When cutting high workpiece by wire cutting, the water flow of wire cutting working fluid must be increased. It is best to wrap all molybdenum wires and spray water column at the same time, so as to wash the cut waste. In fact, the height of the workpiece is directly proportional to the parameters of pulse width, pulse interval, power amplifier tube, current and voltage. The higher it is, the greater it needs to be adjusted. The feed speed is inversely proportional to the height of the workpiece. The higher the workpiece is, the slower the feed speed needs to be adjusted. However, there is also a misunderstanding. It does not mean that the higher the workpiece is, the greater the processing current needs to be adjusted. Dalian fast and slow wire cutting processing friends can adjust it in combination with the actual situation. They still need to pursue a stable processing state. If there is a short-circuit current value, just adjust the current to a stable state, and the wire will not break. But for a stable processing state, the fundamental reason is that the pointer on the ammeter is fixed at one position.
