There is a hard way and there is an easy way LOLMain consideration starts with the length you need for cutting.Next is to check how fast or with how much physical force you need to cut.Last but not least there are limitations and must have things.As a general rule of thumb:Use the thinnest Nichrome wire possible for delicate work and something more solid for big parts, hard foam or parts that have been previously glued together.I always found it much easier to have a longer than required wire in use.One side directly connected, the other with a spring to keep an even tension when the wire is heating up.A good power supply is required, which means you need to be able to control the output voltage and it needs to be able to supply enough current to heat the wire hot enough.A good start is to use a lab power supply rated for an output of 5A.If you need to stick with a simple power supply at a fixed voltage you can calculate what wire and length you need.But again I like to keep it simple and just use the wire directly from the roll and connect a really long section to the power supply - to be safe with an amperemeter between to make sure you won't go over the limit of the power supply.Then simply move and make the length shorter until you get the right temp to get clean cuts.Note length for future reference.So big question: How much in terms of Amps can your adapter suply and do you already have Nichrome wire at hand?If the adapter is strong enough you just need to find the right wire diameter and length ;).
