Claim 2:
3. A plasma arc torch, comprising:
a nozzle body;
a nozzle extending from the nozzle body;
a shield cap;
an outer retaining cap attached to the plasma arc torch that secures the 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; and
a shield extending from the sleeve axially past a distal terminal end of the outer retaining cap, wherein at least one of the sleeve and the insulator forms a gas flow channel configured to direct a gas flow from the sleeve to a distal portion of the outer retaining cap, and wherein the shield is radially offset from the outer retaining cap and the shield cap so as to form an air gap between the shield and both of the outer retaining cap and the shield cap for conducting the gas flow to a distal terminal end of the plasma arc torch.
