Inexpensive Integrated De-Soldering Gun.

GA0JIE
S-993A   $99-$105 - free shipping
(Hakko, Fr-300 Clone)


473703114_546.jpg

Keep in mind there are separate models for 110 Volts and 230 volts.

here is the one that i bought.
http://www.ebay.com/itm/161413419282?_t … EBIDX%3AIT


Just got it today and did some desoldering… It is NOT as aggressive suction, as the Hakko 808.
but its about 70% as much as. Definitely lighter.

Instead of fully up to temp in 15 seconds like the 808.  This is more like 20-25 seconds.
Consumables?   Well i have no idea yet.
it has an aluminum pre filter just like the 808.
it has some kind of a filter… much smaller then the 808.
not sure where to buy the replacement filters yet.

over all impression is that it works… its pretty light…
the gun does not really fit into the stand. Its kinda of like a generic stand.
but the gun will sit in there, though kind of sloppy.

for the basic hobbyist it might be a winner.

Re: Inexpensive Integrated De-Soldering Gun.

ok so in using it last night... The more I used it, the more I realized that user fatigue is much less with this over the 808.
The 808 is a beast of a gun.

I went through a Plus AB.. and 2 SE/30 PSU's with it... 

Seem's like there was a black oxidized coating that formed right at the tip, right when i turned on the soldering iron for the first time.

I tried to Scrub this coating off with my brass tip soldering tip cleaner... some of it came off.  After the first SE/30 psu... most of the crap got rubbed
off by then...    Before this... There was an annoying delay in the solder melting.
I am not sure if there is a special coating on the tip,  If not, then i would say maybe take some emory cloth or some fine grit sand paper to the very tip first... or maybe yours, (if you buy one) wont have this problem at all.   Also once the tip got warn in right... I started to notice quite an improvement in suction, I guess, that would be natural because the solder was melting in better.

Also, The Hakko 808,  Makes a Strong, Loud sounding buzz/hum when you pull the trigger.
I have kids in the house and now, with out the Air/Conditioners running... Any Noise I make in my room, tends to resonate through the house all hours of the night.

This S-993A gun has a quieter, more muffled sound... with a lower sounding tone...   I would say over all its 25 - 35 % Less noisy when trigger is pulled.

I would also like to say that i noticed the Diameter of the heater suction path is larger then the Hakko 808, Maybe it will not plug up as easily as the hakko 808?

I have been unfairly comparing this gun to the Hakko 808 because that is all i have to compare against.

I have a Hakko Fr-300 on the way, should have it by friday.  Because that is what this ( S-993A ) is based from. ( I think )
Might be a fairer comparison between the 2?

2 more things about this S-993A...

- Heater on indicator light, Its a bright red LED, It cycles On/OFF automatically depending on the demand for heat and the set temperature.
- The Heat Temperature Pot. (Temp Labeled) (in Celsius), It's easy to adjust, when maybe going from a 60/40 job to lead free.

The 808 definitely rocks. Just a little maintenance heavy.

Re: Inexpensive Integrated De-Soldering Gun.

that might be a desoldering trait in general smile

Re: Inexpensive Integrated De-Soldering Gun.

I currently have the poor man's RadioShack Desoldering iron, which was initially a step up from just soldering iron + solder wick, although the tip has degraded significantly, and isn't terribly useful anymore.  I could get a new tip, but a common task I use the desoldering iron for is cleaning out all the filled in through holes for ROM SIMMs on systems that didn't come with a ROM SIMM slot.  That ends up being a lot for the little radio shack desoldering iron.
So, I've been contemplating upgrading.  Nearly all my desoldering work is the ROM SIMMs I described, and removing some through hole components from some of my projects, in order to recover components from failed or irrelevant projects.
I've been contemplating one of these desoldering guns, mainly due to price, and the relatively little desoldering I do, so thanks for the review!
