摘要： An automatic presettable welding system which enables the user to preset the arc voltage and wire feed speed to precise predetermined values without either energizing the wire with arc voltage or initiating the wire feed. A meter is supplied with an appropriate signal so the readout corresponds to the desired wire feed speed or the desired arc voltage and these same signals are supplied to wire feed speed or arc voltage comparative circuits which then function to energize a wire feed motor or an arc welding power source to the precise wire feed speed or arc voltage indicated on the meter. Means are provided for controlling the acceleration of the wire feed drive motor and a controlled initiation of the arc voltage at the beginning of each weld. Overload, over-voltage and under-voltage or over or under wire feed speed and other protective circuits are provided with appropriate delays in the functioning thereof to insure fully automatic and satisfactory welding.
