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.
Sticks length
The length of the glue stick for which the gun is designed. In fact, we are talking about the optimal length: many models allow you to charge both longer and shorter rods, but it is most convenient when the length of the consumable corresponds to the manufacturer's recommendations.
Feed rate
The maximum glue flow rate that the gun can provide is, in fact, the peak performance of the tool.
In general, indicators up to 10 g / min can be attributed to low, up to 20 g / min — to medium, more than 20 g / min — to high. The larger the scale of the planned work, the higher the glue supply rate is desirable for them; on the other hand,
high performance may be overkill in cases where little adhesive is required. However, if the tool is bought for simple household tasks, this indicator can be ignored.
Heating time
The average time it takes the glue gun to reach operating temperature (in models with multiple modes, it is usually indicated for the maximum temperature). A more “fast” tool allows you to significantly save time; on the other hand,
rapid heating significantly affects the price and power consumption.
Number of temperature modes
The number
of temperature adjustments provided in the design of the glue gun.
The simplest models have one mode and are able to heat up only to the maximum operating temperature. The presence of several modes allows you to adjust the instrument to a specific situation; this is especially useful when working with materials that are sensitive to high temperatures. At the same time, the more modes, the more extensive the adjustment possibilities. And the most advanced option is smooth adjustment, which allows you to choose any value in the range from minimum to maximum. On the other hand, it is almost impossible to accurately set the temperature in such models, while in pistols with several fixed settings, on the contrary, each mode corresponds to a strictly defined temperature.
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.
