Plasma cutter

Almost every metalworking plant is equipped with a plasma cutter. The plasma cutting process involves arc ignition, which is then directed through a nozzle to cut the sheet metal. The most popular and cheapest shielding gas is air drawn from a compressor. In more advanced plants where very high-quality cuts are needed, air-oxygen, oxygen-hydrogen, or oxygen-nitrogen mixtures are used.

Plasma cutters - How does CNC plasma cutting work?

There are two types of plasma cutters: for manual cutting and mechanized CNC cutting. Machine torch cutting is done on a table of any size, where the sheet metal is placed and the pre-designed drawing is uploaded to the CNC console. The automation of all welding and plasma cutting processes is driving more people to purchase tables and cut metal parts using plotters.    

What factors should you consider while buying a plasma cutter?

When deciding to purchase a plasma cutter, you can focus your choice on products from professional manufacturers like Hypertherm, Cebora, or Thermal Dynamics, or opt for equipment produced in distant Asia. The level of technology from Chinese manufacturers ensures that you can purchase devices of very good quality, therefore with proper maintenance a plasma cutter can serve us for many years. We invite you to explore the offering of Weldcut, a welding equipment store. If you have any doubts or hesitations, feel free to contact our customer service for assistance.

How does a plasma cutter work?

Plasma cutters are industrial devices used for cutting metal elements of any shape and thickness. To enable cutting, stream of plasma is required. This is a gas composed of ions, electrons, and (not necessarily) neutral particles.

The operation of plasma cutters involves connecting the metal workpiece, which is to be cut, to the negative terminal. The positive terminal is connected to the torch head, where the plasma stream is generated. During operation, the metal is heated to a high temperature and begins to melt. As the metal melts, a plasma stream is created, which cuts through the metal workpiece. Plasma cutting is therefore an extremely efficient and effective method for cutting steel.

A plasma cutter must be connected to a suitable power source with the required voltage (230V). The next step involve connecting to the earth clamp. Check the details before first use in the manual and on the device panel. After connecting, use the cutting effect, recommended at about 20-30% of the tool's maximum potential and the ionization time.
