What is the difference between plasma torches?

When it comes to precision metal cutting, plasma technology offers versatile solutions tailored to various applications. Understanding the differences between touch (non-pilot arc) and non-touch (pilot arc) plasma torches, is crucial in selecting the appropriate tool for your needs.

Touch (Non-Pilot Arc) Plasma Torches

Touch plasma torches utilize the drag touch technology. This technology requires the torch tip to be in close contact with the material being cut. These torches expel plasma for cutting upon contact with the metal surface. Therefore, making them ideal for cutting metal plates and thin sheet metal. However, surface preparation is crucial, as any coatings, paint, or rust must be removed to ensure proper plasma ejection.

Non-Touch (Pilot Arc) Plasma Torches

In contrast, non-touch plasma torches generate an electric arc prior to nozzle contact, thanks to a high-frequency discharge of plasma. This pilot arc technology eliminates the need for direct contact with the metal, making it preferred for cutting thick metals while still capable of handling metal sheets effectively. Non-touch plasma cutting technology allows for greater distance between the cutting tip and the workpiece without compromising arc stability.

Selecting Your Plasma Cutter

Whether you’re a professional or a DIY enthusiast, the choice between touch and non-touch plasma cutters varies. It depends on your preferences and the specific requirements of your cutting task. Understanding the advantages and limitations of each plasma torch type is crucial. This knowledge helps you make informed decisions and achieve precision and efficiency in your metalworking projects.
