soldering station with internal heating
Internal heat, as the name suggests, is "heating from the inside," and since the soldering iron head is placed outside of the heating body, heat is transferred from inside to the soldering iron head, offering the benefits of quick heating, high heating efficiency, small size, light weight, and low power consumption. Utilize your agility and other strengths. suitable for small-parts welding. However, the electric soldering iron tip's high temperature makes it easy for it to rust and turn black, the iron's core is simple to break, and the power is limited, coming in at only 20W, 35W, 50W, and other specifications.
The internal heating electric soldering iron uses a hollow cylinder-shaped soldering iron head, and since the soldering iron head covers the heating element, the heat is not easily lost to the atmosphere. As a result, the heat utilization efficiency is high, the preheating time is brief, and the power is average. It doesn't have to be too big to satisfy the standards. The average internal heating power is under 50W, and a typical electric soldering iron with internal heating is between 20 and 30W.
station for external heat soldering
As the heating resistor is located outside the soldering iron, the term "external heat" refers to "heating on the outside." It is appropriate for joining both big and little pieces. Since the heating resistance wire is located outside the soldering iron head, the majority of the heat is lost to the surrounding area, resulting in low heating efficiency and sluggish heating speed. Normally, preheating takes 6 to 7 minutes before welding. Small gadgets are difficult to solder because of its size. However, it has the benefit of having a powerful and long-lasting soldering iron tip. There are specifications for 25W, 30W, 50W, 75W, 100W, 150W, and 300W, among others.
A solid round iron column with a covered heating element is the shape of the soldering iron head used in external heating electric soldering irons. If the electric soldering iron viewed exhibits the aforementioned qualities, including the handle of the soldering station, it can be deduced that it is an external heating electric soldering iron.
