20090159572 | Plasma Cutter Having Thermal Model for Component Protection - 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. | 06-25-2009 |
20090222804 | EMBEDDED FIRMWARE UPDATING SYSTEM AND METHOD - A system and method is described for updating firmware in a welding or plasma cutting system. A removable memory device containing updated firmware code and a set of execution instructions is interfaced with one or more component boards. The execution instructions are executed on a processor of the welding or plasma cutting system to load the updated firmware code stored on the removable memory device into memory of the welding or plasma cutting system via an interface, generally overwriting the old firmware code. | 09-03-2009 |
20130319987 | REMOTE POLARITY DETECTION AND CONTROL FOR WELDING PROCESS - A system includes a welding torch, a welding power supply unit, a remote device, and control circuitry. The welding power supply unit is configured to supply power to the welding torch. The remote device is coupled between the welding torch and the welding power supply unit. Additionally, the remote device is configured to detect a polarity of a welding operation. The control circuitry is configured to determine if the detected polarity is appropriate based on one or more welding parameters. Further, the control circuitry is configured to adjust the polarity of the welding operation. | 12-05-2013 |
20140312022 | PERSONALIZED INTERFACE FOR TORCH SYSTEM AND METHOD - There is provided a system and method for quick identification and selection of torch processes based on a profile scheme. In an illustrated embodiment, a profile selectable via a one-click process may define operational parameters for one or more torch processes. Multiple profiles may be identified by corresponding labels that are visible on the face of the system. Furthermore, in an illustrated embodiment, the profiles and associated torch processes may be automatically stored in the system upon user configuration of the operational parameters. For example, in one embodiment, the user may select a profile and configure a welding process. Upon changing an operational parameter, it may be automatically saved to the selected profile and process. Reselection of that profile may recall the last used process and its associated parameters. The operational parameters of other configured processes may then be retrieved by selecting the desired process within the selected profile. | 10-23-2014 |
