PLASMA CUTTING CONSUMABLES: WHAT, WHY, AND HOW LONG DO THEY LAST?
Plasma cutters contain a number of consumable parts, which is unsurprising when you consider the very high temperatures involved in producing and focussing an arc of plasma. Keeping on top of the condition of these consumables is very important as it will help to ensure a consistent high-quality cut, and reduce the time involved in processing and refining your finished parts.
WHAT ARE PLASMA CUTTER CONSUMABLES?
Plasma cutter consumables are a set of components in your plasma cutter that gradually wear over time until they need to be replaced: they have a life cycle. The consumables are all found in the cutting torch itself, which is where most of the energy is focussed, and keeping track of wear and tear is a key part of maintaining an efficient machine that cuts well and lasts a long time. Plasma cutting torch consumables include: a swirl ring, electrode, nozzle, retaining cap, and shield cap.
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.
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.
RETAINING CAP
The retaining 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 CAP
The shield is there to protect the torch and its other components from the sparks and molten metal that result from the plasma cutting process. It takes the brunt of the fallout so that wear to other components is minimised as much as possible.
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.
