By far the greatest number of heating element designs involve the use of round wire close-wound on an arbor or mandrel and then stretched to form a helix of at least twice the close-wound length. Proper, the next step in designing such elements is to choose a size of wire which will operate at the desired temperature and which can also be coiled to fit within the physical space limitations of the device. In most cases, some precedent will have been established as a basis for determining the proper wire size. Lacking prior experience,
