Plasma Cutting

Why plasma cutting

Plasma cutting: why does gas determine cutting quality?

Plasma cutting is a thermal process for machining conductive metals. A high-speed gas combined with an electric arc generates plasma, which transfers heat to the material until it melts. SIAD has developed, together with leading equipment manufacturers, a range of gases and mixtures optimized for every material and thickness.

Precision

Cut surface quality and cutting stability

Duration

Consumable parts that last up to 3 times longer than with compressed air

Speed

High cutting speeds on greater thicknesses with HYDRAPRO mixtures

The PRO line

PRO is the line of pure gases and mixtures dedicated to plasma applications, developed in collaboration with the leading operators in the sector to keep pace with the continuous evolution of this technology. It includes gases needed to promote the removal of metal brought to the molten state from the cutting zone and to shield the cut surface from atmospheric air and assist gases, as well as highly ionizing gases capable of generating high-energy plasma jets.

Gas distribution systems

SIAD designs and builds turnkey gas distribution systems according to the most advanced quality and safety criteria. Checks, testing and maintenance: each system is tested and verified with leak tests according to qualified procedures (with reference to UNI EN737/3 and UNI11627:2016). Periodic maintenance can be included in the supply contract.

Products and services for plasma cutting

For plasma cutting, SIAD offers specific combinations of plasma gas and assist gas for each material and thickness. Each combination is the result of trials conducted directly with equipment manufacturers, to guarantee cutting quality and productivity for every application.

Technical Oxygen

Used as plasma gas in the cutting of carbon steels and alloy structural steels. The exothermic reaction with iron ensures clean cuts, free of dross and burrs, with high speeds and a reduced heat-affected zone.

LaserPRO Oxygen

To be used always in the cutting of carbon steels and alloy structural steels. Thanks to its extremely high degree of purity, it optimizes the exothermic reaction with iron, ensuring superior performance: even cleaner and sharper cuts, absence of dross and burrs, higher process speeds and an even more reduced heat-affected zone, for top-level finishing quality.

LaserPRO Nitrogen

To be used in plasma cutting of stainless steels, aluminum and non-ferrous alloys. The high purity ensures clean cuts, free from oxidation and with excellent edge quality, reducing secondary processing. It also ensures process stability and a limited heat-affected zone.

HydraPRO mixtures: used as plasma gas in so-called “high-definition” systems, they make it possible to exploit to the fullest the dissociative and reassociative properties of Hydrogen, significantly improving the qualitative parameters of cutting. The most used are HYDRA PRO H-35 and HYDRA PRO H5N.
