Hobbyweld Oxygen
Oxygen is commonly and traditionally used with a fuel gas (acetylene, propane or propylene) for cutting, welding, brazing and soldering.
This supports the combustion of these gases and enables a much higher flame temperature to be achieved in comparison with air.
Hobbyweld Oxygen cylinders are filled from a bulk tank which ensures optimum purity, a 1% reduction in purity can increase consumption of oxygen by 20% or more, so you can see the benefits of a professionally filled gas bottle.
Combine this gas bottle with Hobbyweld Acetylene cylinder for the perfect portable rent-free gas welding kit.

How old do I have to be to purchase a gas cylinder?
You need to be at least 18 years old to purchase a Hobbyweld cylinder.
I haven’t got a Hobbyweld cylinder, can you fill my old bottles?
In short, unfortunately not. It is illegal for anyone to fill a cylinder which belongs to another gas company, as Hobbyweld have no record of cylinder tests, age or contents . These must be repatriated with their rightful owner.
Once I pay my deposit, does the cylinder belong to me?
No. Cylinders always belong to Hobbyweld, this also means that they are responsible for the cylinder maintenance. However, there are no time restraints on how long you keep the Hobbyweld cylinder.
Why is the Acetylene deposit more expensive?
Acetylene cylinders cost much more to manufacture. The gas cylinder contains a porous filling and the acetylene is dissolved in an acetone to produce the gas you withdraw.
What administration charges apply to the deposit return?
An administration charge will be applied when returning your cylinder for a refund, of £10 +VAT for all cylinders purchased on or after 1st February 2019.
For cylinders purchased before this date, the following admin charges apply:
Original: £10 +VAT
Plus: £10 +VAT
Ultra: £15 +VAT
Acetylene (all sizes): £30 +VAT
What happens if I lose my copy of the deposit form?
Unfortunately, you will be unable to receive a refund without your original deposit form as proof of purchase. The requirement of deposit forms for refund is an additional security measure to discourage theft of Hobbyweld cylinders in private households. Please keep this safe.

Will my regulator fit a Hobbyweld cylinder?
Hobbyweld Original and Plus cylinders are fitted with standard industrial gas valves used by companies such as BOC, Air Products, Air Liquide & Dixons Gas Ltd. If you have been using an industrial gas cylinder previously, your regulators will fit. If you are currently using disposable cylinders, you will require an adaptor hose and a regulator.
The Hobbyweld Ultra cylinder is fitted with a built-in regulator. Instead, attach your hoses directly a quick action coupling, these are available to purchase from TCC services.
Lastly, if you are using Oxygen and Acetylene we strongly advise using a flash back arrestor as well as a regulator to connect to Hobbybrew cylinders.
Can I exchange between gas mixes?
Yes. Providing the cylinder deposit value is the same, you can swap between gas mixes.
How many disposable cartridges are your cylinders equivalent to?
The Hobbyweld Original cylinder is equivalent to approximately 21 disposable gas cartridges.
Hobbyweld Plus cylinder is equivalent to approximately 79 disposable gas cartridges.
The Hobbyweld Ultra cylinder is equivalent to approximately 100 disposable gas cartridges.
Do cylinders have an expiry date?
Gas cylinders require a test usually every 10 years, a ‘test ring’ is located around the cylinder valve which indicates when it should next be tested. Cylinders are safe to use after the date has passed, however they won’t be refilled after being returned to Hobbyweld until they have been retested. Hobbyweld are responsible for the re-testing of their gas cylinders and you won’t have to pay a penny.
How do I return an unwanted cylinder?
You can return your cylinder to any Hobbyweld agent for a refund on your deposit. You must have your original deposit form to reclaim any money. Alternatively, agents can accept cylinders back without a deposit form, but no money will be returned to yourself.
