The heating element coils are designed for low watt density loading of the
surface area of the wire (40 to 55 watts per square Inch). A heavier than
standard gauge wire Is used, with the longer coil stretch maintaining required
resistance for a given wattage. This results inn lower coil operating temperature
which ellminates glow under standard operating conditions because
greatly increased surface

The heating coil is strung on a specially designed, 20 gauge galvanized or
