10 PCS Tool Bit Lead-free Electric Welding Tips

10 PCS Tool Bit Lead-free Electric Welding TipsUse and maintenance of head: 1. The head is the heat conducting part of the welding table. It mainly consists of four metal materials: copper, , nickel, chromium and tin. - Copper, as a heat conductor, is the main component of the head. About 85% of the head materials, copper has good thermal conductivity, which is conducive to the rapid heating of the head. Good heads are made of copper, but some manufacturers use br, in order to reduce costs, but also reduce the thermal conductivity of the head. , which acts as an anticorrosion, is the key factor affecting the service life of the head. Good head has fine and dense crystal structure and good corrosion resistance. This head has long service life and good tin effect. Manufacturers with poor plating technology mainly rely on the thickness of the plating layer to control the service life of the head. Usually, the plating layer is thicker and the head is not tin, thin and durable. Nickel - plays an anti rust role in plating, and is convenient for subsequent chromium plating. Chromium - non stick tin prevents the use of tin to run on the 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 com of the 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 head more durable. After use, the new tin layer should be coated only after the humidity of the so
