The practicality and safety of using manual heating equipment on electric power has been proven many times, but today we will not talk about it itself, but about additional devices and operations performed with their help.
Yes, you understood everything correctly - today we will talk about what attachments exist for and how to use them.
Application of additional equipment
There are several types of instruments depending on the purpose. Let's take a closer look at them.
Hair dryer with attachments
First type - wide nozzle... It is used for heating and removing old paint from wooden surfaces. Removal is done with a spatula or scraper included in the kit. Sometimes the nozzle also has platinum in the form of a scraper, which can be used to remove the old composition during the heating process. The advantage of the tool is that one hand of the worker remains free.
The second type is a ring with a mirror rounded screen... It is used with an upward jet of hot air for heating and bending plastic or copper pipes. Also, the tool is convenient in case of need to warm up and unscrew the heating or water supply pipe, located close enough to the wall, when there is no free access from the back side.
Hairdryer attachments
The third type - round nozzles of various diameters... Used for spot heating of an object.
The fourth type - flattened at the end of the nozzle, resembling the tip of an electric soldering iron... Alternatively, such a nozzle is used on a construction hair dryer for welding polypropylene or polyethylene. That is, the sheets of the first or two films of the second are overlapped, then heated with a "sting" with a simultaneous uniform movement of the hand along the entire length of the joint. Polyethylene can be additionally rolled.
The fifth type - nozzles for a hair dryer for welding with a bar... They are used when sealing, for example, plastic containers, washing machine parts or joining plastic sheets, when you need to get a flat surface. Outwardly, they resemble the previous view, but the sting is somewhat narrower and a tube is welded to it from above, through which the bar is fed.

Small remark... When soldering in this way, it is necessary to use rods made of the same plastic as the surface to be sealed. Otherwise, the connection of dissimilar materials will not last long, or even worse - it will not "grab" at all.
For a better understanding of the performance of this type of work, we demonstrate a video.
Many types of construction work have been around for a long time without the use of forced hot airflow functions. These characteristics are increasingly required in the use of the latest high performance materials in modern building technologies. It is for this reason that the use of a building hair dryer has become so relevant. With only one functionality, a hair dryer can solve dozens of tasks - from standard drying of products to welding linoleum. Carrying out such a variety of works became possible only thanks to the existence of a number of nozzles for the construction hair dryer.
Modern types of nozzles for the building hair dryer
Often, one to several specialized attachments for carrying out various types of work are additionally supplied with the construction hair dryer. They can also be called nozzles, nozzles, or nozzles. Some of them are quite often especially individual (designed for specific work) and are sold only separately from the tool, so when purchasing a hair dryer, you should be prepared for additional purchases. This is especially true for the purchase of certain professional-level models, which are distinguished by a rather high cost. The presence of a larger number of attachments makes it possible to perform much more types and volumes of work with different types of materials. It is the nozzles that are able to form the necessary air flow in a certain way, which significantly expands the standard capabilities.
The existing list of the most common attachments on the construction market includes:
- round focusing attachment(1) - most often designed for sealing gaps of various thicknesses using special plastic welding tapes. The nozzle is used for soldering copper pipes based on the contactless method of processing materials, as well as when repairing skis, veneers, boats, etc.;
- flat nozzle(2) - it is used when it is necessary to remove old putty or remnants of paint materials, film, wallpaper, including for the purpose of deformation of polystyrene plates (under the supervision of a specialist), PVC structures and plastic products. For example, if polystyrene or plexiglass slabs are deformed;
- reflex attachment(3) - heats up plastic pipes before further deformation;
- slotted or slotted nozzles(4) - used for welding PVC products using the slip-on method;
- carved (cutting) nozzles(5) - a similar nozzle was once developed for the implementation of curly or straight cutting of foam;
- glass protection cap(6) - This attachment is designed to work on surfaces that cannot withstand high temperatures (for example, glass and various products from it). A glass protective nozzle for a building hair dryer allows you to remove residues from varnish, paints or putty from surfaces;
- welded mirror(7) - used in the processing of product joints using the contact welding method of various plastic materials;
- wide nozzle- this is one of the varieties of flat nozzles that are used when removing paint from large areas;
- geared nozzle- considered an adapter for carved or slotted nozzles. In addition, the gear nozzle can be safely used for spot welding;
- welded nozzle- the purpose of this nozzle is to directly connect synthetic-type welding cables.
As a rule, the most common among users are wide-jet, reflective, flat, cutting, focusing and slotted nozzles.
Due to the fact that nozzles are made of metals that have a fine structure and which can be very hot and quickly heated during operation, it is important to remember that after finishing work, the hair dryer must be allowed to cool down. A hot nozzle can damage or spoil the material being processed. Therefore, when working with a hairdryer, you should use a special metal stand.
DIY nozzle for a hair dryer
The average price in stores for attachments ranges from 298 rubles. up to 2000 rubles However, if desired, each master can make some types of attachments with his own hands. For this, even pieces of chrome-plated pipe with the required diameter suitable for a building hair dryer can be useful.
To create a nozzle-shaped nozzle, you need to make 4 identical cuts on the pipe and cut out right-angled triangles from all sides, then bend all the resulting parts inward, as in the pictures.
To connect the holes, welding is used, which is subsequently cleaned:
To make a flat nozzle, you just need to hit the pipe several times with a hammer until you get the desired shape.
When choosing a construction hair dryer, it should be borne in mind that all of the listed types of nozzles are rarely included in its kit, since work requires a different volume and power of the blown air. Therefore, it is worthwhile to think in advance about the types and purposes of the upcoming work.
A construction hair dryer or a technical hot air gun is a tool that has come to replace blowtorches in due time. A modern construction hair dryer allows you to release a powerful jet of hot air, which allows you to heat, burn and even solder surfaces. But this tool works from the electrical network, which means that it has more advanced capabilities. The construction hair dryer differs from the simple hair dryer that we use at home to dry our hair in its power and air temperature.
The construction hair dryer can smoothly adjust the temperature, which is very convenient when processing various surfaces of the material. There is also a temperature stabilization system, it is electronically controlled, so the supplied air flow is always the same temperature, and the spiral itself is not very overloaded. All construction hair dryers are equipped with a heat-shielding casing, it allows you to correctly direct the air flow, if you remove it, the risk of burns increases. The handle on the hair dryer is closed, it does not burn your hands during operation.
Types of nozzles for a technical hot air gun
The functionality of the building hair dryer largely depends on the nozzles (nozzles), which are supplied in the kit or sold separately. Round nozzles allow you to solder copper pipes and profiles, they are also used when welding cracks with plastic. Flat nozzles deform plastic, remove old layers of paint, wallpaper and putty. Glass screen protectors also remove paint, but can be used on windows with glass. Reflective nozzles heat plastic pipes for deformation.
Like any tool, a building hair dryer (technical hot air gun) requires careful handling.
Several rules that will allow you to operate the hair dryer for a long time:
- when working, first let the hair dryer warm up the spiral, that is, it is necessary to let the hair dryer run idle for at least 2-3 minutes. The same applies to turning off the hair dryer, after finishing work, reduce the air temperature to a minimum and hold it for 2-3 minutes in this state. This will allow the coil to warm up and cool down evenly;
- follow the instructions of the device. Each job requires its own temperature and air flow rate;
- in no case block the air intake grilles, this will overheat the engine, and it will simply fail;
- the room should be well ventilated when working with a construction hairdryer.
- It is very important to remember that many materials begin to emit harmful substances when heated, and some can catch fire.
A technical, or construction hair dryer is far from the last place in a home craftsman's toolbox. With the help of a hair dryer, you can easily remove old paint, dry surfaces, defrost water in a pipeline, and give plastic parts the desired shape. A hairdryer is irreplaceable when laying roofing material - with a hairdryer you can cut the roofing material, heat it up, or melt it. A hairdryer is used when installing heat-shrinkable insulation, welding linoleum, when soldering with tin or silver.
If you want to, you can make a technical hairdryer with your own hands, but the problem may arise already at the first stage - from which to make a reliable and safe case. With a sufficient selection of hair dryers on sale, it is better to buy a ready-made hair dryer.
Be careful when working with a hot air gun. The hair dryer heats the air from 300 to 600 degrees. Protective gloves will save your hands. When the paint softens with hot air, toxic substances are released. Put on a respirator with a charcoal filter.
Use the technical hair dryer correctly, then it will serve you for a long time.
- Do not overheat the hair dryer during operation, take a break from work every 10-15 minutes.
- The closer you hold the hair dryer to the surface to be treated, the more it overheats.
- Do not turn on the hair dryer immediately to the maximum operating mode.
- Before turning off the hair dryer, switch it to minimum heat to cool it down.
- The hair dryer attachments get very hot, so don't place the hair dryer on surfaces you don't want to ruin.
- Do not change the accessory while it is still hot - you could get severe burns.
- When removing paint from a window frame, unfasten the glazing beads and remove the glass. The glass can easily crack if exposed to a jet of air.
- Be careful when cleaning old paint off the floor. Hot paint particles can fall between the floorboards and cause a fire.
DIY hair dryer repair
All electrical tools tend to break. In case of minor malfunctions, the hairdryer can be repaired by hand. The main working parts of the hair dryer are a heating coil, a fan, an electric motor.
- Try to find the cause of the problem. The power cord may have broken, or the wires may have been burnt, or the coil may have burned out.
- Arm yourself with a screwdriver, a soldering iron, find the hair dryer diagram, which is in the instructions for working with the hair dryer.
- Prepare a surface on which to disassemble the instrument.
- Remember in what order you disassemble the hair dryer. It is very good to use a camera to photograph all the stages of the disassembly. This will help you not to rack your brains over where to attach the extra parts left after assembly.
- Start by checking the plug, cord, contacts. Replacing the cord, buttons or soldering wires is easy with the right skill.
- If the engine or fan breaks down, it is better to take the hairdryer to the workshop.
Technical Hair Dryer Attachments
For the convenience of work, there are special attachments for a technical hair dryer. The attachments are made of steel and can withstand high temperatures.
Also included in the sale kit are devices that will help remove paint from hard-to-reach places.
There are nozzles for welding, brazing and heat-shrinking pipes. A reflective nozzle is suitable for soldering thin pipes.
To warm up and bend the plastic pipe, use reflex nozzles.
A wide flat nozzle works well for removing old paint from surfaces. Protective and shrinking nozzles are used to remove paint from the window - they help direct the air stream to the right place and prevent the glass from overheating.
How to remove old paint
There are many chemicals available to remove old paints and varnishes. The composition is applied to the surface to be treated, after the paint has softened, I remove it with a spatula. The disadvantages of this method include the pungent smell of the chemical composition, the inability to qualitatively remove paint from large areas. Old paint is difficult to attack even with the much-advertised paint remover chemicals.
You can mechanically clean the surface with a grinder or grinder with special attachments.
Removing old paint with a hot air gun is more practical and convenient than other surface cleaning methods.
For work you will need
- technical hair dryer
- extension
- nozzles for hair dryer
- spatula and special tools for scraping paint
- brush
- protective equipment - gloves, respirator
Do not hold the hair dryer too close to the surface. Heat small areas from a distance of 5-10 cm. When the paint starts to bubble, remove it with a spatula. The spatula spatula, in contrast to the spatula, is more rigid, it is more convenient for it to remove peeling paint. You can take a narrow spatula.
Do not heat a large surface at once. Take an extension cord for ease of use. It is easier to remove paint from wood surfaces than from metal or plastered and painted surfaces. Ventilate the room often.
Hold the hair dryer by the handle, do not cover the air intake holes with your hand - it can quickly overheat. When removing paint from a window, it is better to remove the frame - it is more convenient to work this way, and it is easier to get to hard-to-reach places on the window block.
Hold the hairdryer in your right hand, directing the air flow to the desired location. When the paint starts to swell and bubble, immediately remove the softened paint with your left hand using a spatula.
Remove small pieces of paint with a brush.
The instruction does not always reveal all the nuances of how to use a construction hairdryer. This multifunctional tool will come in handy in a wide variety of areas of life and will prove to be very useful in production. Its main function is to warm up and direct air masses. As auxiliary elements, replaceable nozzles are used, designed to accurately supply a jet of air and protect the surrounding objects. However, the use of the building hair dryer does not end there.
The list of operations performed with a construction hairdryer includes hundreds of different types of work. Describing the purpose as a whole, the tool is useful where precise and directional exposure to high temperatures:
- drying, heating, removing paint and varnish coatings, wallpaper;
- bonding, deformation, welding of materials;
- defrosting communications, metal products, locks, rusted bolts;
- heating or drying adhesives;
- tinting, stickers, films;
- installation of heat shrinkable parts and other installation work.
The construction hair dryer is widely used for car repairs, creating decorative elements from plastic or foam, when laying water supply systems made of polypropylene. It is an indispensable tool during major or minor repairs, why it is most often purchased. The complete list of possible applications of the building hair dryer can be expanded and replenished with clarifications, but the general idea will not change.
Only limited tool performance can reduce the range of use somewhat.
Governing bodies
It is quite simple to use a technical hairdryer; not only an experienced master, but also a beginner will cope with this task. The design of the tool is very simple and straightforward, all controls are located on the handle or on the side of the body.
In household models, the power key serves as a temperature regulator and has several positions. Sometimes this adjustment is supplemented by a smooth one, brought out by a separate slider. Professional hair dryers are equipped with a block electronic control, in them the temperature is set with special keys or a roller.
The air flow rate is not adjustable, it is temperature dependent and automatically set. This decision is quite logical, because the heated coil needs to be cooled, otherwise, the instrument will simply burn out.
In general, this is all about tool management. In addition to being a safe device, the hot air gun is often equipped with protective options designed to preserve equipment and keep the operator safe.
First use
After the first connection of the hot air gun to the network, foreign smell Is normal for a new device. The heating element and the coil warm up, dust and grease residues burns on them, a specific aroma passes quickly.
Only the smell of melted plastic should be suspicious.
As the manufacturers indicate in the passport, before starting work, or at its completion, the tool must work at a minimum temperature or in cooling mode for several minutes. This will eliminate sudden temperature changes and extend the life of the hot air gun.
Despite the safety of a technical hair dryer, do not neglect the general safety rules:
- the user must wear protective goggles and gloves;
- all operations are carried out in well-ventilated rooms, some materials, when heated, can emit harmful chemical fumes;
- it is necessary to use a variety of loops, hangers or hooks to protect the tool from breakage.
The main list of what can be done with an ordinary industrial hairdryer will interest those who are planning to make repairs in a house or apartment. It is also recommended to watch several video reviews on the operation of the hot air gun.
How to remove paintwork
Removing paint or varnish is a very common operation for a hot air gun. If earlier this procedure took a lot of time, then with the help of a hair dryer, the problem becomes a minor task. Using a variety of attachments, the user removes the top coat from any material whose temperature or melting time is higher than the paintwork.
This method of removing top layers of paint requires a hair dryer that works at a temperature of 550 - 600° C... The nozzle of the hair dryer is directed to the area to be treated and held until bubbles appear. After the paint is peeled off and removed with a spatula. The easiest operation is carried out on wood products (windows, fence, window sill), but it is more difficult to remove paint from metal. The high thermal conductivity of the metal structure dissipates heat, reducing working efficiency.
It is even more difficult to remove paintwork materials from plastic, such work will require considerable skill, good theoretical knowledge of the minimum and maximum melting temperatures.
Another popular area of application of the tool in everyday life is the connection of plastic pipes with a technical hairdryer. With the help of a hot air gun and a reflector nozzle, you can lay the water supply. High air temperatures will not only melt and glue the couplings, but also help shape a pipe.
To achieve a strong connection, you need to correctly determine the moment of welding. Two parts of the pipe are brought to the nozzle, heated to a soft state at a temperature of 200-300 ° C. After they are connected together, holding for 30-40 seconds.
Welding seams
Bonding seams of linoleum or PVC with a hairdryer is performed in several steps. First, the materials to be welded are adjusted, after which at the point of gluing at an angle, their edges are trimmed with any knife.
The future seam is superimposed filler strand, then it is blown in the right place with a hot air gun at a temperature of about 300 ° C. When the composition becomes liquid, it is spread over the seam with an ordinary rubber spatula and allowed to dry.
Bonding films
Another example of what a building hair dryer is for is working with films. The material used is easily affected by temperatures, therefore all actions should be as clear and fast as possible. The film is welded with an overlap, one edge is superimposed on the other by about 3 cm along the entire length of the seam. When working with such materials, it is enough to set minimum temperature, process the place of gluing, then roll this place with a roller.
If the temperature is found to be insufficient, the operation is repeated with a slight increase in productivity until the seam is firm.
The construction hair dryer is very popular with experienced craftsmen. The tool is widely used in construction site, design or renovation. With its help, you can make various crafts or decorative elements, weld, melt, dry or deform materials, building compounds.
