The heat gun is mainly a tool that uses the hot air blown by the gun core of the heating resistance wire to weld and remove components. According to the working principle of the heat gun, the main part of the heat gun control circuit should include temperature signal amplification circuit, comparison circuit, SCR control circuit, sensor, wind control circuit, etc. In addition, in order to improve the overall performance of the circuit, some auxiliary circuits should be set, such as temperature display circuit, shutdown delay circuit and zero crossing detection circuit. The temperature display circuit is set to facilitate temperature adjustment. The temperature displayed by the temperature display circuit is the actual temperature of the circuit, and the worker can manually adjust it according to the temperature displayed on the display screen during operation.

The main purpose of adding shutdown delay circuit is to improve the safety of the circuit. This circuit allows the circuit to stop working after the gun core is blown cold, so as to avoid injury to people or objects caused by excessive temperature of the gun core when the power supply is just turned off. There are some heat guns in the market that are not very demanding. Although they can work normally without zero circuit, they are not technically perfect. The purpose of adding zero crossing circuit in this design is to make the thyristor in the circuit conduct at the AC zero crossing point, so as to avoid the thyristor conducting at the positive half cycle or negative half cycle high level to produce too high shock pulse wave, which will pollute the power supply and affect other electrical equipment in parallel in the circuit.

• Common Heat Gun Type

This kind of heat gun is mainly characterized by unstable temperature, high and low temperature, and unstable air volume. The scale of this kind of heat gun only adjusts its power, so the temperature rises very slowly when starting up, for several minutes, and then the temperature rises linearly. If you are not careful, you will burn things. Such as power amplifier, CPU, circuit board, etc. Although it has temperature detection, it seems that it is only used for over temperature protection, and does not really adjust the temperature value.

• Standard Heat Gun Type

The scale of this kind of heat gun is really used to adjust the temperature. When starting up, the temperature rises quickly and can be reached in tens of seconds. Moreover, the temperature will not rise in a straight line. It can be adjusted within a small range, and the air volume is relatively stable. It is suitable for repairing mobile phones.

• Digital Temperature Display Heat Gun Type

This heat gun performance is basically the same as the second one, that is, there are multiple digital temperature displays, some of which are very accurate. However, some display temperature inaccuracy, which is easy to produce false sense. In addition, according to the difference between the manufacturer and the production time, it may not be practical long ago.

It should be added that the actual operating temperature measured by the digital thermometer is 350-400 degrees at the air outlet, about 300-350 degrees at one centimeter and 260-300 degrees at two centimetres. It can be tested with a digital multimeter with a thermometer.

At the same time, some machines are equipped with power or other voltage and current indicating dials. Some parts can be replaced.

If a heat gun without digital temperature is used, it can be estimated by blowing a piece of paper at 3cm with the heat gun. If the paper will not turn black soon, it is appropriate to turn yellow slowly.

• High Temperature Heat Gun Type

The high-temperature heat gun, whose temperature can reach 800 ℃ or even 900 ℃, can be used only when it is fixed on the equipment and connected with compressed air or high-pressure air source.

The high-temperature heat gun is generally equipped with one or two temperature sensors for temperature control, and also equipped with an anti dry burning device to prevent the heating wire from overheating and burning out due to lack of air.

• Roof Works

When building or repairing the roof, it is necessary to weld a large number of plastic films, waterproof coiled materials, and detail welding of some special parts, such as inclined roof, fence wall edge, dome skylight, etc., all need to use heat gun. As the roof is affected by the temperature difference between cold and hot, precipitation, etc., the welding quality will directly affect the service life of the roof.

• Roof plastic film welding
• Dome roof details welding
• Welding of plastic sealing waterproof coiled material and modified asphalt for inclined roof
