Claim 17:
18. An attachment for a plasma arc torch, comprising:
an outer retaining cap that is attachable to the plasma arc torch and that is configured to secure a shield cap to the plasma arc torch;
a sleeve located radially outward from the outer retaining cap and configured to receive a flow of pressurized gas;
an insulator located between the outer retaining cap and the sleeve;
a gas flow channel configured to direct a gas flow from the sleeve to a distal portion of the outer retaining cap; and
a shield extending from the sleeve axially past a distal terminal end of the outer retaining cap, wherein the shield is radially offset from the outer retaining cap so as to form an air gap between the shield and the outer retaining cap for conducting the gas flow to a distal terminal end of the plasma arc torch.
