Abstract: An example welding power supply includes: power conversion circuitry configured to convert supply power to welding current and to output the welding current to at least one of a shielded metal arc welding (SMAW) electrode, a gas tungsten arc welding (GTAW) electrode, or a gouging torch; a voltage sense circuit configured to measure an output voltage of the power conversion circuitry; and control circuitry configured to: determine a droop slope based on an arc control parameter; determine a reference voltage corresponding to an amperage parameter; set a target current by adjusting the amperage parameter based on the droop slope and based on a difference between the output voltage and the reference voltage; and control the power conversion circuitry using a current-controlled control loop based on the target current.

Abstract: Systems and methods for remote control of a weld schedule of a welding power supply are disclosed. In some examples, a remote device is provided for monitoring or controlling the welding power supply, which controls and delivers power to one or more welding tools (e.g., a welding torch) and/or accessories (e.g., a wire feeder). The remote device includes a user interface to receive one or more inputs, which are provided to a control circuitry configured to transmit signals to or receive signals from the welding power supply via a remote transceiver. In some examples, the signals include data corresponding to one or more weld schedules.
