Low-voltage electrical appliances - moving contacts

Program overview

The welding process is closed-loop controlled by a microcomputer, and the system has high integration and strong functions. Constant voltage or constant current control mode, when the grid voltage fluctuates within ±15%, the controller automatically compensates. 64 sets of independent welding procedures, multi-pulse energized welding. Phase sequence detection and phase loss detection capability with three-phase power supply; when the phase sequence is reversed or missing phase, when the pressure or water flow is insufficient, the welder will give an alarm prompt and stop working. With single spot welding, continuous spot welding.
