Is an argon/helium based mixtures and are inert, non-toxic, colourless and odourless. Supplied in high pressure metal cylinders.
Used in GMAW and GTAW for aluminium and aluminium alloys (Argon 25 up to 6mm).
Is faster than argon, producing flatter, smoother, broader weld beads with greater penetration, fewer defects and improved productivity. It does not produce as fierce an arc as Argon 75 and gives less chance of burn through in thin sections.
Cylinder dimensions are approximate – variations may occur due to manufacturing tolerances
Height includes the valve
Storage and handling
Ensure adequate ventilation for all cylinders and packs. Secure single cylinders in upright position and protect valves and manifolds from accidental damage.
N.B. Only regulators, manifolds and ancillary equipment, rated for the appropriate pressure and compatible with the relevant gas, shall be connected to or downstream of these cylinders.
