  • Patent number: 11027356
    Abstract: An engine-driven welder generator is controlled based upon power draw for welding and other applications. Once a welding arc is initiated, the power draw is monitored. The engine speed, and therefore the power output of the generator, may be increased or maintained based upon the power draw. The power draw may include both welding power draw and auxiliary power draw. The engine speed is increased in increments. The initial engine speed and subsequent increments may depend upon particular welding processes or regimes.

  • Patent number: 11027352
    Abstract: Systems and methods for welding are described. The welding system can include, for example, a power source, a computer, and a welding torch. The computer and the welding torch can be operatively coupled to the power source. The power source controls a wire feed and one of a current or a voltage to the welding torch. When the welding torch is performing pulsed welding, the computer is configured to receive a weld signature. The computer is configured to synthesize features from the weld signature and to analyze the features for each pulse of the weld signature to determine whether particular limits have been exceeded or met. If particular limits are exceed or met, a weld fault condition is triggered which causes the welding system to stop or to modify the pulsed welding operation, and/or which causes the welding system to send out communications relating to the triggering of the weld fault condition.
