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 steel construction, 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 speeds positively effects:


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

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.

Functionality and easy operation

Excellent cutting results and high efficiency are the two main arguments for the plasma cutting technology:

  • Precise and continuous setting of the cuttingcurrent up to 80 A.
  • Cutting performance up to 30 mm.
  • Switch for: „perforated sheet cutting“
  • Portable, small and light weight: only 26 kg.
  • Supervision of the air pressure with warning indicator.
  • Air post flow time adjustable.
  • Plasma arc ignition with pilot arc.
  • Plasma cutting process without pilot current.
  • Central plasma torch connection for fast exchange of the torch.
  • Safe operation due to a thermic sensor mounted in the power modul.
  • Machine operation and adaption to robots possible (option).
  • Approved for operation in confi ned areas, S-symbol.
  • Cutting torch PR 81 with safety trigger preventing an unintentional operation.
  • Option: Digital read out for cutting current.
