The difference between the external and internal heat of the electric iron, the selection method and the selection of power
It's really nice upstairs. I can only say that the two of them speak well, one is concise, and the two is good
External heating refers to the iron head in the heating core inside a kind of electric iron, also known as ordinary electric iron. Generally there are 30W, 40W, 60W, and so on. Welding of ordinary products, the temperature does not require any external hot electric iron.An electric iron with internal heating. The heating core is made of ceramic core. The heating core is inserted into the head of the iron. There is a single handle, there are welding platform. Heating faster than an external hot electric iron.There are many kinds and specifications of electric irons, and the sizes of welders are different. Therefore, the power and types of electric irons are reasonably chosen, which has a direct relationship with the improvement of welding quality and efficiency.
The external heating type, the internal heating type only has the heating position, and the internal heating electric iron is a hot iron core, and is passed to the iron head inside the electric iron, so the utility model is called an internal heating type. The outer heat is the electric iron heating part outside, and then passed to the iron head, so it is called "external heat". If the general welding of electronic components, you can choose 25W or 30W electric soldering iron.
