Wirestripping and Reflow systems differ from the other styles ofresistance soldering systems, as these systems pass a controlledcurrent through a closed-loop resistive material, creating a hotformedwire that can be used to strip insulating jackets off wires(including Teflon and other PTFE-type materials), used as a hotknifeto melt and trim plastics and waxes, reflow solder balls, andeven perform some wood burning.
