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.

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

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.

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

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
