Abstract

PURPOSE: To start and stop welding securely in safety, by providing a starting circuit which sends start and stop signals, a timer circuit which determines the time of electric feed, and a flip-flop which receiving a switch signal by availing a synchronizing pulse as a clock pulse.
CONSTITUTION: Welding power source AC200V is inputted to OP amplifer 9 and D flip-flop 28 of starting circuit 27 via transformer 5, rectifying circuit 6 and OP amplifier 7, and a pulse synchronizing with the power source is also inputted to D flip-flop 29 and D flip-flop 27 of timer circuit 35. As welding is started with foot pedal, limit switch 30 is turned on to hold the output of D flip-flop 29 to H and that of AND gate 34 to H, then-electric feed is started. The period of the electrical feed is determined by starting the timer circuit with the output of D flip-flop 29. When the foot pedal is ceased, limit switch 30 is turned to OFF to change the output of D flip-flop 29 from H to L, and transistor 38 is turned to ON to change output terminal OUT of timer IC36 from L to H.
