  • Patent number: 11260465
    Abstract: A multi-process welding machine provides an intuitive user interface to enable a user to select among different welding processes, and to select parameters for a given selected welding process. The multi-process welding machine also provides an arrangement by which a switching module, or DC to AC converter, of an AC TIG unit can be controlled to alternatively supply AC or DC welding voltages or current. Further, a configuration of switches can be leveraged to automatically (or manually) control the polarity of welding cables for different processes and to engage or disengage a wire feeder when, e.g., a MIG welding process is selected, or not selected, respectively. Finally, in an embodiment, the ferrite or magnetic materials used for a main output inductor and an high frequency starting inductor of the welding machine can be combined.

  • Patent number: 10955869
    Abstract: An indication of a type of circuit breaker through which a powered device is connected to a power source is received at a processor. A signal from a sensor indicating a level of power flow from the power source to the powered device is received at the processor. The power flow to the powered device is altered by the processor based upon the received signal and the type of circuit breaker such that the power flow does not cause the circuit breaker to interrupt the power flow to the powered device.

  • Publication number: 20070119268
    Abstract: A mechanical torque wrench including a wrench body defining an elongated interior compartment and a wrench head including a bar extending therefrom being pivotally secured to a first end of the wrench body. A hand grip located on a second end of the wrench body and a set spring is disposed within the wrench body. A pawl is disposed between the bar and the set spring. Rotation of a dial screw in a first direction compresses the set spring and rotation in a second direction allows expansion of the set spring. A set ring is operatively connected to the dial screw and rotatable relative to the wrench body. A resistive element is coupled to the dial screw and produces an output signal that depends on a position of the dial screw relative to the resistive element. A processor converts the output signal into an equivalent torque value for display on a user interface.
