  • Patent number: 11478870
    Abstract: A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

  • Patent number: 11343211
    Abstract: A method for handling a data packet includes a network device receiving the data packet. The method also includes the network device separating first network layer data of the data packet from message data of the data packet. The message data of the data packet includes a source address represented by less than four bytes, a destination address represented by less than four bytes, and a format identifier. The method includes determining whether the destination address of the message data matches an address of the network device or whether the message data indicates a broadcast message. The method also includes the network device processing the format identifier if the destination address of the message data matches the address of the network device or if the message data indicates the broadcast message. The method includes the network device providing the message data to the network device and/or other network devices.

  • Patent number: 11278980
    Abstract: A welding system user interface module includes a front panel comprising a first input device and a first display screen. The welding system user interface module also includes circuitry comprising a memory storing machine-readable instructions, a processor for executing the machine-readable instructions, and communication circuitry configured to receive UI data from the first input device or a second input device of a remote welding system user interface module, and to broadcast synchronized data to the first display screen and a second display screen of the remote welding system user interface module.

  • Patent number: 11253940
    Abstract: A welding regime may implements cyclic short circuits under a closed loop voltage control approach. Upon clearing or imminent clearing of the short circuit, a current recess is implemented. The current recess reduces the current that would otherwise be applied to the weld, resulting in multiple benefits. The recess may be implemented by suspending voltage command signals. Following the current recess, normal control is resumed with the then-current voltage command.

  • Patent number: 11141808
    Abstract: A welding system having a welding power supply coupled to a fume extractor is provided. The fume extractor may be coupled to control circuitry configured to operate the welding power supply. The control circuitry may be configured to begin, terminate or modify the operation of the fume extractor prior to the establishment of a welding arc, after the termination of the welding arc, or both. The control circuitry may be further configured to modify the operation of the fume extractor based upon a type of welding process used.

  • Patent number: 11045891
    Abstract: A method of operating a welding system includes supplying a weld current and a weld voltage to an electrode via a plurality of pulse periods, where each pulse period of the plurality of pulse periods includes a background phase and a peak phase. The method also includes detecting the occurrence of an anomalous cathode event during the background phase of a first pulse period of the plurality of pulse periods based at least in part on when a voltage value of the weld voltage is greater than a detect voltage. The method also includes controlling the weld current to a desired current during a portion of the anomalous cathode event. The portion includes an interval of the background phase of the first pulse period, and the weld current is controlled independent of the weld voltage during the portion of the anomalous cathode event.
