Abstract: In certain embodiments, a welding system includes an interface with 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, 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, a third input element configured to receive an input relating to whether the parameter of power and the rate of advancement of the electrode are automatically set, and a color display device configured to display the parameter of power and the rate of advancement of the electrode. The welding system also includes control circuitry configured to adjust and display on the color display device the parameter of power and the rate of advancement based at least in part on a selected diameter setting for the electrode and a selected material thickness setting for a work piece when the third input element is activated, and to control the parameter of power and the rate of advancement based on the adjustment of the parameter of power and the rate of advancement.

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: 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.

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: Systems and methods are provided for visually displaying thermal duty cycles. Remaining weld time may be determined in a welding-type apparatus based on one or more parameters that correspond to at least one of: a real-time measurement corresponding to ambient conditions, a real-time measurement corresponding to power consumption, and a thermal profile of the welding apparatus. The information relating to the indication of remaining weld time may be presented to an operator of the welding-type system. The welding-type power supply may be shut off when a shut off threshold is satisfied.
