So when I was building my foam cutter, I did not want to wait for a roll of nichrome wire to arrive in the mail. I started looking around my house for something else I could try out. I know that stainless steel conducts electricity but not very well and I happened to have some 1/16th tig wire in my shop. This stuff is so handy to have around and I have used it for many projects in the past, most notably my make your own springs in seconds
instructable. I decided to try it out and it works. You sometimes have to adjust the resistance by extending the wire longer because this is pretty hard on the power supply. I can tell if the resistance is too low because the power supply sounds like a weightlifter going for the world record. The wire does not get red hot but will cut foam easily enough. The best part about this is because it doesn't get red hot it can easily hold any shape you bend it into.
