Do you have a dull soldering iron tip that just wont do what you want it to anymore? Without proper maintenance soldering tips will not last as long as they could, and the cost of frequently replacing tips is expensive compared to using all of these methods. Not sure which method to pick? Well that's what we are here to help with. Let's start with the basics.
1. Check that the tip has been installed properly and be sure that the tip on the soldering iron is securely fastened. If the tip is not secure, the tip may not be getting hot enough to melt solder.
2. When working with flux other than solder wire, avoid direct contact with your soldering iron because the acids in the flux will corrode the tip.
3. When the tip is secure and able to heat to the optimal temperature the user will know whether they are working with good or bad solder. Good solder will melt at the proper melting point whereas bad (old) solder will not melt at its melting point due to oxide build up.
