oh! you are going thru a transformer?
I bet that's it. was not aware you were 220v based and were using a 110v hakko.
very likely its the power going into it that is not strong enough and that's the dipping (and peaking) you are hearing.
Hi,
I bought the 300W transformer. It works now much better
Lesson learned: even tough it only uses ~100W, you need to have quite a bit more overcapacity, for correct operation.
It really needs a stable voltage supply.
Hy.
Thanks to this Video i bought the ZD-987 Desoldering Station from a lokal distributor. It looked much like the ZD985, only it had an aditional soldering iron.
To my shame it didn't last the first day after opening the paket.
Two things brought it down.
First the desoldering Gun itself. I tried it on an old ATX- Power supply board. I sucked on the pins of one of the transformers when the downfall began.
Some of the Solder didn't made it trough the heated part of the gun into the glassy tube witch should catch the solder and cool it down. Some of the solder just get stuck at the last milimeters into the glassy tube. I noticed it realys quick as no more air could be sucked into the desoldering gun. I could even see the tiny bloob of solder that got stucked. So began the second part of the downfall of my lovely new toy.
With the solder stucked into the end of the heated tube, i took apart the gun trying to get rid of the solder bloob when it happend. I layed the glassy tube on my bench and right in the trouble of fixing the stucked solder, the glassy tube roled of the bench onto the concrete floor. And there it shatterd into pieces. So my advice for today. Those tube is realy fargile, take care with it.
Now i must wait till the end of the month because the spare part isn't aviable right at the moment from my distributor. And to make it worse. Those glass tubes dosn't come allone. I must by the whole desoldering gun. as spare part...
Oh an a second advice i also have. It looks like those Desoldering Guns come in two different versions. With an 6 pin connector caled ZD-552 or an 7 pin connector caled ZD-552B. My one is of the second type with a 7 pin connector.
And one question i also have.. can any one give me an advice how to clean the solder from the tube ? I've tried everything i could thinks of and i don't get the solder out of the tube. Those neeldes i got with the tube aren't of any help. I tried to heat it up to just around 380 degree celcius and poked around with the needle. I olso tried ti heat it from the back with my soldering iron. But i coudn't get it out.

Hi Janaha,
Sorry to hear your ZD 987 has trouble.
In the manual of hakko I read that it's best to wait at least 5 minutes after you plugged it in.
That allows all of the heating parts to get up to temperature.
With the 300VA transformei can report the Hako 808 works fine on 230V
Hi, this question might come a little bit late and considering that I am relatively new to electronics it might even be stupid. But in minute 10:37, when you check if the tip is earthed, shouldn't you have the mains cable plugged?.
For some weeks I have the Aoyue Int474A++ desoldering station and it's performing very well.
The pistol internals looks much alike this Rhino tools thing but it does its job and that's the important thing.
As a reworkstation I use the Aoyue Int968A+, also to my satisfactory.

No real need, unless you are concerned about testing the ground connection through the mains cord.
Dave just made a continuity test between the tip and the IEC inlet ground pin. The tip ground was NOT brought through to the mains ground, but appeared to be tied to power supply common (inside the PSU).

Seems that my observation skills are lacking. I hadn't noticed where the other multimeter lead was attached. Thanks N2IXK !
Just bought a ZD985 aswell. This is supposed to be a "new batch" and the gun looks slightly different compared to daves. This aint rhino branded tho.
Yes this is a new batch. We recently bought a new spare desolder gun and looks the same. This is a better solution, it can be seen when the cylinder is full and have greater capacity. Overall, I welcome this new solution. We use 5 pieces ZD915 already 4 years.
seems like a better design. I have one with the old "dense" spring and it's surprisingly difficult to get the solder out (i have to melt it out with a soldering iron...).

Try stuffing a wad of glass fiber batting in there and see if it helps. I don't get solder on the spring and it cleans up with a pair of tweezers.
Hi all,
Just received a Rhino ZD-985 for Christmas
I can report that this upgraded unit now comes with both the dense spring and a dark colored cylinder as well as a glass cylinder and lighter spring, just like somlioy's unit.
Additional spares that come with it are 3 cylinder filters, 1 case filter and 2 additional tips.
Also the display also now has a transparent cover over it so you can't press on the LCD.
The best improvement is the heat up time, looking at Dave's video it seemed like it was taking 2 - 3 minutes to reach 300deg. Heat up time from 25 to 300deg was timed at about ~1 min 21 seconds for this unit.
Another indication that its "upgraded" is that, when power is applied, the screen flashes "u03"
One thing I'm not sure of for previous units is that this unit remembers the set temp even if power is removed from the unit.
Other than that it all functions just like Dave's.
cheers
Tim
Mine does rememberthe temperature. I think this would be seriously annoying if it didn't
I forgot to mention... the barrel is now earthed unlike Dave's unit.
cheers
Tim
Anybody here have a lead on spare heaters/entire gun assemblies for these in the US? I'd like to lay in a spare as an investment in the future. I should have grabbed one while memotronics still had the heaters in stock back in July.
Just got my ZD-915 from bourne electronics in Melbourne at the bargain price of $189. Best thing I have bought in ages! The desoldering pump works like a dream. No more burnt fingers and the components just drop off the board like Dave showed in the vid. I got a bit carried away desoldering a pcb from a old pc power supply trying all the different components. My only slight criticism is the filter in the pump seems to get clogged after a bit. Has anyone tried cotton wool as a cheap alternative to the little filter pads? Dunno if the solder might be a bit too hot for it and start to burn it? My missus was nt impressed, when I suggested I can now grab peoples electrical rubbish for component salvage.

Australia is crazy, just checked again and this model is still ~$70 with free shipping in Europe.

Where are you seeing that price?

Sorry, but you got done like a dinner sunshine, I paid $165.00 AUD from Radio Parts, who now have increased the price to $209.00 AUD and not for the ZD-915 but for the dual ZD-917, admittedly even the soldering iron sucks compared to my Weller but for what I paid (account price) bloody good value I thought.
I have posted this stuff before, your consumables, filter's, tip's, etc, are best sort from Rhino Tool's in Sydney, whom I think is actually a forum member, anyway that's where Dave got his from and that's where I get my tip's and stuff from, I'm also in Melbourne.
Google is your enemy, better the devil you dont know.

Gee, guys. He was happy before you all came along...!

Greeting's Fungus,
I didn't mean to rain on his parade, but they pay the price for not searching the forum properly, also I have my own exchange rate and my money is worth more than eveyone else's I reckon anyway.
