I have a Steinel Gluematic 3002 hot glue gun. This glue-gun itself I’m fairly happy about, but the mains cable is much too stiff. This causes it to tip over from the force of the wire.
Therefore I decided to replace the cable with something more flexible. I came across some silicone rubber wiring. This is very flexible, but also is heat resistant. This means it will not get damaged if I accidentally touch it with the hot nozzle.
After opening the glue gun it turned out to be very easy to replace the cable. The strain relieve was not molded to the cable and the wires to the heating element where just crimped to the other wire.
This modification makes it much easier to work with.
