The soldering iron head is the heat conducting part of the welding table. It mainly consists of four metal materials: copper, iron, nickel, chromium and tin. Copper, as a heat conductor, is the main component of the soldering iron head. About 85% of the soldering iron head materials, copper has good thermal conductivity, which is conducive to the rapid heating of the soldering iron head. Good soldering iron heads
