20080296276 | Welding-Type Power Source with Integrated Open-Circuit Voltage Controller - A welding-type system and method for operating a welding-type system is disclosed. The system includes a switched power delivery circuit connected to deliver power to output terminals and an open-circuit voltage (OCV) control circuit configured to adjust an operational state of the switched power delivery circuit. A controller is included that is configured to monitor the output terminals to identify an open circuit condition and selectively engage the OCV control circuit to adjust the operational state of the switched power delivery circuit to reduce a voltage of the output power delivered to the output terminals during the open circuit condition. | 12-04-2008 |
20100314371 | SYSTEMS AND METHODS FOR DIAGNOSING SECONDARY WELD ERRORS - A controller for a welding system adapted to determine a value of a weld secondary parameter across a weld secondary component based on a sensed parameter is provided. The controller may also be adapted to compare the determined value to a reference value range and to alert a user to a presence and location of a weld secondary error when the determined value is outside the referenced value range. | 12-16-2010 |
20110180522 | SMART GRID WELDING SYSTEM - Welding system and method permit exchange of data with Smart Grid monitors and/or controllers. The welding systems include a welding power supply configured to convert power between the power grid and the welding power supply. A grid interface cooperates with control circuitry to transmit data to and/or from the grid monitors and/or controllers on the grid side. The control circuitry may control operation of the welding power supply based upon data from the grid. The system may include power generation devices (e.g., engine-drive generators) and energy storage devices (e.g., batteries). The control circuitry may control operation of such devices, the exchange of power between them, and the draw of power from the grid or the application of power to the grid based upon the data exchanged with the grid monitors and/or controllers. | 07-28-2011 |

20140076871 | WAVEFORM COMPENSATION SYSTEMS AND METHODS FOR SECONDARY WELD COMPONENT RESPONSE - A method includes receiving data corresponding to a weld waveform that is generated during a welding operation and determining, based on the received data corresponding to the weld waveform, an overshoot voltage for the welding operation that exceeds an expected voltage level. The method further includes receiving data corresponding to a measured stud voltage and calculating, based on the overshoot voltage and the measured stud voltage, a stud voltage for the welding operation. The method also includes controlling at least one parameter of the welding operation based on the stud voltage for the welding operation. | 03-20-2014 |
20140209587 | WAVEFORM COMPENSATION SYSTEMS AND METHODS FOR SECONDARY WELD COMPONENT RESPONSE - A method includes receiving data corresponding to a voltage level over time and a current level over time. The method also includes determining a first ratio corresponding to a voltage ramp percent or a voltage falling edge percent with respect to a peak in the voltage level and determining a second ratio corresponding to a current ramp ratio or a current falling edge ratio with respect to a peak in the current level. The method further includes determining, based on a comparison between the first ratio and the second ratio, whether to increment, decrement, or maintain an inductance compensation estimation value corresponding to an estimated inductance present in one or more secondary components associated with the welding operation. | 07-31-2014 |
