Nichrome wire is commonly used in packaging machinery to seal plastic bags. A current is applied to it and it heats up and used to seal the bag. We have rolls of the stuff to replace the wires in the sealing bar when they get old and break. Try an industrial packaging supply house. You are looking for the NiChrome wire used in a machine called a "Drop Sealer"

Pottery Suppliers For Nichrome

Pottery & glass working kilns (of the electric variety) use nichrome wire in the elements.
Check in your area for a large supplier. They usually have the wire available by the foot.

Just a thought - what about using stainless steel wire leader (shark leader)? Too much resistance or?? Thouht I'd seen that suggested or sold for the same purpose. Is there any problem using it as a substitute?
Thanks Jim

High Seas.....I suspect that using the stainless would not work......well okay, maybe if you supplied a 100 amps or so.....Nichrome wire is the way to go and all the old fashioned appliance repair places have it.

Thank you again.
