Hey Gil

That power supply is the one I use. You know it works well with the inconel.

You can buy Chrome Nickel fishing leader wire at Walmart. It's 69# test and 0.018 inch. It comes in a 25 foot length for less than $2. Works like a champ.

This is the stuff at Walmart.

My question is: wich wire to use for foam cutting and what kaind wire diameter to use. Whati is difference between this wires.

I am using .018 inch, but I see a lot people using between .016 and .020 inch. I have a 115V to 25.2V, 2 Amp step down transformer. My AC voltage going into my transformer measures 124.9 and I'm seeing a little over 28 volts at my cutting wire. My power supply uses a 1 Amp fuse and so far it hasn't blown using .018 inch wire.

My problem is wire I have on hand now breaks too frequently. Anybody recommend something that holds up well without breaking? Reason it breaks is I cut foam manually using guides the wire makes contact with and moves along during the cutting.

Do you cut using wood templates or similate?? I used to cut wings for Rc planes using wood templates, and the wire used to break due to friction. Then I learned a simple trick: you shoul cover the edge of the template with adhesive aluminium tape, wich is used for isolating air conditing installations. Then the wire will run smoothly

I am looking for Nichrome 6 ohm/foot wire.
I tried find it from HobbyLobby, Home depot, etc..
Ebay doesn't have 6 ohm/foot.

Anyone can help me?

I think this site can help you to find what you are looking for:
wires.co.uk : Bare Nickel Chrome / Nichrome Section
they have almost all the kinds of wires, and many more helpful items.

For anyone that needs "small" quantities, one strand of bicycle brake cable works perfectly for me.
It measures +/- 20 ohm/meter. The twist does go away after the first use.
