    Abstract: A welding-type system includes a welding-type power supply configured to generate output power for an arc welding process and a controller. The controller calculates a representative duration of a plurality of short circuit events and/or arc events during the arc welding process. Each short circuit event and/or arc event comprises a transitional phase, an intermediate phase, and an end phase. The controller calculates a sum of a duration of the transitional phase, a duration of the intermediate phase, and a duration of a ramp down time from a target current of the intermediate phase to a target current of the end phase associated with a given short circuit or arc event. The controller controls the welding-type power supply to adjust a duration of the transitional phase, the intermediate phase or the ramp down time associated with the given short circuit event such that the sum is within the threshold range of the representative duration. Additionally or alternatively, the controller maintain a duration of the end phase less than a predetermined value.

    Abstract: Disclosed is a welding system configured to perform additive manufacturing, particularly by employing an additive manufacturing tool to build up a part by employing welding-type programs. In some examples, control circuitry controls the additive manufacturing tool to operate in a first welding-type program of a plurality of welding-type programs in response to a determination that the measured temperature is below a first threshold temperature of one or more threshold temperatures, and control the additive manufacturing tool to operate in a second welding-type program of the plurality of welding-type programs in response to a determination that the measured temperature is above the first threshold temperature.

    Abstract: Systems and methods for auto-tuning a MIG welding process are disclosed. A welding-type power supply may include a power conversion circuitry configured to convert input power to welding-type power; and a controller configured to control the power conversion circuitry based on a plurality of operating parameters. The operating parameters may include an inductance parameter, a slope parameter, or a wet time parameter. During the welding process, in order to control the power conversion circuitry, the system may measure an output from the power conversion circuitry, and may update the inductance parameter, the slope parameter, or the wet time parameter.

    Abstract: A fume extraction system is designed for metal working and other applications. The fume extraction system includes one or more motors and/or adjustment devices to control fume suction airflow. One or more sensors may monitor a condition of the welding torch to determine a level of porosity of a weld. Control circuitry is operable to receive signals from the one or more sensors and/or power supply in order to determine the level of porosity. The control circuitry can compare information in the signals to a list of values associated with weld porosity to determine whether the level of porosity is within a desired range. In some examples, the control circuitry can control the fume extraction system to adjust suction airflow based on the determined level of porosity.
