Here you will find a basic discussion of electricity and the theory behind Hot Wire Foam Cutter power supplies
In this brief tutorial I outline the basics on using a multimeter and testing your circuit’s resistance. Which is measured in Ohms.
Knowing the resistance of your circuit will help you determine the power supply requirements. But it will also help determine if you are overloading/underloading your power supply
See the Troubleshooting Section for more help.
This is a full tutorial for calculating power supply requirements for your hot wire foam cutter.
Check out the Calculations Page for more information.
There are manufactured resistors available that you can purchase and apply to your circuit.
But this tutorial shows you a few simple techniques to save some money and create your own in-line resistor.
