Argon is a colorless, odorless and tasteless inert gas which has no toxic properties. A member of the rare gas chemical family, argon constitutes less than 1% of the atmosphere and is heavier than air. Liquid argon at — 302°F is clear and odorless. Argon has several different uses in several industries, it is most used as a shield gas for arc welding.
Features
- Colorless, odorless, nonflammable inert gas
- Inert to all materials at all temperatures and pressures
- Heavier than air, argon will collect in low-lying areas, ducts and drains
- An asphyxiant (does not support life)
- Lower thermal conductivity than most other gases
- Easy forming of welding arc without reacting to metal components
- Creates fluid welding pool when combined with other gases
