A method includes ramping down a welding current, generated by a power supply, that reaches a welding zone via a welding circuit, storing inductive energy from the welding circuit that is generated as a result of the ramping down to obtain stored energy, and selectively feeding the stored energy to the welding circuit.

A method of monitoring a heating operation on a component by a flame torch, including the steps of producing a flame with the flame torch, rotating the component with respect to the flame so that a circular weld is created on the component, and providing a first sensor that is operatively engaged with the component so that the first sensor monitors rotation or non-rotation of the components.

An arc start adjustment device adjusting an arc start procedure in a welding process comprises an obtainment unit that obtains welding data indicating a welding state during or after a welding process, and a procedure adjustment unit that adjusts the arc start procedure such that the cycle time of the welding process is shortened based on welding data obtained by the obtainment unit.

A pulse arc welding profile control method, a control device, a welding system, a welding program, and a welding power supply are provided in which, even when a pulse arc welding method is used, protruding change information is extractable at high accuracy without influence from a welding current or an arc voltage having a pulse shape. An electric change amount detected at the time of weaving includes, as a parameter, at least one among a welding current detection signal and an arc voltage detection signal, takes a predetermined period as one period, calculates an average value of the electric change amount in each one period, and extracts, on the basis of the average value, the protruding change information in a groove to follow a welding line.

Systems and methods for setting the polarity of welding-type power provided by a welding-type power supply. The output polarity may be automatically selected based on one or more selectable welding parameters. The automatically selected polarity may be overridden based on operator input.

Apparatus and methods for welding asset tracking with heartbeat monitoring are disclosed. In some examples, a welding asset tracking system may comprise an asset tracking network of tags, hubs, and/or gateways retained by welding assets within a welding area. The welding asset tracking system may generate heartbeat signals that certain welding assets may require for normal operation, so as to ensure the welding assets are used in appropriate welding contexts and/or welding areas. In some examples, information obtained from the asset tracking network may be used to determine whether one or more heartbeat signals should be discontinued.

A method of determining weld quality includes the step of providing a reference weld signature having a first shape. A weld signature of a welding parameter is captured, wherein the weld signature of the welding parameter has a second shape. The first shape is automatically compared to the second shape and a weld signature shape difference between the first shape and the second shape is determined. A weld fault condition is determined based on the weld signature shape difference.

Systems and methods for tracking and associating welding-type data with selected welding jobs. A welding job from a plurality of welding jobs stored in memory of a welding-type power supply may be selected, and welding-type data collected while a particular welding jobs is selected is associated in memory with the selected welding job. Welding-type data associated with the plurality of welding jobs may be displayed and managed.

A method and apparatus for providing welding-type power is disclosed. It includes an input circuit, a dc bus, an output circuit, and a control module. The input circuit receives power and provides an intermediate signal to the bus. The output circuit receives the dc bus and provides an ac welding-type output. The output circuit includes a half-bridge output inverter with at least first and second switches. The output inverter further includes an output control circuit. The output control circuit provides freewheeling paths that includes control switches, the output, antiparallel diodes. The control module has a four quadrant control module that provides control signals to the half bridge output inverter and provides modulating control signals to the first and second output control switches. The modulating signals cause the output control switches to be turned on and off multiple times to control a rate of change of output current.

A method and apparatus of communicating control signals to a welding power source from a remote location includes a welding system operated by control signals transmitted by a wireless remote control that can be remotely located from the welding power source. A plurality of welding parameters in the welding system are set and adjusted in response to wireless command signals transmitted to a receiver that is connected to the welding power source via a connection port and is further connected to a controller in the welding power source. In this regard, an operator is able to quickly and efficiently control a welding system from a remote location, with no more cables than are necessary to perform the intended task.
