CB70 TORCHES

TECHNICAL FEATURES

For years, this has been a widespread and appreciated technology within the industry. A jet of plasma gas melts material in the cutting area and removes it, leaving a well-cut line. Through its special nozzle, the torch dispenses an inert gas. Through this gas, an electric arc is formed between an electrode and the material in the process of being cut. The electric arm transforms gas into plasma. The very high plasma temperatures (approximately 10,000°C) bring the material to be cut to the melting temperature, the molten metal is evacuated from the melting groove and cutting is carried out. There are then several methods for cutting the plasma: the choice is based on a variety of factors, such as the degree of precision of the cut and its mechanical or manual implementation. Beside conventional cutting, we can remember dual gas systems, with water and precision screen.
Plasma is considered the fourth state of material. It is a highly ionised gas and is an excellent electrical conductor. The reproducibility of plasma in an industrial and repetitive way is carried out through a device called a torch.

PLASMA CUTTING, UNDENIABLE BENEFITS

• Considerable cutting speed
• High precision at edges
• Good cost-bene t ratio
• Multiple applications
• Plasma cutting is in fact suitable for all electrical conductive materials.

PLASMA ARC USES

Thanks to plasma cutting it is possible to cut both thin sheets and considerable thicknesses. There are many plasma cutting applications in the industrial sector. The cutting of stainless steel, carbon steel and aluminium sheets of different thicknesses is particularly used in the transport industry as well as in the refrigeration and air conditioning field.
The ability to cut very thick slabs is especially valuable in the naval industry, but also for the creation and machining of pressure vessels, as well as earth moving vehicles. Plasma cutting effectively lends itself to the contoured cutting of tubes and other cylindrical materials, for the creation of grooves and inclined cuts, as well as for bending, perforation and gouging processes.
