The heating element inside a soldering iron heats up the metal tip so it can melt solder wire. Overtime, the tip can become damaged from extensive soldering and will become brittle or melt during the process. If this happens the solder will not stick onto the iron and you can't solder things properly. So you will need to replace the current broken tip on your soldering iron with a brand new replacement tip to fix this problem. You also might want to replace the soldering iron tip, if you want a tip that is a different size, to make soldering electrical components easier to do.
1) Unplug the plug from the wall socket and switch it off. If you have recently used the soldering iron, allow the metal tip to cool down. To check if the tip is cooled down, get some solder wire and touch it against the tip. If the solder wire doesn't melt then it's cool, but if the solder wire does melt it's still hot!
2) On your soldering iron near the metal tip you will see a screw that is in place. This screw holds the metal tip into the soldering iron. Loosening the screw will allow the metal tip to free up. So using a 'Philips' head screwdriver slightly loosen up the screw.
3) Now holding the top part of the current tip, pull it upwards and it will remove itself from the soldering iron. If the tip you have just removed is broken it is useless, so dispose it into a bin. If the tip is still functional and you are only replacing it because of its incorrect size, don't throw it away because it might come in handy for other soldering jobs later on.
4) Then get your replacement tip and insert into the tip hole and push it in all the way down. Then using your 'Philips' head screwdriver, tighten up the screw you loosened earlier on. Give the metal tip a good wiggle to ensure that it is firmly in. If it is loose you will need to tighten the screw a little more tightly.
