Please start this section by viewing the Electrical Theory Section.

You will have a better appreciation for the mechanics behind your circuit and power supply requirements. MANY questions will be answered if you read this section first...

Then continue on to the Power Supply Requirements Section where you will be able to determine the necessary electrical power rating.

Proceed to this section first which discusses the theory and electrical circuitry of your hot wire foam cutter.
This page contains a very easy calculator which will help you estimate your circuit requirements to help guide the purchase of your power supply.
An alternate source of power for those that wish to learn how to create the ultimate portable cutting device!
The discussion on this page also will help you retrofit for a fixed voltage power supply. The theory is exactly the same.
