Industrial hot air gun tells you several ways to quickly handle electric soldering iron head without Tin

Industrial hot air gun manufacturers tell you several kinds of fast processing electric iron head does not touch tin method, in our life when we use electric iron head, often appear not touch tin, tin is not smooth phenomenon, how to deal with it? As a professional manufacturer of metal welding tools, we have accumulated years of experience in Germany, the understanding of the reason why the soldering iron head does not touch tin is very clear. In addition to the quality problems, there are many reasons, such as too high temperature, easy to make the electric iron head dip into the tin surface, the use of incorrect or defective cleaning methods and other reasons.

8 causes of non soldering tin on electric iron head:

1 exposure to organic materials such as plastic, oil or other compounds.

Interrupt flux solder wire or solder wire 2 used in impure.

3 when the working temperature is more than 350 degrees, and stop welding more than 1 hours, lead tin soldering iron head is too small.

4 high temperature, easy to make the electric iron head tin surface severe oxidation.

5 tin tin is not eaten before use.

6 "dry burning" electric iron head, such as: welding table open without use, and the electric soldering iron head surface tin, will cause electric iron head rapid oxidation.

7 the use of incorrect or defective cleaning method.

8 is the use of high flux corrosive, causing rapid oxidation of electric iron head.  The use of neutral flux activity, often without cleaning tips on oxide.

Several commonly used treatment methods:

A, the welding table temperature down to about 250 degrees, put the iron head on the wet sponge repeatedly wipe, and uninterrupted new tin protection, repeat the above action until the lead-free soldering iron bright, tin on the pass. The closed iron power supply, with a blade or fine sandpaper and dirt on the surface of the tin oxide iron head, and then put into the rosin or rosin paste iron head, open the iron supply, adjust the temperature to 250 degrees, let the tip heating in rosin, and then use the solder wire for welding head on the tin. After looking for a copper tin or tin absorption line, let the tip in the copper parts of repeated friction until the solder iron has been full of entire.

B, is to use a knife to scrape off the electric soldering iron oxide layer is not exposed, the air oxidation of copper. Then, put in the box of rosin dip, and then coated with tin, it can be used as normal. But with this method of cleaning is not complete, at the same time, long-term scraping, the iron will become thinner and affect the heat transfer, leading to temperature drop, and even damage the tip of the iron.

C, holding the handle of electric iron, immerse the oxidized iron nozzle into the container filled with alcohol. After 1~2 minutes, the oxide is thoroughly and cleanly removed, and the iron nozzle is renewed. This is because copper oxide and alcohol are heated, resulting in a chemical reaction, and the reduction of copper, the electric iron head without corrosion.

Adjust the temperature of the soldering iron to 300-360 degrees, insert the special iron head repair paste, and wait for a few seconds to solder the tin with the solder wire.

The above is the electric iron head with tin solution, for your reference. Shenzhen dezhigao Hi Tech Co., here I wish you all a happy life!
