The Hobbyweld Original range of gas cylinders were our first line of products, launched back in 2011, to cater for the low volume user.
The Original range includes a 9 litre HP (high pressure) cylinder and a 5 litre DA (dissolved acetylene) derivative.
Due to their lightweight, compact size, they are the preferred choice for those who only weld occasionally, or for someone needing true portability. The 9 litre HP cylinder stands at 840mm high and weighs under 20kg. The 5 litre DA cylinder is 550mm high with a weight below 15kg.
Please note: the cylinder tare weight may vary slightly due to the manufacturing process.
Both the 9 litre and 5 litre Original cylinders weigh no more than the luggage you take on a sunny holiday, making them the product of choice when portability is paramount.
Our 9 litre HP cylinders are filled to a pressure of 137 bar (1987 psi), to put that into perspective, a typical car tyre is only filled to around 33 psi.
For the MIG welders, a 9 litre Hobbyweld 5 cylinder would provide around 100 minutes(1) of continuous use. The welding time is typically higher for TIG welding applications.
Carbon Dioxide under pressure takes the form of a liquid, which is measurable by weight. Both our industrial CO2 and food grade CO2 cylinders are filled with 6kg of product, the same quantity of gas that a typical pub would use in their cellar.
Finally, our 5 litre (portapack) DA cylinders are filled with 882g of acetylene dissolved in acetone, giving around 370 minutes(2) of continuous welding.
If you’re currently using disposable MIG welding cartridges, the Hobbyweld Original range is the perfect alternative. Not only are our cylinders better for the environment and built to last, you’ll benefit from infrequent visits to the local hardware store, whilst saving a tonne of money too.
One 9 litre shielding gas cylinder is comparable to 23 disposable gas cartridges. With typical prices ranging from £12 to £14 per cartridge, you’d be shelling out at least £276 for the same amount of gas as just one of our cylinders. It’s easy to see why we are often the first port of call when upgrading a welding setup.
Hobbyweld Original cylinders are fitted with industry standard valves – the same valves you would typically find on larger industrial gas cylinders, such as our medium sized Plus range.

Many welding machines are supplied with certified regulators which fit our cylinder perfectly, so no need to hunt around for adaptors. If you have been using disposable cartridges, and upgrading to a Hobbyweld cylinder, a gas conversion hose may be required to get you up and running – your local Hobbyweld agent can supply these.
