ARCAL™ Gases

ARCAL™ offers a full range of high-quality, ready-to-use shielding gas solutions.

Compliant with ISO 14175 and AWS-A5.32 standards, our pure, stable gases and mixtures are strictly prepared and packaged for safe handling. Whichever product you choose, you will receive the high-quality shielding gas that can be mixed on-site or delivered in cylinders.

ARCAL™ products offer guaranteed quality 

Our state-of-the-art mixer provides consistent quality of the shielding gas mixture and delivers highly reliable performance without the use of moving parts or electrical power. No buffer tanks or analysers are needed.

High productivity and overall cost management is obtained by:

  • High welding speeds
  • Excellent penetration profiles
  • Extra low spattering
  • Excellent pool appeal

High quality results are due to:

  • Controlled impurity level
  • Consistent and homogeneous mix
  • Extra low humidity and oxygen levels particularly in plasma or TIG processes


Four ready-to-weld argon mixture solutions cover virtually all welding application needs. Each mixture was designed to be reliable and simple, yet high performing.
