke don't fix it

Move too nervously. It's painful to watch the video. However, it was good content.

The other guy use this and removed ic fast. You took it apart before you even tested it now yours don't work. When I get home , I try mines, if it works right away , I assume something you dis was a mistep. Can I trust your work?

You lose my time................ At the end i remember only Multi-Bla_Bla_Bla.

just plug it into GFCI outlet and be done with it. this is a clown show.

2Tips 1 at least try it out before you break it 2 dont make video evidence of how you invalidated the guarantee

You look unnecessarily stressed and frustrated through all the video. It's unnerving. Keep calm. We know it's sh1t.

I had one before, totally rubbish.

I think you just got into too much of a faff and worried too much about the plug not being earthed,I came here to see if they were any good,you were faffing about too much and read darkstatehk's comment and found another video instead.

Talk to much...just get to the point...

I wish I would have watched this video before I bought the very same model. It's a complete pile of shit. I've never fired a handgun before, but the recoil on this contraption when you press the red button is horrendous and probably like firing an actual gun.

You make it so dramatic 🤦
