What are the advantages of Gas cutting machine?
Gas cutting machine has the advantages of light weight, high strength, corrosion resistance, compact structure, convenient operation and safe use. Gas cutting machine uses medium-pressure acetylene and high-pressure oxygen for cutting work. It can cut steel plates with a thickness of more than 8 mm, mainly for straight line cutting, and also for circular cutting with a diameter of more than 200 mm, as well as bevel and V-shaped cutting. It can also use the power of the Gas cutting machine and the matching additional devices to perform flame quenching and plastic welding. The surface roughness of the cut steel plate can reach 12.5. In general, no surface cutting can be performed after cutting.
How to deal with common faults of Gas cutting machine?
1. Damage to the cutting tip and electrode: If the cutting tip of the Gas cutting machine is improperly installed, not tightened, or the water-cooled cutting torch is not connected to the cooling system, the loss of the cutting tip will increase.
Solution: Adjust the correct gear of the equipment according to the relevant parameters of the cutting workpiece, and check whether the cutting torch and the cutting nozzle are firmly installed; the water-cooled cutting torch should circulate the cooling water in advance.
2. The input air pressure is too high: if the input air pressure of the Gas cutting machine is greater than 0.45MPa, the air flow with excessive pressure after the plasma arc is formed will blow away the concentrated arc column, disperse the energy of the arc column and weaken the cutting strength of the plasma arc.
Solution: Check whether the pressure adjustment of the air compressor is properly adjusted, and determine whether the pressure of the air compressor is consistent with the pressure of the air filter pressure reducing valve. Adjust the adjustment switch of the air filter pressure reducing valve during the operation of the air compressor. If the air pressure gauge does not change, it means that the air filter pressure reducing valve is out of order and should be replaced in time.
What is the working principle of Gas cutting machine?
The thermal cutting of the flame separation material produced by the mixed combustion of combustible gas and oxygen, also known as oxygen cutting or flame cutting. During gas cutting, the flame preheats the material to the ignition point at the cutting point, and then injects an oxygen stream to make the metal material violently oxidize and burn, and the generated oxide slag is blown off by the airflow to form a cut. The oxygen purity used in the Gas cutting machine should be greater than 99%; the combustible gas generally uses acetylene gas, but also can use petroleum gas, natural gas or coal gas. The cutting efficiency with acetylene gas is the highest, the quality is better, but the cost is higher.
