Claim:
1. An induction heating soldering iron system comprising: a power assembly adapted to deliver power at an output voltage and an output frequency; a magnetic induction heater adapted to receive the power from the power assembly, the heater having a temperature dependent upon the output voltage and the output frequency of the power assembly; a current detector adapted to determine a current flow in the heater; and a control assembly in communication with the current detector, the control assembly is configured to measure a non-zero magnitude of change in the current flow in the heater, configured to measure a non-zero time duration of the change in current flow in the heater, and is adapted to control temperature of the heater in proximity of the Curie point of the heater material by changing the output voltage in accordance with the non-zero time duration and the magnitude of change in the current flow in the heater.
