A plasma cutting machine is an apparatus for processing a metal material by means of a plasma cutting technique.
A plasma arc cutting machine is a machine that processes a metal material by means of a plasma cutting technique. The plasma cutting is a processing method which utilizes the heat of a high-temperature plasma arc to partially or partially melt and evaporate the metal at the notch of the workpiece and eliminates the molten metal by the momentum of the high-speed plasma to form the notch, and has the advantages of simple operation, energy saving and the like.
With the gradual maturity of the inverter arc welding power supply technology, the inverter plasma cutting machine is rapidly popularized in the metal processing and manufacturing industries. Because most of the current common inversion plasma cutting machines adopt a high-frequency high-voltage arc striking mode, the electromagnetic interference is very serious, and the inversion plasma cutting machines are not suitable for automatic numerical control cutting and places with strict requirements on the electromagnetic interference. Therefore, the low-frequency plasma cutting machine is silently raised in the international market, the low-frequency plasma cutting machine adopts an arc-drawing mode of 'short-circuiting-separating' an electrode and a nozzle to form a plasma arc, and adopts a relatively simple air valve control circuit, so that electromagnetic interference generated by high-frequency high-voltage discharge is greatly reduced, the environment-friendly and humanized design reduces the harm to human bodies, and the cutting thickness and the cutting effect also have display advantages. However, the low frequency plasma cutting machine is not found in the domestic market for several reasons, which are unacceptable to people:
1. operators are customary to operate the plasma cutting machine in a high-frequency arc striking mode, and worry about no operation can be given to the low-frequency cutting machine when the plasma cutting machine is not used;
2. the low-frequency cutting gun, the electrode and the nozzle are not common in the market, are difficult to purchase and have a slightly high price;
3. the high-frequency plasma cutting machine is purchased all the time, the new equipment is added for maintenance, accessories are universal, and the like, and then the high-frequency plasma cutting machine is purchased.
