摘要： A pulse arc welding machine in which, when any one of the material and diameter of a consumable wire electrode or the shielding gas used is varied, a peak current value and pulse width of a pulse current applied between a consumable wire electrode and a base material being welded as well as a wire feeding speed required for optimum welding conditions are automatically adjusted. The welding machine includes a consumable wire electrode, a wire feeding unit for the wire electrode, a base current source, and a pulse current source for supplying a pulse current superposed on the base current. A sensor detects the arc discharge voltage between the consumable electrode and the base material being welded. The quantity of heat applied to the electrode is corrected by comparing an output detection signal produced by the sensor with a preset arc voltage and then producing a pulse width instruction signal in response to the difference signal for setting the pulse width of the pulse current. When the detected arc voltage is large, the quantity of heat applied to the electrode by the welding current is decreased and the wire feeding speed is increased, while when the arc voltage is small, the quantity of heat applied to the wire electrode is increased and the wire feeding speed decreased.

摘要： A pulse arc welding machine in which the repetition frequency of the pulse currect is unaffected by the frequency of the power source and the mean value of the pulse current applied can be accurately controlled over a broad range while the arcing is maintained stable. A pulse peak current supplying circuit is connected in series with an arcing region formed between a consumable wire electrode and a material to be welded between the output terminals of a standard direct current source while a base current supplying circuit is connected in parallel with the pulse peak current supplying circuit. The pulse peak current supplying circuit and the base current supplying circuit are both composed of a switching element such as a transistor coupled in series with an inductive element. Diodes are provided for suppressing high voltage transients in the circuit.

摘要： A pulse arc welding machine in which current pulses are periodically applied between a welding wire and a base method. A voltage is measured between the welding wire and the base metal to determine if whether an arc to a short-circuit exists therebetween. If a short-circuit exists, a new current pulse is delayed until the arc is reestablished.
