The recommended welding thickness range for this gas mixture is 4-28mm.
OneGas 90/10 is a shielding gas mixture composed of 16% Carbon Dioxide, 3% Oxygen in Argon. It is specifically designed as a general-purpose gas mixture for MIG welding applications. This mixture is suitable for both short arc and spray transfer modes and is compatible with solid wires used on mild steels. The presence of CO2 allows for increased weld penetration, while the Oxygen enhances arc stability, resulting in cleaner and more precise welds. It is recommended for welding thicknesses ranging from 2-22mm.
Nitrogen is commonly used as a purge gas in welding stainless steel tubing. Nitrogen acts as a safeguard to prevent flammable substances from coming into contact with oxygen and potentially causing combustion. In addition to welding, Nitrogen’s inert properties make it a reliable choice for creating controlled atmospheres and ensuring safety in various processes in industries such as manufacturing, food packaging, plasma cutting and heat treating processes, purging and pipeline testing, calibrate and pressure testing gauges, metal casting and refining processes to remove impurities and gases from molten metals and also plastic forming processes.
Carbon Dioxide (CO2) is commonly used for MIG welding of carbon and alloy steel, but it can also be used in combination with stainless steel and gas shielding flux cored wires.
Apart from welding, Carbon Dioxide has a range of applications. It is used in the beverage industry for carbonation, in the conservation of liquids, in agriculture for enhancing plant growth, in chemical manufacturing, and in the production of paints, varnishes, and foam rubber. Its versatility and availability make it a widely used gas in various Industrial industries.
SS 98 is a mixture of 2% Carbon Dioxide and 98% Argon. This low oxidizing mix is suitable for MIG welding in the short circuit, pulsed modes, or spray on all stainless and duplex materials within a welding thickness range of 3-10mm. To select the appropriate filler metal, it is advised to identify the specific type of stainless steel being welded. Many commonly used alloys in stainless steel welding are specifically designed to enhance the fluidity of the weld puddle. The most frequently encountered stainless steel base metals include 304 and 316, while 309 and 316 are among the most commonly utilized welding wires for stainless steel.
SS 02 is a gas mixture composed of 2% Oxygen and 98% Argon. This mixture has a medium active gas content, making it suitable for MIG welding of stainless and duplex steels. It can also be used for GMAW (Gas Metal Arc Welding) of most high alloy and austenitic stainless steel, covering a range of material thickness. The recommended welding thickness range for the OneGas SS02 is 1-3mm.
Acetylene is a colorless and highly flammable gas, it is a strong, safe, and easy-to-use gas. The heating qualities of Acetylene are particularly advantageous for applications such as thermal spraying, brazing, gouging, and welding. It is also used in atomic absorption flame spectrometers and as an air gas blend.
In Acetylene/Oxygen gas welding and cutting it is renowned for its high melting point, fast preheating and piercing times in localized cutting. Acetylene/Oxygen flame can burn at temperatures as high as 3,500 °C, making it suitable for various applications.
The optimal ratio of Oxygen to Acetylene for this process is 1.2:1, ensuring efficient combustion and maximum flame temperature, in comparison to Oxygen/LPG cutting which requires a higher ratio of 4.3:1, this makes the Acetylene/Oxygen combination more efficient.
Liquefied Petroleum Gas (LPG) is a flammable gas which is non-toxic and colourless. It is intentionally odourised with a special chemical agent so that it is easy to detect a leak.
15kg Cylinder - Used for fueling Forklifts.
45kg Cylinder - Used for Oxy/LPG Cutting and running industrial heaters, fans or blowers.
Food Grade Argon
Food Grade Argon is mainly used as a preservation Fsupplement gas within the hospitality industry.
Food Grade Carbon Dioxide (CO2) plays a crucial role in the food industry, specifically in preserving the quality of beverages and other products. Its primary purpose is to maintain the freshness and visual appeal of these products. It is used at various stages of production, such as carbonating beverages, preserving wine and fruit juices, preventing oxidation in beer products, and aiding in cooling and freezing processes. Food Grade CO2 is also safe to handle, as it is non-flammable, odorless, colorless, and non-toxic.
Food Grade Nitrogen gas is extensively utilized in various food preservation applications. It is commonly used for chilling and freezing, controlled atmosphere storage, and even fumigation of grains. Nitrogen gas helps create a protective atmosphere, preventing spoilage and extending the shelf-life of food products. It is used for processes such as blanketing (to prevent oxygen exposure), modified atmosphere packaging (MAP), sparging (to remove unwanted gases), food freezing and chilling, and grain fumigation. When combined with Carbon Dioxide and Oxygen, Nitrogen gas is particularly effective in modified atmosphere packaging (MAP) applications, further enhancing food preservation capabilities.
