For a start, it is important to choose the power source. My last Petamentor works with a 12V 5A power supply. This is the ideal setup for puller and sufficient heating of the heater.
The power supply is simply screwed to the bottom of the board. Switching on and off is controlled by a separate button, which is screwed with a printed bracket. You can find the connection of the power supply in the video below. This work is very quick and easy. If you don’t know how to do something, visit the community forum and go through the chapters, or post a new question.
