Desoldering station/gun above ZD-915/474A++ ?
« on: January 15, 2022, 10:54:56 pm »
Hello,

I've been looking for a desoldering station (with sucker pump) for THT in the 100€ +/- price range.

After reading and and watching a lot of reviews, I've noticed that ZD-915/ZD-8915/474A++ kind of .... well, suck. With different design faults making them get clogged way to easily, real difficulties to open the sucked solder tank, 12V cooling fan powered at 18V and so on. Another funny thing is that the same models are sold by a lot of different brands with just a different color and sometimes just different label. I can't even find the manufacturer that makes all these white label thingies.

I guess ZD-915 would kind of work most of the time for a hobbyist, but I'd look for something better that wouldn't break the bank.

So what better desoldering stations are there in a 150€ +/- price range?

I have also been looking into this. My 9yo ZD-915 is getting a bit old and replacement tips are getting difficult to find.

Well, if ZD-915 reached 9 years it ain’t that bad. How much are you using it?

And how did you get passed that solder tank that refuses to get out? Any other issues with it?

It is not a tool i use one every 2 weeks or so on average.
Have not had an issue with it until recently when it started getting a bit random when resuming from standby temp. Probably an easy fix, just have not looked at it yet.
Have not made any mods to it at all.
The solder collection tank comes out easy enough once you get the hang of it. The trick is to make sure the small button on the rear has fully released and the rear mount is fully moved back.

Likewise, I have one too (well the Duratool Proskit branded ZD915 sold by Farnell) that I've had for several years and use occasionally. The secret is to hold the board vertically and the gun horizontally (more intuitive than it sounds). They don't clog then.

I can't remember if I did any mods, but I don't think so. [EDIT: Yes I did, I dropped the fan voltage to 12V bought a 24V fan, I'd forgotten how much it howled when I first got it! https://www.eevblog.com/forum/beginners/decent-desoldering-ironstation/msg1048746/?PHPSESSID=6c3skm4vcc6ok4tdlco065ler6#msg1048746 ]

Yes, thinking about it i do hold the board vertically when i use it, a) for easier use and b) for better light for 52 year old eyes. :) The other thing i do most times is clean it when i have finished using it. I just empty the chamber and run a cleaning brush through the nozzle ready for next use. I have done this most times i have used it and have not had it clog on me.

Somehow I clogged up the tip of a my ZD-915 once

It was a bit of pain to clean
Managed to clean it by heating it up the tip with kitchen blowtorch and poking a suitable size metal pin through the opening

The most effective unclogging method I've found is to poke a length of Copper wire through the tip and tube rather than the steel pins provided. Something like coax inner or wire stripped from some mains T&E cable. The higher thermal conductivity is much more efficient at melting stubborn lumps. For the same reason, handle the wire with pliers! The wire inevitably comes out heavily tinned - it's surprising how much solder clings to the inside of the tube without it clogging.
