Rent free Acetylene - Hobbyweld Ultra Cylinder
Slightly different to the mixed gases this acetylene gas cylinder is smaller in height but larger in diameter - 220mm. Contents wise, we often get asked "is it real acetylene?" to which the answer is very simply yes it is pure "dissolved acetylene" as available from the major gas suppliers, only rent free.
Some other gas suppliers try to push "Propylene" because they don't have acetylene and these companies market Propylene as an alternative to acetylene when it is in fact just 60 degrees hotter than oxy / propane and it is still a very oxidising flame leaving you with the only option of using acetylene to be able to fusion weld.
In each cylinder you get just under 2.5 cubic meters of acetylene. This is enough contents to give a maximum withdrawal rate of 486 litres per hour.
