摘要: A method and apparatus for precisely controlling the temperature of a heated tip are disclosed. The thermocouple within is sensed at selected rate. compared with preselected set by user. power provided to heat varied cause achieve temperature. If an AC source used, each zero crossing amount that cycle based on same cycle. duration time applied probe desired DC intervals. controls tip. exact thus advantageously controlled provide heating.
