Input current is the most important parameter for plasma cutting machine during cutting process, it will determine the thickness and the cutting speed, that is, cutting capacity. If the cutting current is increased and increase the arc diameter, the incision will be wider. If the cutting current is increased and increases arc energy, cutting capacity is increased, the cutting speed increases. From this perspective, we should select correct cutting current and corresponding nozzles according to the thickness of the material. Ensure that the voltage constant. To adjust the voltage, it must be based on the needs of the plate, according to the needs to cut out the perfect product.
