The surface of the solder on the connection you are soldering should be bright and shiny.
A cold solder joint will not be shiny, it will have a crinkly look about it. In some cases the joint can be wiggled and it will come apart.

What is meant by tinning stranded wires?
It is a reference for the preparation for soldering a stranded wire so you get a good joint. You twist the strands together, heat the wire with a soldering iron or gun and then apply a small amount of solder on the tip of the wire and it melts into the strands. Then you can solder the wire to another like wire or to a terminal or whatever. You basically reheat the wire to make connection and can add more solder as needed.Additional informationTinning is also useful if the wire is to be put in a "screw lug". The term "tinning" comes from the fact that older solder contains lead and tin. Some of the newer solder is supposed to be lead free.
How do you solder?
Step 1) Twist the two parts together (only do this if you are soldering two wires together).Step 2) When the soldering iron is hot enough, tin the tip of it with solder or tinning compund.Step 3) Heat the parts that are going to be joined. DO NOT MOVE THE SOLDERING IRON.Step 4) Slowly push the solder into the heated area. Sing 1 2 3 4 5 once I caught a fish alive while you are doing this. This is becuase when you finish singing it, enough solder will have melted onto the joint.Step 5) Clean the tip of the soldering iron by rubbing on a damp sponge.Step 6)Leave the solder to cool and harden.u have to use the right type of metals but for like wires u would twist the two together like _ _ not like /\ under a wire nut and use a soldering stick to heat up the exposed part of the wire and brush the solder across and it will melt on it and down into it== ==Use the soldering iron to heat both the solder pad and the parts lead at the same time. Give it a couple seconds to heat up and then apply your solder, using just enough to cover the soldering pad and connect to the wire lead. Then let the connection cool. Be sure that the part lead doesn't move during the cooling phase or you'll get what they call a cold solder joint. It takes a little practice but it's no rocket science, either.The solder should be a `rosin core` solder. What that means is that the solder has soldering flux built into it which helps clean the connection after being heat activated and also helps to ensure that the solder will flow evenly as well as adhere to the metal.A cold solder joint looks grainy and dull in appearance. A good solder joint looks shiny. If you get a cold joint, reheat it and let the solder cool down again, and if necessary, it's OK to add a touch more solder.
How do you fix the odometer display it only works intermittently and the Tachometer seems to be connected to the same circuit in a Chrysler Sebring?
there is probably a broken solder joint on the instrument cluster circuit board. if you look at the circuit card itself there will be 2 resistors that look burned. by them there is a solder joint that connects the front and back of the board. check to see what side is not making connection and add solder to it. it takes a couple hours to do, and the solder job doesnt need to be perfect.
Is it safe to solder inside?
Yes, usually no problem. If you know how to solder, then solder away.
Is flux in solder?
In some solder it is. But even if it is in the solder you should still use flux.
How can you solder back on the power adapter piece that broke off?
This also happened to me with my Dell Inspiron laptop. The piece inside that makes the connection is called the Dick you just have to solder it back on. Good luck!
Is soft solder a good conductor of electricity?
Yes: flux core solder is. No: acid core solder is not.
What points on the back of the instrument cluster do you need to solder on my 95 neon?
Solder all the pins connected to the two large plugs, there is about 20 or so connection, just solder them all on the back of board.
What is rosin core?
Rosin core is a type of solder that incorporates a rosin that is used for a flux. The rosin is in a central core of the solder and when the solder melts the rosin cleans the metal of oxides to make a strong and clean connection.
What are the characteristics of series connections?
Characteristics of parallel connection.
How would you solder a fusible link?
You wouldn't -- fusible links are designed to melt and break the connection when they get hot. You'll need to crimp the connection.
What is flux remover?
When circuit boards are assembled, the parts are soldered on. In order for the solder to make a good connection to the parts and to the board, a substance called flux is mixed into the solder. It removes oxidation and cleans up the surfaces of the different parts so that the solder can stick to them. After the board is assembled, there is still flux on the board. Flux remover dissolves the flux and washes it away.
What is soldering?
According to Wikipedia:"Soldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint, the filler metal having a lower melting point than the workpiece. Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the workpiece metal does not melt. Formerly nearly all solders contained lead, but environmental concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes."Soldering is a process whereby two or more metal parts (wires, component leads, pipes, etc.) are joined by the melting of a metal between them. The melting metal is known as solder. Traditionally, it was usually composed of an alloy of primarily tin and lead, but due to current environmental regulations, the use of lead in solder is becoming rare. In common useage, the phrases "solder joint" and "solder connection" mean the same thing (see below), and are used interchangeably. The word "connection" by itself can refer to either a "solder connection" or to the metal parts before they have been soldered. Confused? It's gets easier when you look at how the word or phrase is used in a sentence... as follows. The soldering process requires the heating of the parts of the connection to "wetting" temperature, the temperature at which the solder will chemicaly alloy with the metal parts being soldered. This temperature is dependant upon the alloy of solder that is being used; with " traditional" alloys, it is approximately 500 degrees F. Current no-lead solders require considerably higher wetting temperatures. In either case, if "wetting" temperature is not reached, when the solder is applied to the connection, it will melt and flow onto the metal parts, but will not alloy with them, thereby causing a "cold solder joint". By the way, cold solder joints are NOT usually dull and grainey. Dull and grainey solder joints are overheated. Cold solder joints appear uneven and lumpy, and lay on the surface of the connection like water on a waxed car hood - the solder does not flow out smoothly. Depending on the application, the heat required to make the solder connection can be provided by a soldering iron, a solder gun, a torch, or a hot-air gun. Other methods exist, but are usually used only in automated processes. When a solder connection has been made properly, the connection is solid metal; there is no barrier or space between the parts of the connection. Essentially, the solder has blended with the parts of the connection, forming what is called an "interrmetallic alloy". The intermetallic alloy forms where the space between the parts was before the soldering was perforrmed. Without the formation of the intermetalic alloy, a true solder connection has not been created; what would exist would be "encapsulation" or simple "adhesion", but not a solder connection. This type of metal-to-metal connection is mechanically weak when comaperd to a solder joint, and will not provide the long term reliability and low electrical resistance that a true solder joint will provide.Soldering is a process whereby two or more metal parts (wires, component leads, pipes, etc.) are joined by the melting of a metal between them.

How to remove solder?
Solder has to be heated in order to melt it for removal, usually by a soldering iron. Then the removal methods can vary. You can get a braided solder remover from a local electronics store that when applied to the melted solder will "wick up" the melted solder. Then there's the vacuum bulb or vacuum hand held solder pump that is used by placing it on the melted solder and either by releasing the bulb or tripping a lever, will literally suck the solder from the connection. Soldering is easy to learn but there are pitfalls if you're not familiar with the techniques, proper sizes of soldering irons, etc.
How do you fix a broken wire connection on a coil from my tattoo gun?
If it is a broken conductor connection, you can solder the connections. Someone please add some more, this is not a complete answer.
