  • Patent number: 11904418
    Abstract: Provided is a welding-type power source, comprising power conversion circuitry configured to convert input power to welding-type power, a user interface comprising a first input device, a second input device, and an output device, and control circuitry. The control circuitry is configured to, in response to a first input via the first input device, control the output device to output an indication that the welding-type power source is in a preconfigured state, set predetermined ones of welding-type parameters to respective predetermined values, set a welding current, when there is an input from the second input device, to a value indicated by the second input device, and set the welding current, when there is not an input from the second input device, to one of: the default value when the default welding current has not been changed, or a welding current that has been changed previously via the second input device.

  • Publication number: 20220126389
    Abstract: An example welding-type system includes: power conversion circuitry configured to convert input power to welding-type power; an interface configured to: receive a selection of a parameter from a plurality of parameters; and receive a selection of a value for the selected parameter; and control circuitry configured to: in response to the selection of the parameter from the plurality of parameters, control the interface to output a visual indication of an effect of changing the parameter on at least one of a welding electrode, a quantity of discontinuities in the weld, a magnitude of a discontinuity in the weld, or a quantity of inclusions in the weld; in response to a change in the value of the selected parameter via the interface, control the interface to change the visual indication of the effect based on the change in the value; and control the power conversion circuitry based on the value.
