Hot wire machines are named after the finer metal nibs that they utilize. As these pen tips are formed from finely shaped wire forms, they can be used for detailed work much more readily than a solid point machine. Hot wire machines typically consist of a base unit with a power switch and an adjustable temperature setting so that the heat of the pen can be increased or decreased to suit the user’s needs. They have a separate pen that is attached by an electrical cord. Since the heating element is held within the base unit rather than the pen itself, the pens are usually smaller in size and, therefore, easier to hold and maneuver during use. Some manufacturers make “fixed” pens with a specific nib permanently fitted to its own handle, but most machines are also supplied with a pen with a range of different wire nibs that can be swapped as needed. These pens have a pair of holding posts at the tip with a screw mechanism or similar to secure the wire nibs in place and complete the circuit necessary to allow the heat to pass through.
