Hobbyweld Oxygen


For oxy / fuel cutting and welding. No bottle rental.

SKU: HWO Categories: , ,



Hobbyweld Industrial gases are 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.


  • Colourless and odourless
  • Does not burn but supports and accelerates combustion
  • Non-toxic at atmospheric pressure


  • Vigourously supports combustion
  • Introducing oxygen to conventional air-fuel flames increases the temperature of the flame
Applications and Uses
  • The use of oxygen gives higher flame temperatures than if air is used
  • Use with propane or acetylene for soldering, cutting or welding

Material compatibility

  • Oxygen vigourously supports combustion of many materials, which will not normally burn in air
  • Most lubricants are not compatible with oxygen; oil and grease can ignite spontaneously burning with explosive violence and should not be used with oxygen
  • Oxygen must never be used with Polytetraflourethylene (PTFE) tape, as it will cause combustion
