Glue guns with heat indicator
Heating indicator
— indicator, usually light, signaling the heating of the gun. Usually, it notifies both that the process is in progress and that the operating temperature has been reached — for example, at the end of heating, the light bulb changes colour. This makes it easier to keep track of the instrument's condition. The heating indicator is often combined with the network indicator (see the relevant paragraph).| heat indicator | clear | Save List |
