As an official distributor of Hobbyweld gas cylinders, Weld-Tec are able to provide a complete selection of gas cylinders to meet your needs. Simply pay a one off deposit for your first cylinder and first gas fill, keep it for as long as you need and then refill it as often or as little as you like.
Many of our customers do not weld every week of the year and understandably do not want to rent a high pressure gas cylinder they only use occasionally. Alternatives, such as disposable cartridges, are very expensive in relation to a refillable cylinder.
The simple solution is a rental free Hobbyweld cylinder.

Hobbyweld 5 Original/Ultra Welding Gas
A popular shielding gas, ideally suited for MIG welding, in particular sheet metal and thin sections of mild steel under 7mm in thickness, such as car bodywork and light sheet work. Hobbyweld 5 is a unique blend of Argon, Carbon Dioxide and Oxygen gas mix (often referred to as a tri-mix or an argon shield); it is very easy to use and provides a sound weld at very little cost. This gas mix offers a great number of benefits over using straight carbon dioxide for welding; it decreases the chances of porosity, welding spatter and oxidation.
Hobbyweld 15 Original/Ultra Welding Gas
A specially formulat
ed Argon, Carbon Dioxide and Oxygen gas mix (often referred to as a tri-mix or argon shield) which can be used in a number of welding positions. The name comes from the 15% carbon dioxide content; the extra CO2 gives this gas the capability of MIG welding carbon steels up to 18mm in thickness. Welders will experience good arc stability and a broad heat which is due in part to the 2% oxygen content. The combined benefits of good welding performance and minimal spatter make it very popular among the agricultural, on-site and mobile welding market. The wide operating range makes Hobbyweld 15 the best choice for structural steel work, medium gauge plate and general fabrication.
Hobbyweld Argon/Ultra
Generally used when TIG welding stainless steel, carbon steel and aluminium it can also be used on a MIG welder for aluminium and alloys in conjunction with the correct MIG wire. Argon is typically suitable for most TIG welding applications providing a capability of welding at any depth. The repair of alloy wheels, farming equipment, vehicle body panels, model work and metals used for aircraft are among many of Argons popular uses. The Hobbyweld argon cylinder is filled with high purity, high quality gas, enabling us to boast a minimum purity of 99.995%, giving you the best possible results.
Hobbyweld Oxygen/Ultra
This gas is commonly and traditionally used with a fuel gas (propane, acetylene or propylene) for cutting, welding, brazing and soldering. Oxygen supports the combustion of these gases and enables a much higher flame temperature to be achieved in comparison with air. Our 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 our Hobbyweld acetylene cylinder for the perfect portable rent free gas welding kit.
Hobbyweld Acetylene
The number one choice for general welding, cutting and repair applications. Acetylene is the hottest and most efficient fuel gas on the market, making it the preferred product for many applications. It is also the only fuel gas hot enough to weld steel, when using our oxygen and acetylene together, flame temperatures can reach an amazing 3500°C (6330°F). You will typically use between 2 to 3 times the amount of oxygen as you would acetylene so don’t let the smaller size of the cylinder put you off. Using a number 5 welding nozzle with this gas canister will typically provide over 5 ½ hours of welding time.
Hobbyweld Cylinder Ranges
Hobbyweld supply a range of cylinders including;
Hobbyweld Ultra – 20 litre cylinders pressurised to 300 bar (Hobbyweld Ultra), which are ideal for trade users and workshops that are looking to reduce the cost of rental. If you are comparing prices to other rent free options then please remember that the Argon and Hobbyweld mixes from Hobbyweld are 300bar refills rather than 200bar. These cylinders are big enough to last and convenient to move thanks to the integrated regulator and knob.
Hobbyweld Original – 9 litre cylinders pressurised to 137 bar (Hobbyweld Original), which is the ideal replacement for the mobile welder where space and portability are critical. They would also be idea for the home DIY’er who has a car restoration project and doesn’t want to pay through the nose for disposable cylinders. Hobbyweld Original cylinders contain around 27 cylinders worth of disposables making it miles cheaper to use Hobbyweld.
Hobbyweld Acetylene – these cylinders are filled to 800 litres
