Features:_x000D_ _x000D_ Made of high-quality zinc alloy, it is durable and has a long service life. _x000D_ High-tech energy-saving and environmental protecting, green and low-carbon, effectively saving 30% - 40% of the gas source. _x000D_ This product can effectively extend the life of the pressure reducer. _x000D_ Secondary decompression keeps the output gas flow stable. _x000D_ Fully automatic energy saving and no need for manual adjustment. _x000D_ With a pressure gauge, the output pressure is visible and intuitive. _x000D_ The scope of application is AR argon and carbon dioxide. _x000D_ One year warranty, quality problems can be replaced during the warranty period, except for man-made damage. _x000D_ _x000D_ Specifications:_x000D_ Condition: 100% Brand New_x000D_ Material: Zinc Alloy, Chrome Plating_x000D_ Energy-saving effect: burnt spot welding up to 1=3 burnt long weld up to 1=2_x000D_ Application: AR argon, carbon dioxide_x000D_ _x000D_ The working principle of gas meter combination:_x000D_ The internal pressure of the cylinder decreases with the decrease of the stored gas volume (the atmospheric pressure principle), so most users lose their blood because of the excessive pressure. According to statistics, as much as 30%-40% waste, after using this energy saver It can effectively control the output pressure and play the role of secondary decompression. When the cylinder pressure is 150 kg or 10 kg, the output pressure is kept between 1.5-2 kg, ensuring stable supply of pressure and eliminating waste of gas. )._x000D_ _x000D_ Package list:_x000D_ 1 * Pressure Reducer_x000D_ 1 * Outlet Thread
