Our best estimate for a cnc plasma cutting in this class — not a quote from Lincoln Electric. Configuration moves it a long way.
Overview
The Lincoln Electric Spirit III is listed as a mechanized plasma system whose cutting current depends on configuration, reaching up to 400 A with the top-tier power source, and whose mild steel production capacity is up to 80 mm on that basis. Lincoln Electric's current lineup has no model under this name, so read the listed figures as indicative and establish which power source a particular system actually has.
What stands out is the gas range. Plasma gas can be O2, N2, Argon-Hydrogen (H35) or air, and shield gas can be air, O2, N2 or H2O, in each case depending on the power source. In practice that points to oxygen for mild steel, with nitrogen or the argon-hydrogen mix and a water shield for stainless steel and aluminium, where an air cut would leave a heavily oxidised edge. The capacities follow: up to 60 mm in stainless steel and up to 50 mm in aluminium.
Every one of those numbers is tied to the power source, and the input power row says only that it is configuration dependent. A system built around a smaller source will not reach 80 mm, so a buyer comparing two used systems under this name has to compare amperage first. Supply is listed as 3-phase, 400 V / 480 V (50/60 Hz).
Motion is covered by a single row: up to 15,000 mm/min, marked as the rapid rate, with process cutting speed left to material and thickness. Kerf is listed at 1.5–4.0 mm depending on process and power source. The wide end of that range goes with high-current cuts in thick plate, and it sets a floor on hole diameter and slot width as well as on the spacing a nest needs.

Strengths & Limitations
Strengths
- Up to 400 A with the top-tier power source, with mild steel production cutting listed up to 80 mm
- Plasma gases listed as O2, N2, Argon-Hydrogen (H35) and air, so the process can be matched to the material
- H2O appears among the listed shield options, alongside air, O2 and N2
- Stainless steel listed up to 60 mm and aluminium up to 50 mm
- Rapid rate listed at up to 15,000 mm/min
Limitations
- Current, capacity and gas options are all power-source dependent, so the headline 400 A and 80 mm do not apply to every configuration
- Kerf runs from 1.5 mm to 4.0 mm, which limits small holes and narrow slots on thick plate
- Input power is listed only as configuration dependent, so the electrical service cannot be sized from the table
- Runs on a 3-phase 400 V / 480 V supply only

Frequently Asked Questions
01
With the top-tier power source, the listed figures give up to 80 mm in mild steel for production cutting, up to 60 mm in stainless steel and up to 50 mm in aluminium. The mild steel figure is marked as power-source dependent, so a lower-amperage configuration will cut less.
02
Plasma gas is listed as O2, N2, Argon-Hydrogen (H35) or air. Shield gas is listed as air, O2, N2 or H2O. Both lists are marked as power-source dependent, so check which gas console and source the system has before planning stainless or aluminium work around a particular process.
03
It depends on configuration. The listed figure is up to 400 A with the top-tier power source. No amperage is given for smaller sources and no input power figure at all, so the nameplate of the installed power source is the reference for both capacity and electrical service.
04
The listed figure is up to 15,000 mm/min, identified as the rapid rate. Process cutting speed is not given as a number because it depends on material and thickness. Use the cut charts for the installed power source to estimate cycle times.
