Plasma cutting came to light in the 1960s, out of plasma welding, and commenced as an effective process to slit metal sheets and plates in the 1980s.
It had the edge over the conventional “metal against metal” cutting of producing no metal chips, giving perfect cuts, and producing a cleaner edge than Oxy-fuel cutting.
What is a Plasma Cutter?
Plasma Cutter slits down the metal by directing air or inert gas through the plasma torch, sparking an electric arc, and then forcing plasma through the torch tip to slit the metal.
The plasma cutter curve can reach up to the temperature of 45000 degrees F, which turns it into one of the fastest ways to slice the metal.
Plasma cutters come up with an on/off switch and amperage settings that regulate the power to use for cutting.
Provided with so much power yet plasma cutting is a safe, and clean way to cut metal.
Process of Plasma Cutting
Plasma Cutting, also known as plasma fusion cutting, is a process that employs superheated, ionized gas channeled through the plasma torch to heat, melt, and ultimately slit the material into shapes and designs.
Plasma cutting is a constructive way of cutting for a wide range of materials like structural steel, copper, and aluminum, and thickness ranging between 0.5mm to 180mm.
Plasma cutting is often presented as a substitute for laser cutting and water-cutting and has certain advantages over these options, like faster cutting and low operational cost.
Plasma Cutter Parts
In a nutshell, the plasma cutter parts are components of the plasma cutter. Most of the plasma cutters consist of a swirl ring, electrode, nozzle, shield cap, and retaining cap.
These components remain the same for the cutting torch, including Hypertherm powermax 65 fine cut consumables and Hypertherm plasma cutter parts.
1. Swirl Ring
It is a small component inside the torch that revolves the gas surrounding the plasma arc. Basically, it is a protective layer that protects the Nozzle from burning.
An electrode is a slim piece of paper containing hafnium. Its main task is to carry electric current from the torch to the plate where it is connected and to focus the charge through the tip, which causes it to work on the workpiece.
The Nozzle focuses the arc and the gas surrounding the material to make a slice clearly. The bigger nozzles are good for gouging, while the nozzles with small openings are better for the fine detailed work.
4. Shield Cap
This cap's role is to protect the torch and other components from sparks during the plasma cutting process.
5. Retaining Cap
The role of the retaining cap is to hold all the consumable parts of the torch together. As this component holds the consumables together, it degrades over time.
Tips to prolong the plasma cutter consumables
Cutting Parameters: Slicing quickly, slowly, and at the wrong distance from your material can wear your consumables more quickly.
Right Installation: Installing your parts is essential for the perfect functioning of the plasma cutter. Make sure the consumables can tolerate the amperage and are well assembled.
Observing: Keep track of your components and how they are wearing so that you can replace the worn part with the new one. This keeps other parts unaffected. Also, make sure to change the Nozzle and electrode frequently, or they will strain the whole system.
The above tips apply to all the plasma cutter parts, including Hypertherm plasma cutter parts.
Benefits of Plasma Cutting
Plasma cutting has many benefits that have made it an attractive application in many industries. Let’s have a look at them:
Enhances the speed of cutting.
One can work on a wide range of materials.
It offers portability to work on job sites.
There is no requirement for the preheat cycle.
As with any other machinery, it is essential to check out the plasma cutter and to make sure the plasma cutter you buy has a good return policy in case it does not work for you.
In addition, you should also keep the above tips in mind to maintain your plasma cutter and plasma cutter consumables.
