Merkle Plasma Cutting Units - The efficient alternative!

Plasma cutting with compressed air is being used more every day as an alternative to acetylene cutting. All conductive metals, hardened or non-hardened steels, alloys, aluminium and its alloys, copper, brass, cast iron and titanium can be easily cut with plasma. Plasma cutters are used in various branches as steelconstruction, assembly works, repairs, automobile repairs etc. The success of plasma cutting is simply the plasma beam, an electric arc, which produces an extremely narrow and intensive arc, with limited heat. The arc temperature is approximately 13000°C. Under this intensive heat the work piece heats so quickly that lateral heat transfer is limited to aminimum. This heat concentration, combined with an applied energy of 106 W/cm2 provides rapid cutting and a small cut. Narrow cut width with high linear cutting speedspositively effects:

  • Less raw material consumption.
  • Low energy costs.
  • Less material distorsion.
  • Reduced wages.
  • Better logistic requirement.s.

Cutting performance

Cutting performance, cutting speed and current depend on each other. The diagram shows the cuttingspeed in relation to the cutting performance for different currents.

Operating costs

An important factor in cutting materials is always the use and price of the carrier gas. Compressed air is easily available for a very low price. Due to a low demand quantity of the compressed air, the plasma cutting is a very economical method.
