1、Efficiency advantage:
The heating value of the flame of SG-2 Industrial Gas is 1.7 times that of acetylene gas.The preheating time for boring of SG-2 Industrial Gas is quicker than that of acetylene gas by 50%.The preheating time for cutting is 2 seconds shorter than that of acetylence gaos .The cutting speed of SG-2 Industrial Gas by machine is 15% quicker than that of acetylene gas and 30% quicker than that of propane gas.
The hot correcting speed is 25% quicker than that of acetylene gas.1kg  SG-2 Industrial Gas is equal.to 1.7kg acetylene gas in comprehensive work effeciency.

2、Economical advantage:
The comprehensive cost of using SG-2 Industrial Gas is only about half of that of using acetylene gas and 20% less than that of using propane gas.The cost of gas consuming of acetylene gas is 1.7 times that of SG-2 Industrial Gas in cutting steel works .The cutting seam of acetylene gas is 4-5mm wider than that of SG-2 Industrial Gas.

3、Quality advantage :
The performances of SG-2 Industrial Gas both in cutting and welding carbon steel works are better than that of acetylene gas ,and SG-2 Industrial Gas has the unique advantages in welding and hot correcting the carbon steel works.The tensile strength of the welded seams is 490N/mm. The angle of cold curving is 180 degree.The surface of the steel works cut by SG-2 Industrial Gas is smooth and the sides don’t collapse and there are a little hanging dregs which are easy to be deleted.Using SG-2 Industrial Gas to weld the carbon steel works,the welded parts are anti-oxidize,the welding bath is well ,the molten channel is deep and the steel works can be permeated.Besides,the welded parts have the good formation and strong strength.

4、Environment protectong advantage:
SG-2 Industrial Gas is a green Industrial gas.According to the test made by the Beijing Scientific Research Laboratory of Labor Protection ,SG-2 Industrial Gas is up to the Standard of Industrial Enterprise Design and Sanitation(TJ36-79).It is non-posionous,harmless and non-pollution.The h2s in SG-2 Industrial Gas is less than 0.53mg/m3 ,2800 less than that of acetylene gas,and the PH3 is 4000 less than that ofacetylene gas.

5、Safety advantage:
The explosion limiting range of SG-2 Industrial Gas is only one tenth of that of acetylene gas.The speed of combustion of SG-2 Industrial Gas(in the air)is 3 meters per second,much slower than that of acetylene gas.The burning point is higher than acetylene gas.Another good character of SG-2 Industrial Gas is that it has a lower pressure compared with acetylene gas and doesn’t have back fire.

6、Energy-saving davantage:
The consumption of SG-2 Industrial Gas is 57% less than that of liquefied petroleum gas and the consumption of oxygen is 22% less than that of liquefied petroleum gas.
