Everything you need to know about Plasma Cutting

The process plasma cutting started wayback 1960's and was recognized as one of the ways to productively cut metal. In simple terms, Plasma Cutting is a way of cutting electrically conductive materials by means of jet of hot plasma. Some of the materials that can be cut through plasma cutting are steel, aluminium, copper as so on. Due to its efficiency combined with low cost, it is widely used from large metal fabrication companies to small welding dependent companies.

Advantages against traditional cutting:

Plasma cutting is very efficient when it comes to cutting thin and thick materials. What makes it stand out? Plasma Cutting produces very hot cone for cutting and can cut up to 38 mm steel, and even stronger torches can slice up to 150mm.

Other advantages:

1. Cleaner edge

2. Accurate Cutting

3. No metal chips  

Disadvantages:

1. up to 160 mm restriction for dry cutting and 120 mm for underwater cutting

2. High power consumption

3. Wider Kerf

Development

In its early stages, cutters used for plasma cutting are usually large and expensive, but because of technology such as CNC (Computer Numerical Control), plasma cutting machines are now flexible to cut many types of shapes according to the demand. 

Present Plasma Cutting

Today, the process have improved, as cutters now have smaller nozzle and thinner plasma arc, resulting to near-laser precision on plasma cut edges.
