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

Explain how to apply tinning technique in soldering?

Strip the wire to desired length. Then hold the wire horizontally and hold the soldering iron underneath the stripped part while holding the solder on the top of the wire. When the wire gets hot enough it will suck the solder into the wire

How do you fix a broken wire?

The repair of a broken wire will depend on where the break is. If the wire cannot be replaced then it will have to be spliced together, preferably by soldering. The wire joint then needs to be sealed with a waterproof coating.

How to Wire Money?

If you are looking to wire money, you may find it to be sort of mystifying at first if you don't know exactly where to go or what to do. In the event that you do need to wire money, there are a few things to keep in mind before you ever step foot out the door. First, you need to know how much you want to send, and whether the company performing the wire will wire that much. For example, there are a few international names in the wire transfer business that will not wire more than five thousand dollars at once. If you need to wire more than this, you will need to wire the maximum they will allow at one location, then go to another location to wire the rest.
