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: Systems and methods for setting welding parameters are provided. For example, in certain embodiments, a method includes receiving an input relating to a change in a parameter of welding power of a welding system via a welding system interface. The method also includes displaying a graphical representation of an acceptable range of values for the parameter of the welding power on a display device of the welding system interface, wherein the acceptable range of values is based on other parameters of a welding process being performed by the welding system. The method further includes constraining subsequent manual inputs relating to changes in the parameter of the welding power to the acceptable range of values.

Abstract: Methods and apparatus to synergically control a welding-type output during a welding-type operation are disclosed. An example welding-type power supply includes a power conversion circuit configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch; a communication circuit configured to receive a control signal from a remote-control device during a welding-type operation; and a control circuit configured to synergically control at least two of a voltage of the welding-type power output by the power conversion circuitry, a current of the welding-type power, or a wire feed speed.

Abstract: Systems and methods are provided for selecting welding schedules in welding-type torches. A welding-type torch configured for use during welding-type operations, with the welding-type torch comprising an input device configured for setting a welding-type parameter, such as welding schedules, associated with a welding-type device that is used in conjunction with the welding-type torch during the welding-type operations. The welding-type device may be a welding-type power source. The welding-type torch is connected to the welding-type device via a welding-type connector, with the setting of the welding-type parameter occurring via the welding-type connector and without requiring a change to structure of the welding-type connector. The welding-type parameter is set to one of a plurality of available values, with the input device causes setting the welding-type parameter to a specific value from the plurality of available values only in response to receiving a corresponding specific input associated with that value.

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.
