Top Picks for Portable Plasma Cutters 2021 may earn a commission if you purchase a product through one of the links provided.

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.

Q: Is drag technology better than non-touch technology?

A: Yes, drag technology lets you cut materials up to 1/8-inch, whereas non-touch technology only focuses on reducing the higher frequency ground circuit.

Q: As a beginner, is it fine to invest in a cheap plasma cutter?

A: Unlike what most people believe, there is a range of affordable plasma cutters that work as great as any other cutter. Brands like Lotos and Super Deal manufacture a few of the best affordable plasma cutters.

Q: How thick of steel can a plasma cutter cut?

A: Approximately 1 inch
Plasma cutters are used for cutting and gouging operations, with the average hand-held machine capable of cutting up to around 1-inch thick metal. Plasma requires pressurized air and a significant quantity of electrical power.

Q: Can I cut copper with a plasma cutter?

A: Copper is suitable for cutting with a plasma cutter due to its electrical conductivity. You'll need a plasma cutter with a 50 amp output and the exact specifications for plasma cutting steel. Cut slowly at first, and then add a piece of steel on top of the copper to facilitate the operation.

Q: Do you need a welding mask for plasma cutting?

A: Technically, no. When it comes to plasma cutting, many people choose goggles or even darkening safety glasses. However, if the torch you're using has a high enough amp rating, a welding mask is a good idea for safety.


When buying a plasma cutter, there’s more to consider than just versatility and durability. If we were to suggest, the Hypertherm Powermax30 Plasma Cutter is one of the best plasma cutters for its extensive features like the handheld operation, in-built air compressor, and moisture removal technology.
