One of the foot pedal spot welding machine circuits
This circuit uses the accurate delay characteristics of the CD4541 integrated circuit A to achieve constant welding power
-on time, thereby ensuring the welding quality when welding the same weldment. For different welding parts, the power-on delay time can be easily
changed by adjusting the potentiometer RP to meet the welding quality requirements. The light-emitting time of the light-emitting diode VL represents the power-
on welding time. In the picture, so is the foot switch.
