Hi,
I recently bought 18 gauge Nichrome wire for the purpose of cutting a Sofa cushion foam in half (split the cushion foam, in effect make the cushion half as thick). Length of wire I will heat is 3 feet (cushion is almost 2 feet wide)
I have what I need to adjust the current from 1 to 12 amps. Also, I have a chart for amps relating to temperature. Example: Apx. 6.5 amps for
600 degrees F. for 18 gauge Nichrome wire.The only information I was unable to find was the recommended temperature for cutting foam with this type of wire.
Thank You in advance, John
