Application

Argon is a rare gas that is colourless, odourless, and heavier than air. Applications for argon include use as a shielding gas for special welding problems and sensitive materials (titanium, niobium, tungsten, etc.), use as a filling gas for windows and lamps, use in spark erosion spectrometry and plasma processes. Gas is easy to handle in a small, light pressure can, while the disposable container allows for aluminium recycling when finished.
