Plasma cutting three methods: air plasma cutting, traditional plasma cutting, high-precision plasma cutting. Below, we have to introduce everyone: high-precision plasma cutting airflow and protection technology.

High-precision plasma cutting uses dual gas technology. The plasma argon-hydrogen gas cutting method utilizes easily ionized argon gas and hydrogen gas with good thermal conductivity as the working gas, and the combination of the two forms an arc beam with strong energy density and a plasma beam with strong cutting ability. However, due to its relatively high price, it is generally used for the cutting of stainless steel and aluminum, which require a high quality of cuts. Plasma oxygen cutting has the characteristics of high cutting speed, small workpiece deformation, etc. because the working medium is high in dissociation heat, good heat carrying, and chemically active oxygen. The latest technology applications have led to a significant increase in electrode life.

Water mist protection Plasma cutting is evolved from the dual air flow process using water instead of shielding gas. Better cutting quality can be achieved when cutting stainless steel and aluminum, especially stainless steel and aluminum plates below 10 mm. This process is only used for machine cutting applications. Due to the use of water as a shielding gas, the cutting cost is significantly lower than that of the nitrogen/argon-hydrogen mixture process.
