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.

Max operating temperature

Most modern glue sticks melt at a temperature slightly above 100 °C, and a further increase in temperature only makes sense to increase the productivity of the gun: the higher it is, the faster the melting proceeds and the more liquid the glue turns out. There are also high-temperature grades of glue, but most modern pistols are quite capable of coping with them. Therefore, when choosing according to the operating temperature, it is worth considering first of all what materials are planned to be joined. So, for paper and some fabrics, a maximum of 105 – 110 °C is allowed, and with wood, glue guns with a high melting point(200 °C and above) can be used without problems. More detailed recommendations can be found in special sources. At the same time, do not forget that advanced tools can have several temperature modes (see below).

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.
