content: Greetings EEVBees:--Sometimes Teardown Tuesday is Followed by Fixit Friday. So desoldering delicate and multi-layer boards with through-hole components cannot always be safely done with solder suckers and copper braid, if repair is on your mind. My "New" used Hakko 470-2 Desoldering Tool with 802 Desoldering Gun does the job safely and easily. I could not tell you the amount of things I have broken, trying to remove components the old way. Just one or two Multi-Layer Boards not ruined by sucked out Via Tubes, and it pays for itself.--Just lower the nozzle over the component lead, wait a second or few, and Bzzurrp you have clean tinned hole, and no need for desoldering braid. You wiggle the nozzle while holding down the vacuum trigger and it cools the lead down and leaves it standing free of the pad, components usually fall right out or pull out very easily. Once you use one of these you will find it very hard to go back to the old down and dirty thoder thuker.--I managed to get mine for less than $200 on eBay. Parts are plentiful from a multitude of sources. The cost was comparable to a new Hakko 808 Desoldering Gun, with the difference being that you do not have to carry the pump and the motor to the board, just the hand piece. Also the 470 is much more robust than the 808 and even my used unit should easily outlast the stand-alone 808 Gun."T'ain't What You Do (It's the Way That You Do It)"Melvin "Sy" Oliver 1910 -1988 & James "Trummy" Young 1912 -1984Best RegardsClear Ether

content: Nice wrench mounting there, convenient and so useful. I miss the DS708 solder station I used to use, even if it was such a PITA to clean and maintain. No spare filters, so make do with clean the glass and grab some fibreglass wadding to use inside, and bought an acetylene torch cleaner to unblock the tips.

content: Dear SeanB"--Glad you like the wrench holder. They are of course chrome plated Neodymium, Iron, Boron magnets from a Western Digital disk drive, a use for which WDHDs are reliable. I decided to speed change a hot nozzle the other day and the hot nozzle got away from me and was about to roll off of my bench and into my lap. Well, priorities being what they are and Bob being your uncle, I now have a 3rd degree burn on my left hand. I often do daft things when I am in a hurry.--I am unfamiliar with the DS708. Could you please post a picture and/or link. I am just beginning to learn about high quality soldering and desoldering equipment and supplies. I have two Hakko 936s, both with the green LED On Light mod, one has a standard 907 Wand with standard issue chisel tip, and one has the 908 conversion with the biggest chisel tip for heavy duty work. And for super heavy duty work I use my new 300 Watt Weller D650 Solder Gun.--I used to assemble Heath and other kits for money, using run of the mill irons, and have developed such a light touch that now, I use the Heavy Duty 908 Wand set to 300 Deg. C, and heavy gauge 63/37 solder for all but small SMD work. I have never destroyed a component with solder yet.--I have Dave to thank for my addiction to used Fluke, Tektronics and Hakko equipment, the stuff is bulletproof. And I rather wish Dave would do an in depth Desoldering Video, with a guest camera man, so he does not have to work like a one armed paper hanger, his camera work is great but sometimes his soldering is - feh. And, I would welcome anyone's comments, or war stories, on soldering/desoldering techniques and equipment.--One of my next projects is going to be a couple of super heavy duty Snap-On 120V Welders. I may indeed need those Fluke 87 V safety measures."Wherever smart people work, doors are unlocked."Steve Wozniak 1950 -Best RegardsClear Ether

content: Weller unit that I used in the 1990's, nice, but with a price tag that would make you bleed in sympathy, even if you were not paying for it. went trawling through google imagesbut nothing found, probably discontinued in the early 1990's. It used a standard Weller heater element on the iron side, but without a magnastat and had a thermocouple in the tip. The desolder side had a similar element and used a hollow tip with the glass catch tube mounted above it. Could handle almost any job, we used it to unsolder flexiboards, where there were 21 in a stack on the backplane on pins. It also did well on non thermal relieved boards to unsolder capacitor leads.

content: I have an Ungar 4624 soldering/desoldering station. The desoldering gun looks very similar to the Hakko. Been using it for years.If I ever have any time, I'm thinking of modifying the desoldering part to maintain a vacuum in a reservoir. The pump would be controlled by a vac sensor to maintain a vac in the reservoir and the gun would operate through by a solenoid. Instant vacuum and the pump wouldn't run every time you hit the trigger.

content: Dear PaulAm & SeanB:--PaulAm, see the attached pictures. Certainly looks like a fine combination soldering and desoldering tool. There are a few on eBay right now at the below address. Do you know what this unit cost new?http://www.ebay.com/sch/i.html?_trksid=p2047675.m570.l1313&_nkw=Ungar+4624&_sacat=0&_from=R40]--SeanB, by any chance is the attached picture the one you were talking about? If so, There are a few of the for sale on ebay at the below address.http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=weller+ds600&_sop=12--Two questions; 1) Do you know how much a new unit cost. 2) What does the nozzle marked Air do? If I were not so broke, I would have bid on the one that is at $50 right now.--Also, there is the Denon DN-SC7000, which is used by Norcal715, who does great all around electronics repair videos. He is nearly as good with a camera and mike as our own Dave Jones, but no Engineering, just Repair. The DN-SC7000 appears to be similar to the Hakko 808 and is priced £335.20 by eBay UK, and may be superior to the Hakko 808, for all I know. If anyone is familiar with the Denon DN-SC7000, please chime in."I wear suspenders and a belt. I am a security man all the way"Justin Wilson (The Cajun Cook) 1914 - 2001Best RegardsClear Ether

content: Re: 4624I have no idea of the original list, it's been out of production for years now. A complete station with iron and desoldering gun sold on ebay the other month for $86. I think I paid $50 for mine at a hamfest. I should have bid on the ebay one. I can find tips, but replacement irons are difficult to find.I'd probably look at an Aoyou now; they look like a fairly good value for the money.

content: That DS600 is similar, but probably a later model. The air outlet is probably for a hot air head that is similar to the suction one, but which allows hot air rework.
