The T12 soldering iron head is a composite welding turtle. It is a complex of the three components of the heating core, the temperature sensor, and the soldering iron head, also known as the T12 welding. The characteristic of the T12 soldering iron head is: the sensor is fully ahead, the sensitivity to temperature changes is high; the heating core component is installed inside the small volume of iron head, and the heat loss is extremely small. The two major characteristics have achieved the extraordinary heating ability of the T12 soldering iron head, which truly realizes the smoothness of 350 degrees low -temperature lead welding. There are many types of T12 welding peaks, and 84 are available to choose from. (T12 soldering iron heads are except for welding, other structures are exactly the same).
