Today we will have a look into Hot Air Gun which is specially used for soldering the electronic parts. Surface Mount Devices ( SMD) are group of electronic parts which are very small to handle & solder. Most of them are difficult to solder by hand with solder gun but with the help of this Hot Air Gun, it becomes very easy to handle these SMDs.

In the first part of series of articles on Hot Air Gun, we will see what exactly consists the Hot Air Gun and how it is made.

Once you apply power through switch, the controller card will start the blower and its output rate will be as per setting of the knob. The card will also start the heater, which is inside the gun to maintain the temperature of the air blown, as per setting.

The temperature of this particular Hot Air Gun can be set from 150 Degree Centigrade to 500 Degree Centigrade.

The flow of the hot air also can be set through knob.
hot air gun blower mountings
The blower mechanism vibrates when it is on so it is mounted on rubber mountings to absorb the vibrations and to reduce the noise it generates.

Apart from soldering, the Hot Air Gun can be used in many ways. Some of them are listed below-

1. At home – it can be used to paint stripping the oil & solvent based paints from wood.
2. In electronic industry it is used for soldering, desoldering components from the PCB.
3. It can also be used for shaping plastic sheet, pipe & road without leaving any burn marks.
4. The hot air also is used for heat shrinking the plastic tubes around many electrical joints and components.
5. Hot Air gun also can be used to weld plastic tarpaulins and coated textiles.
6. It is also used in footwear industry to correct the fit of customized inline skate boots.

Apart from all of these, the Hot Air Gun can be put to many other uses. Some of them will be covered in next part of the series.

In the mean time if you know any other use of this wonderful tool, do let me know so that we can include it ( of course with your name ) in the list. You can provide your suggestions to info ( at)

Till then Happy Air Gunning !
