If you’re looking for a plasma cutter, you probably know at least what it is and what is does. But if not, we’ll give you a quick lesson.
Plasma cutters are a specific form of cutting technology that employ a high-speed jet of an ionized gas to control the course of an electric current from the machine to the material to be cut. The plasma cutter heats the cutting material to a temperature hot enough to be begin to melt it, while the ionized gas stream forces the molten metal away to achieve the disjunction.
Plasma cutters are extremely fast when cutting thinner pieces of metal and are well worth the money. Their cost is quickly going down as plasma cutters are shrinking in size and as they become more ubiquitous. The new portable systems are packed with more advanced technological features, while becoming easier to use, even for beginners.
When purchasing a plasma cutter, there are several things you should look for. Prospective purchasers should test out any machine before they buy it. Ask to make some test cuts on several different machines before settling on one. A good rubric to use is cut speed. Choose materials of approximately the same thickness and measure the time it takes to complete each cut with the various machines.
Also, check to make sure to examine the underside of the material looking for excess dross buildup. This would indicate that the machine is not cutting with enough power. Look for a cutter with a concentrated and focused cutting area on the cutting metal.
If you plan to use your plasma cutter in different locations, you will want to look for a portable model. The machine should be light enough for you to carry or should include wheels for transporting. Depending on how much space you have in your garage or workspace, you may want to choose a smaller machine over one of the larger models available.
Since you will probably using your new welder quite frequently, it’s important that it is comfortable for you to use and is easy for you to operate. Look for something with a simple LED control panel that you can operate without a lot of thought. It should also include specific safety functions such as an automatic shut off and appropriate warning sensors.
Finally, make sure you choose a rugged and durable model. The unit will take a lot of abuse over the years and needs to be able to stand up to the elements. A solid chassis is needed to keep the internal parts safe.
As you can see, deciding which plasma cutter to purchase is quite the undertaking and a process that should not be taken lightly. There are many important aspects to consider before making your final buying decision. But, if you take the appropriate measures and foresight, you will end up with a machine that will last for many years and provide you with a positive cutting experience.
