Just curious to see what's inside a mains-powered glue gun. Two main parts - a mechanical pusher and an electrical heater.

    Very interesting

    Yes, that is exactly the case. Two distinct layers of insulation.

  3. Avataaar/Circle Created with python_avatars Richard B says:

    The alloy is a380 aluminum, not zinc.

  4. Avataaar/Circle Created with python_avatars Richard B says:

    Actually it is the positive temperature coefficient that makes it self regulating. Resistance increases when it gets hot, limiting the current.

  5. Avataaar/Circle Created with python_avatars Richard B says:

    PTC heaters actually have a resistance decrease (negative temperature coefficient) before a temperature dependent increase ( positive temperature coefficient) until reaching a Curie Point where resistance increases rapidly.

    Hello good evening and congratulations for the video … I'm Italian and thanks to this video of yours, very detailed on hot guns (there are few on the net), I gladly follow you 🙂 🙂 🙂 I wanted to ask you: where can I find and to buy the replacement of the silicone rubber? because mine broke … thanks 1000 if you answer 🙂 🙂 🙂

    please help me, I bought a glue gun yesterday. this is the first glue gun for me. I have a problem. No glue comes out of the tip of the gun. I tried to blow air inside the metal chamber when it got cold but i found out that it is blocked. there is a metal yellow copper blocking the cone part where the glue supposes to come out. I could see it with light and a zoom camera. can you help me. i just want if the chamber should be blocked in case of temperature room and open when it is hot. would you please try to put a needle in the tip to your glue gun and see it the needle will go through easily or it is blocked as mine,
