摘要： A heating system includes a heating head assembly configured to move relative to a workpiece. The heating system may also include a temperature sensor assembly configured to detect a temperature of the workpiece and/or a travel sensor assembly configured to detect a position, movement, or direction of movement of the heating head assembly relative to the workpiece, and to transmit feedback signals to a controller configured to adjust the power provided to the heating head assembly by a power source based at least in part on the feedback signals. In addition, certain control techniques that take into account certain parameters, such as physical parameters of the workpiece being heated, the heating process parameters, and so forth, may be implemented.

摘要： A device providing a temperature control and/or monitoring and a method for use of the device are disclosed. In the disclosed method and device, a controller receives a minimum temperature value and a maximum temperature value of a temperature range to be measured. The controller correlates a known output signal range of a temperature sensor to the temperature range to be measured. Further, the controller receives an output signal from the temperature sensor, and generates a measured temperature value based on the output signal of the temperature sensor.

摘要： Engine driven power supplies with output reduction are disclosed. An example engine-driven welding power supply for providing a welding-type output includes an engine, a generator mechanically linked to the engine, power conditioning circuitry, and a controller. The generator generates output power based on mechanical input from the engine. The power conditioning circuitry converts the output power from the generator to welding-type power based on a commanded welding-type output. The controller reduces a welding-type output of the power conditioning circuitry from the commanded welding-type output by an amount proportional to a difference between a speed of the engine and a commanded engine speed while monitoring the difference between the speed of the engine and the commanded engine speed, decreases the welding-type output until the difference between the speed of the engine and the commanded engine speed decreases, and increases the welding-type output as the difference between the speed of the engine and the commanded engine speed decreases until the welding-type output equals the commanded welding-type output.
