Why is my soldering iron not melting solder?

Solder has a very low melting point (compared to other metals/alloys). Even a weak 40W iron should melt it almost instantly. If it’s not melting the solder, then the iron is not hot enough or even working. The thicker solder requires more heat to melt.Click to see full answer. People also ask, why is my…

People also ask, why is my soldering tip melting?The higher the tip temperature, the faster oxidation forms. Soldering at temperatures over 875° F causes your iron tip to oxidize twice as fast as soldering at 700° F. Adjust your soldering temperature to the minimum temperature needed to melt your solder and have it flow smoothly for you.Additionally, how do you melt old solder? put your iron to it to heat it up, then dab a tiny bit of new solder on it. the flux in the new solder’s core cleans the joint and helps it melt, and the whole thing should go liquidy. Secondly, what do you do if Solder won’t melt? Avoid high temperature and long exposure! Use enough temperature that lead or lead-free solder start to melt and make sure that point and area around get cooled for another attempt. Otherwise, excessive temperature may oxidize traces below soldering mask, pull it up or destroy near ICs and other sensitive parts.How do you remove oxidation from soldering iron tip? Removing Mild Oxidation Adjust the temperature of the soldering iron to a typical work range (about 300°C). Apply flux-cored solder to the oxidized tip. The heat will activate the flux and start the chemical reaction that will remove the oxidation. Use brass wool or specially designed cleaners on the tip.
