​The mechanical structure

External heated soldering iron by soldering iron head, iron core, shell, wood handle, power wire, plug and other parts.

Because flipping soldering iron steel-toed installed inside the heater, so called external heated soldering iron. Are key components in electric soldering iron core, it is the heating wire winding in parallel on a hollow ceramic tube, in the middle of the mica insulation, and draw out the two wire connected to 220 v ac power.

External heated electric specifications of many commonly used 25 w and 45 w, 75 w, 100 w, etc., the greater the power the higher the temperature of welding head.

Internal heating soldering iron

By the controller, connecting rod, spring clip, iron core, welding head. Because the iron core is installed inside the welding head, so called internal heating soldering iron. Internal heating type electric heating fast, high calorific efficiency, and its volume is small, the price is cheap.

Internal heating type electric backend is hollow, used for the socket on the connecting rod, and with a spring clip. Change the welding head is more convenient. When welding head needs to be replaced, you must first will spring clip out, at the same time with pliers clamp the front end of the welding head, pull out slowly, remember that not too hard, so as not to damage the link rod.

General electronic production of about 35 w internal heating type soldering iron. Of course have a 50 w external heated soldering iron can encounter. Because of its high thermal efficiency, 20 w with internal soldering iron is equivalent to about 40 w external heated soldering iron.

On the market on the common internal heat and lead-free long-life soldering iron and 20 w, 25 w, 35 w, 50 w, etc., among them 35 w, 50 w is the most commonly used.

The temperature control

Thermostat soldering iron

Due to the constant temperature inside the soldering iron head, with a magnet type temperature controller, electric control of time and realize the temperature control, namely to electric power, the solder iron temperature rise, when reach the predetermined temperature sensor has reached the Curie point due to the strong magnet and magnetic disappeared, so that the core off contact, then he stopped to electric power; When the temperature is lower than the strong magnet sensor Curie point, a strong magnet and recovery of magnetic, and pull-up permanent magnet of magnetic core switch, control switch on the contact, continue to the electric power supply.

Cycling, and achieved the purpose of controlling temperature. The thermostat soldering iron sort is more, the iron core is generally use PTC element. This type of welding head can not only constant temperature, but can be anti-static, induction, can be directly welded CMOS devices.

High-grade thermostat soldering iron, the additional control device with a digital display of welding head temperature (hereinafter referred to as digital display device, display temperature up to 400 ℃. Welding head with a temperature sensor, the controller can be made of artificial temperature change during welding.

If changing the point for the constant temperature, welding head can be quickly reached a new set temperature. No cable soldering iron is a new type of thermostat welding tools, from no cable soldering iron unit and infrared temperature soldering station unit in two parts, which can realize the 220 v power supply wireless transmission of electric energy is converted to heat energy.

With temperature adjusting knob in iron unit components, continuous adjustable from 160 ~ 400 ℃, and has the high low temperature indicator. Also, design the automatic constant temperature electronic circuit, automatic constant temperature can be set up according to the user in the use of temperature, the error range for 3 ℃.

Solder iron temperature type

Solder iron temperature type attached, there is a power controller can change when using the input power of the power supply, adjustable temperature range is 100 ~ 400 ℃. Solder iron temperature type of maximum power is 60 w, with welding head for copper plating iron welding head (commonly known as longevity head).

Double temperature soldering iron

Double temperature soldering iron to the pistol structure, on the soldering iron handle with a power switch. Switch two points: one is 20 w; The other is a 80 w. As long as the location of the switch can change electric heat.

function

Suction tin soldering iron

Tin tin soldering iron absorption is the piston type suction device and hamonious soldering iron desoldering tools. It is easy to use, flexible and wide application scope, etc. The suction tin soldering iron deficiency is the desoldering every time for only one solder joints.

Tin absorption type electric built-in power supply, suitable for removal of the complete integrated circuits, and speed requirement is not high. The suction mouth, hair heat pipe, sealing ring used in materials, determines the durability of the welding head.
