How to convert a regular glue gun to a cordless one

A glue gun is used for quick bonding of various materials. Hot melt glue solidifies literally before our eyes, and at the same time gives a fairly strong connection. The only problem is that the device is powered by the mains. If you periodically need to use a thermal gun in places where there is no outlet, then you can convert the device to 12V.

What you need:

  • A broken network gun will work too;
  • heating element for soldering iron – http://alii.pub/5nsc3l
  • lithium batteries 18650 – 3 pcs. – http://alii.pub/5becfz
  • BMS module 12 V, 10 A – http://ali.pub/4mqfli
  • PVC pipe 50 mm;
  • 1k ohm resistor – http://alii.pub/5h6ouv
  • power connector and plug.

The process of reworking a thermal gun

Since the standard heater wires are short, they need to be lengthened. One wire is laid up to the switch, while the second is led down the handle. The indicator with a resistor will need to be soldered between the switch contact and the second straight wire.

Now you need to make the battery case. For this, a piece of plastic pipe is heated and stretched until the plastic hardens. As a result, a module with a battery is placed in the resulting elongated case, you can read more here – https://sdelaysam-svoimirukami.ru/7988-kak-sdelat-karmannyj-generator-dlja-zarjadki-telefona-kotoryj-vsegda-gotov-k- rabote.html

The power wires must be routed through the hole.
