Hobbyweld 5 Argon / CO2 MIG mix
Hobbyweld 5 Argon / CO2 MIG mix
£ 42.00
A low cost MIG welding gas for sheet steel welding. No bottle rental (9 litre)
Sorry this item is out of stock


A solution for hobby or occasional users for whom bottle rental charges from other gas bottle suppliers are uneconomical.  A refundable deposit is payable on initial rental, and thereafter only the cost of the gas is payable on exchange for a full bottle.  For obvious reasons, these bottles are for collection or local delivery only.

These 9L bottles are equivalent to 21 x 600ml disposable cylinders or 13 x 1L disposable cylinders, and use the same regulator fittings as BOC, Air Products and Air Liquide.

The average welding time for a CO2/Argon mix cylinder is 5 hours continuous welding 


  • Good penetration and fusion profiles
  • Excellent arc stability
  • Low distortion
  • Low oxidation potential
  • Low levels of nitrogen and moisture


  • Easy to use, providing a sound weld at minimum cost
  • Low oxidation potential
  • Can also be used for MIG welding stainless steel in less critical applications
  • High strength welds
  • Minimal splatter producing good appearance and finish
  • Minimises post-weld treatment and rework
  • Low porosity and other defects

Applications and uses

  • Specially formulated for MIG welding sheet and mild steel less than 4mm thick
  • A suitable gas for use in vehicle repair as it provides dip transfer in all positions with solid wire
  • The oxidising potential of this mixture has a tendency to produce welds with a black surface film, so generally not recommended for stainless steel applications.

Cylinder Gas Pressure - 137 bar (circa 2000psi) at 15°C
Gas Capacity - 1.34m3 average (9 litre water capacity)

Height - 840mm
Diameter - 140mm
*Cylinder weights and dimensions may vary slightly - contents remain balanced*
