We covered some important points in the first part of this two part series. We delve a little deeper into what you should look for when buying a plasma machine in this second part of the series.
Testing the Plasma Cutting Machine and Examining Cut Quality
It is a good idea to make cuts on various machines that cut similar thickness of metal at similar speeds in order to determine which machine gives the best cut quality. Also, you must check for dross at the bottom of the plate and also check if the gap caused by the cut or the kerf is angular or perpendicular. Consider a plasma cutting machine that has a focused and tight arc that focuses more power onto the workpiece.
While cutting, check how far away the torch can be moved from the workpiece and still preserve the arc, by lifting up the torch from the metal plate. If the arc is long, it means more voltage and greater the ability of the arc to cut through a plate of more thickness.
Evaluating the Portability of the Plasma Cutter
You may be using your plasma cutting machine for several applications and there may be a need to shift the plasma cutter around the worksite or from one site to another. A portable, lightweight unit will help you transport your plasma cutter around quite easily.
You should also ensure that your plasma cutting machine has adequate storage space for the torch, work cable and consumables. This improves the portability of the machine and you can make sure that the parts are not dragged along and damaged or are lost when being transported.
Determining the Endurance of the Cutting Machine
You will need a plasma cutter that is durable and has well-protected controls. Torch connections and fittings that are safeguarded will have a longer life. Some machines have a protective cover for the various important elements of the cutting machine as well as for the air filter. Air filters play a very crucial role as they make sure that the water and oil are eliminated from the dense air that reduces the machine’s cutting performance.
Ensuring the Ease of Operation of the Plasma Cutting Machine
You must consider buying a plasma cutting system with a control panel which can be read easily and is also user friendly. Anyone familiar with a cutting machine should have the ability to use it without any effort. Clearly printed procedural instructions on the machine unit will aid in setting up the system easily and also in troubleshooting.
Also, check how the plasma torch feels when you handle it. It is best to have a cutting machine that feels comfortable and has a good functional design.
Testing Transfer Characteristics
You must choose a plasma cutter that provides a quick and positive transfer from pilot to cutting at a large transfer height. These machines support gouging better. A good way to check transfer characteristics is by cutting expanded metal or gratings.
While making a decision on which plasma cutter is best for your business, you must evaluate the various factors that will allow you to leverage your plasma cutting table to the fullest and optimize its usage. We’ve covered various factors that you should take into consideration in this two part series which should hopefully make your buying decision an easier one.
