Apparatus and methods for automatically recalibrating an output current range of a user output current control encoder (140, 240) of an auto - reconnect welding/cutting device (100). When an input power type connected to an auto - reconnect device is changed, the calibrated range of the user output current control encoder (e.g., output control knob) is automatically transformed in response to the auto - reconnect device sensing at least one characteristic of the input power type. As a result, when a user adjusts the encoder to its maximum full-scale setting, too much current will not be drawn by the auto - reconnect device which would cause a circuit protection component (e.g., a circuit breaker or a fuse) associated with the input power type to trip. Instead, the current that is drawn when the encoder is set to the maximum full-scale setting is no more than about a rated current of the circuit protection component. |
