[@kieferonline]

Thumbs up for association with Mr. Rossman. Having Dave and Louis in a combined video-something would get invented on the spot. Two guys I respect.

[@RobBob555]

sycophant

[@mikeselectricstuff]

Really surprised to see a brushless motor in there. How would conducted or radiated noise cause lights to flicker? It's obviously just the current draw when the heater turns on & off

[@JGnLAU8OAWF6]

Exactly! Brushless motors are everywhere now...

[@mrjohhhnnnyyy5797]

mikeselectricstuff Exactly, I have much weaker hot air station which does the same. It uses a TRIAC in leading edge phase fired controller circuit, which is the source of that flicker.

[@IlhanNegis]

yea, 110v sucks

[@madmodders]

Yes, Louis needs to not run that on the same circuit as the lights. When I'm down in some old cellars doing my work with a 2kW hot air gun, the lights flicker like crazy. Old wimpy wiring and long runs from the breaker panel tends to do that to you.

[@gandalf87264]

Induction does strange things :P

[@rossmanngroup]

Upon rewatching, by far the best part of this video is the enthusiasm Dave shows at removing the Vanta. I love it!!

[@EEVblog]

So enthusiastic it seems, I lost my balls.

[@MrPnew1]

It's OK Dave, Louis is always misplacing his balls :)

[@VileVermin]

@@EEVblog balls... oh - balls!!! kzbin.info/www/bejne/n6jVq35mo71kmMk

[@VileVermin]

couple days ago i removed south bridge from PC motherboard just using cheap HAG but with help of my kitchen electric stove as pre-heater - it was really simple but mobo now screwed like propeller blade :) :) :) ru.aliexpress.com/item/220V-240V-450W-450-Degree-LCD-Adjustable-Electronic-Heat-Hot-Air-Gun-Desoldering-Soldering-Station-IC/32272327737.html

[@deceitive3338]

Hey Louis and Dave, I own a rework/solder station and have the same issue with flickering (fluorescent) lights in my workshop. I did some investigating with a power meter and in my case at least it is caused by the logic board modulating the heating element on/off in short pulses once it is up to temperature to keep it at temp. Taking the heater off the stand also causes my lights to dim, placing it back in the holder fixes that issue immediately (while the fan is still cooling it down). The entire workshop is on one breaker, separating the lighting from the outlets at the breaker panel should solve the issue.

[@vincei4252]

I bought one of these soon after Louis's review. It is indeed very good. Compared to my existing rework station no contest for desoldering large components and BGA's and such there's simply no contest. Also Louis, is a great channel. He's a good guy and for someone who's much older than him I've gotten a few life lessons too. I like his cats too :)

[@Boffin55]

Pretty sure Louis' issue is that a US circuit is only 15A @ 120V, so 1000W is a pretty good chunk of that. The big disadvantage of 120V and small (14ga / 2sqmm) wire. Not uncommon at all to see lights dip here in North America when a bit load is switched in

[@rossmanngroup]

It could be, but a JBC JT-A at full power causes zero flickering. Maybe the Quick is more powerful, but I don't think it is *that* more powerful. As much as I love my Quick I have to acknowledge that the $1200+ price difference comes from cheaping out on the power supply.

[@ethanpoole3443]

Boffin A typical 120V US circuit may be either 15A (1800W, #14 copper minimum) or 20A (2400W, #12 copper minimum), both are quite common though in very old structures the 15A circuit was much more typical since in the first half of the 20th century a typical household load consisted of lights, a radio, later a TV, and the occasional clothes iron or vacuum and that was about it outside of the kitchen. However, the tendency towards flicker really depends a lot upon where in the AC cycle the heating element is being powered on. I would imagine they are using a random phase triac driver, which means you can be switching on a high powered heating element right at the AC peaks with fair regularity and if your circuit is already loaded down or has a fairly long run back to the mains panel then you can get noticeable flicker, particularly with fluorescent and LED lighting. You might well be able to get away with swapping the random phase triac driver for a zero-crossover driver and resolve the flicker issue so long as long as the temperature regulation loop is not adversely altered.

[@rasz]

>cheaping out on the power supply there is no power supply, heating element is directly switched to the mains

[@allesklarklaus147]

rasz exactly

[@allesklarklaus147]

Boffin Also it is an old NYC piece of shit building, probably just like 3 breakers for the whole place and 16awg wire

[@HopWorksET]

Once again sir you hit on ALL the key points that allow me to justify purchasing a tool like this. So entertaining AND informative. Thank you again Dave! You are just flat out AWESOME!

[@electronicsNmore]

That "Quick" unit is very nice. A while back I picked up an 898D unit which I like very much, I stole it for $45.00 shipped.

[@zaprodk]

It's quite common for these stations to "hide" bad temperature regulation and give you a nice, round reading as long as the temp. is inside a small window :)

[@rasz]

its mianzi, aka lying in your face being more polite than bringing bad news, classic chinese

[@ales_xy]

Same with cheap chinese scales. They're good value for the price, but absolutely not in the professional instruments league. I can't imagine that someone would seriously suggest this as equipment in real lab :-)

[@homersimpson9257]

I bought one on the advise of Louis, really a great product. I was following Dave some years before Louis, i'm glad to see this review on this product from Dave too.

[@km5405]

I love Louis 's channel, great life lessons and lessons on board level smd repair work all round. ......... also time is money, the quick 861DW will earn back itself in a week if you are a professional.

[@MrDoneboy]

Dave and Louis...Two of my favorites!

[@gjsmo]

400C at full airflow seems a bit excessive but I can't fault the speed, especially for the big FETs. I've used whatever hot air station Sparkfun sells before but this one definitely seems worth the added cost.

[@mahound9]

I have the sparkfun station & use it for repairs. Gets you there, cost me 200 plus COD charges in Canada.

[@jllemus]

Probably someone already commented on this, but it seems there are two models, the 861DW and the 861DE. The DW only goes to 120 l/min and the DE is the one that goes up to 200 l/min. So the display is actually indicating the air flow in l/min.

[@cogliostro841]

I also have this Quick Station. There is nothing in this price range that can compare. Hakko and Weller is almost 3 times the price of the quick. I have mine for almost half an year and I'm still very impressed. Unfortunately mine has a "beeping" noisy motor with high frequency sound -.- but beside of that if you searching a hot air station right now. There is no way around the quick

[@quantumbubbles2106]

I second this - Quick appears to be a truly high-quality manufacturer. My 861DW, btw, doesn't make any beeping or otherwise annoying noises.

[@gnagyusa]

Dave and Louis are both awesome. It's nice to see some collaboration between them.

[@CPD-KD6-3.7]

First off. Shout out to Louis and Dave, both excellent youtubers in their respective categories!

[@allegas1]

Yay, Dave! Atten consumes 280w and delivers 28l/m. It is standart blower fan, equipped in most of chinese soldering stations.

[@deadfreightwest5956]

I had to laugh at the "LEAD FREE" stencil.

[@chasingcapsaicin]

Not even watched it yet, but thank you Louis been waiting for this since he mentioned he sent you one. I have been trying to get a filter right to kill the feedback that messes with the lights since I got mine.

[@manuel-zx1wn]

i just bought the Atten 858D+ for 27 euro.... price-performance unbeatable. for hobby stuff its great;)

[@aneeshprasobhan]

wait what the heck

[@chrisalexthomas]

I came here to see the 858d in action because I just bought one and wanted to know how it would stack up against a professional machine. Thanks for the video. It really helped and I think I can do my amateur stuff with the 858d just fine. I just need to be a bit more patient. Great stuff!

[@haraldvanarkel4429]

I always use the stand the other way round. That way the nozzles don't fly away but fall in the tray instead.

[@Daniel-hd7gq]

The 861DW is the 120l/min version! The 861DE can do 200l/min and has 1200 W

[@chinaphonefixteam6300]

QUICK 861DW professional mobile phone repair and repair station, using brushless vortex fan, adjustable air volume, wide range, can be used for a variety of purposes. The system has the function of automatic cooling of air volume, which prolongs the life of heating elements and protects the hot air handle.

[@betamax80]

It's great to see collaborative youtubing. Well done sir Dave!

[@Stabby666]

It's funny watching dave do a similar job to Louis, but without adding 6 gallons of flux to the board before desoldering :)

[@laernulienlaernulienlaernu8953]

It's just like most tools and equipment, the more you use something, the more you can warrant spending on it. I think the cheapi would be adequate for most hobbyists but obviously the one that's 4 times the price is going to be better

[@greywolf271]

Dave Approves ! That's why I bought one myself.

[@sykskysyk]

This one's a forum classic, many many people have been recommending it for a long time.

[@ingmarm8858]

Seriously Dave you're at one point suggesting that radiated EMI from a bench top device like this might cause the lights in a workshop to flicker?!?!? Too much coffee today?

[@nrdesign1991]

Finally decided to get one of these, after having it at work for a year. It's a great station and very nice to work with.

[@Der_Arathok]

9:43 Isnt that sleeving around the wires for heat protection?

[@acertech]

This is not the 200l version. It is the 861DW 120l version and 861DE are the 200l that I own. :-)

[@ArumesYT]

Funny how a review of an expensive hot air station actually shows that the cheap Atten is more than adequate for my needs. Added that one to my wishlist. 🙂

[@bobweiram6321]

It's even funnier you can't tell the difference. There's a reason it's a big seller.

[@ArumesYT]

@@bobweiram6321 Funny how you assume I can't tell the difference with absolutely nothing to back up that assumption. If your soldering is as bad as your reading, you'd better stay away from electronics completely.

[@rubino7]

Just FYI, this thing is about 150 euro shipped from AliExpress. This is without a sale going on so you could shave off another 10-20 euro.

[@corenelius]

My brother in-law used to work at the Adelaide Showgrounds setting up and repairing power distribution points for show rides etc. They commonly referred to using two cable ties to secure flexible leads within an enclosure as 'Carnie Proofing'. Apparently the show-ride operators, or 'Carnies', had a reputation of being a little rougher than most with flexible power leads, often driving off with things still connected. Two cable ties = 'Carnie Proof'

[@tedmich]

people also like the Quick 957DW+ for $113, only 580W and 100LPM air, some issues with transformer coming loose (vertically mounted-Doh!) but good if all together

[@mattdunlop6056]

honestly that temp memory feature on the quick is useful. I have an older cheaper model and switching between desoldering temps and lower temps for just melting stuff or shrink is a pain, many of times have I grabbed mine without thinking just to hit some heat shrink and its set at 400C

[@Alaakso]

Here's my thinking.... You set the minimum temperature needed for the desolder and then adjust the power/speed with airflow, since the the heating power carried by the airstream is depended on temperature and airflow on equal proportion.

[@button-puncher]

WOW. I always thought you needed some special rig to remove those big BGA chips. This is so cool. The build quality on the 861 looks really nice. I just decided to get the 957DW+. It looks like the middle between the two models. It has the remote blower, which I like. I'm guessing that you could quiet the blower down with a bellmouth intake and some foam.

[@LogiForce86]

Dave, shouldn't that stand be used the other way around? Both for the attachment removal (so the attachment falls into the cup below) and for the weight of the cable pulling the hot air iron into the stand instead of pulling it off of it like in the video at 4:50. 🧐

[@whatsupchuck6179]

Hello, you seem very knowledgeable of this product. I have this station as well and it's no longer heating properly. I replaced the heating element, and it did not fix it. It's barley heating at all. What is the most likely part that's causing it to not regulate the temp?

[@PolakeXD]

Definitely very good reflow station. I use it since four months and it is actually very good. Already repaired four Xbox One's and an Galaxy S6 motherboard with it.

[@NewShockerGuy]

I just picked this up as a side fun project to learn. I can't seem to desolder smd leds for some reason. Either I'm not getting it hot enough or I am afraid of torching stuff..lol this is my first time and I have mulitple PCB's that are dead and just practice on. I can't seem to get the hang of it yet. I know how to solder normally but totally new to hot air rework stations.

[@thomaslindell5448]

When it gets hot those nozzles have a tendency to fall out I ended up drilling a small hole in the collar and tapping it to put a small screw to retain the nozzle

[@TheModernVictorian]

when you wiggled one of the wires into the screw terminals, I could see the copper poking from the other side move, might wanna re-crimp that one, take a look.. 13:26

[@obe726]

Louis is a legend

[@TheBitKrieger]

Wait... Dave showed 200L/min for the quick - but all shops and sources i find advertise it as 120l/min just like the atten?! Okay the Quick UI also shows 1-120 airflow... so nothing about 200 - so is the quick really better than the atten?

[@GadgetReviewVideos]

Yes, he was wrong about the 200. Is it better,? Ot depends on what you use it for. It does heat up faster with the 1000 Watt heater, has a better whirlpool 3 phase brushless motor and motor ESC controller board, proper mains filtering, program able to switch faster between ore-set modes (most hobbiest might not benefit from this, but can save time in production or repair shops) ground strap plug in the back if you don’t have a ESD mat (probably should still have one for professional work) and I think the Quick will last a longer longer for the money. Most I’ve seen sold are 2 year and 3 year warranty. But it mainly depends on what you really use it for, how often, all day at work or hardly used as a hobby.

[@theirishscion]

Quick sell a 200L/minute model (QUICK856AE) with a larger motor/blower combination and a 1200W head. I believe some confusion is taking place.

[@TheBitKrieger]

Gadget Review Videos Ok, overall the quick sounds higher quality - what I am still confused about: if both have the same airflow: how can the atten perform so much worse (slower desoldering time) - I mean the temp is regulated so more power does not give you an advantage if you have the same airflow?

[@theirishscion]

The Atten is lying about output volume. And probably temperature. The quick is not. Simple as that really.

[@rossmanngroup]

It's hard for me to believe any of these tell the truth. My WHA900 feels like it has the same max airflow as the 861DW and it was rated to 50L/minute. Anything that advertises over 25L/minute should be good. It's the crappy hot air "pencils" built into 3-in-1 stations that are usually garbage, limited to 5-15 L/minute. Unable to do anything worthwhile with those and they often cost as much as a dedicated station.

[@SevenDeMagnus]

Cool both from the epic Quick brand (KSGER also used their hot air SMD workstation system for KSGER's epic solder and desoldering tools:-)

[@darrenthompson3696]

Hi Dave, if your looking for a high quality soldering station/system take a look at BLACKJACK SOLDERWERKS Soldering stations. You get a lot for your buck, they have kits available for providing a complete solution. I recently purchased a BK6000 system that included a set of soldering iron tips, desoldering gun, hot air gun and all the hot air gun component attachments. They are sold by a company called circuit specialist Europe. The only problem with them are that the hot air pump is a bit noisy but if you are not too bothered about the noise , the equipment is brilliant

[@BryanTorok]

At one-fourth the price, the Atten looks perfectly adequate for most home users. I would expect that a slightly smaller nozzle would concentrate the heat probably increase performance slightly.

[@ctoforhire]

"...just stick it up the clacker" - I nearly spit out my coffee laughing ;)

[@c0ffeeman]

People. Listen up. Go to 3:13 and imagine the rework iron as a phallic object.

[@ReinForceOne]

@3:25 - thats a shot from Louis towards Jessa from ipadrehab (who ordered these 45° nozzles first but Louis got them b4 her)

[@debeeriz]

for big ground planes use a $25 heatgun from bunnings and buy some tips from ebay/aliexpress from about $5 up to fit it

[@juanee2]

It would be interesting to compare the Quick 861dw to a more professional and expensive alternative, such as the PACE ST 325 (ST325).

[@antilogicnz]

Easy way to semi-bypass the RCD, (though is potentially dangerous in the wrong hands) disconnect the appliance earth and connect it to the neutral. (its still earthed via MEN) make sure you 100% check phase/neutral polarity. Any potential leakage to "real" earth will still trip the RCD, but current in the earth wire wont. handy for PAT testing on construction sites.

[@Mythricia1988]

This sounds suicidal at best. In many (most) countries, there is no difference between live / neutral in mains wiring, it's just a convention with no practical importance. It's literally a 50/50 chance you'd be connecting earth to live.

[@Sam-hj5ok]

Anything expensive can manage to look good no matter how you look at it

[@ronjones4069]

I think the light flicker is from that 1 kw machine turning on and off.

those copper traces that came up with the nvidia chip, they seemed intact, could you apply some some sort of epoxy blue to the traces, and stick them back to the board ?

[@davidgrey943]

I have question the parts that you removed off the boards could they, for example, be reused or were they just a one-shot removal for an example replacing one part for a new part type of replacement not ever used hot air tools for part replacement or board build.

[@CyberlightFG]

I took my 858D apart before powering it up. No worries whatsoever.

[@GeorgeGeorge-xj2bc]

Well even exactly the same components they dont have the same time of reflow if they are not exactly in the same location on the board and especially when the pcb is a multi layered graphics card with heat transferring zones acting as a heat sinker.Then there are huge differences and thats why the bottom preheating is used for in such difficult to rework pcbs.

[@xenonram]

Khron's Cave 6 different comments?!? Seems like you've got a lot to say. Maybe you should email him.

[@khronscave]

They're just remarks as i was watching through the video (hence the timestamps, so people know what i'm referring to). I don't think any of those are anywhere near what i'd call private, nor warranting an email. Others are welcome to reply with agreements, disagreements or other comments.

[@khronscave]

And besides, KZbin likes "engagement" - the principle of "the more, the merrier" :P So if anything, i'm helping the ratings or whatever they're called.

[@GadgetReviewVideos]

That’s a whirlpool brushless motor, I think it’s a three phase with temp sensing wire also for 4 wires. So the motor board has several mosfets on it because it’s a electronic speed controller for the motor. It might be whirlpools motors board as well and cheaper to buy in bulk as the pair. If it is whirlpools esc control motor board it will ensue better safety if the motor fails and much better performance properly running the motor.

[@khronscave]

I figured it would be a brushless motor, but you rarely see ones so small, with "external" drive circuitry. The last (and only) time i saw one, was the fan in my old Tek 2230 scope (a little 60x60x25mm job).

[@atjfc]

I bought one of these, well, the Yihua 959D. After one minute of turning it on, the fan failed to start and the handpiece melted down after the element housing began glowing red hot. Almost started a fire in my house. Smoke and melted plastic everywhere. Dangerous is all i can say.

How much voltage do you have in the socket? edit: I have now open the Device, there are a electronic power supply with two 200V Capacitors, not good

[@MrPaddy1000111]

I thought this version (861DW) has 120L of airflow and the 861DE version had 200L which explains the 120 resolution?

[@oscarmarfori613]

Looks quite good in performance but it sure is hurts the pockets deeply 😁
