Tthe art of hand soldering has been around for a very, very long time, thousands of years in fact. But it was only until 1941 that a transformer based instant heating soldering method was developed by an impatient American radio repairman who was tired of sitting around waiting for his soldering gun to heat up. Carl E. Weller had to wait until after WWII ended in 1945 to get his Weller Manufacturing Company going. In 1960, the Weller Manufacturing Co. in the US patented the “Magnastat” soldering iron which used a magnetic component to regulate the temperature at the iron’s tip. In an expansion overseas beginning in 1959, the Weller GmbH plant in Besigheim, Germany, along with new plants in other countries, was organized to manufacture temperature controlled irons and soldering guns for primarily industrial markets throughout Europe and the Near East. Keeping pace with the increasing complexity of our customers’ needs, Weller Germany became the market leader for developing and manufacturing hand soldering products worldwide. Our products were proudly emblazoned with “Made in Germany”, signifying innovation and reliability.
From the Manufacturer
The Weller WSA350 is a bench top smoke absorber that removes flux fumes from a soldering workbench. Great for workspaces using more active fluxes used with lead-free solder. Fumes are absorbed by the replaceable carbon-activated filter - includes one replacement filter (WSA350F). Stand allows the smoke absorber to be adjusted to varying angles. Fan is quiet and will not add significant noise to the workspace. ESD safe.

I was looking for a smoke absorber for some soldering I was doing. This device is simple to use, not too loud , and I have a lot of confidence in the Weller brand. It came with an extra filer as well which was nice. Great purchase.

This is a great little unit for the money!While someone who solders every day/all day (or with lead-free solder, which creates more fumes) will probably want something more powerful/bigger than this, this extractor does a fine job of sucking up flux fumes for hobby use or occasional soldering, which is more my application (I'm a soldering novice who bought it for audio electronics work). I'm not working in the most well ventilated room, and this thing does just fine keeping the air clean.It feels like a good quality, well made unit with a bit of heft to it. It's not terribly loud, but not exactly quiet either. You do need to have it fairly close to what you're soldering for it to suck up all the fumes - it won't work as well from several feet away (it also helps to point the fan inlet directly at what you're working on). So it's fine for things from quick and simple jobs up to component replacement on a smaller to medium sized PCB board.I'd say in the grand scheme of things, it's probably a 4/5 score - but I'm rounding up to 5 due to being a good value for the money IMO. Just be realistic about what a tabletop unit like this can do and you won't be disappointed.

I've used these units at work for two activities. One is the intended application of soldering. It works fine for that. The second is to remove the smell of epoxy, when potting parts for cross-sectioning. The epoxy really smells up the lab and this little guy takes care of it, as long as the mixed epoxy is placed near the air inlet/filter.This is a simple device. Just a fan and a carbon filter. Not overly quiet, but not overly loud either. It comes with 3 filters and each seems to last a while. Extra filters are pretty cheap. Nothing like a product that doesn't cost a bundle and does what it's supposed to.

I do stained glass, and when I'm working on a sizable project, I'm soldering for a good amount of time and going through quite a bit of brushed on flux. My work room is small and has just a small ceiling exhaust fan. I looked at a lot of options and did a lot of online research before buying this. There are a lot of smoke absorbers with the same 5" square filter, and most of them are cheaper than this. My decision came down to a question of air flow. This fan seems to have the highest CFM rating of any that I found. The cheapest competitors are much lower. I wanted to make sure that the fan pulled as much of the smoke as possible away from the work. I'm very happy with the result, as I never see smoke drifting toward me and can't even smell the flux being burned away.The whole device is very solidly built. No cheap parts anywhere that I can see. It should last a long time. There's nothing loose, nothing that looks like it will break or fall apart. Nice construction, and nothing that looks "cheap".Some web sites indicate that this is a "quiet" fan, which I suppose is true compared to a lot of other fans, but in my small space it's very noticeable. When listening to music, I have to turn up the volume a little. The fan doesn't screech or make any noise itself, but there IS a lot of air being moved. The trade off between a little more air noise and a lot less smoke is one I'll take every time.The mounting legs for the unit are small but sturdy, the whole fan is fairly light and easy to move with a convenient handle on the top. Being able to adjust the intake angle is great, and it's very easy with this product. I can get it fairly close to my work at a good angle and that helps keep the smoke down.The whole thing is a little big for my work area, but I can't imagine a smaller device that would do the job, so I think I've got the best possible in this regard until someone changes the laws of physics. You need a high amount of airflow, and a smaller device would have to be very, very noisy.Net result: Outstanding performance for the job, a little louder and bigger than I'd like but probably the best that can be done today. I'm glad I didn't purchase any of the less expensive competitors.

Hello,Among all orders we have purchased in the recent past, the Smoke Absorber (and the soldering device device ) doesn't work for some reason. I;m curios to know if we are missing something and how we can move forward?Thanks,Firas

Needed this fan for the pyrography projects I work on. This fan works great for this, I set it up behind the project I'm working on and it draws any smoke away.The fan is relatively quite also it is solid and the base allows it to stay in place.

Works great. Nice convenient size - my soldering space is on top of an old washing machine and this fits in just fine with an iron, and diopter lamp leaving room for the project.My only con would be it is a little noisier than I'd like, but not bad consider it contains a fan.

I was sick of feeling woozy after soldering sessions and debated between some no name models for a while before settling on Weller. Overall this did exactly what I expected and I'm glad I paid a bit more: long soldering sessions are no longer a literal headache.The unit is bigger than I expected: it's 10" tall, and the filter area is 5" x 5". The cord is 3-pronged (grounded for ESD?) and in the parlance of a popular Youtuber - skookum as frig and fairly long and surprisingly flexible.The fan has a single speed controlled by on/off switch. In operation it's neither quiet or loud - you'll notice it is on but it's not loud or annoying. It draws decent amount of air but you've got to keep it positioned ~6-8" from your work for maximum effectiveness. The fan has a wide base for stability and you can tilt it from vertical to almost horizontal and the position is held by two knobs that provide friction resistance.There's a carbon filter area and 3 filters are included.

Great quality smoke absorber. I cannot smell any fumes while soldering together with his unit. Highly recommend this brand

Wish it had a bit more power for the amount of noise it makes, but it does the job of keeping the fumes from stained glass work to a minimum.
