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.
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.
