  • Waveform compensation systems and methods for secondary weld component response
    Patent number: 9506958
    Abstract: 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.

  • CONTROLLED SHORT CIRCUIT WELDING SYSTEM AND METHOD
    Publication number: 20160288235
    Abstract: A welding system and method provide for generating a controlled waveform for welding power output, the waveform comprising a plurality of successive peak phases followed by a short circuit between a welding wire electrode and an advancing weld puddle. Each then present peak phase is regulated based upon at least the immediately preceding short circuit to control the short circuit that will occur following the then present peak phase. Some embodiments permit regulating at least one waveform phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur, and regulating at least one short response phase based upon at least the immediately preceding short circuit to control the next short circuit that will occur.

  • CONTACTING REMOTE SUPPORT (CALL HOME) AND REPORTING A CATASTROPHIC EVENT WITH SUPPORTING DOCUMENTATION
    Publication number: 20160224405
    Abstract: Responsive to detecting a failure in a computer system determined by receiving a trap from at least one component integrated in the computer system, a notification to a recipient may be transmitted. A service ticket is created associated with the failure. One or more other problem events occurring during the failure is detected and an indication that the other problem events occurred during the failure is recorded. Notifying the recipient during the failure, of the one or more other problem events, is prevented. Responsive to detecting a resolution of the failure, the service ticket is updated with the other problem events with the indication that the other problem event occurred during the failure.

  • Hybrid pulsed-short circuit welding regime
    Patent number: 9403231
    Abstract: Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.

  • Method and Apparatus For Welding With CV Control
    Publication number: 20160207136
    Abstract: A method and apparatus for welding is disclosed. The output is preferably a cyclical CV MIG output, and each cycle is divided into segments. An output parameter is sampled a plurality of times within one or more of the segments. The CV output is controlled within the (at least one segment in response to the sampling. The parameter is output power, a resistance of the load, an output current, an output voltage, or functions thereof in various embodiments. The control loop is preferably a PI or PID loop. The loop may be applied only within a window. The set point may be taught or fixed. The system can be used to weld with a controlled arc length.

  • Waveform compensation systems and methods for secondary weld component response
    Patent number: 9387550
    Abstract: 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.

  • DABBING PULSED WELDING SYSTEM AND METHOD
    Publication number: 20160144444
    Abstract: A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

  • FAUCET INCLUDING CAPACITIVE AND ULTRASONIC SENSING
    Publication number: 20160024766
    Abstract: A fluid delivery apparatus includes a spout, an ultrasonic sensor, and a capacitive sensor. The ultrasonic sensor is configured to detect the presence of a user adjacent the spout when enabled. The capacitive sensor is configured to define a capacitance sensing field in an area near the spout and also to detect a presence of a user. A controller is coupled to the capacitive sensor and the ultrasonic sensor. The controller is programmed to detect the presence of a user in the capacitance sensing field based on an output signal from the capacitance sensor. The controller is also programmed to enable the ultrasonic sensor in response to detecting the presence of the user in the capacitance sensing field with the capacitive sensor, thereby reducing the amount of power used by the ultrasonic sensor.
