Hi all,
I'd like to cut some foam inserts for a gun case and I've been looking at building a hot wire cutter, but I'm not comfortable building a power supply from scratch, i.e. wiring up a transformer etc.
I was wondering if it's possible to use something like this http://www.mpja.com/prodinfo.asp?number=16854+PS and using a variable resistor on the DC output?
Any and all ideas are appreciated.
Thanks,
James
