ROC supplies a full range of cutting gases for
every process, for every material. The following
cutting gases are available from ROC in various
packages:
Fuel gases:
Plasma gases:
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.
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. |
