Benefits of Plasma Marking by CNC Plasma Cutting in Nottingham

If you have been associated with the plasma marking or plasma cutting industry, it probably has not missed your attention that works related to both the actions require similar source of power, control and consumables that are frequently used in both the procedures. Both actions of cutting and marking being done on the same table reduce trouble in effective material handling and also save time in the process.

The plasma marking procedure might require 5 to 30 amps current depending on the element and depth of the material. The plasma arc might cause discoloration at lower amperage due to deposited heat flux for creating the mark. This procedure of marking with CNC plasma cutting device modifies the top surface layer of the material. The arc vaporises only a tiny amount of the material. As argon is a monoatomic gas with low-energy content, it is frequently used in Nottingham as a plasma gas for surface marking.

At slightly higher amperage, the plasma arc melts and vaporises a little large amount of material to create a permanent mark. With the help of varying process parameters, a fabricator can have a control over the width and depth of the mark. This mark is usually visible through a thick coat of paint or even after years of its exposure to a corrosive environment. Marking with CNC plasma cutting machine can create dimples that facilitate punching or beginning of a drill.

Nitrogen is a common choice as plasma gas for a deeper mark on the material. The type of gas might differ depending on the material to be marked with the CNC plasma machine. However, in almost all cases of high precision plasma systems, same kind of shielding gas is used. The level of precision can change with high amperage consumables used in the process.

Usually, all sorts of plasma power sources can produce plasma marks. In order to obtain the most precise marks, shapes and equal depth, a fabricator should use a high-end CNC machine.
