Plasma cuts through electrically conductive materials like a hot knife on butter. Plasma cutters are by far the most versatile metalworking tool which delivers flawless professional cutting, in a matter of minutes.

Speed, precision, and efficiency are a few of the reasons we prefer plasma cutters over oxy-fuel torches. The air pressure in plasma cutters is constricted and outperforms any other method even when cutting stacks of metal at once. But, it may be quite daunting when picking one that meets your needs.

Narrow down your search by asking yourself questions like how often you would use it, what material you would like to cut, if you want it to be portable, how you will power the plasma cutter (generator/adapt power), etc.

To save you the effort, we have listed five of the best products so that you can pick the best portable plasma cutter for yourself.
