Sometimes welding metal altogether is not the only you to do, there are times when you want it cut it apart and the best way to do is using a plasma cutter. If you spend time doing metalwork you understand how important it is to have a plasma cutting system to make a smooth clean cut on metal.

The plasma cutting system utilizes compressed air or gases to ionize for creating plasma as they make contact with the electrode. Torch holds the consumable electrodes housed inside the retention cup where plasma is formed. This super-heated plasma with high-velocity arc can directly cut through all types of conductive metals easily.

The popularity of plasma cutter has made it one of today’s most useful industrial cutting processes. If you are considering to buy a plasma cutter to different types of metal easily, we’ve listed the best plasma cutters to help you find the one that fits your needs.
