An essential tool for cutting and dismantling metal quickly and flexibly, the plasma cutter is used to carry out the work of metallurgists, bodyworkers, and boilermakers. Since plasma is an ionized conductive gas, it creates a high temperature that can cut sheets with a thickness ranging from 2 mm to 40 mm.
To generate the electric arc and facilitate metal cutting, this device needs:
- an inverter that transforms alternating current into direct current at 230 V or 400 V;
- a clamp and a ground cable;
- a torch;
- guidance equipment.
A plasma cutter is used in a ventilated space outdoors. Emitting a lot of smoke, its use requires wearing respiratory protective gear. To start it, it is necessary to place the ground clamp on the sheet to be cut. Then, approach the torch to cause remote ignition and produce the metal's melting state. To ensure a regular cut, it is necessary to maintain the torch at a proper distance. Here is a summary of plasma cutters:
- portable plasma cutter;
- plasma cutter with built-in compressor;
- plasma cutter with external compressor;
- smart plasma cutter;
Other accessories are also essential for plasma cutting:
- the emitting electrode;
- the nozzle;
- the diffuser;
- the nozzle cap;
- the shield cap.
A plasma cutter requires a compressor to produce air and expel the molten metal droplets. With an integrated compressor, the plasma cutter becomes more convenient and efficient. With an auxiliary compressor, the use of an oil separator is necessary. Durable plasma cutters are preferred for carrying out the work. The inverter technology also facilitates settings to ensure more efficiency.
