content: I am thinking about adding a JBC DR5560 desoldering hand piece .And looking at what belongs with what - power supply etc. , I see the vacuum unit states that is requires shop air and uses a venturi to create vacuum ?Being that the vacuum box cost is significant , and it does not provide vacuum [ without shop air ] then what does it do ?I can easily provide vacuum , through my own venturi or AC vacuum pump & tank etc.I currently have a JBC soldering station , an older unit digital with the hold/stand as part of the power unit , not at my bench & do not recall the md. #ThanksI also have Metcal gear again older PS & wand , stand , also desoldering gun that connects directly to shop air .I like the idea of something smaller in the hand , but like the simplicity .

content: What's wrong with answering the question ?I can not afford to change directions after I have already started in one direction - I have a JBC base , it would cost too much to just start over .Rather than just add to what I have .I wish I could afford to try everything , but I can't .I ended up starting with Metcal [ very good deal ] - at least as far as higher end soldering gear for small electronics , I have had other gear for soldering outside of electronics .I like the Metcal for soldering , but do not like changing tips for temp , so I was open to something else , and the JBC came along at a very low cost and I like setting my temps vs. changing tips .I new of Pace , but did not come across deals like I did with Metcal & JBC .I have been buying & using tools for a long time and take the LONE VIEW on my purchases , with soldering encompassing so many aspects , I look at getting geared up as a system and at this time I see JBC filling my anticipating future needs .As far as Hakko goes , 1st thing is , as posted I wanted something smaller , the guns are just too big , 2nd starting over again , and last it seems that Hakko goes off in too many directions [ so many of there parts do not interchange ] I looked at Hakko and found it difficult to find what fit what , where as JBC & Metcal had fewer things that did not fit each other , as an example in a box of soldering gear I got mostly Metcal , there were about 20 some new in package tips from Hakko - T7 series [ now called T15 ] .Not a big deal , but I am put-off by there kiddy coloring schemes .When I got out of auto repair , I had about $180.000 + in tools -So I have to admit to having a TOOL-JONES

content: First, let me say, I have several JB stations of all types, including the HDs, and I would never go back to any other !Several months ago I decided to "update" on of my Hakko 474 (with 816/815 heads), not that I had any issues with them. I "expected" to be blown awaywith the JB ie unlimited / controllable heat etcWell, I spent the $1,500 extra, already had a few base stations, and after testing it against the Hakko, concluded that it's a POS.It sucks like a 90 old grandma with asthma, doesn't have legendary temp and power control and an annoying lag, plus there's a box of cleaning / servicingtools you need to use often. A GREAT laugh in a factory environment ! I wrote my initial results somewhere here, and was going to do an in-depth review,but was too sad. It's all in a box now, 2 hrs of use, under a bench. Pity you don't live closer.

content: A huge reason I like the Metcal desoldering gun is that its so simple & cheap compared to anything else - no special power supply and no special vacuum pump or box -[ STILL THE MAIN QUESTION HANGS - WHAT DOES THE JBC BOX DO] to maintain - just hook up to shop air [ has an internal venturi to make vacuum ] .Again the reason for looking at JBC desoldering is smaller for tight spots and comfort , it will plug into my existing PS and it would seem that if I make my own venturi or use my AC vacuum pump I good to go .And I found a $500 dollar unit for $150 , so get to satisfy my " got a good deal " also

One is an electric vacuum pump (MS version/s), and the other requires shop air (MV version/s, which are venture valves). Power units hook to them in order to control vacuum operation.Hope this clears things up.BTW, there doesn't seem to be a lot of information on their desoldering gear, but what little I've seen, it's indicated potential buyers can do better elsewhere.

content: I have a JBC desoldering system with a DR5560.There are two box types, the one that requires compressed shop air, and one with a electrical pump. Both boxes are just for suction, you connect them with a wire to the regular jbc base stations (just the ones with separate stands, not the small ones with integrated stand).The desoldering works really well for all kinds of through hole stuff. Just like with soldering you need a bit of practice with it. The most important thing is to first heat up the joint, wait maybe two or three seconds and only then press the button to activate the pump. Don't activate the pump too early.You need the suction tips matching the thikness of the leads you are trying to desolder, otherwise you don't get good vacuum. You also need the cleaning tools. IIRC they offer all theses accessories as a bundle with the DR5560, you should buy the whole bundle.

content: Quote from: KD0CAC John on October 16, 2014, 02:59:13 pmSounds like a nice project, would you mind to post pictures and build details when you are finished?Just ask if you need any details on the original vacuum sources from JBC.When you look at how JBC protects the vacuum pump from the desoldering fumes, I guess you shouldn't skimp on that aspect. They have a thick cotton plug at the end of the tube in the hand tool, a filter in the middle of the vacuum line (http://www.weidinger.eu/shop/loettechnik/jbc/jbc_zubehoer_und_ersatzteile/jbc_ersatzteile/wl22615) and another filter at the entrance of the vacuum module.

content: My intention is to use my compressor with a venturi to create a vacuum and use a separate tank for a vacuum reservoir , so no need for a filter at vacuum source .The desoldering hand piece I am looking at has the filter on the hose .Once I got it working , I will probably sell the Metcal desoldering gun .
