Method of repairing broken electric heating wire of electric soldering iron
There are two ways to deal with the breakage of the electric heating wire in an electric soldering iron. A simple repair method is to twist the broken area together. A fast and reliable solution is to take out the electric heating wire from the cylinder, first remove the oxide near the fracture, and then tightly twist it together. The treatment method for the breakage of electric heating wire in electric soldering iron
A common malfunction of an electric soldering iron is the breakage of the heating wire.
1, Simple repair method: Twist the broken part together, but after this connection, sparks often appear due to loose contacts, and after not using it for long, the contacts break again. Recommendation: How to use an electric soldering iron?
2, Quick repair method: Take out the electric heating wire from the cylinder, first remove the oxide near the fracture, and then tightly twist it. After twisting, sprinkle a small mixture of glass and electric porcelain powder around the joint (ground them in a 6:1 ratio). After installation, power on for a few minutes, and the powder will melt and adhere to the joint. By repairing in this way, there will be no sparks at the contact point and it is also more durable.

Selection of electric soldering iron
The power of an electric soldering iron should be determined by the size of the solder joint. The area of the solder joint is large, and the heat dissipation speed of the solder joint is also fast. Therefore, the power of the selected electric soldering iron should also be higher. The power of a general electric soldering iron is 20W, 25W, 30W, 35W, 50W, and so on. Choosing a power of around 30W is more appropriate.
After prolonged use, a layer of oxide will form on the tip of an electric soldering iron, making it difficult for it to eat tin. In this case, you can use a file to remove the oxide layer, turn on the soldering iron, and when the tip is slightly hot, insert rosin and apply solder to continue using it. Newly purchased electric soldering irons must also be tinned before use.
