Fuel gases – for oxy-fuel cutting

The high flame temperature required for oxy-fuel cutting is obtained by combining oxygen with one of the following fuel gases:

• Acetylene – the premier fuel gas for cutting due to its high flame temperature, high heat distribution and local heating. The only fuel gas that creates a flame hot enough to cut steel.
• Propane – cheaper but lower productivity than acetylene due to the lower flame temperature.
• Hydrogen  – as a fuel gas in oxy-hydrogen cutting, and for aluminium and underwater cutting.

Plasma gases - for plasma cutting

In plasma cutting, the gas combination is often specified by the equipment manufacturer. We supply:

• Argon/Hydrogen mixtures - used with hydrogen content from 5% to 35%. The higher hydrogen mixtures are more suitable for cutting stainless steel and aluminium. Lower hydrogen mixtures can be used to cut carbon and low alloy steel.
• Nitrogen - frequently used in dual gas torches for cutting all metals. Nitrogen is also used as the shielding gas when plasma cutting with argon/hydrogen as the plasma gas.
• Air - dry compressed air is often used, particularly in small manually operated units for sheet metal cutting.
• Oxygen - normally only used as the plasma gas when cutting carbon and low alloy steels where it has many advantages.
• Carbon Dioxide - used for cooling the nozzle when nitrogen is used as the plasma gas.

We also supply:

• Equipment and consumables for cutting – for oxy-fuel and plasma cutting.
• Laser gases  – a full range of lasing and laser assist gases for cutting applications where high penetration, high speed and precision are needed.
• Welding gases - shielding gases for MIG and TIG welding and fuel gases for oxy-fuel welding.
