Variations of the Plasma Cutting Process

Precision Plasma Cutting

This process produces superior cut quality on thinner materials, (less than 1/2") at slower speeds. This improved quality is a result of using the latest technology to super constrict the arc, dramatically increasing energy density. The slower speeds are required to allow the motion device to contour more accurately. This process is for mechanized applications only


Precision Plasma Cutting

Conventional Plasma Cutting
This process generally uses a single gas (usually air or nitrogen) that both cools and produces the plasma. Most of these systems are rated at under 100 Amps, for cutting materials under 5/8" thick. Primarily used in hand held applications
Conventional Plasma Cutting 

Dual Gas Plasma Cutting
This process utilizes two gases; one for the plasma and one as a shield gas. The shield gas is used to shield the cut area from atmosphere, producing a cleaner cut edge. This is probably the most popular variation, as many different gas combinations can be used to produce the best possible cut quality on a given material.
Dual Gas Plasma Cutting

Water Shield Plasma Cutting
This is a variation of the dual gas process where water is substituted for the shield gas. It produces improved nozzle and workpiece cooling along with better cut quality on stainless steel. This process is for mechanized applications only.
Water Shield Plasma Cutting

Water Injection Plasma Cutting
This process uses a single gas for plasma and utilizes water either radially or swirl injected directly into the arc to greatly improve arc constriction, therefore arc density and temperatures increase. This process is used from 260 to 750 amps for high quality cutting of many materials and thicknesses. This process is for mechanized applications only.
