Gas – Air Liquide


WrightBuilt Engineering is an agent and distributer for Air Liquide gasses in the Lake Macquarie area.

The Air Liquide group is the world’s largest industrial gas company. It specialises in industrial gases including oxygen, nitrogen, carbon dioxide and argon, as well as acetylene, hydrogen, helium, plus a range of specialty gases.

Gases for Industrial Applications


ARCAL shielding gases deliver optimum performance for root shielding, plasma cutting and arc welding of stainless, carbon and alloy steel, aluminum, copper and other materials. ARCAL products meet or exceed current and anticipated changes to A 5.32/ISO 14175 standards. The application of these gases allows high welding and cutting productivity, exceptional quality of welded joints and better working conditions.

Arcal 1 = Welding of Aluminium and stainless steel

Arcal 5 = Welding of Mild Steel and bisalloy

Arcal 14 = Welding Of Body Metal

Carbon Dioxide CO2

In addition to its well-known and extensive use as the carbonating and dispensing medium in the beverage industry, carbon dioxide has numerous other uses in many different industries. For example, in metal fabrication operations, CO2 is widely used as a shielding gas in a semi-automatic welding process. In the food industry, CO2 is employed for processing, packaging, transportation and refrigeration of meat products, frozen foods, dairy products and as an inert atmosphere over perishable products. CO2 is commonly used to neutralize process and waste water streams. CO2 is available in single cylinders or multi-cylinder packs.

Nitrogen N2

Nitrogen is used in purging applications for heating, ventilation and plumbing industries. Large volumes of nitrogen are required by oil refineries and petrochemical industries for purging and blanketing operations. Nitrogen is also being used at a sharply increasing rate by the food industry. In its liquid form, it is employed to quick-freeze a wide variety of perishable foods, some of which cannot be successfully frozen by conventional methods. In its gaseous form, nitrogen is used in storage facilities for fresh produce to delay ripening and deterioration. Nitrogen is available in single cylinder and multi-cylinder packs.

Oxygen O2

Oxygen is commonly used in industrial applications in conjunction with acetylene and other fuel gases in processes such as metal cutting, welding, flame hardening, scarfing, cleaning, hard-facing, etc. Oxygen USP is available for customers licensed to dispense medical oxygen. Oxygen is available in single cylinders or multi-cylinder packs.

Acetylene C2H2

Acetylene is a standard fuel gas used in conjunction with oxygen for welding metals and cutting steel, and for allied oxy-acetylene processes for the heating, forming and treating of metals. Acetylene is available in cylinders.

Argon Ar

Argon is an inert gas that is often used in shielded arc processes for welding aluminum, stainless steel, bronze and copper. In these processes, argon is used as a shielding gas, either in pure form or in combination with predetermined percentages of oxygen, carbon dioxide or helium, depending on the metal being welded. The shielding gas provides an inert atmosphere during welding to prevent oxidation or other chemical change of the metals that would be detrimental to the weld. Argon is also used for inerting in other industries such as wine making and food applications, and is available in single cylinders or multicylinder packs


ALIGAL single and mixed gases are designed to satisfy demanding quality requirements of the food industry. They are used extensively in Modified Atmosphere Packaging (MAP) of a wide variety of food products. By preserving the freshest characteristics of foods, and by extending shelf life
