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.

Methods and apparatus to synergically control a welding-type output during a welding-type operation

A method and apparatus for providing welding type power is disclosed. The output is cyclical, and is a controlled voltage output during the background and/or peak and a controlled current output during the transition up and/or down. During the controlled current portion the output is responsive to output voltage.

Method and apparatus for pulse welding

Welding system and method permit exchange of data with Smart Grid monitors and/or controllers. The welding systems include a welding power supply configured to convert power between the power grid and the welding power supply. A grid interface cooperates with control circuitry to transmit data to and/or from the grid monitors and/or controllers on the grid side. The control circuitry may control operation of the welding power supply based upon data from the grid. The system may include power generation devices (e.g., engine-drive generators) and energy storage devices (e.g., batteries), The control circuitry may control operation of such devices, the exchange of power between them, and the draw of power from the grid or the application of power to the grid based upon the data exchanged with the grid monitors and/or controllers.

Smart grid welding system

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 a voltage of the welding-type power and a wire feed speed based on the control signal.

In certain embodiments, a system includes a welding-type system including circuitry configured to receive direct current (DC) power directly from a distributed DC bus, to generate a current using the received DC power, and to isolate the welding-type system from the distributed DC bus.

A method and apparatus for providing welding-type power is disclosed and includes a means for communicating.

Weld cell system with communication

A welding-type system and method for operating a welding-type system is disclosed. The system includes a switched power delivery circuit connected to deliver power to output terminals and an open-circuit voltage (OCV) control circuit configured to adjust an operational state of the switched power delivery circuit. A controller is included that is configured to monitor the output terminals to identify an open circuit condition and selectively engage the OCV control circuit to adjust the operational state of the switched power delivery circuit to reduce a voltage of the output power delivered to the output terminals during the open circuit condition.

Welding-type power source with integrated open-circuit voltage controller

A method includes receiving data corresponding to a voltage level over time and a current level over time. The method also includes determining a first ratio corresponding to a voltage ramp percent or a voltage falling edge percent with respect to a peak in the voltage level and determining a second ratio corresponding to a current ramp ratio or a current falling edge ratio with respect to a peak in the current level. The method further includes determining, based on a comparison between the first ratio and the second ratio, whether to increment, decrement, or maintain an inductance compensation estimation value corresponding to an estimated inductance present in one or more secondary components associated with the welding operation.

Waveform compensation systems and methods for secondary weld component response

A method and apparatus for providing welding-type power is disclosed and includes a means for communicating and a means for locating a cable. A welding power supply has a controller, a power circuit and a weld cable locator module with a cable locator output connected to the controller, the power circuit, and/or a weld cable connection. The distal end of the cable is located, and the proximal end is connected to the power supply. An identifying signal is provided to the proximal end and transmitted to the distal end where it is detected. A pendant with a cable sensor and a transmitter responsive to the cable sensor can be provided. The cable sensor can include an RFID reader and/or a bar code reader.
