摘要： An improved welding power supply control circuit is disclosed. The control circuit, which incorporates a microprocessor, simultaneously adjusts the power supplied to a welding electrode and the speed of the electrode, in accordance with a selected power/speed relationship table or curve. The power/speed relationship of a selected table can be further modified manually, as by a potentiometer, to optimize the weld. Feedback circuitry senses the frequency of the weld and the weld voltage, to regulate the power and to modify the slope of the voltage/current output curve, respectively.

摘要： The specification describes a mechanism for controllably advancing material such as wire to a work station. The mechanism includes two frusto-conical shaped wheels mounted in a face to face relationship so that the wire is pulled through the nip formed by a rotation of the wheels. One wheel has an associated bias adjustment means which is adapted to vary the pressure exerted by one wheel on the other. A flexible wire guide, and an adjustable spool holder form part of the mechanism.
