  • thermocouple connector;
  • stop button;
  • desktop fan key;
  • backlight switch;
  • top cooling button;
  • thermal controller for bottom heaters;
  • programmable controller of the upper IR heater.

The temperature of the upper IR heater can reach from 220 to 270 degrees. The lower platform warms up to 150-1700 C.

Design and principle of operation

Soldering equipment consists of the following elements:

  • Control module. This unit is equipped with a temperature control chip and a step-down transformer. It is thanks to this module that the user can independently select the heating temperature.
  • Soldering iron. The main element of the tool, which is connected to the control module.
  • Stand. Needed to secure a heated soldering iron when it is not in use.

Some models are additionally equipped with thermal tweezers, a hair dryer and a compressor.

Rules of use and safety precautions

The following list contains standard recommendations from manufacturers:

  • Before starting operation, check the serviceability of the device, connecting cables, and integrity of the housings.
  • When performing work operations, do not use actions that could damage the station.
  • Flammable and explosive objects are removed from the work area and immediate environment.
  • Do not touch nozzles or other heated parts.
  • Provide ventilation of the room to prevent harm to health from chemical reagents.
  • When storing and during breaks in work, use a specialized stand with automatic shut-off.
  • For long-term storage, disconnect the equipment from the power supply.
  • Do not use a soldering iron in rooms with excessive humidity or with wet hands.
  • Prevent children from accessing potentially dangerous equipment.

For your information. The service life of the soldering iron can be extended if you use the minimum heating temperature and maximum fan (compressor) speed.

During operation, you should follow the correct sequence of actions when changing nozzles. Such procedures are performed only after the temperature has dropped to a safe level. If malfunctions are detected, the equipment is immediately disconnected from the 220 V network. Self-repairs should not be done without appropriate qualifications. If necessary, contact experienced specialists to diagnose and replace failed parts.

Soldering station and its main types

Before choosing soldering irons for further use, you need to familiarize yourself with the main types of such tools.

Contact soldering stations


Contact models - ideal for beginners
Quite often, contact models are used to repair electronics. Most of them use lead-tin solder. However, some soldering irons can work without lead. There are two main types of contact devices:

  • Analog. It is equipped with a special electromagnetic relay and a temperature sensor, which are responsible for automatically turning the soldering iron on and off.
  • Digital. They have a built-in programmed microcontroller with which the heating temperature is regulated.

Additional Information! Such models are ideal for beginners who have not soldered before.

Contactless soldering stations

In such devices, soldering is carried out using thermal radiation or heated air. Contactless models can be divided into two categories:

  • Thermal air. Equipped with a turbine hair dryer that supplies hot air to the surface.
  • Infrared. They have an infrared emitter installed, with the help of which soldering work is carried out.

In rare cases, there are combined devices equipped with both a hair dryer and an emitter.

Work in practice

Before starting work, it is important to properly configure the IR soldering station.

Settings

After fixing the printed circuit board on the heating table and connecting the IR emitter to the microprocessor, they proceed to setting up the operation of the station. This is done using the interface keys of the thermal controllers of the upper and lower heaters.

The display of the bottom heating controller at the top shows the current temperature. Use the buttons on the bottom line to set the final value of the degree of heating of the printed circuit board.

The programmable top heating controller has 10 options (thermal profiles). The thermoprofile reflects the dependence of temperature on time. That is, warming up can be programmed in steps. Each step sets a certain time during which the temperature does not change.

Difficulty in work

Mass-produced infrared soldering stations are easy to use and easy to operate. Difficulties in the operation of the station may arise due to a discrepancy between the actual characteristics of the station and the data in the accompanying documentation. The equipment manufacturer is responsible for this in accordance with the warranty.

For people who repair modern electronic devices at home, a homemade infrared soldering station is a must. Purchasing professional equipment makes sense for workshops where there are large volumes of repair work.

Criterias of choice

To purchase a high-quality soldering iron, you need to familiarize yourself with the basic selection criteria.

A heating element


The heating element is one of the main components of a soldering station.
Ceramic and nichrome heaters are most often used in such devices. The latter are most often installed in budget models. People who regularly repair electronics should not buy models with nichrome heating elements. The fact is that they are not suitable for long-term and constant use.

Important! For production purposes, it is better to purchase a model with ceramics. However, this element also has disadvantages. For example, it does not tolerate uneven heating well and sometimes cracks due to it.

Equipment


Hairdryer - must be included
When choosing a soldering iron, you need to make sure that all the necessary complete parts are sold with it. These include:

  • tweezers;
  • heating hair dryer;
  • thermal emitter for heating boards;
  • additional fittings.

If the package is incomplete, it is better to refuse to purchase such a device and look for another model.

Power

One of the most important criteria that you must pay attention to when choosing. To determine the appropriate power for a compressor soldering iron with a hair dryer, you need to know in advance for what purpose it will be used. For example, if you need it to repair laptops or cell phones, it is better to choose models with a power of no more than 60 watts.

Maintainability

Another criterion that should not be forgotten is the maintainability of the device. The fact is that soldering irons can break the heating element or tip. Therefore, sometimes people have to repair them. However, in order to avoid having to repair anything, you must first buy a high-quality soldering iron that will work properly without breakdowns.

Important! It is recommended to read customer reviews in advance to determine the quality of a particular soldering iron model.
