Will my regulator fit your cylinder?
Our Hobbyweld Original cylinders are fitted with standard industrial gas valves used by companies such as BOC, Air Products, Air Liquide & Dixons of Westerhope Ltd. If you have been using an industrial gas cylinder previously, your regulators will fit.
The Hobbyweld Ultra cylinder is fitted with a built in regulator, instead, attach your hoses directly to the quick action coupling provided.
Lastly, if you are currently using disposable cylinders, you will require an adaptor hose (for Original & Ultra cylinders) and a regulator (Original cylinders only).

Why is the acetylene deposit more expensive?
Unfortunately, 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. If we could make it cheaper, we honestly would.
Once I pay for my cylinder, does it belong to me?
No. Cylinders belong to Hobbyweld at all times, this also means that we are responsible for the cylinders maintenance. However, there are no time restraints on how long you keep the Hobbyweld cylinder.
My new cylinder seems lighter than the last, is that normal?
The weight of the container may vary but content remains the same.
In the unlikely event of you purchasing a faulty cylinder, what should you do?
Your sales contract is with the company your purchased your gas fill from, take your cylinder back to the agent as soon as possible. We issue each reported cylinder with a faulty label and reference code to ensure traceability. Once the cylinder has been returned and tested, if found faulty, a credit can be given to the agent, it is then up to that agent to issue a refund to you. Please bear with us as this process can take anywhere from 1 week to 2 months, this is due to the collection times of empty cylinders, if a fault is found it will result in immediate action.
I think my cylinder has been underfilled, what should I do?
Unlike our filling equipment, which have certified gauges which are routinely calibrated, typical gas contents gauges on your regulator are not, even the slightest knocks can effect them - if it reads less than 2/3 of stated pressure, it may be worth returning the cylinder to your local stockist for us to check.
I haven't got a Hobbyweld cylinder, can you fill my old bottles?
Sorry, but it is illegal for anyone to fill a cylinder which belongs to another gas company, as we have no record of cylinder tests, age or contents - these must be repatriated with their rightful owner.
How do I return an unwanted cylinder?
You can return your cylinder to any of our agents for a refund on your deposit. You must have your original deposit form to reclaim any money. An admin charge will be applied when returning your cylinder for a refund of;
£10 +VAT for Original 9 litre cylinders
£15 +VAT for Ultra 20 litre cylinders
£30 +VAT for Original Acetylene cylinders
How do I order my first cylinder?
It's best to deal direct with your local Hobbyweld agent, they're all friendly and happy to help. If you don't have a local stockist, contact us as we may be able to assist.
Do your 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 us until they have been retested.
Do I need to pay another deposit if I need a spare cylinder?
Yes, this will need to be paid for each additional cylinder.
Can I swap my Hobbyweld 15 for a Hobbyweld 5 on the same deposit form?
Yes, providing the cylinder deposit value is the same, you can swap between gas mixes.
Can I order cylinders direct from you?
Yes, it is possible for us to send most gases by mail, however, this is not the most cost effective method for you to get gas. We strongly recommend visiting a local agent.
Note: We can't post oxygen, acetylene or any Ultra gas cylinder.
Are all cylinders the same size?
Physical dimensions may vary slightly but contents remain the same.
Why is my gas pressure lower when it's cold?
Gas expands as temperature increases and vice versa. As the ambient temperature drops, it will result in a lower pressure reading. Hobbyweld cylinder pressure ratings are filled based on 15ºC
Which CO2 cylinder do I use for what?
Use Gas Hydroponics & Plant Growing Industrial Grade CO2 Welding Work* Industrial Grade CO2 Paintball & Air guns Liquid Off-Take CO2 Drinks Dispense Food Grade CO2
*Industrial Carbon Dioxide can be used for welding, however will give mixed results, we strongly recommend a purpose mixed gas such as Hobbyweld 5 or Hobbyweld 15.
What is the difference between Hobbyweld 5 and Carbon Dioxide?
Unlike straight CO2, Hobbyweld 5 is a precise blend of 3 gases designed to produce optimum results when welding thin sections of mild steel.
My gas isn't lasting long, what should I do?
Perform a check on your system for leaks, if a leak cannot be found it may be that you have your flow rate set too high. Make sure you turn the cylinder off by its valve when you are finished using it, as even a small leak can empty your cylinder over time.
Is your nitrogen food grade?
No, although our nitrogen is 99.995% pure and free from oxygen, we cannot guarantee that it is suitable for food preparation or for food grade use.
I'm looking for a gas you don't sell, can you do it?
It is very costly for us to introduce a new gas to our range, however, if we receive a lot of enquiries for a particular gas we would consider introducing it into the range.
How many disposable cartridges are your cylinders equivalent to?
The Hobbyweld Original cylinder is equivalent to approximately 21 disposable gas cartridges.
The Hobbyweld Ultra cylinder is equivalent to approximately 100 disposable gas cartridges.
Do you sell propane?
No. However, there are a number of Hobbyweld stockists who do. If our stockist doesn't sell it, contact Calor gas on 0800 626 626.
Do you sell acetylene?
Yes we do. see acetylene in our product range
Do I have to refill at the same stockist?
No, our system is designed that you can use any agent which is most convenient, this is especially handy if; you're a mobile welder, you move house or we allocate a new agent closer to you.
Can I used industrial grade CO2 on my home brewing equipment?
Although our CO2 gas cylinders are filled from the same bulk source, it is advised to use food grade CO2 for all home brewing. The cylinders are segregated minimalising the chances of cross contamination.
Can I transfer gas from one cylinder to another?
Never! Not only does this affect the gas mix it can result in catastrophic accidents.
Will there be an agent near me soon?
We hope so! We are always on the look out for potential agents who have a business which fits with Hobbyweld. If you know of a company near you who may be interested in stocking our products please feel free to send us their details, or better still, let them know about us.

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. Please keep this safe!
There is an empty sign on my cylinder, does this mean it's empty?
Chances are, no... Sometimes, people will write empty on their cylinder or stick a label to it, we try our best to remove what we can. Don't worry, but please don't do it.
How old do I have to be to purchase a gas cylinder?
You need to be 18 to purchase a Hobbyweld cylinder.
Do I have to reclaim my deposit from the same stockist I bought my first cylinder from?
No, you can use any agent, providing you have your original deposit form. (with the exception of acetylene - where some agents have no applicable insurance to keep the product on site)
Can you provide certificates of purity?
Individual purity certificates can be provided at a cost of £150.00 +VAT, these are supplied with the cylinder, so you will not be able to request a purity certificate for a cylinder you already have.
