Hypertherm says that there are a number of myths surrounding the use of plasma cutting systems. Here common questions about plasma cutting technology are answered.
Q. What are the advantages of using plasma cutting on thin materials?
A. On thin materials plasma cutting affects a smaller portion of the material and produces less warping than oxyfuel cutting.
Q. Can plasma be used to cut thick materials?
A. Yes. A couple of decades ago plasma was only suitable for cutting thin materials, but technological advances now mean that plasma machines provide excellent results up to thicknesses of at least 44mm (1.75 inches).
Q. How do you choose between using plasma and oxyfuel cutting?
A. For very thick materials oxyfuel cutting is still most effective, but given a choice it delivers cleaner cuts as well as being quicker and more productive to utilise the full range of plasma cutting tools.
Q. What materials is plasma cutting suitable for?
A. Plasma cutting systems are ideal for use on any electrically conductive metal, including:
- stainless steel
- aluminium, and
- mild steel
A. Yes. Plasma cutting is much more efficient when cutting stainless steel and aluminium as well as for cutting through steel that is dirty, painted or rusted.
Q. Are plasma systems limited to cutting?
A. No. Plasma systems are highly versatile and are available in handheld, portable and X-Y table compatible versions. They can be used for a range of applications, including:
- piercing, and
- gouging, for which it is particularly suited, producing less noise and smoke than other methods.
