Argon (Ar)

Argon (Ar) High Purity Gas

Messer’s high-purity argon gas is a crucial component in welding, electronics, and scientific research. As an inert shielding gas, argon enhances weld quality in metal fabrication, particularly in MIG and TIG welding applications. In the electronics industry, it provides a controlled environment for semiconductor production, while in laboratories, it is used for gas chromatography and spectroscopy. With a reliable supply chain and various packaging options, Messer delivers premium argon solutions designed for precision and efficiency.

Most Commonly Purchased Argon Gases

Messer supplies gases in a range of purity levels and formats to meet industrial, research, and precision needs. With delivery options including cylinders, dewars, bulk storage, and on-site generation, we ensure consistent quality, performance, and efficiency.

ARGON MCP16 T

Argon (Ar, LAR), although comprising less than one percent of the atmosphere, is an important industrial gas. One of its unique properties is its absolute inertness. Argon is colourless, odorless, tasteless and nontoxic.

PURELINE Ar ARGON L

Pureline Ar is high-quality pure argon delivered in dedicated cylinders to ensure product integrity and consistency. It is ideal for light sheet metal welding, all thickness on steel, chrome-alloy, stainless steel, titanium, aluminum, copper and their alloys in GMAW/MIG and GTAW/TIG processes. Pureshield Argon reduces porosity, oxidation and other defects commonly caused by inconsistencies in the shielding gas.

Argon Industrial Liquid

Argon (Ar, LAR), although comprising less than one percent of the atmosphere, is an important industrial gas. One of its unique properties is its absolute inertness. Argon is colourless, odorless, tasteless and nontoxic.
