    Abstract: A welding apparatus is configured to obtain values of one or more real-time operating parameters associated with the welding apparatus. Using the values of the one or more operating conditions, the welding apparatus is configured to determine a dynamic duty cycle of the welding apparatus, given the present/current operating conditions of the welding apparatus.

    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.

    Abstract: A welding machine includes a main transformer having first primary winding, a second primary winding, and a secondary winding; a power board configured to receiving mains power and to convert the mains power to converted power to be input to the main transformer; a switch having an input connected to an output of the power board, a first output connected to the first primary winding of the main transformer, and a second output connected to the second primary winding of the main transformer; and a control board configured to control the switch to be arranged in one of (i) a first configuration in which the converted power is supplied, in series, to a first primary winding of a main transformer switching and a second primary winding of the main transformer, and (ii) a second configuration in which the converted power is supplied, in parallel, to the first primary winding of the main transformer and to the second primary winding of the main transformer.

    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.
