Cheap Desoldering Gun Options
« on: March 20, 2021, 06:10:50 pm »
Hello everybody,

As the title suggests, I'm looking if there are cheap desoldering guns that you can recommend!

I have a Hakko FX-888D so maybe there's even something that you can plug into its "base piece"?
For example, I saw online that you can buy "just the gun part" of the "Pro's Kit SS-331H". I don't know if that's an option on Hakko. It would be especially great not to have another "big box" on the table..  ;D

As per my definition of cheap? I saw the Hakko FR-301 for over 300 bucks which is like twice the price of my station so I was shocked :D Since I don't desolder as much as to justify anything more expensive, my limit would definitely be under 100 bucks for something like this.

Thanks in advance!
Dave

You could get the S-995A or S-993A from ebay or amazon (they're cheaper on ebay though) and they both have replaceable nozzles. Personally though (as one who desoldered many components throughout the years) I don't use a desoldering gun, and have no problems (it's all about the technique and the knowhow really). A desoldering gun would definitely make things easier, but one can get by without it too.

You got this one too:

Way cheaper than the other options, and appears to do a decent job (according to some Youtube reviews I've seen)

I looked at this a while ago from a similar perspective/use case, my conclusion was there are three cheap options worth pursuing.

1. Buy more solder wick, a bottle of good flux if you don't already have one, and a good sucker (edsyn soldapult).
2. Deals can sometimes be had on used pro grade stations, covid has probably upset that though.
3. Hakko FR-301

Another option some like if you're after DIP packages without destroying the chip or board is to use a hot air station. Cleaning the through holes is probably still gonna be a pain though.

Constant vacuum desoldering gear simply isn't cheap, no way around it.

For decades I've used solder wick and a plunger sucker. What a PITA! I have a 20 year old sub woofer amp I wanted to recap and knew it would be a royal PITA if not impossible to do with my limited tools. It has 6 large caps soldered to a PCB with a large ground plane. My 65 watt solder iron could barely heat it up. I broke down and bought a FR-301. Wow, so much easier to remove parts!  I have a controller board for a swimming pool heater fail years ago. The 7 segment LEDs lost some segments. I bought a replacement > $280! It failed again, but now since I had the FR-301 it was simple to remove the 28pin LED and solder in a replacement. That would be hard to do with wick and a sucker since the LED package is flush with the PCB so I can't cut off the pins like on an IC. Those 2 jobs alone paid for the FR-301. If you have one you will use it more than you think because it will be so much easier to remove parts.

I bought an Anesty ZD-915 last year. Seems to work OK. It is a huge step up from more manual desoldering methods. Looks like there are reasonably priced replacement parts available for it. I paid less than USD 150 delivered. I wasn't able to find it on Amazon or AliExpress (reasonably priced). Looks like the Pro'sKit SS-331H is the new hotness. The SS-331H looks very similar to the ZD-915. I would not be surprised if some/many parts were interchangeable.

Hi!

The SS–331 is virtually identical electronically and mechanically to the ZD–915 and Duratool clones, the difference being an updated green and black case with a different front panel layout, otherwise the tips, filters and consumables are directly interchangeable, and I suspect the heater elements are the same as the ZD–915 as well!

It's basically just "The Emperor's New Clothes" being sold for about £30–40 more than the ZD–915 series!

Banggood UK are offering the SS–331H at the best price at the moment!

It's an enigma that's what it is!! This thing's not fixed because it doesn't want to be fixed!!

Didn't you read the listing?  The new SS-331H has ""Double the effect of attracting tin"  ;)

Anyway, Banggood US has it on sale for $121, which I think is cheaper than you can currently buy the ZD-915 or ZD-8915 in the US.  It's listed as 240V, but a comment says it can be rewired for 120V - can anyone confirm?

It is quite a bit different, it is a ZD-8915 (I own one) which has a much thinner barrel and heating element with less thermal mass.
They are/were quite prone to clogging where the solder goes in to the glass tube. I did a quick fix on mine by wrapping around some 2.5mm copper wire from some scrap T&E around the exit tube to give it some thermal mass. It helped a bit but I spotted replacement guns/heating elements that looked a bit different and you can see the heater extends further towards the exit tube. I bought one and have not had a clog since.

The only problem is, if you buy a ZD-8915 or a rebadged version, there is no way of telling if it has the new style heat element or not. Though if someone was unfortunate to get the older type heater element the new replacement and replacement gun is cheap.

I was going to bin mine if the mod didn't work/hadn't got a new gun and get a the ZD-915/985 etc with the thicker heater element, but I have to say it works as well as the Weller WR3 I used at work. The big benefit of the thin barrel on the ZD-8915 is it can really get in some tight spaces.

I put a post on here somewhere regarding the new heater element/guns for these.

IIRC, I paid some €80 on perhaps last February

I have no problems desoldering parts by adding liquid flux and lead based solder to the pins, to lower the melting temperature of the existing solder  - the liquid flux also helps by attacking the oxidized surfaces and making the heat transfer from the tip to the leads.
If needed, a good solder wick helps (sometimes I dab it in flux for extra kick)

Another option worth considering is buying low melt solder, which melts at low temperature and stays liquid for a longer period of time. So you can apply this solder on all the leads of the part at same time, get both sides of a dip to be liquid solder then a small tap on the board will make the chip fall out of the board.
