Electrode:
The electrode is a narrow piece of copper containing hafnium (which is an excellent conductor of electricity). Its job is to receive the electrical current from a cathode block inside the torch to which it is connected, and to focus the charge through its tip, which causes it to arc onto the workpiece.

Nozzle:
The nozzle focuses the plasma arc and the gas that surrounds it to make a clean and precise cut. A nozzle with a larger
opening is used for gouging, while a nozzle with a smaller opening is better able to direct the gas and so is used for fine, detailed work.

Retain cap:
The retain cap essentially holds all of the consumable parts of the torch together. As temperatures at this end of the machine are extremely high, it's not just the parts creating and focussing the arc that are worn down; the component holding them together also degrades over time.

Shield:
The shield is there to protect the torch and its other components from the sparks and molten metal that result from the plasmacutting process. It takes the brunt of the fallout so that wear to other components is minimised as much as possible.

Swirl ring:
The function of the swirl ring is to spin the plasma gas which has two main results; 1, The spinning gas is gyroscopically stabilised a bit like a bullet making the plasma column less tendency to deflect.

Water tube:
Provides coolant to tip of the electrode to prevent overheating and failure. It is extremely important to use the proper sized water tube. An improper water tube can cause premature electrode failure due to overheating and electrical short circuiting.

Outer retaining cap or Shield cap:
Holds all consumables in place and in conjunction with the shield protects them from sparks and molten metal. Shield caps are made from many different materials that are designed to withstand the high temperatures associated with todays mechanized plasma cutting.

How long do plasma cutter consumables last?
Now that we've looked at the role each of these consumable parts play, we'll move on to discuss how long these elements last. The nozzle and the electrode will wear out more quickly than other components, as they are most directly involved with the creation and focussing of the cutting arc. You'll notice nozzle wear primarily in the quality of the cut you are achieving. As the nozzle wears, the hole in the tip gets larger, which makes the plasma arc thicker and produces a wider cut (kerf) in your workpiece. You will be able to see with a simple visual inspection when the hole in the nozzle becomes too large and needs replacing.
