Whether you’re looking for the best cheap plasma cutter, the best 120V plasma cutter, the best 50 amp plasma cutter or anything else, we’ve got you covered. 

Before we take a look at the best plasma cutters, however, here’s a quick rundown of what exactly plasma cutters are and how they work.  

What are Plasma Cutters? 

Plasma cutters are machines that use ionized gas torches to cut through conductive materials such as metals. They are mostly used to cut steel, stainless steel, copper, aluminum and brass, although they can be used on a wide range of other materials. 

Plasma cutting first emerged in the 1960s when it proved to be a more effective way of cutting metals than plasma welding. It is safer, more accurate and less messy than traditional metal-on-metal cutting. It also produces cleaner edges than oxyfuel cutting, a technique that uses a combination of fuel gasses and oxygen. 

While early plasma cutters were large and slow, technological advances have made many small, lightweight machines available, opening plasma cutting up to hobbyists. Plasma cutting is also commonly used in large-scale CNC applications and across industries such as automotive repair, construction and in fabrication.

Using a plasma cutter is relatively simple and beginners can get to grips with it fairly quickly. Once you’ve set up your cutter and connected it to an air compressor and a power supply, you just need to attach the torch to the cutter, select your cutting amperage and get to work. Some of the best plasma cutters even have built in air compressors to make the process simpler.
