I have a large resistor that goes in my J-Head extruder. It's grey, and it came with the extruder. I'm uncertain as to what grade of wire I need to solder to it. It being one of the elements of the system that heats the hottest, I would think that it would be important to find out what sort of wire is the correct kind to use on it, since heating elements require alota lot of electricity.
Also does the solder type I use matter?
