Adjustable 50W 110V Soldering Iron 2163

by rickm45 on Wed Nov 26, 2014 1:52 pm

What is the standard tip supplied with this soldering iron? With Atten or Hakko # would be helpful. I am assuming a Atten 900 T-1.6D = Hakko T18-D16 but I could be wrong on that.

If this is a general purpose tip, what is a recommended additional tip from Adafruit? Probably smaller, better for occasional SMD work? This is for occasional use, primarily thru-hole, very occasional SMD.

Thanks, Rick

You're probably right about the standard tip, but I'll have to check on that.
I'd think the T18-S4 would be a good alternate choice for SMD work, but probably not so good for thru-hole. You'd want to switch back and forth.

the tip is a conical one, its actually pretty good for both THM and larger SMT. for fine SMT you'll need something like

I ordered this iron just a few weeks ago (on 2/20) and it no longer seems to be available now.

The tip seems to have gone black very quickly, despite never leaving it on for any longer than I was soldering (never for more than 20 minutes, I would imagine) and using a damp sponge to clean it at the beginning and end of my sessions.

It now conducts heat at the recommended temperature extremely slowly (at least 5-10 seconds to get any solder to wick) and doesn't seem to be amenable to tinning.

Is this a problem with the product, and if so, could I get a replacement? Is there a way to fix these problems?

I've had much better luck with the Hakko Brass Sponge than with a wet sponge. You should clean the tip frequently while soldering, not just at the beginning and end of the session.

If the brass sponge alone doesn't resurrect the tip, you might try the Weller tip tinner:

What temperature are you running the iron? You should leave a coating of solder on the tip when you are done using it for the day and something like Tip Tinner might help.

When I was using lead-free solder, I was running it around 400-420; now I am using lead-free and running it around 350-380. I do clean the tip frequently while soldering and have throughout; sorry to not mention that.

I tried tightening the tip as a colleague suggested. I have bought tip tinner and tried it earlier today, but it doesn't seem to have any effect like the one here in the third picture: https://learn.adafruit.com/adafruit-gui ... reparation

Instead, here is the effect I get - basically just little dots on the end, whereas my impression is that it should be coating it in a liquid-like fashion... I get the same effect at the lower and higher temps noted above.

It may work a little faster than it did before I tightened/tinned, but it still takes 3x-4x the speed shown in the demo videos on soldering - there's no appreciable "wicking" visible after 5+ seconds, although if I hold the soldering iron directly to the solder, I do eventually get results... I'd be happy to take a video to demonstrate.

Is this a problem with the iron? I am slightly concerned that it was taken down from the product listing just a few weeks after I ordered it, given that I'm having such frustrating results with it (which is starting to cause fairly serious delays in my PhD work, since soldering some of my components is the critical step and I am working alone on this part as the only engineer).

Can I get it replaced, or get an alternate tip [first] if that is possibly the problem? Please let me know if I should be corresponding by alternate channels if so.

Thank you.

Ours is still nice and clean. lets get you another tip, pick out a hakko-compatible tip
https://www.adafruit.com/search?q=hakko ... ng+tip&b=1
and email support to get that one sent to you

Hi MM, mention was made of leaving the tip tinned when you park it in the stand. When we don't tin an iron, it blackens just as you've experienced. I'm not sure if you clean it and just leave it that way in the stand … so please excuse me if this seems obvious. It is a common mistake even among professional technians. Having soldered for decades and leaving a wake of many miles of melted solder, I've learned to never, never (did I say never?) wipe the tip on the sponge and then park the iron without tinning --- not at the end of a session and especially not during use. Cleaning the tip is really part of the tinning process - it removes toasted rosin, slag, and debris for the specific reason of improving the heat transfer to allow proper tinning. And proper tinning means complete coverage of the tip with fresh solder, with no air or slag pockets, A well-tinned iron then transfers the heat most effeciently to the work.

It's easy to get the maximum life from a tip by following a simple rule - it becomes rhythmic, second nature:
- every time you grab or park the iron: sponge wipe and then tin.

Good morning,

Happily, I was able to use this advice very productively for the last year or two with my last two tips (using it at the temperature mentioned, using a brass sponge and/or wet sponge, tinning whenever it was parked or removed from the stand). I have not had problems with my previous tips, but I switched to a new one this morning and almost immediately started having issues.

After a 10-minute soldering session with leaded solder, I noticed the following appearance (first two pictures are tinned, third is not to show the blackening on the side - I noticed some on the tip as well but that seemed to go away).

I am happy to take any further suggestions, and was wondering if I could possibly get a replacement tip? (I have ordered $700 of materials in the last year or so through my lab and am generally extremely happy with your products, by the way! I really appreciate your fast customer service as well.)

Thank you!
- Miriam
