Hobbyweld 15 (Original) is a MIG/MAG shielding gas for welding thicker sections of steel. It’s a tri-mix of argon, carbon dioxide and oxygen, roughly 83% argon, 15% CO2 and 2% oxygen, sometimes called an argon shield. The higher CO2 content is what makes it suited to heavier steel, generally from about 7mm up to 15mm or so.
It welds with good arc stability and minimal spatter, which is why it’s a popular choice for general fabrication, repairs and light trade work, as well as agricultural, on-site and mobile welding. This is the Original cylinder: a 9-litre bottle at 137 bar.
A cylinder of this type needs a suitable regulator to set your flow. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
Hobbyweld 15 (Ultra) is the high-capacity version of the 15 mix, a MIG/MAG shielding gas for welding thicker steel. It’s the same argon tri-mix with around 15% CO2 and 2% oxygen, but in a bigger 20-litre cylinder at 300 bar, so you get a lot more welding time between refills.
The CO2 content lets you weld up to around 18mm in steel thickness, which suits heavier-duty work and engineering-type fabrication. It’s easy to use too: the cylinder has a built-in regulator to set your flow rate, and the push-fit system connects in seconds.
This is the Ultra cylinder, the one to choose if you weld a fair amount and want fewer changes. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
Hobbyweld 5 (Original) is a bestselling MIG shielding gas, ideal for thinner sheet steel. It’s an argon tri-mix, roughly 93% argon, 5% CO2 and 2% oxygen, sometimes called an argon shield, and the lower CO2 content makes it well suited to mild steel under about 7mm, such as car bodywork and light sheet work.
Compared with straight CO2, it reduces the chance of porosity, spatter and oxidation, which gives a cleaner, sounder weld at a low cost. That’s why it’s a favourite for vehicle restoration, classic cars and motorcycles. This is the Original cylinder: 9 litres at 137 bar.

Hobbyweld Acetylene (Original) is the fuel gas for general welding, cutting, brazing and repair work. Acetylene is the hottest, most efficient fuel gas there is: paired with oxygen, the flame can reach around 3500°C, which is hot enough to weld steel.
In an oxy-acetylene set you use roughly two to three times as much oxygen as acetylene, so the smaller acetylene cylinder is the sensible size. The Original is a 5-litre cylinder with a gas capacity of around 0.81 cubic metres, which typically gives over five and a half hours of welding time with a number 5 nozzle.
For safety, flash back arrestors must be fitted to oxygen and fuel-gas equipment, in line with the Acetylene Safety Regulations 2014. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
Hobbyweld Acetylene (Ultra) is the high-capacity acetylene cylinder, made for the professional or heavier user. It holds much more gas than the Original, with a water capacity of around 15.9 litres and a gas capacity of about 2.55 cubic metres, and it has a built-in contents gauge so you can keep track of what’s left.
Acetylene is the hottest, most efficient fuel gas on the market, and the only fuel gas hot enough to weld steel. Used with oxygen in an oxy-acetylene set, it handles cutting, welding, brazing and soldering.

The Hobbyweld Argon Original cylinder is pure argon for TIG welding, filled to a minimum purity of 99.995% so you get clean, steady results. It handles stainless steel, carbon steel, aluminium and other non-ferrous metals, which covers a wide spread of real jobs: alloy wheel repairs, farm equipment, vehicle body panels and finer model work. Run it on a MIG welder with the correct wire and consumables and it does aluminium there too.
This is the Original size, 9 litres water capacity filled to 137 bar. It’s a manageable cylinder for hobby and occasional welding, the right pick if you don’t get through a lot of gas. If you weld regularly or want longer between swaps, the Ultra cylinder holds more and has a built-in contents gauge.

The Hobbyweld Argon Ultra cylinder is the big-capacity choice for anyone who welds a fair amount. It’s pure argon filled to a minimum purity of 99.995%, the standard shielding gas for TIG welding stainless steel, carbon steel, aluminium and other non-ferrous metals. On a MIG welder with the correct wire it covers aluminium and alloys too.
The Ultra is 20 litres water capacity, filled to 300 bar, so it holds well over twice the gas of the Original cylinder. It also has a built-in contents gauge, which is the part professionals tend to want: you can see at a glance how much gas is left rather than guessing mid-job.
The bigger capacity means fewer swaps and less interruption when you’re working through argon. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
The Hobbyweld Helium Original cylinder is 100% helium for inflating balloons, and a single bottle fills a large number of them. That makes it a far better value option than the small disposable party-pack bottles, especially for weddings and bigger celebrations where you’d otherwise be buying several throwaway packs.
It works with the valve fittings for latex or foil balloons, and with larger professional hoses and guns that suit both types, so it covers everything from a quick batch of party balloons to a full decorating job.
This is the Original size, 9 litres water capacity filled to 137 bar, a manageable cylinder for home and event use. If you’re filling for a really big event, the Plus cylinder holds considerably more.

The Hobbyweld Helium Plus cylinder is the big-capacity helium bottle, made for events where you’ll get through a lot of balloons. It’s 100% helium and fills a huge number of them, so for a large wedding, a marquee party or a venue decorating job it saves you swapping cylinders part-way through.
It works with the valve fittings for latex or foil balloons, and with the larger professional hoses and guns that handle both, so it suits anyone inflating in volume rather than a handful at a time.
The Plus is 20 litres water capacity, filled to 230 bar, well above the 9-litre Original, so you fill far more balloons before needing another. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
The Hobbyweld Oxygen Original cylinder is 100% oxygen for cutting, welding, brazing and soldering. Used with a fuel gas such as propane, acetylene or propylene, it supports combustion and lets the flame run far hotter than it could on air alone, which is what makes gas cutting and welding possible.
Purity matters here more than people expect. Even a 1% drop in purity can push oxygen consumption up by 20% or more, so Hobbyweld fills these cylinders from a bulk tank to keep purity high and your gas use efficient.
Pair it with a Hobbyweld acetylene cylinder and you’ve got a compact, portable gas welding kit. This is the Original size, 9 litres water capacity at 137 bar. In line with the Acetylene Safety Regulations 2014, flash-back arrestors must be fitted with oxygen and fuel gas equipment. We deliver across our defined Reading area, so check your postcode is covered, or call the yard on 0118 9242888.
The Hobbyweld Oxygen Ultra cylinder is the large-capacity oxygen bottle, built for professionals and anyone who cuts or welds regularly. It’s 100% oxygen, used with a fuel gas such as propane, acetylene or propylene for cutting, welding, brazing and soldering, supporting combustion so the flame runs far hotter than it could on air.
Purity is worth understanding. Even a 1% drop can increase oxygen consumption by 20% or more, so Hobbyweld fills these cylinders from a bulk tank to keep purity high and your gas efficient.
The Ultra holds 20 litres water capacity at 300 bar, well over twice the Original, and has a built-in contents gauge so you can see what’s left.

This Harringtons drinks dispensing cylinder is a 60/40 mix, 60% CO2 to 40% nitrogen, blended for dispensing lagers and for soda machines. It’s a 10-litre bottle, sized for home brewers and low-usage customers rather than a busy commercial cellar, so it’s a practical choice if you dispense at home or keep a small setup running.
The mix is the part that matters: the higher CO2 proportion suits lagers and carbonated drinks, where you want the carbonation kept up as you pour. For ales and stouts, the 70/30 mix is the one to choose instead.
