Plasma cutters have become a popular tool in the metal industry, as they offer many benefits that traditional cutting methods cannot match. Not only can they cut through a wider range of materials, but they also provide a smoother and more accurate cut, making them an essential tool for metalworkers who demand precision and efficiency.
So how does a plasma cutter work?
A plasma cutter uses high-frequency electrical arcs to ionize and heat up gas, usually compressed air, into a superheated plasma stream. As this stream travels through the nozzle of the torch, it cuts through the metal by melting it and blowing away the molten material. The plasma stream can reach temperatures of up to 30,000°F, making it powerful enough to cut through almost any material.
When choosing a plasma cutter, there are several factors to consider based on your specific needs. Here are some of the best models in three different categories: portable, metal art, and industrial.
Best Portable Plasma Cutter for DIY
For DIY enthusiasts or small metalworking shops, a portable plasma cutter may be the perfect option. The Hypertherm Powermax45 XP is a user-friendly tool that cuts up to 5/8-inch thick material and is lightweight enough to be carried from job to job. It also has a variety of torch options, including a hand torch and a mechanized torch for CNC cutting machines.
Best Plasma Cutter for Metal Art
Metal artists require a more specialized plasma cutter that can cut intricate shapes and designs with precision. The Hobart Airforce 27i is an ideal option for this purpose, as it has a lightweight design, and its multi-voltage plug makes it easy to use in any location. The machine also has a built-in compressor, so there is no need for an external air supply.
Best Industrial Plasma Cutter
For high-volume production or heavy-duty tasks, an industrial plasma cutter is needed. The Hypertherm Powermax105 is a reliable option capable of cutting materials up to 1-1/4 inch thick. This heavy-duty cutter has advanced features such as automatic gas regulation, automatic electrode cleaning, and a CNC interface, making it one of the most versatile and efficient plasma cutters on the market.
In conclusion, a plasma cutter is a valuable tool for any metalworking shop, as it offers many advantages over other cutting methods. When choosing a plasma cutter, consider the materials you will be cutting, the level of precision required, and the amount of production. By selecting the right plasma cutter for your needs, you can ensure that your metalwork is of the highest quality and precision.
