  • Method and Apparatus for Pulse Welding
    Publication number: 20210086281
    Abstract: A method and apparatus for providing welding type power is disclosed. The output is cyclical, and is a controlled voltage output during the background and/or peak and a controlled current output during the transition up and/or down. During the controlled current portion the output is responsive to output voltage.
    Type: Application
    Filed: December 8, 2020

  • System and Method for Short Arc Welding
    Publication number: 20200316704
    Abstract: An example method of controlling a short circuit welding process includes: setting a heat target for at least a portion of a short state; monitoring output parameters during the short state; calculating a measured heat from the measured output parameters; comparing the measured heat and the heat target; adjusting a pinch current in a subsequent short state in response to at least one comparing from at least one previous short state; and repeating these actions.

  • System and method for short arc welding
    Patent number: 10695856
    Abstract: A method and apparatus for short circuit welding is disclosed. They reduce the current prior to the short clearing by adjusting waveform parameters in response to past cycles. One or more parameter of the output is monitored and compared to one or more targets, and future waveform parameters are adjusted so that the monitored parameters are more likely to reach the one or more targets.
