What is a plasma cutter?
A plasma cutter refers to a process of cutting conductive materials with accelerated jets of thermal plasma. The plasma cutter is used for metal cutting in large-scale operations and is usually combined with a cutting table.

How to choose a plasma cutter?

Plasma cutters are rated according to their amperage. The thicker the material, the greater the current intensity required to cut it.

Cutting Speed

The cutting speed of a plasma cutter means work efficiency. So remember to check the IPM value before you buy it. The larger the IPM value, the higher the work efficiency.

Duty Cycle

Duty cycle refers to the ratio of the length of time that the plasma cutter works and cools in ten minutes. For example, a four-minute duty cycle means that the plasma cutter needs six minutes of cooling for every operation. Generally, a long duty cycle is suitable for deep or long cuts because it takes longer to cool down.


Some parts of the plasma cutter are consumables, such as the cutting head and electrodes, and need to be replaced frequently.
