Hobbyweld 15 is a specific blend of 83% Argon, 15% Carbon Dioxide and 2% Oxygen, Great for MIG welding of steel between 5mm and 12mm thick,

This trimix shielding gas is great for heavier gauges of steel and is often used in engineering facilities for general metal fabrication. The increased percentage of carbon dioxide in this mixture allows you to weld up to 18mm in steel thickness.83% Argon / 15% Carbon Dioxide / 2% Oxygen

Hobbyweld 5 original is a mixture of 93% Argon, 5% Carbon Dioxide and 2% Oxygen, Ideal for MIG welding of steel less than 5mm thick eg car panels.

The Hobbyweld 5 Ultra cylinder is perfect for welding mild steel under 7mm, combined with the increased gas capacity of the Ultra cylinder makes it ideal for much larger projects.93% Argon / 5% Carbon Dioxide / 2% Oxygen

Hobbyweld Stainless 98/2 is a blend of 98% argon and 2% carbon dioxide, this provides an entry level gas for those welding stainless steel below 8mm. 98/2 provides greater fusion and welding characteristics than if pure argon is used. This gas is suitable for MIG welding stainless steel.

Acetylene is perfect for general welding, cutting and repair applications. It is the hottest and most efficient fuel gas on the market,

Hobbyweld AL50 gas is designed for customers welding thicker sections of aluminium and requiring higher strength welds than what pure argon can provide. The customer will also experience a higher level of spatter and porosity control as well as greater weld speeds (by up to 50%). The Hobbyweld AL50 aluminium mix is a blend of 50% helium and 50% argon and is also suitable for welding other non-ferrous metals such as copper and titanium alloys.50% Argon / 50% Helium

If you own a TIG welder and you're looking to weld a wide range of materials - high purity argon is a great place to start (combined with the correct consumables, you can also use argon on a MIG welder). 99.995% Argon

Ideal for dispensing drinks. Not for welding purposes.

Carbon Dioxide is suitable for a wide variety of welding applications and will weld a large range of thicknesses. Carbon dioxide is a cheap alternative to Argon mixes but also produces a large amount of spatter, leaving you with an untidy weld in comparison to Argon

Our helium cylinder is filled to the same pressure and is the same size as our professional welding cylinders. It has the capability to fill over 160 balloons

Nitrogen is a popular purging gas and is bought by refrigeration engineers and vehicle air conditioning firms. Nitrogen is also used frequently to provide balloon drops as an alternative to compressed air. It has recently received increased popularity from go-karting and amateur racing clubs for use in filling tyres.

The Ultra oxygen cylinder is perfect for the professional user, it's huge capacity and contents gauge means you're much less likely to run out over that busy weekend. Combined with a fuel gas - there are so many applications you can perform - cutting steel, soldering brass, welding steel.99.5% Oxygen

Argon is an inert shielding gas which is suitable for most TIG welding applications. It is most commonly used when welding aluminium and stainless steels in thin section.

Industrial grade oxygen is commonly used with a fuel gas for cutting, welding, brazing and soldering as it supports combustion and gives much higher flame temperatures than if air is used. For cutting with oxygen an oxy-fuel flame preheats the steel to its ignition temperature further to which gaseous oxygen flows onto the red-hot steel, generating more heat and melting the steel.

R134a refrigerant gas is now available for recharging vehicle air conditioning in the automotive aftercare market

The Hobbyweld SS50 is a blend of 50% helium, 48% argon and 2% carbon dioxide. This gas is specifically manufactured for those welding stainless steel with a thickness in the range of 3 to 10mm and offers the best overall weld speed, spatter control, fusion and weld penetration. This gas is the industry standard for professional stainless steel welding applications

The trace gas mix comprises of 5% hydrogen and 95% nitrogen (oxygen free) to make a non-flammable, non-toxic gas which, when used with specialist hydrogen detection equipment can search for minute leaks. This process is up to 100 times more sensitive than common leak detection methods.
