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).
Battery voltage
Nominal voltage of the battery installed in the corresponding tool (see "Power supply"). A higher voltage allows you to achieve more power and intensity of heating, but in general this parameter is more of a reference — in fact, it can only come in handy when looking for a spare / replacement battery or an external charger.
Battery capacity
The capacity of the battery installed in the respective tool (see "Power supply").
The higher the capacity, the more energy the battery can store and the longer it can power the tool without recharging. At the same time, the actual battery life of work depends on many other factors (primarily the power of the gun). Therefore, only models with very similar characteristics can be compared with each other in terms of capacity, and even in such cases, the comparison may not be correct.
However, this information may appear when looking for a spare or replacement battery: it is desirable that its capacity is not lower than that of a regular one.
Operating time
The duration of the device on a fully charged battery. Accordingly, when using different capacities and interruptions, this value may change, therefore it is very conditional.
Charging time
The required time to charge the battery of the device from a fully discharged to a "combat state".
