  1. Turn the soldering iron on.
  2. Clean the surfaces to be soldered. Any tarnish will make a bad joint.
  3. Put the two things you want to solder together.
  4. When the iron is ready, place it on where you want to join the two

    objects.

  5. Slightly tilt the side if the point of the iron up, enough for the solder to fit in, and feed the solder in.
  6. Keep hold of the two objects until the solder is cool, otherwise the will just come apart.

How do you use a soldering iron?

To use a soldering iron, you must have a piece of solder, something to cool it down, eg a damp sponge and a mains plug socket.You must plug in the soldering iron and push the switch. Then, you must take your piece of solder, and with the soldering iron in one hand (Preferably your strongest hand) and your piece of solder in the other, you need to heat the tip of the soldering iron by feeding your piece of solder through the curved part of the soldering iron. This will melt the tip of the solder, and once you have melted about 5 millimetres, you are ready to go.You need to use your piece of solder to feed through the soldering iron once again, but this time, the melted solder (the gooy gray stuff) that comes out needs to be applied to the two pieces of metal you want to solder together. Once you have used about 2 centimetres of solder, the melted solder will have hopefully made a mountain shape that curves around the two pieces. Solder freezes VERY quickly so you only have to leave it for about 5-10 seconds, then give it a firm pull, and it should remain intact.ANSWER: The sponge is not to cool it down but rather to clean the tip from operation to operation. To begin with apply solder to the tip to tin it. Always use the right iron for the job. The idea is to melt the solder and make a good connection without heating and destroying the part. A good solder connection is a shiny connection. The application of solder flux will help the solder to flow and displace material present. There is no time limit or set time if it takes too long you got the wrong iron needs more heat in that case or a clean tip.prepare the items to be soldered so that they make a solid mechanical contactclean the surfaces with flux (if you are using "cored solder" this happens automatically)begin heating the items to be soldered with the soldering ironmelt a little bit of solder between the soldering iron and the items to be solderedas soon as the items to be soldered are hot enough to melt solder themselves melt solder into themimmediately remove the soldering iron and let the joint coolif the joint has smooth shiny surfaces you are done, otherwise the joint will be rough and crystalline looking (this is called a "cold joint") and you will have to apply more flux remelt it with the soldering iron and sometimes add a bit more solder. oddly enough a common cause of "cold joints" is overheating and burning off the flux you applied


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.

Why do you need to tin first the wire before soldering it?

pre tinning make it easier to solder wire because the solder is already " stuck" to the wire. and less solder will be needed to join the wire. if you watch the solder under a magnifier while tinning, you will notice the solder does not flow and "stick" until proper heat and flux ar applied. this heat usually is more than required to melt the solder because it takes mor heat to heat up the wire due to higher density. after tinning, less heat is required to melt the solder, and enough flux is usually left from tinning to quickly join the wire to the desired material provided the material is also tinned. this reduces cold solder and provides for a more relible connection. To tin the wire first is to cover the end of the wire with a layer of solder before you put it thru the hole in the PCB that will give you insurance of a proper electrical contact else you will put a heap of solder on the PCB without a proper contact with the wire itself what is called a dry joint that go for un tinted copper wire only normally all electronic component pins is factory tinted

A soldering iron should work if it is able to get hot enough and you have the right kind of solder. You need a solder that is made for electetonics. If you have an acid core or one used for plumbing they will not work. The iron will need to produce enough heat to get the item soldered hot enough for the solder to flow and bond.


How much solder should be applied for soldering work?

A good amount of solder is less than one drop, and should be applied through a very hot and clean gun, also making sure that you are using a new solder wire, avoid using solder from already soldered components because it will be having no zinc chloride.


How do you get a nice solder bead when soldering charms?

The key to this is to get the iron really hot. Flux the iron first, then apply solder to the iron. Touch the charm with the solder at the ready. It should bead perfectly. The other key is to work quickly, you don't want to melt your charm.

What does solder consist of?

Solder has traditionally been a tin lead alloy, but there are many variations depending on the application:jeweler's solder or silver solder, has always contained silver to prevent the solder from dissolving silver and/or gold from the item being solderedother low melting point metals are sometimes added to make low melting point solderpure tin solder is sometimes used to eliminate toxic leadetc.Solder sold in the form of wire is sometimes hollow with a core filled with flux paste to make soldering easier without the need for extensive precleaning of the work so that the solder properly wets. For plumbing purposes (where the work can be rinsed afterwords) the flux paste is acidic and very corrosive, for electronics work the flux paste is a rosin.


How is solder produced?

Solder is a lead alloy with tin. Different mixes have different melting points, and for some work, silver is also added. Sometimes for electronic work, solder is presented in the form of a wire with several cores of rosin inside it. This was first made as a large billet of solder - the size of a pot - in which several holes were drilled and filled with rosin. The solder is then drawn out in a series of rollers in the same way that other wires are made from a billet of metal. The function of the rosin is to clean the surface of the metals to be joined, so the solder may easily adhere. For plumbing use, acid cores are used, but these should never be used in electronics. yo momma!:)
