Constant temperature soldering iron (electronics related)
A constant temperature soldering iron is an electric soldering iron with a constant temperature device inside, which can keep the temperature of the soldering iron within a certain range, which is different from a low temperature soldering iron, which does not have a constant temperature device. The type and head of the constant temperature soldering iron are more likely to be damaged. *Wattage is usually used to indicate its heat. Common ones are 20W, 30W, 40W, 50W and 60W, etc. The higher the wattage, the greater the power consumption and the hotter the tip of the soldering iron. As far as vacuum tube circuits are concerned, since the contact area to be soldered is usually not small, a soldering iron of 40 watts to 50 watts is more suitable. In addition, there is also a two-stage soldering iron on the market now. It is relatively small, such as 15 watts, but when you need high temperature, it provides a button that can be pressed to heat with a higher wattage, such as 60 watts. Usually this kind of instant heating has a time limit. If the heating exceeds the time, it is easy to damage the soldering iron.
