How long does the soldering iron need to be heated and continue to work without damaging the soldering iron?

50W electric soldering iron can work after heating for about ten minutes. The externally heated electric soldering iron has long service life and durability, and is suitable for continuous work.

The electric soldering iron is always plugged in when it works. An electric soldering iron works by heating wires. The electric soldering iron can only work normally if it is connected to the power supply. Don't worry that the soldering iron will be damaged if it is turned on for a long time.

Matters needing attention when electric soldering iron works:

Be careful not to touch the welding head by hand when using it, and put it back on the soldering iron frame when it is not used for a short time.

After the soldering iron is used for a period of time, it is necessary to wipe the welding head on a wet sponge.

Pay attention to the posture of holding the electric soldering iron in your hand to avoid burning the soldering iron wire.

Extended data:

An externally heated electric soldering iron consists of a welding head, a soldering iron core, a shell, a wooden handle, a power cord and a plug. Because welding head is installed in the soldering iron core, it is called external heating electric soldering iron. The core of electric soldering iron is the key component of electric soldering iron, which is composed of electric heating wires wound in parallel on hollow porcelain tubes, insulated by mica sheets in the middle, and two wires are led out to connect with 220V AC power supply. There are many specifications of external heating electric soldering iron, including 25W, 45W, 75W, 100W, etc. The higher the power, the higher the temperature of the welding head.
