How to fix an electric soldering iron's broken electric heating wire
The electric heating wire of the electric soldering iron is broken. Two treatment methods are given here. The simple repair method is to splice the fracture. The fast and reliable treatment method is to take the heating wire out of the barrel, first remove the oxide near the fracture, and then tightly Splice. Treatment method for broken electric heating wire of electric soldering iron
The common fault of electric soldering iron is that the heating wire is broken.
1. Simple repair method: Splicing the broken parts, but after this connection, sparks often appear due to loose joints, and the joints break again after a short time. Recommendation: How to use a soldering iron?
2. Quick repair method: take the heating wire out of the cylinder, first remove the oxide near the fracture, and then splice it tightly. : 1 ground), after installation, power on for a few minutes, the powder will melt and adhere to the contacts. In this repair, the contact will not spark, and it is also more durable.
There is a fast and reliable repair method: take the heating wire out of the barrel, first remove the oxide near the fracture, and then twist it tightly, and sprinkle a little mixed powder of glass and electric porcelain around the joint after twisting (mix the two Grinding according to 6:1), after installing, power on for a few minutes, the powder will melt and adhere to the contacts. In this repair, the contact will not spark, and it is also more durable.
Reasons and solutions for soldering iron tip not sticking tin
Exposure to organic matter such as plastics, lubricants, or other compounds. The customary approach:
It is to use a knife to scrape off the oxide layer of the soldering iron tip to expose the copper that has not been oxidized by air. Then, put it in the rosin box and dip it, then dip it in tin, and it can be used normally. However, this method does not remove it completely. At the same time, if it is scraped off for a long time, the tip of the soldering iron will become thinner and affect heat transfer, resulting in a drop in temperature and even damage to the tip of the soldering iron.
A quick and efficient way to do this is:
Holding the wooden handle of the electric soldering iron, immerse the oxidized soldering iron tip in a container filled with alcohol, take it out after 1-2 minutes, the oxide will be completely and cleanly removed, and the soldering iron tip will look brand new. This is because after the copper oxide and alcohol are heated, a chemical reaction occurs, and the copper is reduced, which has no corrosion effect on the tip of the electric soldering iron.
