Abstract
This disclosure sets out a soldering wand control system. With a wand having a heated tip, a heater element and a thermostat for measuring tip temperature, an output signal of tip temperature is provided. Using an analog to digital converter, tip temperature is transmitted to a CPU along with a set point temperature. The CPU also connects with a binary switch which is toggled to input an operator generated signal for changing tip temperature. In the preferred form, the binary switch is a reed switch which is physically mounted for easy operation by an operator moved magnet. This enables easy input of a binary signal for changing the circuit and its operation. In one form, the binary switch is a reed switch mounted on a printed circuit board within the cabinet and is magnetically sensitive by virtue of an external magnet which causes operation.
