Use and maintenance of iron head:
1. 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 are made of copper, but some manufacturers use brass, in order to reduce costs, but also reduce the thermal conductivity of the soldering iron head. Iron, which acts as an anticorrosion, is the key factor affecting the service life of the iron head. Good soldering iron head has fine and dense crystal structure and good corrosion resistance. This soldering iron head has long service life and good tin effect. Manufacturers with poor iron plating technology mainly rely on the thickness of the iron plating layer to control the service life of the iron head. Usually, the iron plating layer is thicker and the iron head is not tin, thin and durable. Nickel - plays an anti rust role in iron plating, and is convenient for subsequent chromium plating. Chromium - non stick tin prevents the use of tin to run on the iron head. The general chrome plated time is more than 5 minutes, and the ordinary decorative chrome plating is about 1 minutes. Tin - in the head, in the use of sticky tin parts. This is the composition of the iron head material, indispensable.
2. Keep welding head clean.
-Wipe the solder, tin and oxide on the welding head with a special wet sponge. After each use, it is necessary to clean the oxide on the welding head and add new tin on the tin plating layer of the welding head.
3. Keep the tin on the welding head.
- This can reduce the oxidation chance of the welding head and make the welded iron head more durable. After use, the new tin layer should be coated only after the humidity of the so
