Hobbyweld 5

(93% Argon, 5% Carbon Dioxide, 2% Oxygen)

As the most popular MIG welding gas mix, there are an abundance of benefits Hobbyweld 5 can provide.

This gas is simple to use and produces a stable arc which results in less spatter and clean up time for the end user, this makes it much more forgiving to the less gifted welder.

Hobbyweld 5 provides good penetration and fusion, making this gas is an optimum choice for MIG welding. This gas is popular with vehicle restoration enthusiasts and provides the best weld quality for bodywork.

This product is recommended for use with sheet or thin sections of mild steel at a thickness of less than 7mm. For thicker steel, please look at Hobbyweld 15.

Hobbyweld 15

(83% Argon, 15% Carbon Dioxide, 2% Oxygen)

As Hobbyweld 15 has been given the name ‘universal’ gas by customers, this shows that the gas can be used for many applications.

This gas mix contains a higher CO2 content than the Hobbyweld 5 so offers combined benefits of good welding performance and minimal spatter make it very popular among the agricultural, on-site and mobile welding market. This gas is used in structural steel work and general fabrication.

Hobbyweld 15 is recommended for use with mild steel at a thickness of over 7mm. For thinner materials, please look at Hobbyweld 5.

Argon

Argon is 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. For more suitable MIG gases, see our range here.

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 model aircraft are among many of Argon’s popular uses; however, it is also used in many applications that you wouldn’t expect, such as filling the gap between your double glazing and the space in a light bulb.

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.

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.

Nitrogen

Nitrogen is a popular purging gas bought by refrigeration engineers and vehicle air conditioning firms.

Just like carbon dioxide, nitrogen has a number of uses. Nitrogen is used frequently to provide balloon drops as an alternative to compressed air as well as the to replace the air inside of a lightbulb.

It has gained popularity in recent years from amateur racing clubs for inflating tyres and is often supplied when you’re getting your tyres changed on your car. Our rent free gas cylinder is compact, lightweight and is perfect for on-site work.

Helium

Helium is a gas lighter than air, with more applications than you might think.

This helium bottle is the same size and is filled to the same pressure as our welding cylinders providing the capability to fill a massive number of balloons, making it perfect for weddings, birthdays, festive parties and much more.

The capacity of this gas cylinder makes it a great alternative to disposable party pack bottles and much cheaper for larger parties too.

There are a number of fittings which can be used with our helium cylinder, ones specifically for latex balloons, and some which fill foil balloons and larger professional tools with hoses and guns which cater for both types.

If you have a large event coming up soon, you will not be disappointed with the value of this gas cylinder

Carbon Dioxide

Carbon dioxide is suitable for a wide range of applications.

This high quality industrial grade Carbon Dioxide cylinder can be used for a wide range of applications, from hydroponics and aquatic gardening to MIG welding mild steel.

Though CO2 can be used for MIG welding, It’s only really suited to the more experienced welder, as users will notice a less stable arc and an increase in spatter resulting in added clean up/finishing time.

For a really good MIG welding alternative, we recommend the Hobbyweld 5 and Hobbyweld 15 products, which are far more forgiving to a beginner welder.

Quick Action Couplings

Quick action couplings are designed for use with the Ultra range and 3/8″ hose fitting. If you are currently working with a welder that uses disposable cartridges, you may also need to purchase a MIG adaptor.

Flashback Arrestors

A flashback arrestor is a safety device featuring a non return valve which is used to prevent flashback into the gas cylinder. Flashback Arrestors must be used in accordance to The Acetylene Safety (England and Wales and Scotland) Regulations 2014.

We supply flashback arrestors for both our Oxygen and Acetylene cylinders.

The gas bottles from HobbyWeld have made my welding projects so much smoother and safer.
