Industrial gas cylinder ARCAL™ Chrome

gasCO2cylindrical

DESCRIPTION
ARCAL™ Chrome, argon 2% CO₂ cylinder for welding: a shielding gas formulated for MAG welding of stainless steels. The mixture of argon with 2% CO₂ is designed to preserve corrosion resistance of stainless steels and to produce an attractive weld bead appearance. ARCAL™ Chrome has low levels of water and nitrogen impurities to reduce welding defects and minimise finishing operations. Suitable for manual, semi-automatic, automatic or robotic welding.

Applications

• Welding stainless steels in all positions and for general applications
• MAG brazing with CuSi and CuAl filler wires

Benefits provided by ARCAL™ Chrome

• Simplicity : optimal choice for MAG welding of stainless steels.
• Quality : preserves corrosion resistance properties of stainless steels (austenitic and ferritic).
• Performance : reduces finishing work thanks to very low spatter levels, improving productivity.

Carbon footprint reduction
ARCAL™ Chrome is produced and packaged in cylinders and frames in France using 100% renewable electricity (low-carbon production and packaging declared for certain sites).

Supply modes
Available in cylinders of various capacities and in frames (bundles of several cylinders) according to consumption volumes.

SMARTOP™
ARCAL™ Chrome argon 2% CO₂ cylinders can be fitted with the SMARTOP™ head: facilitates regulator connection, features an on/off lever and a pressure gauge for simplified handling and improved safety.

EXELTOP™
Optionally, cylinders can be equipped with an EXELTOP™ head integrating a regulator (double stage) for precise and stable flow, on/off lever and Quick Connect fitting for ready-to-use operation.

SAFETY & TRANSPORT
Hazards: contains gas under pressure; may explode if heated. Asphyxiant at high concentrations. Flammability range: non-flammable.
