Build Detail of Heater Element

This is just about right. Now the connection of copper directly to nichrome doesn't work, it burns out. So instead of going directly from nichrome to copper - use a piece of steel wire, and wrap the nichrome around the steel wire. No solder - solder would melt.

We added solid fence wire as an intermediate between the nichrome wire and the 200C wire. Direct contact of nichrome to copper burns out the copper. Nichrome simply wraps around the fence wire for a secure connection.
