How to use a hot glue gun?

A hot glue gun is a tool that has become popular due to its simple design, while its bonding strength is top notch and does not take much time. This device without reservation is called folk, as it is in almost every home.

The main advantage of this device is simplicity and ease of use, and consumables cost a penny. And the device itself is not expensive, but it opens up a lot of opportunities. Heat gun is in the arsenal of builders, helps fix engineering communications, seals, glues, fills the seams. Used by needlewomen, florists, designers, giving the opportunity to glue a variety of accessories, make all sorts of designs.

Radio amateurs actively use glue guns when repairing microchips and wiring.Even artists saw decorative value in a polyurethane melt, creating drawings from glue mass. In domestic use, this thing is not interchangeable, with the help of such a gun you can restore even broken dishes.

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

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

The hardened polymer is elastic and resistant to moisture. Polymer adhesive is harmless.

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

Spare glue enters the pushing mechanism hub, getting into a special pipe - rubber receiver, and from it the edge of the rod rests on the heating chamber, in which the polyurethane melts, turning into an adhesive mass. To heat the instrument after switching on, it will take no more than 5 minutes. On the handle of the unit, like a real gun, there is a trigger. With it, the piston is started, creating pressure in the heating chamber, which allows pushing the already liquid glue through the nozzle onto the surface of the material that needs to be glued.

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

The nozzle of the hot gun gives the glue its shape and dispenses the flow of molten mass. It is made of metal. Some brands produce tools with different nozzles, differing in length and shape.

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

On the case of the glue gun there is a viewing window; this is an important option for monitoring the rest of the rod. Almost all devices are equipped with a folding stand, to support the tool with the nozzle down, because they do not recommend laying the gun on its side, the body can overheat.

The heat gun power is an indicator of the melting speed of the glue stick. The higher the power, the faster the glue melts. Professional hot pistols from three hundred watts, and amateur up to 150 watts. Some devices are equipped with a power regulator. The heat indicator - a light on the gun body, will show when you can start work, and the glue melts to the desired temperature. The temperature of the melt glue is also of great importance, since some materials do not withstand high temperatures.

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

The principle of operation of the hot melt guns is the same and you need to know step by step how to use it. This is an electric tool, so safety is required. Before each use, you need to inspect the device, on the body of the gun should not be any damage. Any small crack, though unnoticed, can lead to problems. Next, you should inspect the nozzle, it should not be clogged.

Straighten the cord before plugging it into the wall outlet. Often the length of the cord does not allow free use of the tool, in which case you need to use an extension cord. On the body of the gun there is a switch that allows you to adjust the temperature of the heating 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.

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

The polymer heats up over time, so do not rush to pull the trigger immediately after switching it on. While the device is heated, the material is prepared for work. The surface of the material must be clean and free of grease. The desired amount of polymer is regulated by pressing the trigger. You need to extrude only 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. Must need to slowly. A large amount of polymer will require more time to glue.

You can not exceed the time of use of the included toolspecified in the instructions to it. Professional thermogun can be used for 2 hours, guns for creativity 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. Having finished work, it is necessary to wipe a tip from the remained glue.

The benefits are numerous.Such a hot gun provides instant bonding. The bonding strength is high, well glues the same materials together, and the combination of materials with each other. The appearance of the glued surface has an excellent appearance. There is a large palette of glue sticks, you can choose a color for any surface. This tool is not replaceable during fastening work, where you need to do without mechanical impact. It is believed that it is environmentally friendly and absolutely safe.

There are some flaws in the thermogun. It badly sticks polyurethane with concrete, plaster and cement. And you can not use this device in a place where the part, glued with such glue, will be subjected to further heating. For needlework such a unit fits perfectly. With it, you can make unique things.
