It simple words, gas is blown at high speed from a nozzle while an electrical arc melts the element and compressed air to blow away the molten element. metal cnc table is extensively used in pressure vessels, automobiles, locomotives, chemical appliances, engineering machinery, steel buildings, nuclear industry, general machinery, ships, and other industry areas.
IGOLDENCNC has summarized the following common problems and treatment suggestions, hoping to give you some reference and help.
1. Keep the cutting nozzle channel clean. The cutting nozzle channel should always be kept clean and smooth, and the dirt in the hole should be cleaned with a needle at any time.
2. Treatment of flame extinguishment After ignition, when the preheated oxygen adjustment valve is turned to adjust the flame, if the flame extinguishes immediately, the reason is that there is dirt in each gas channel or the nozzle of the suction pipe is not in tight contact and the outer and inner parts of the cutting nozzle Mismatched mouth. The nut on the suction pipe should be tightened; when it is invalid, the suction pipe should be removed, the dirt in each gas channel should be removed, and the gap between the outer and inner sleeves of the cutting nozzle should be adjusted and tightened.
3. The flame of the nozzle and the cutting torch is not strictly coordinated. Although the flame is normal after ignition, the flame is extinguished immediately when the cutting oxygen adjustment valve is opened. The reason is that the cutting head and cutting torch are matched, and the joint is not strict. At this time, the cutting nozzle should be tightened. When it is invalid, the cutting nozzle should be removed and gently use fine sandpaper. Grind the mating surface of the cutting tip until it fits tightly.
4. Choose the right cutting nozzle according to the thickness of the cutting workpiece. When assembling the cutting nozzle, the inner nozzle and the outer nozzle must be kept concentric to ensure that the cutting oxygen jet is located in the center of the preheated flame. When installing the cutting nozzle, pay attention to tighten the cutting nozzle nut.
So What Exactly is Plasma Cutting?
plasma machine cnc is a common method used by a whole range of industries to cut iron, stainless steel, aluminum and other metals using a plasma torch. Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening. The gas can be shop air, nitrogen, argon, oxygen. etc. This elevates the temperature of the gas to the point that it enters a 4th state of matter. We commonly think of matter having three states: a solid, a liquid, and a gas but scientist refer to plasma as the fourth state. Matter changes from one state to the other through the introduction of energy, such as heat.

How Does a Plasma Cutter Work?
The plasma cutting process is a thermal cutting method. Which means that is uses heat to melt the metal instead of mechanically cutting it.
The overall mechanics of the system is always the same. Plasma cutters use compressed air or other gases, such as nitrogen. Ionisation of these gases takes place to create plasma.
Typically, the compressed gases come into contact with the electrode and then ionise to create more pressure. When the pressure builds up, a stream of plasma is pushed towards the cutting head.
The cutting tip constricts the flow to create a stream of plasma. This is then subjected onto the workpiece. As plasma is electrically conductive, the workpiece is connected to the ground through the cutting table.
As the plasma arc contacts the metal, its high temperature melts it. At the same time, the high speed gases blow away the molten metal.
