Abstract: An example welding power supply includes: a power input configured to receive alternating current (AC) input power, and power conversion circuitry configured to: convert a first portion of the input power to welding power; output the welding power to a weld circuit; convert a second portion of the input power to preheating power; and output the preheating power to a preheater.

Abstract: Systems and methods for clearing a short during a GMAW-P 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. In examples, if the controller senses an occurrence of a short circuit during the welding cycle (e.g., during the background state), the voltage-controlled process can adjust an output current to increase in order to achieve one or more short state target voltage values. Once the short has cleared (as evidenced by a spike in voltage) and/or a desired short state target voltage value is achieved, the controller can again adjust the output current to decrease until the voltage has returned to a background voltage level.

Abstract: A system for controlling multiple wire feed motors for use in a welding-type system including a push motor controlled to operate at a target wire feed speed and a pull motor disposed in a welding torch controlled to apply a target torque to the fed welding wire. Such a system eliminates shaving and bird nesting of welding wire.

Abstract: Apparatus, systems, and/or methods for mitigating audible noise generated by a welding-type power supply are disclosed. In some examples, the switching frequency of the welding-type power supply may be changed to a frequency that is outside the audible range for humans. This strategy takes advantage of the fact that the observed audible noise is generated by vibrating components within the welding-type power supply that vibrate at a frequency related to the switching frequency. Other noise mitigation strategies include dithering and deactivation of portions of the welding-type power supply that vibrate to generate the audible noise.

Abstract: Systems and methods for providing a constant current controller for use in constant current welding applications are described. In one embodiment, a current controller controls the output current of the welding torch without directly measuring the output current of the welding torch. The current controller controls or sets a current in a primary winding of a transformer in an inverter of a welding power supply to control the output current of the welding torch.

Abstract: Welding-type systems and user interfaces having a color display for displaying physical setup instructions are disclosed. Example interface devices include a process selection input device, a display device, a memory, and a processor. The memory stores weld connection setup graphics and physical welding connections. Each of the plurality of weld connection setup graphics is a graphic of a perspective view of a power supply. The processor, in response to identifying a selected welding process type via the welding process selection input device, displays one of the plurality of the weld connection setup graphics via the display device. The processor detects a physical welding connection made at the power supply, determines, based on the detected physical welding connection, that the detected physical welding connection is incorrect for the selected welding process type, and displays an alert on the display device to indicate an error in the detected physical welding connection.

Abstract: Methods and apparatus to communicate via a welding arc are disclosed. An example welding-type power supply includes a power converter, a weld monitor, and an arc modulator. The power converter outputs welding power to sustain a welding-type arc at a welding-type torch. The weld monitor monitors one or more aspects of a weld performed using the welding-type arc and the welding-type torch, and selects an audio message based on the one or more aspects. The arc modulator configured to modify the welding-type arc to output the selected audio message as a plasma speaker.
