content: I don't know about that station. I got a Best BST863 on the cheap from banggod. Two were dead on arrival. Third one worked. Banggood replaced all. Station is working good and they are now shipping from China with increased prices. It looks as if you could get the last one from banggood CZ warehouse saving a little money. Here's the link but you are at your own risk, don't blame me if it's dead on arrival:https://www.banggood.com/BEST-BST-863-1200W-220V-or-110V-Intelligent-LCD-Touch-Screen-Heat-Air-SMD-Rework-Station-p-1431173.html?cur_warehouse=CZ&rmmds=buy&ID=523698Stahlwerk, AFAIK, is also a chinese brand but it seems they care about quality more than chinese usually do? I have no experiene with them but watched some good reports about their MIG/TIG equipement, so you could give them a try.People seem to agree that Quick 861 is good at work and quality made, but it's more in the 300 bucks range

content: From the comments on that video:@iMa Mobil Apple Repair In general, we import wholesale machines of many brands, for people who resell in Mercado Libre and other platforms, we also sometimes sell balances of machines that are left. I have tried, seen and repaired many machines and most of the time between one model and another of the same brand and of a similar price range they are almost the same, only the casing and the control card change are very similar with almost the same components in different position but basically the same, they use the same resistors and the same fans or pumps, sometimes they add an extra ground wire. So in terms of performance and temperature stability it is the sameI have to agree. Best BST-863 seems to be a clone of quick 861. IIRC, fan and heater would be the same? About the Best... you'll find spares if needed. You can get more details easily, there's a thread about that station here:https://www.eevblog.com/forum/reviews/best-bst-863-hot-air-station/Don't miss my heater glowing red hot...However, as said, Banggood sent me another working unit (third one) After that I repaired the fan and changed the heater, so I have now two working units.If you are on a budget, you could try any of the clones. If you have deep pockets, go for the Quick.

content: Unless you go for the cheapest ~50$ garbage, any modern digital station should have good enough t° control. The more important aspects are durability and whether you can find consumables easily and at decent price. If you have to throw the station in the bin once the heating element or fan goes bad, it's not a good deal at all.

content: Vevor is only vendor in EU as well as the US and Canada with warehouses and staff who barely speak English. This Stahlwerk seem to be either have assembly facilities or assembling under strict German+EU electrical regulations. Plus 7 year warranty for not moving parts. My only concern about this particular station is its a bit obsolete anf can be a problem with parts, I mean spare heating elements etc. On other hand the price yes, cant see the reason pay extra 80-90 euro as 80% of my work is soldering iron and hot air is on occasional side. Yes, have feeling it would have lack of proper thermostability on changing airflow speed and temperatures unlike Atten 862D is almost perfect on it. Btw read some reviews where people claim whether Quick 861 or Atten 862 work idealy only first year or two then get slower air flow, and so on and so on.As to angled and square nozzles, hereYihua official store at aliexpress sell this kit a bit dear for just nozzles, in correspondence with seller now in order to get only angled ones.https://www.aliexpress.com/item/1005005253381888.html?pdp_npi=3%40dis%21USD%21US%20%2432.00%21US%20%2430.40%21%21%21%21%21%402101efeb16845174078161674e679e%2112000032370863327%21im%21%21

content: Stahlwerk is a chinese company. It's like Sieg: lathe/mill "designed" in Germany... made in China. Made in China doesn't matter; quality does. 7 years warranty could mean something, but we will never know unless somebody buys it and writes a report.Quick (which is a well regarded brand) and Best (which isn't) use the very same spares. I guess the only difference is quality control. Not a minor one. If you get the Stalwerk, it would be nice if you could open it and send some pictures.Edit: the cradle is the same in all quick/best/yihua/stahlwerk. I would bet they are all the same inside, too. In the thread about BEST BST863 you'll find the links to the spares for fan and heater. If the handle fits in the same cradle, the heater has to be the same too. Having 7 years warranty, I would go for it, no doubt, and quite probably get a Quick equivalent station for 1/3 the price.Even my BST863 are working good since the good one came to me and I fixed the DOA one.

content: Agree with you, but at least they have to strictly comply EU electrical regulations positioning themselves as German business etc, which is really good.At least to my email replied a lad with german name in very good English, unlike Vevor peoplle obviously using google translate. As to the model itself, the only attraction here is a price at the moment, 50% off sale for say 200 euro I'd go for Atten. That Bst station looks attractive as well, the only thing which stops from buying it, the touch screen display.Considering Chinese quality control and components quality the simplier the better ))) I#ve found at youtube only one video regarding this Yihua 993DM II the Stahlwerk is a copy from, by some russian lad (english subtitles are available). Inside, well the pump is way smaller than Atten's or Quick's so that I really doubt about honest 120L/min. The hose unlike Quicks and Attens looks to be more rigid and kinky. But you are right you cant make any judgement until you get it. Do you reckon if EU company states 7yr warranty, they can avoid it somehow under EU regulations?https://youtu.be/Nh6_ryt2mMg

content: Smaller? I'm not really sure. Perhaps there are less things into that case? Please seet attached pictures of BST863. It looks like Yihua is really cutting corners?Fan on this station is about 3" diameter -76,2 mm. It's the original DOA fan that began working after some disassembling-reassembling. Heather is the new one substituted for the burned original one. The nozzles you postedwill not fit, this heater is 27 mm diameter at the point.Edit: my bad, I just checked and my nozzles are indeed 23 mm diameter, it's just that they go inside heather's point, not outside.So it look as if you could get replacements on Aliexpress for both the fan and the heater, no matter if you get the station from Quick, Best, Yihua, Stahlwer... I would bet they all came from the same OEM. There are links to the spares on the BST863 thread. A link to that thread is at the beginning of this thread.About avoiding warranty, all I could say is Apple tried to do it to me in 1998... My really expensive brand new G3 PowerBook got all the paint scrapped where it rubbed against the strip that held it in the briefcase, so I complained. Answer: You should have used an Apple briefcase, so, no warranty. Reply: wait a minute, this is an official Apple store, why didn't you provided me with an Apple briefcase? Answer: Apple doesn't make any briefcases... I fought my way through secretaries with refractory skull, deal propositions and threats until I got a replacement... but after that, nothing about seller trying to escape from warranty responsabilities would surprise me.Edit: fan is a moving part, it isn't? This non-working fan was the reason why heather got red hot and melt. Now it's working fine, but I would say these fans should be watched closely.Fellow forum member mastershake reported BST863 mainboard is crap, something about tracks breaking from the substrate while repairing IIRC. There is an open source board replacement from another forum member (see BST863 thread), which I got, so I have now a spare mainboard for the station that came DOA. But since there are no moving parts on that board, 7 year warranty should be good.

content: Quote from: tatel on May 22, 2023, 01:52:22 pmI terms of fan, cant say anything. Visually its smaller then Quick, Best, Attens, etc. So this made me doubt it provides 120L/min. In terms of motor, according to its marking taken from the video of Yihua 993 posted above its really brushless, plus reviews on aliexpress for Yihua 993Dm II are really positive, but I think those reviewed never got a chance compare to even Atten 862. In terms of nozzles they should fit like it states on Yihua Official store at aliexpress :https://www.aliexpress.com/item/1005005253381888.html?pdp_npi=3%40dis%21USD%21US%20%2432.00%21US%20%2430.40%21%21%21%21%21%402101efeb16845174078161674e679e%2112000032370863327%21im%21%21Keep it in mind that Quicks, your Best's handles are even different in thickness than Atten 862 and nozzles from Atten wont fit mentioned. So same comes to Yihua I guess.Warranty I dunno, the Stahlwerk man on email assured me its 7 yrs. Will they try to avoid it? who knows? the only thing is the station as for an Irish VAT payer would cost me 112 euro posted to my doorstep, which really tempting, oh yeah plus have to care to get angled nozzles if go for it.

content: Thanks for the corrected post. So I chanced my arm and emailed again Stahlwerk fella in order to find out if heating element is could be replaced from Yihua and if he doesnt know refer me to one from tech.support. And heres what he repliedQuoteAnother words, we wont tell ya whats inside, but you can count entirely on our 7 year warranty. I wish I have few pics of the station inside but alas. Presume, its should be better assembly inside considering position itself as a EU market product with all EU regulations etc. But its only my assumption.On another hand, Atten 862 posted from Germany for me as VAT payer is 172 euro. So now its dilemma: probably less quality and less thermostable Yihua clone with 7 yr warranty or more advanced station with virtually NO warranty but with extra pros60 quid is not a big deal for me, but considering that I use hot air couple times a month, God knows maybe its better to try up with this german apparatus and get some flux and solder spares on change )))With Apple its strange situation. My co-worker got recently Jonard Tools US company's RJ45 pass through crimper. The pass through blade got blunt in about 40-50 connectors done however it was given warranty for 2000 cuts. He wrote JT support crowd with te problem, and they instead of spare blades sent him brand new crimper worth 70 euro )) So you never know.

content: Fan is the only moving part and I'm pretty sure you could find spares on Ali if necessary. Moreover, even if fan it's a moving part, they are legally compelled to give yo 2-3 year warranty covering that part anyway. Giving 7 year warranty isn't as easy as giving the usual period and shows self-confidence.So I would go for that cheap station, particularly if you don't plan using it every day. But only you can make that decision

Which is why I would interpret the explicit limitation of the warranty to welding equipment etc. to imply that it doesnotcover soldering equipment.I don't know how your exact email exchange went with Stahlwerk. I understand that two separate people were involved on their end, and could imagine that the fact that your question related to OEM soldering equipment was lost in the process. Better ask them to confirm explicitly whether the warranty covers the soldering stations. And maybe include a link to their warranty conditions, asking them to clear up the apparent contradiction.

content: Quote from: ebastler on May 24, 2023, 08:47:51 pmThere are some exceptions. For example, their soldering flux, while labeled “solder paste flux”, then says “smooth welding surface” on the tub in English (while in German it correctly says “glatte Lötfläche”). The remainder of the English phrases on it are not much better. (For example, “gute Benetzung” means “good wetting”, not “good immersion”, which is kinda nonsensical.)Of course, the fact that it doesn’t say what type of flux it is, other than “corrosion free” and “neutral pH” would make me leery of using it anyway.

content: I couldn't resist by that price and have bought a HES-1000 ST from Stahwerk. I can confirm that it is 100% a relabeled YIHUA 993DM II. No need for more pictures, it is actually 100% the same. Nothing wrong with it, it works very well. Date of manufacturing is 2021, according to the label on the backside. Maybe they want to sell out their stock. I assume that did not sell very well, nobody expects this tool from this company, their core business is totally different.

timestamp: June 03, 2023, 08:55:59 pm
content: Hi, it is not easy to measure the temperature with a thermoelement. It is highly depending from the airflow. But all in all the temperature seems stable and is close to the temperature shown on the display when the thermosensor is approx. 10mm in front of the nozzle. For me it looks ok after a short test. In practice it works very well, I am very satisfied with this device.There is no huge EMI filter inside like in the Quick station. Why should a hotair blower need a huge EMI Filter? When it switches the heaterelement in the zero crossing of the grid power I see no need for that. There is only a X capacitor, that´s the hole EMI circuit.

content: Quote from: chronos42 on June 03, 2023, 08:55:59 pmOn the good side,the thermal stability shouldn't be dependant on airflow speed. On contrary,as you change the airflow speed, the temp first has a little fluctuation,then goes back to set value in a short period of time. As to EMI: Read some review and man claimed he got interference on his oscilloscope while the hot air rework station was on (Atten 862 it has no emi filter as well) But overall, glad to hear this station is fine.

content: These devices switch 5A of mains power in a 230V grid, so there may be fluctuations in the mains power supply to your workplace. A good practice is to use a dedicated power outlet just for the hot air station and not the workbench power distribution. I can't see how this could be avoided with an EMI filter. There are a lot of nonsense reviews out there, so don't believe everything.I am not able to measure the air temperature with an simple thermosensor, that depends from so much parameters like airflow, distance to the nozzle, background (e.g. a PCB) and so on. Only important for me is that it is working very well in practical use.
