Abstract: Systems and methods for providing welding power supplies with interleaved inverter circuitry are described. In one embodiment, a welding power supply includes, for example, a first inverter circuit and a second inverter circuit that are arranged in parallel. A voltage source or a current source is coupled to a first same node of the first inverter circuit and the second inverter circuit. A filter inductor is coupled to a second same node of the first inverter circuit and the second inverter circuit. The output current of the filter inductor is halved in frequency by disabling one of the first inverter circuit and the second inverter circuit.

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: 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: 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 for initiating and/or terminating 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, the systems and methods disclosed herein implement pulsed cycles with one or more increased output parameters (such as current, pulse width, etc.) in order to jump start a pulsed welding cycle at a cold start (i.e. at initiation of a welding process), and thereby prevent a ball forming and remaining on the end of an electrode wire as the welding process continues. In a similar manner, a pulsed cycle with one or more increased parameters can be used to terminate the welding process, also preventing the ball forming and remaining on the electrode wire.

Abstract: Example welding power supplies include: power conversion circuitry configured to convert input power to welding power, and to output the welding power; and control circuitry configured to: in response to detecting a short circuit between a welding electrode and a workpiece, controlling the power conversion circuitry to increase a current of the welding power; and in response to identifying a predetermined condition that would cause a circuit limiter connected to the input power to trip, control the power conversion circuitry to reduce at least one of an input current of the input power or an output current of the welding power to avoid tripping the circuit limiter.
