What You Need to Know When Seeking the Best Prices on a Plasma Cutter
Plasma cutters, though basically similar to torches and welding equipment, are different because they are designed to cut metal use a plasma beam. The term plasma refers to the fourth state of matter, a high energy state of matter in which a substance is super heated. Perhaps the best example of a plasma is what happens to the hydrogen and helium on the sun which is super heated by the constant fusions reactions into a plasma state. In a plasma, the ionized gas is super heated until it reaches an unbelievably high temperature, and has properties of both a liquid and a gas. To heat an ionized gas into a plasma beam, you have to heat to temperatures approaching 15,000 degrees Celsius.
If a plasma cutter gets that hot, you may be wondering how you can possibly use it safely on the work site. The compressed gas is then ignited by a high voltage spark which quickly heats it to the point that a plasma if formed. For instance, if the specifications of a plasma cutter refer to it being 50 amp or that it is a 3200 dual voltage plasma cutter these are referring to the actual high voltage spark that heats the gas into a plasma.
The nozzle of the plasma cutter is soon flooded with compressed gas where it comes into contact with the high voltage spark and is instantly super heated to temperatures approaching 15,000 degrees Celsius, where it flows out a small opening in the nozzle and is directed onto the material that you are planning to cut. These days there are two basic types of approaches used to making a plasma in a plasma cutter. These two general types of plasma cutters are HF contact, or high frequency contact, plasma cutters and plasma cutters that create plasma through the use of a pilot arc.
There are several advantages that a plasma cutter offers you that you can not get from any other type of metal cutting device. Since the plasma is actually forced through a tiny opening, it is speeded up and focused into a highly concentrated beam. With such a fast and highly concentrated beam of plasma, your plasma cutter can actually make cuts that are accurate as a laser cutter but much faster. Plasma cutters are available in hand held configurations that make them completely portable, or mounted on CNC cutting tables which means that they are the perfect solution for just about any kind of metal cutting application.
Anyone who is interested in finding out more about the best value on a plasma cutter should begin by reading reviews of various plasma cutters online. For more information about plasma cutters, including detailed specks on particular models, details about how plasma cutters work and reviews of the most popular plasma cutter models, all you need to do is search the Internet for plasma cutters in your area.
