З різниця між внутрішнім нагріванням електричним пайкою праскою і зовнішнім нагріванням електричним пайкою праскою праскою
In terms of structure:
First of all, there is a big difference in the structure of the soldering iron tip. The internal heating type soldering iron tip is hollow, because the heating core is built-in, and the external heating type soldering iron tip is solid core, and its heating core is external.
The зовнішній нагрівальний електричний пайка залізо is composed of a пайка залізо tip, a пайка залізо core, a shell, a дерев'яна ручка, a power lead, a plug and other parts. There are noy specifics of external heating electric soldering irons, commonly used are 25W, 45W, 75W, 100W, etc. the higher the power, the the the temperature of the soldering iron tip.
The внутрішній нагрівальний електричний пайка залізо is is composed of a handle, a connecting rod, a пружина clip, a пайка залізо core, and a пайка залізо наконечник. The commonly used specific of internal heating electric soldering iron are 20W and 50W. Due to its high thermal efficiency, a 20W internal heating soldering iron is equivalent to a 40W зовнішній нагрівання пайка залізо.
Використання:
The пайка залізо головка of the зовнішній нагрів тип електричний пайка залізо is всередині the heating core, which is is also called an ordinary electric пайка праска залізо. пайка звичайна вироби, there is is no requiment for temperature, use an external heating type electric soldering iron. Since the heating resistance wire is is outside the tip of the soldering iron, most of the heat is dissipated to the outternal space, so the heating ефективність іс низька і те нагрів швидкість іс повільна. Як правило, it it takes 6 to 7 minutes to preheat before welding. its volume is large, and it is inconvenient when пайка small devices. But it has the advantage that the the soldering iron head can be used for a long time and has a large power.
Внутрішній нагріваль тип електричний пайка залізо, the shape of the пайка залізо наконечник б/уживаний in the internal heating type electric пайка залізо is is a hollow циліндр, and the heating element is covered by the пайка залізо tip, so its heat is is not easily dissipated into the air, so the heat utilization efficiency is is вище and the warm-up time is is shorter. Short, and the power generally does not need to be too large to meet the вимоги. Generally, the internal heating is is below 50W, and the internal heating electric пайка залізо about 20W~30W is common. There are single handles and пайка станції. The 936 паяльна станція is a typical internal heat soldering iron, but it is also constant temperature. Now they are all lead-free пайка праски (без свинцю станції), which are better than the previous two.
