Hot glue gun: advantages, application features. What glue gun glues: use cases What can you use a glue gun for?

Today glue guns are widely used in everyday life and at work. They are used by needlewomen and builders, home craftsmen and professionals. A huge range of products significantly expands the use of a glue gun, allowing you to make a choice based on the functional needs and technical characteristics of the device.

The devices are available in different sizes, capacities and operating temperatures. With their help, even those materials that are difficult to contact with modern adhesives are instantly glued together. And for small parts that require precise positioning, there is simply no better retainer. Although there are drawbacks to this versatile tool.

How a glue gun works

Outwardly, the device resembles a small drill. Its grip fits comfortably in the hand and the trigger lever is comfortable to operate. On the back of the gun there is a hole in the receiving chamber where the glue stick is inserted. After turning on the device, under the action of heating the inner sleeve, the “cartridge” gradually softens to a viscous state within 3-5 minutes, depending on the model and performance of the pistol. Liquid glue is squeezed onto the surface to be glued using a lever through a nozzle located in the front of the device.

Depending on the design, the thermo gun is powered by:

standard outlet;
built-in battery;
generator.

After turning on the device and installing the glue stick in the receiving hole, several minutes should pass before the gluing process starts, so you should not press the lever to speed up melting. In the future, the movement is corrected by the force applied to the "trigger". The amount of molten mass coming out of the gun also depends on the diameter of the nozzle.

The squeezed out glue sets almost instantly, and therefore, the accuracy of its application is an important point when gluing various elements or parts, especially small ones.

It is important to pay attention to the fact that after disconnecting the glue gun from the power supply, the molten mass may continue to spontaneously flow out of the nozzle. In this regard, the device should be turned off shortly before the end of work, or paper should be placed under the nozzle of an uncooled pistol to avoid the appearance of stains and dirt. But a similar defect is inherent in cheap models of thermal guns. Nozzles of high-quality devices are equipped with shut-off valves, which are either a nipple or a plate with a spring.

Do not pull out or twist unused rods, as these actions lead to cracking of the internal parts of the apparatus. Also, it is not allowed to try to insert glue "sticks" that do not match the diameter of the inlet on the device body.

Typical design

The glue gun is simple enough. In its case, made of impact-resistant plastic with dielectric properties, there are only a few nodes:

thermal chamber with thermoelements connected to it - from all sides or only from below. The performance of the gun and the permissible thickness of the materials to be glued directly depend on its dimensions and heating power;
a feed mechanism consisting of a rod pusher equipped with transmission levers. This unit is controlled by a "trigger";
guide receiver made of heat-resistant plastic or tubular rubber. He is responsible for the correct advancement of the glue sticks, and is located in the gap between the heat chamber and the inlet;
nozzle, or nozzle - designed to form a jet of liquid glue and the possibility of accurately applying the composition to the gluing site.

The body of the device in most cases has slotted windows through which visual control of the guiding receiver is carried out. For the convenience of operation, the gun is equipped with a folding bracket, which is necessary when installing the device in a vertical position.

When the glue gun is on, it is not recommended to lay it on its side, as its internal components will be filled with melted glue, which will lead to a quick failure of the device.

Thermal guns are available in different capacities:

amateur - from 50 to 150 W;
semi-professional - from 150 to 250 W;
professional - more than 250W.

The devices have different guide chamber volumes, capacities, melt temperatures, feed rates and glue stick diameters used. Pistols can be equipped with a set of nozzles, have two heating modes, and their cost is low and available to everyone.

Advantages and disadvantages of a thermal gun

Using a glue gun gives ample opportunities when gluing various materials. With its help, joints are sealed and narrow seams are poured, canvases or sheets of heat and sound insulation are fixed, ceiling moldings and loose wallpaper are glued, stucco moldings and decorative elements are attached to walls or ceilings. Such devices are indispensable in cases of minor repairs, when it is necessary to fix, for example, a mosaic tile that has flown off or a pebble that has fallen out of a decoration.

Glue guns are used by radio amateurs and electricians, seamstresses and car mechanics. Among the main advantages of the devices are:

instant bonding;
high fastening strength;
neat appearance of the connection of even small parts;
environmental friendliness of the used glue sticks;
moisture resistance of contact joints;
the possibility of using on surfaces that do not allow mechanical stress;
ease of use.

The disadvantages of glue guns include the fact that machines should not be used to glue materials, one of which will heat up during operation. The glue, in this case, will melt, and the fastened parts will disintegrate. Weak bonding also occurs when materials are glued to concrete, some types of plastics and plastered surfaces.

If you sometimes have to glue fabric, natural or artificial leather, or glue rhinestones and all sorts of jewelry, then a glue gun should definitely be in your toolbox. Simple models of such an adhesive thermal gun are inexpensive (starting from 300 rubles). It is only important to choose the right pistol model so that it is convenient to use it, since it can be used not only for needlework, but also for other repair and construction work.

The glue gun is also called "hot glue", which very accurately reflects its principle of operation. The glue stick is inserted into the "barrel", where it is melted and fed in liquid and at the same time hot to the desired area.

About how to safely use a glue gun, how to choose one and what can be glued with it besides jewelry for needlework.

This diagram shows the device of a thermal gun of any model. The glue stick is installed in a special hole. Then this electrical appliance is connected with a cord to a 220 volt network. However, there are models that work not from the mains, but from the battery. Accordingly, they will cost significantly more than conventional models.

After a few minutes (5-10), the built-in heating element will melt the solid glue stick. Hot glue will be dispensed from the gun nozzle when the trigger is pulled.

To make it safer and more convenient to work with hot glue, the temperature of which can burn the skin, there is a special leg (stand) on the pistol body.

Glue guns differ not only in appearance, body size and different parameters of its operation, but also in the diameter of the glue stick (7 or 11 mm). Some models work with 7mm rods, others use 11mm rods.

For small decorative sewing work, needlework, it is better to use guns designed for glue sticks with a diameter of 7mm. Firstly, the size of the body of such a gun will be smaller and more compact, and secondly, the glue will heat up faster. Accordingly, his price will be significantly lower than a pistol designed for professional installation and construction work.

Handicraft glue sticks are produced not only colorless, but also painted. This allows you to glue rhinestones, jewelry without traces of the glued area. There are also special rods with different kinds of fillers, such as glitters. Consider all this when buying a pistol and rods for it.

The thermal gun is used for different purposes, hence the prices for them from hundreds of rubles to several thousand. But for needlework there is no need for a powerful heating element, high speed and high performance. It is enough to buy an inexpensive pistol within 300-500 rubles and it will work efficiently and reliably. And if necessary, it can be used for other purposes, for example, for repairing shoes, broken ceramics, etc.

If you choose an inexpensive model of a thermal gun, then remember that you can use it for a limited time (15-20 minutes), followed by a break for cooling. This is due to the fact that the heating element for such models does not turn off automatically and the adhesive can simply overheat, which will lead to a number of negative consequences. For example, glue will begin to flow out of the body joints, "pour" not only the surface of the desktop, but also the inner parts of the electric heater.

The glue heating temperature is another parameter by which you need to choose a glue gun. The low temperature range starts from 105 degrees of heating the glue rod, and professional models can heat the glue up to 200 degrees. Accordingly, they will have a heating element of different power, from 20 to 100 watts or more. For needlework, it is better to buy a low-power pistol. True, it heats up the glue more slowly and cools down faster, but the hot glue will not damage the fabric or other material.
For those who need a universal glue gun, we can recommend buying a model with switching heating mode (105 and 165 degrees).

The nozzle of the pistol can have not only a conical shape, but another. For needlework, an elongated and long nose is best suited. Firstly, you can adjust the glue flow, which makes it easier to glue small crystals, sequins, etc. And secondly, it will be easier to reach hard-to-reach places with a long nose.

Pay attention to the quality of the body material, as well as the tightness of the connection of its parts. In case you forget to turn off the thermo gun, reliable connections of its parts and durable material of the body will protect your hands from the hot glue melted and flowed out of the cracks in the body. Leading brands of glue gun manufacturers - Bosch, Dremel, Makita, Hammer, etc.

As mentioned above, first install the glue stick. Then plug this electrical device into a power outlet. Wait 5-10 minutes. The heating time of the glue depends on the diameter of the rod and the power of the heating element, which can be read in detail in the instructions attached to it.

Before starting to glue, check to see if hot glue will come out as a drop. If no glue drips, then the rod is not yet fully heated. On some models, the glue is delivered in a viscous stream. After that, apply glue in the required places and install the jewelry, rhinestones, etc. prepared by you.

Prepare everything you need for work in advance. Make a marking of the places where the glue should be applied, prepare the accessories and materials you need, jewelry. Inexpensive model gun has a limited run time and will need to be turned off to cool down. For inexpensive models, the operating time is 15-20 minutes, and even better if you manage to do the intended work in 10 minutes. Please note that the weaker the power of the heating element of the gun, the faster you need to work, since the glue will heat up to a temperature of only 105 degrees, and therefore will harden faster.

After work, place the gun on a special plate, approximately, as shown in this photo. This will prevent hot glue residue from leaking out on your table.

5. What can be glued with "hot glue"

The glue gun is used not only for needlework, gluing rhinestones when sewing clothes and various jewelry. It is also used for gluing wood, ceramics, chipboard, plastics and other materials.

Melted glue can be used to seal cracks in window frames, joints to honey with tiles, perform various plumbing works (sealing joints). It is very convenient to use such a gun when restoring book bindings. You can even do simple shoe repairs, etc.

Like any other electrical appliance, the glue gun requires adherence to certain safety measures. You can see in this photo to what extent you can burn yourself with hot glue if you allow the gun to overheat and hot glue flowing out of the cracks in its body.

Do not forget also that the wire connecting the gun to the outlet must be serviceable, away from the hands of the working person. If possible, choose a wire in a thick protective sheath and preferably not too short.

One of the most used tools in everyday life is increasingly becoming a glue gun. Hot glue guns are used for handicrafts and repairs. To prevent such a tool from lying around at home without using it, it is important to seriously approach the choice of a suitable model, and also find out what it is applicable for.

What is the glue gun used for and how does it work?

The glue gun is a compact electrical appliance, similar in appearance to a gun. The glue for it is used in the form of rods of various sizes, markings and colors. The principle of operation is that the tool heats the stick of glue inside it, melts it and feeds it in dosage through the narrow tip.

Before you buy a hot glue gun, you should read the useful information about them, which can be found below.

Thermal guns are used in everyday life for repairs and handicrafts.

What the thermo gun glues:

wood,
plastic,
metal (before that it is advisable to warm up),
glass,
the cloth,
ceramics,
carpets,
rubber,
cardboard,
paper,
some types of plastics and others.

Thermal guns are not used for:

polyethylene,
foam,
thin synthetic fabrics,
concrete,
plaster.

Thermal guns can also glue together different textures and details. Thermal guns are widely used in design work when carrying out repairs, for decorating, making crafts, collages, panels, when creating compositions from flowers, cones, branches, buttons and much more.

The advantages of a glue gun are as follows:

The elements are glued together instantly (1-3 minutes).
Great for most materials.
The connection has high strength (parts can be separated only by heating).
Leaves almost no residue when removed.
It fills voids well, impregnates, seals seams.
Cures completely to full depth (useful for sealing).
The glue is non-toxic even when melted.
The seam at the gluing site is well resistant to moisture.
Glue sticks have a long shelf life.
Cost-effective gluing (glue is delivered very thinly from the gun, and spare glue sticks are relatively inexpensive).
The pistol is quite safe and ergonomic (even suitable for children's creativity).

Glue gun types and glue selection

How to choose a glue gun? There are various classification of hot glue guns. The main subdivides them into professional and household... The second volumetric criterion divides pistols into automatic and mechanical.

Everything automatic thermo guns belong to professional(used more on conveyors).

Household the same pistols have mechanical glue feed(by pulling the trigger) and are themselves divided into types depending on the selection of criteria.

The diameter of the holders of the glue rod for thermal fillers. Most often, pistols with a cartridge diameter of 7 and 11 mm are encountered (they can be 7–8 and 11–12). The seven-millimeter one is suitable for infrequent household use (1-2 times a month). If the gun is used constantly (for example, during repairs), it is recommended to choose a cartridge diameter of 11 mm. A larger diameter will provide greater speed and allow you to handle larger volumes of work.
Temperature of heating glue in thermo guns... In modern models of pistols, temperature fluctuations are from 105 to 200 degrees (there are up to 500). For the usual rare use of a glue gun and using a classic glue stick, a heating temperature of 105 degrees is sufficient. Increasing the temperature increases the speed of the hot melt gun.
The speed of the hot glue gun. The range of speeds for glue guns ranges from 5 to 30 g of supplied glue per minute. High speed is important when gluing large parts, since hot melt glue dries and hardens very quickly and it will be almost impossible to cover a large surface area with it at low speed. For decorative and minor repair works, a speed of 5–15 grams per minute is sufficient.
Power... The power of the thermal gun is directly proportional to the two previous characteristics. To increase it, you can also add a parameter for the heating rate of the thermal gun itself. It varies around 4-5 minutes. The faster the gun heats up, the higher the heating temperature and feed rate, the greater the power of the glue gun itself. And vice versa.
Glue gun trigger. The hammers are rotary and sliders. Professionals appreciate the swivel version more for its convenient operation and easy, precise dosing. There are also non-Kurdish pistols, in which a hot melt glue rod is pushed through with your fingers.
Frame adhesive heat gun. The gun body must contain a very tight check valve. If it is absent or of poor quality, in the case of vertical operation with the nozzle upwards, the glue may leak and fill the contacts and the trigger, after which the gun will be unusable.
Glue gun cord. Thermo guns are available with cords, with detachable cords and rechargeable ones. The cord can sometimes interfere with work and restrict movement, the battery makes the pistol itself heavy, the gun with a detachable cord works after disconnecting it from the mains for 10–20 minutes.
Nozzles-nozzles adhesive heat gun. There are models with only one nozzle, models with different nozzles and models with nozzle changeover. It is recommended that when choosing a nozzle, pay attention to the item "protection against drops". These nozzles contain a ball inside and prevent glue from dripping when ready.

When choosing a heat gun, you can also take into account some additional criteria:

Varieties of hot melt glue

Part of the classification of hot gun glue depends on the gun itself. It is recommended to choose hot melt glue according to the following parameters:

Diameter and length. The most popular rod diameters are 7 and 11 mm, corresponding to the popular pistol cartridge diameters. The length varies from 4 to 20 cm and also depends on the length of the cartridge into which you need to insert the glue stick.
Melting temperature. The melting temperature range of the glue usually ranges from 100 to 150 degrees. When choosing, it is important to take into account the temperature regime of the gun, for which the hot melt glue is selected and the place of its application. When bonding areas with little heat, it is recommended to choose high temperature rods. And vice versa.
Colour... The white transparent rod is universal. Opaque colored rods (other than black) can also be classified as universal. Their choice depends on the color of the surface that needs to be glued so that the joint is the least noticeable. White opaque rods are usually marked and are used for working with glass and metal. Yellow transparent hot melt glue is used for working with wood, paper and cardboard. Black and gray rods work as sealants and insulation. The range of colors is very wide. The purpose and physical properties of each adhesive can be checked on its packaging.

Using a glue gun: instructions

Preparation of the workplace. It is important to protect the surfaces from dripping glue.
Installing the gun. To do this, fold back the support leg.
Switching on the device. Connecting the battery or plugging in the power cord. If there is a button on the case, turn it on with it.
Kernel. Insert the glue stick all the way into the hole in the back of the gun.
Heat. The heating timeout depends on the gun type and is usually 4–5 minutes. When the gun is ready for use, a drop of glue appears on the nozzle.
Preparation of the bonded surface. Remove dirt and dust from the surface, dry, if necessary, sand.
Glue feed. To supply glue, you need to press the trigger of the thermo gun. The amount of glue depends on the number and depth of trigger pulls.
Connection of surfaces. After applying the glue, the surfaces are bonded. It is important to immediately precisely dock the seam, otherwise it will be impossible to move it later. You need to hold the joint for a few seconds for the glue to set.
Replacing the rod. If you run out of glue sticks, it is recommended to insert a new one into the hole and, using a little pressure, push the previous one. When changing colored rods, if a different color is required to continue work, the rod must be removed by rotating it around its axis (the gun must be heated). After inserting a new rod, you need to pull the trigger several times to remove the remnants of the previous color.
At the end of the work with a thermal gun, it is turned off from the network, and the nozzle is wiped with a piece of cardboard. Glue threads left over from work can be easily removed by hand or with a vacuum cleaner with a small brush.

Safety when using a hot glue gun

The safety rules with a glue gun are quite simple and are as follows:

It is important to keep small children and pets away from the workplace, as high temperatures (up to 200 degrees) can cause injury.
When working, the gun must be installed with the nozzle down on the stand.
Compliance with safety measures when working with hot glue to prevent burns.
The switched on thermo gun should not be left unattended.
Dropping the appliance may result in fire.
If you use the glue gun continuously for a long time, leave it alone for 5 minutes every hour.

How to use a hot glue gun, video:

The service life of a hot glue gun directly depends on the correctness of its operation. Let's talk about the last factor in more detail.

Advantages of the glue gun

Due to the fact that it takes from 1 to 2 minutes to solidify the heated polymer, the hot melt glue gun allows you to quickly glue a variety of materials: wood, metal, all types of plastics, rubber, ceramics, fabrics and paper.

It is not suitable for working with plaster and concrete, there may be problems when gluing polyethylene.

The strength of the adhesive joint obtained with this tool is practically not inferior to mechanical fastening, and it can be dismantled only after the glued parts are heated.

The hot melt gun also captivates with its cost-effectiveness: waste of the adhesive composition is minimized due to the use of a dispensing device, and the cost of glue sticks is several times lower than the cost of the same volume of traditional liquid glue.

Preparing the tool for work

Select a glue stick of the desired diameter (7 or 11 mm) and insert it into the special hole in the back of the gun body until it stops.

Do not be confused by the fact that some of the rod will remain sticking out of the pistol, this is quite normal and does not affect the workflow in any way.

Place the instrument on a stand (folding or stationary), check the stability of its position and, by plugging the power cable into, turn on the power button.

In order for the heat chamber to warm up to operating temperature, it will take from 4 to 8 minutes, depending on the power of the heating element.

The readiness of the glue gun for work will be indicated by a special indicator on the body of the tool. If there is no such indicator on your gun, the readiness of the heat chamber can be checked by easily pressing the trigger of the feeder.

A drop of glue emerging from the nozzle will unmistakably indicate that the tool can be used.

Working with a hot glue gun

The amount of glue coming out of the tool is regulated by the depth and the number of times the feed mechanism trigger is pressed.

Press the trigger, squeezing out the required amount of glue from the nozzle of the gun, apply the glue to the glued surfaces.

The penetrating power of the heated glue is maintained for about ten seconds after exiting the nozzle. It is during this time that you need to have time to press the parts to be glued to each other and fix them within a minute.

In the case of applying a large volume of glue, its hardening time increases several times, and the required fixing time of the parts to be glued increases accordingly. Sometimes it can take 5-10 minutes.

During even short breaks in work, place the tool on the stand with the nozzle down. This is necessary so that the melted glue mass does not flow into the feed mechanism and does not disable it.

In the process of work, the glue stick ends sooner or later. The signal about the need to insert a new rod into the gun will be the cessation of the supply of adhesive from the nozzle simultaneously with the weakening of the resistance of the trigger when it is pressed.

Sometimes it becomes necessary to replace an unused glue stick with another. In this case, grasping the old rod with two fingers, it is carefully turned back and forth around its axis, and then removed from the heat chamber.

After inserting a new rod into the gun, pressing the trigger removes the remnants of the old adhesive and only after that they continue to work.

Attention! To avoid damage to the heat chamber and the feed mechanism, all work on removing and replacing the rods must be carried out with the gun turned on and warmed up to the operating temperature.

Keep track of the time you use the tool. It is not recommended to keep amateur hot glue guns switched on for more than 20 minutes. For a professional instrument, this time range is 1 to 2 hours.

In the process of working with a glue gun, thin glue threads resembling a cobweb are often pulled behind the nozzle. Don't be nervous, let them cool and then remove them by taking them off or wrapping them around your hand.

Never leave a hot glue gun switched on unattended!

Good luck to you! May you succeed!

The hot glue gun is a tool that has become popular due to its simple design, while its adhesion strength is top notch and does not take long. This device is called folk without reservations, since it is found in almost every home.

What is a glue gun and where is it used?

The main advantage of this device is its simplicity and ease of use, and consumables cost a penny. And the device itself is not expensive, but it opens up a lot of possibilities. The thermal gun is in the arsenal of builders, it helps to fix engineering communications, seals, glues, fills the seams. It is used by needlewomen, florists, designers, making it possible to glue various accessories, make all kinds of designs.

Radio amateurs actively use glue guns when repairing microcircuits and wiring. Even artists have seen decorative value in the polyurethane melt by creating drawings from the glue mass. In household use, this thing is irreplaceable; with the help of such a pistol, even broken dishes can be restored.

The glue gun connects various parts almost immediately, since the polymer, heated to a certain temperature, solidifies in just a few minutes; the gluing is durable and does not make you wait for setting, unlike other types of glue. The hot gun is used for working with wood, plastic, leather, glass, metal, paper, ceramics, fabric, PVC, rubber, foam.

It is not recommended to use it with concrete or plaster, although this is a controversial issue, tests show that a hook made of metal glued to the wall can support a relatively large weight. It is rarely used in working with polyethylene, since at high temperatures it melts and deforms. Polymer glue is not used in places with a temperature equal to the melting point of the glue itself. And most importantly, if it is necessary to remove glue from almost all surfaces, this can be easily done.

The cured polymer is elastic and moisture resistant. Polymer glue is harmless.

It is necessary to work with such a tool carefully, adhering to safety rules, since burns are possible, the melting temperature of the glue reaches 200 degrees.

Hot glue gun working principle

A thermal pistol is a hand-held tool, very similar to the type of weapon. It also needs to be charged, only not with live ammunition, but with cylindrical rods made of polyurethane glue of various diameters. The gun itself is made of heat-resistant plastic, which makes it lightweight. Powered by a 200 W socket, some models are equipped with a built-in rechargeable battery. On the back of the device there is a hole into which a glue stick is inserted, the diameter of the tube depends on the model.

Spare glue enters the bushing of the push mechanism, falling into a special pipe- rubber receptacle, and from it the edge of the rod abuts against the heating chamber, in which the polyurethane melts, turning into an adhesive mass. It will take no more than 5 minutes to heat up the tool after switching on. On the handle of the unit, like a real pistol, there is a trigger. With its help, the piston is triggered, creating pressure in the heating chamber, which makes it possible to push the already liquid glue through the nozzle onto the surface of the material to be glued.

The performance of the tool directly depends on the heat chamber, which is located in the barrel of the thermal gun. The size of the chamber and the power of the heating element affect the amount of melted adhesive mass and the rate of polymer melting.

When choosing a tool, be sure to pay attention to the feed mechanism, as it is a capricious design and often breaks down.

The hot gun nozzle shapes the glue and dispenses the flow of molten mass. It is made of metal. Some brands produce tools with different attachments that differ in length and shape.

It is important not to forget to clean the glue from the nozzle after each use of the unit.

The latest models of glue guns are also equipped with illumination, which is important when working with it in a room with poor visibility or even in the dark.

There is a viewing window on the body of the glue gun, an important option for checking the remaining core. Almost all devices are equipped with a folding stand to support the tool with the nozzle down, since it is not recommended to lay the gun on its side, the body can overheat.

The power of the gun is a measure of the rate at which the glue stick melts. The higher the power, the faster the adhesive melts. Professional hot guns from three hundred watts, and amateur up to 150 watts. Some devices are equipped with a power regulator. Heating indicator - a light on the gun body will show when you can start working, and the glue melts to the desired temperature. The melt temperature of the adhesive is also of great importance, as some materials cannot withstand high temperatures.

There are tools for a specific material, but it is more profitable to purchase a unit with a controlled temperature. Any rod melts at 105 degrees, and higher temperatures simply accelerate this process.

Replacement hot gun rods vary in diameter, color and operating temperature. Stickers can be of different lengths (from 4 to 20 cm). The rod diameter is selected according to the configuration of your particular gun.

Colored rods are for masking seams or for decoration. Transparent glue is universal, black is intended for sealing, yellow is used for glass. Even glitter rods have appeared on the market, which opens up more possibilities for decorators.

Preparation for work with a thermal gun

The principle of operation of hot melt guns is the same and you need to know step by step how to use it. This is an electric tool, which means that safety precautions are required. Before each use, you need to inspect the device, there should be no damage to the gun body. Any unnoticed, even the smallest crack, can lead to problems. Next, you should inspect the nozzle, it should not be clogged.

The rod is inserted into the connector until it stops, a new sticker is added only after the first is completely used up.

Straighten the cord before plugging it into a power outlet. Often the length of the cord does not allow the tool to be used freely, in which case an extension cord must be used. There is a switch on the gun body that allows you to adjust the heating temperature of the glue. The heat chamber does not melt the glue after a while, as it needs to warm up. The indicator will show the start of work with the device.

Algorithm for using a hot gun

When the inspection is over, proceed to work with the device. If you use the tool correctly, an excellent result will be guaranteed.

The polymer heats up over time, so do not rush to pull the trigger immediately after turning it on. While the device is warming up, the material is being prepared for work. The surface of the material must be clean and free from grease. The required volume of polymer is adjusted by pulling the trigger. You only need to squeeze out the amount of polymer you need.

The polymer in the molten state keeps the temperature for a few more seconds. During this time, it must be applied to the material and pressed against each other. You need to melt slowly. A large amount of polymer will take longer to bond.

During a break in work, the device must be placed on a stand so that hot glue does not flow into the gun.

Do not exceed the time of using the included instrument specified in the instructions for it. The professional thermo gun can be used for 2 hours, the creative guns must be turned off after 20 minutes. During a break in work, a thin cobweb may form, which is not difficult to remove in a solid state. After finishing work, you should wipe the tip from the remaining glue.

Advantages and disadvantages of a thermal gun

The benefits are numerous. This hot gun provides instant bonding. The adhesion strength is high, it adheres well the same materials to each other, and material combinations to each other. The appearance of the glued surface is excellent in appearance. There is a large palette of glue sticks, you can match the color to any surface. This tool is irreplaceable for fastening work, where it is necessary to do without mechanical stress. It is believed to be environmentally friendly and absolutely safe.

There are few disadvantages of the thermo gun. It does not adhere well to polyurethane with concrete, plaster and cement. And you cannot use this device in a place where a part glued with such glue will be subjected to further heating. For needlework, such a unit is ideal. You can use it to make unique things.
