Max. power consumption

The highest power consumed by the glue gun during operation. Usually, such power is required by the device for a short time, to warm up to operating temperatures; while maintaining the temperature, the energy consumption is much lower.

The higher the power consumption, the less, usually, the heating time (ceteris paribus); on the other hand, the consumption of electricity and the load on the power grid depend on this characteristic. However, even in the most high consumption models, the maximum power usually does not exceed 1 kW, which allows you to connect to a regular household outlet without any problems; and to estimate the heating time, it is better to look at the characteristics directly claimed by the manufacturer. As a matter of fact, data on maximum power consumption is rarely required in fact, usually when connected to a generator, stabilizer or other equipment where it is necessary to accurately estimate the load.

Functions

Anti-drip system. This feature prevents the adhesive from dripping when the spray gun stops working. This is implemented by moving the rod deep into the case, as a result of which it does not continue to melt further in the heated heater and does not drip onto the table, floor, etc.

Heating indicator. A pointer that notifies the user of the heating process. Usually, it looks like a light bulb that is on while the tool is heating up, and when the operating temperature is reached, it goes out or changes colour. This allows you to easily determine the moment when you can start work, without fear that the rod has not melted enough. The same pointer can play the role of an indicator of network connection.

Network connection indicator. A pointer indicating that the instrument is connected to the network. Usually performed in the form of a light bulb, which in some models also works as a heating indicator. The mains connection indication, among other things, makes it easier to identify certain problems (for example, breaks in the power cord or non-working sockets).

Backlight. Own lighting system — usually in the form of a small light bulb under the nozzle. This feature greatly simplifies work in low light conditions: the gun itself illuminates the gluing site, eliminating the need for the user to use external li...ght sources.

Detachable power cord. A mains lead that is connected to the gun using a quick-release fastener, usually in the form of a socket with a pair of pins and an appropriate plug. This feature not only makes it easier to store and transport the tool, but can also come in handy during work: if the length of the wire is not enough, and little glue is needed, the gun can be detached and quickly brought to the right place. Of course, there is no question of long-term work without a wire, but removing the tool from the cord can be more convenient than looking for another outlet, and the battery life of some models is enough for 5 to 10 minutes of work.

Sticks included

The number of glue sticks supplied with the gun.

The presence of rods allows you to use the tool "out of the box" without buying additional materials. At the same time, complete consumables, by definition, have the optimal length and diameter.
