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.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
