摘要： PROBLEM TO BE SOLVED: To provide a pulse arc power supply and pulse arc welding equipment using this power supply, with which welding with a satisfactory finish can be performed even in case sheet metals are welded. SOLUTION: The pulse arc power supply in this invention is characterized in that a current from the power supply part 1 reaches a welding wire 7 via a reactor 32 for pulse period during a pulse period and during the short circuit period of the welding wire 7 and a material 8 to be welded, and during periods except the above, via a reactor 31 for base period, whose inductance is larger than that of the reactor 32 for pulse period. The path of this current can be changed over between the reactor 32 side for pulse period and the reactor 31 side for base period by that a reactor change-over switch 2 is closed or opened by a reactor change-over circuit 42 according to a signal from a short- circuit judgement circuit 43 and by connecting or disconnecting the reactor 32 for pulse period. Consequently, the increasing and the decreasing speeds of the current at the time of a pulse can be made speedy and a pulse waveform can be sharpened.

摘要： PURPOSE:To easily and surely prevent a line stoppage by the deposition of a wire by impressing a welding voltage for short time and welding the vicinity of a deposition zone after detecting that a consumable electrode is deposited to a base metal side with the inertia in weeding after completion of welding. CONSTITUTION:In the consumable electrode type arc welding method by impressing a welding voltage by feeding a wire 5 and executing the welding of a base metal 10 by forming an arc, an arc is stopped by making the welding voltage zero simultaneously with the completion of welding. On the other hand the wire 5 is extended by the inertia in feeding, deposited to a base metal 10 side and stopped. This deposition is detected by a deposition detecting circuit. The wire 5 is then cut B near a deposition zone by impressing the no-load voltage of about 50V and a current at some delay time preferrably. Thereafter a welding torch is moved to the other welding place to start the succeeding arc welding. With said method, the stoppage of an automatic welding line due to the deposition of the wire 5 to the base metal 10 and chip of the welding completion time is surely prevented and the slag adhesion to the wire 5 is prevented as well to better an arc starting property.
