GAS

Argon 25

Argon 25 is an argon/helium based mixtures and are inert, non-toxic, colourless and odourless. Supplied in high pressure metal cylinders. Argon 25 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.  

Typical Uses

  • MIG and TIG welding of Aluminium

Description

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.

 

Physical Characteristics

  • Appearance / Odour: Colourless and Odourless
  • Relative density (Air = 1): 1.3
  • Molecular weight: 30.2
  • Density of gas @ 15°C, 325kPa: 1.28Kg/m³

 

Main hazards

  • Only used approved pressure rated equipment.
  • Asphyxiant in high concentrations.
  • Compressed high pressure gas in cylinders.

 

Typical Uses

  • MIG and TIG welding of Aluminium
 

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.

 

  • Keep cylinders and packs in a cool area away from all sources of heat.
  • Close all valves when not in use.
  • Ensure all regulators and other devices attached to the cylinder outlets are free from oil and grease, and able to withstand contents pressures. Check for leaks regularly.
  • Do not store cylinders in an area where in an area where any leaking gas could accumulate.
  • If valve is damaged, do not attempt to operate.
  • If valve does not operate by hand, return the cylinder to the supplier (attach a “faulty” tag).

 

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.

 

 

In case of leaks

  • If cylinder or pack is suspected of leaking, evacuate personnel from the direction in which the gas is likely to flow. Stop leak if possible.
  • Major leaks should only be approached with breathing apparatus.
  • If possible and if safe to do so, remove leaking cylinder or pack to a safe area outdoors and allow contents to empty into atmosphere.
  • Return empty cylinders and pack to supplier with a note to confirm the leak occurred
  • Notify emergency services if required
