Abstract: A method of preventing arc flaring events for a welding system is provided. The method includes determining, by a controller, a real-time welding output characteristic of the welding system. The method additionally includes comparing, by the controller, the real-time welding output characteristic to a threshold welding output characteristic. The method further includes controlling an operating characteristic of the welding system in response to a determination that the real-time welding output characteristic exceeds the threshold welding output characteristic.

Abstract: A welding or additive manufacturing power supply includes output circuitry configured to generate a welding waveform, a current sensor for measuring a welding current generated by the output circuitry, a voltage sensor for measuring an output voltage of the welding waveform, and a controller operatively connected to the output circuitry to control the welding waveform, and operatively connected to the current sensor and the voltage sensor to monitor the welding current and the output voltage. A portion of welding waveform includes a controlled change in current from a first level to a second level different from the first level. The controller is configured to determine a circuit inductance from the output voltage and the controlled change in current, and further determine a change in resistance of a consumable electrode in real time based on the circuit inductance.

Abstract: A question and answer game involving the field of criminal justice includes a game board, playing tokens, a die and cards. The board includes two playing tracks upon which the playing tokens move. The tracks consist of playing spaces having indicia thereon that relates to different question and answer categories. The two tracks intersect at various points and the intersection points are connected to a retaining area via a path. The retaining areas are in turn connected to one of the two tracks via a one-way path. The cards contain questions and answers relating to three levels of difficulty. Prior to the start of the game, players choose a particular level of difficulty. Thereafter, a player landing on one of the intersection points has the option of answering a question from a higher level of difficulty than that chosen by the player before the start of the game.
