Abstract
A system is provided that includes a torch power unit. The torch power unit includes a monitor and/or control configured to determine a temperature of a component of the torch power unit based on the one or more inputs without a direct temperature measurement of the component. A method of operation is provided that includes receiving one or more inputs associated with a device, and estimating a temperature of the device based on the one or inputs without directly measuring temperature of the device. A tangible machine-readable medium is provided that includes code for determining a thermal capacity of the device, code for determining a thermal resistance of the device, and code for determining a temperature of the device based on thermal capacity and the thermal resistance method.
