Plasma cutting is the fastest cutting process on carbon steel, aluminum, or stainless steel.
Plasma is defined in Websters as a ”collection of charged particles ... containing about equal numbers of positive ions and electrons and exhibiting some properties of a gas but differing from a gas in being a good conductor of electricity ...”.
Like any cutting process, there are a lot of variables that affect plasma cut quality.
Under water plasma cutting is nothing new - it was first done in the mid 1970's. But it still has many advantages that lead many fabricators, steel service centers, and manufacturers to prefer it over dry cutting. An "Air Curtain" or "Bubble Muffler" is used to create a pocket of air around the front end of the torch, shielding the arc from the water. But not every thickness of every material can be cut under water. So what are the limits, and what happens if you push them?
There are a lot of things that can cause problems with plasma torch consumable life, and troubleshooting a problem can be complicated and time consuming. So we’ve put together a list of common things that you can look for if you are having problems, or if you just want to make sure you are getting the most from your CNC plasma system.
