Main control unit structure of longitudinal seam automatic welding machine

The whole machine control adopts PLC programmable controller as the main control unit, independent welding torch walking speed regulation circuit, "adjustment/automatic" function to ensure that the welding speed adjustment, the welding torch lifting action and the adjustment of the welding torch position can be realized in the adjustment state. The "automatic" state realizes the automatic completion of the welding process. With speed digital display, welding length digital preset and other functions. It adopts industrial-grade touch screen display and operation, with powerful functions and friendly man-machine interface. The controller is controlled by the PLC, the adjustment parameters are displayed by liquid crystal, and the control output pulse is driven by the servo motor driver. (Integration of oscillator controller and whole machine control system).
