Soldering help?

I have trouble getting the solder to actually stick to the things I'm soldering. I use flux, but all the solder sticks to the tip. I have to keep making a bigger bubble until it falls off onto the wires. Am I doing something wrong?

type of soldering wire use

Hello, I have a 60/40 rosin core solder wire. Then I use a 220V soldering iron. Now whenever i tried to melt it, it took short while. compare to those wire in which you can melt it by only touching it with the iron. It's because i tried to repair a headphone jack and I still got where to solder it. Top - Green 2nd - Blue 3rd - Copper  4th - Red It was based on its current solded positions between the thin wires and the 3.5mm jack. now I'm asking what kind of wire do I use. I saw other video tutorials on how to repair a headphone and whenever they solder it, it was a spot on. Thank you.

Soldering copper question.

I'm working on a project that requires soldering a 1/4" OD copper tube into a hole drilled in the side of a 2" copper pipe. Will a soldered join (not brazed) be sturdy or do I need to do something to reinforce (cut threads into the tube and pipe, flare the tube and insert from inside, etc) it? There won't be a lot of stress on the join but there will be a small tap on the tube to there may be a bit of torsion now and again. Thanks for your responses!

Solder types (electronics), some good info on the topic

This thread on stackexchange gives overview of different solder and flux types, what to choose as beginner hobbyist and some points on health risks. The answerers do not agree on everything, but despite that there is lots of quality information gathered together. Maybe good to refer to, when some part of the topic comes up in questions section some time again. Enjoy.

How to Break Solder Tabs On Ni-Cad Battery Pack

So, in a fit of optimism I decided to rebuild a Ryobi One 18v battery pack for my drill. The task seems rather straight forward except that I can't gracefully remove the soldered tabs on top of the batteries that actually make the circuit and connect to the wires.  In the past, I would have removed something like these tabs by either holding the soldering iron to them to melt the solder, slicing the solder with a razor or a combination of the two. These tabs, however, are seriously attached. They won't pry or slice off and the metal of the tab begins to melt before the solder does if I try the iron. I think anymore heat will damage the battery themselves.  Now, it's been a while since I did any electronics work but after a couple of tries I remembered which end of the soldering iron to pickup. I don't think I missed anything. It just seems like these tabs aren't attached with run of the mill solder.  Has anyone had this problem (and found a solution) or am I just missing something blindingly obvious?

I got a new PC board from radio shack and I am going to be making a little flashlight.  I don't think the board is interconnected in any way, so is it ok for me just to use melted solder as a lead from one spot to another, like connecting the pos and neg of two led's.  If this isn't right, what is the proper way to use those PC boards.

Will solder conduct electricity between two leads even if the leads are not touching? Answered

I recently moved from a prototype to soldering the components. This is a very compact application, and I'm thinking some of the leads are not actually touching (which is why it isn't working), but the solder still provided a strong bond. Should the leads always be touching in order to eliminate a poor (or no) connection? Also, would it be poor practice to use a small snippet of 20 gauge wire as a "crimp" over two leads to ensure connectivity, or would this only complicate matters? Thanks!

:O I soldered something! Thank you instructables!

Okay. This is stupid. But I did it! I, me, Lithium Rain, soldered something - and it isn't teh failz. It works.It works.IT WORKS PEOPLES!I have attempted for three years to teach myself this skill, and failed badly every time. But I did it this time! A whole new world is mine. All those instructables I looked at and sighed with resignation that I would never be able to do - I can try them. All the broken earphones - I can fix them. All the little things that would have been so much easier - I can do them!And instructables is why. It sparked my initial interest and all the awesome projects and users motivated me to keep trying even when I was melting humongous blobs of solder into a big mess, and giving myself cancer from breathing the fumes, and burns from hot metal and solder, and a complex because I couldn't solder two dinky little wires together. Thanks, instructables!Okay, so it's not that big an accomplishment. But it made my day!

Adjustable solder iron

Hello sorry if this is the wrong place, i'm pretty new here. recently i got a 30w solder iron and found this instructable to make it adjustable I know it won't be as good as buying a real adjustable iron but this is cheaper and will work.  I have a little potentiometer that i got from a lamp but unlike most it only has 2 terminals and a space for a third. i did some experimenting and it seems to work fine, the 2 terminals are a middle and one to the right then a space to the left i hooked a wire in the space and it basically worked in reverse to when it clicked off it turned the (in this case) motor. so my real question is how do i wire this up, can i just wire the "hot" wire threw the pot and will it work to make my iron semi adjustable the only info i have on the pot is that on the top it says B500k i can take a picture of it if needed.

Building a hair thin Mini hot tip (like soldering)

Building a hair thin Mini hot tip (like soldering) Building a hair thin Mini hot tip (like soldering) Well as you read it I am trying to build a very very small heat controllable mini hot tip (max 40 degrees C) And definitely I am sure you are such an expert in the area that the hair hot tipwill sound like a joke to you. What for? well, long story short I want to put bacteria samples on it & gradually increase the temperature and see how the populations die or survive, and most likely how long they last, to demonstarte if actual dishwashers do a good job. (maximum temp boiling point) I actually want to record the video given to the fact that the microscope I have access at school is wayyyy more powerful than the rest. I know I should use an LED or just heat but what prevents me from doing so is just blowing away the samples from the tip or changing the exposure too much with extra lights. I believe the principle is almost the same as with the coil inside electric bulbs or the same as in ironing clothes but not as hot (in orders of magnitude) I believe the trick is driving voltage and just making variations to it with a dial please help I really want to see those bacteria and film them . All help will be appreciated Thanx Micro Freak apprentice

Solder sucker?

Hello all.  I had a question about desoldering.  First thing is that I have desoldering wick.  I found out I was using it wrong.  I melted the solder and then placed the end of the wick in the melted solder.  But I watched a youtube video and according to that I should place the wick on the solder and then heat up the wick and solder as one.  But this still has not been working very well for me.  The wick is over a year old and I was wondering if this could be a problem.  But my other question is how well do those spring loaded solder suckers work?  I was thinking about perhaps ordering one off of e-bay.  Yes I know I might find one in a good hardware store but I have some paypal money I could use.  In case you do not know what I am talking is the spring loaded suckers where you cock it, put it next to the melted solder and then press a button and it forms a vacuum and sucks up the solder into it.  I think I can pick one up for a few bucks off-line, so if you people say they work well then I will give it a shot. Also in case you want to know what I am working on.  This would be used for salvaging parts of of circuit boards.  Like right now I am trying to salvage a few capacitors and also a couple of flyback transformers from crt computer monitors.  Also tomorrow I am tearing apart a broken water cooler to see if there is anything I can take out of there. I have also being having a problem getting solder to melt in the first place.  But that probably just has something to do with the 2 soldering irons I am using and I am trying my best to figure it all out.  I know my way around computers as far as building and repairing them.  But soldering and desoldering is something I really want to learn to be able to further my computer repair skills.  Sometimes it would save so much money being able to solder and desolder myself.  Especially those darn ac ports that are soldered right onto the boards sometimes. I have not actually made anything from this site yet.  But this is a wonderful site and after cruzing the forums here I am pretty sure I will get some good replies.  Ok I will stop babbling and I look forward to your replies.
