Abstract: Disclosed example power supplies, user interfaces, and methods are provided for simple and intuitive setup for configurable and/or default settings for a welding power source and/or wire feeder. The welding parameters may correspond to a default and/or factory setting that represents empirically adduced values for a particular welding procedure (e.g., based on material type, electrode diameter, welding process and/or tool, etc.). The welding parameters may additionally or alternatively be configured for a particular purpose. Once a configurable setting has been selected, the configurable setting controls the system output. Furthermore, once a configurable set of welding parameters has been established, the operator may return to the default settings by resetting the welding parameters.

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.

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: A welding system includes an interface having a first input element configured to receive an input relating to a parameter of power delivered to a welding torch from a welding power supply and to alternatively receive an input relating to a thickness of a work piece, a second input element configured to receive an input relating to a rate of advancement of an electrode delivered to the welding torch from a welding wire feeder and to alternatively receive an input relating to a diameter of the electrode, and a third input element configured to receive an input relating to a welding process type. The welding system also includes control circuitry configured to automatically adjust the parameter of the power and the rate of advancement of the electrode based on the input relating to the welding process type selected with the third input element when the second input element receives the input relating to the diameter of the electrode.

Abstract: Systems and methods are provided for indicating schedules in welding-type torches. A welding-type system may comprise a welding-type power source, a welding-type torch, driven by the welding-type power source, and a welding-type connector configured for connecting the welding-type power source to the welding-type torch. The welding-type torch may comprise one or more indication components configured for providing, to a user of the welding-type system, indications relating to at least one of operations of the welding-type torch, status of welding-type operations, or welding-type parameters. The one or more indications comprise an indication of a present value of a particular welding-type parameter that pertains to configuration of the welding-type power source; and the one or more indication components are configured to provide the indication of present value of the particular welding-type parameter without requiring a change to structure of the welding-type connector.

Abstract: A power supply for welding, cutting and similar operations includes a dual two-switch forward converter. The converter has two inverter circuits coupled in parallel but controlled to provide output power in an interleaved fashion. To avoid “walking” of the circuits (which could result in different duty cycles and imbalance of the load sharing), control signals are determined and applied to a first of the inverter circuits, and “on” times of the first circuit is monitored, such as by augmenting a counter to determine the number of clock cycles the first circuit is “on”. The same duration is then used for commanding output from the second inverter circuit. The duty cycles of both circuits is thus ensured to be the same regardless of changes in the total output power.
