Hi all,
I'm an architecture student and would be extremely grateful for some advice with a tool/machine that im making. Basically i'm creating a large hot wire cutter and need to pass enough power through to heat a 1.6mm, (or 2mm gauge) 1m long nichrome wire to a temperature suitable for cutting. This gauge increases the stiffness which is necessary when dragging through the foam.
This link below displays a hand tool that works in a similar way. This tool uses 0.8mm nichrome wire and comes with an adjustable transformer that can supply 2 Amps @ 16 volts

I've tried using an adjustable power supply at 3 amps, 30 volts with crocodile clips but had no success. I obviously don't have much knowledge in this sector and need to find a way to heat the wire, any help would be great!
