UNIMIG ENVY CUT 120 PLASMA CUTTER
UNIMIG ENVY CUT 120 Plasma Cutter (U11540)
UNIMIG ENVY CUT 120 Plasma Cutter – 120A, 415V Three Phase (U11540)
The UNIMIG ENVY CUT 120 is a 120-amp, 415V three-phase industrial plasma cutter that delivers a 50mm clean cut and 70mm severance on mild steel at 100% duty cycle. It runs handheld or on a CNC table, includes a 6m SC160 torch, and is backed by UNIMIG's 5-year warranty. It suits fabrication shops, structural steel, heavy plant repair and any workshop that needs to cut thick plate all day without stopping.
What sets it apart: most plasma cutters in this class drop to a 60–80% duty cycle at full output. The ENVY CUT 120 holds 100% at 120A (at 40°C), so on long cuts and production runs the machine is never the bottleneck.
Cutting performance
| Material | Clean cut | Severance |
|---|---|---|
| Mild steel | 50 mm | 70 mm |
| Stainless steel | 45 mm | – |
| Aluminium | 40 mm | – |
| Copper | 25 mm | – |
Output is adjustable from 20A to 120A, so the same machine handles thin sheet and heavy plate.
Built for the workshop and the worksite:
-
5" colour LCD touchscreen – Smart-Set programs let you pick cut type, material and thickness and the machine sets itself. 100 job memories store your proven settings for recall.
- Three cutting modes – solid plate, perforated (grating, mesh and expanded metal without arc dropout) and gouging for removing welds and defects without grinding.
- CNC connectivity – plug in a CNC torch and run it on a cutting table for repeatable automated cuts, then switch back to handheld when the job calls for it.
- Automatic digital air pressure regulation – the machine sets its own air pressure to suit the selected mode. No manual regulator adjustment, and an Air Test function to confirm flow before you cut.
- Pilot arc start – strikes without touching the workpiece, so it cuts through paint, rust and scale and extends consumable life.
- 2T/4T trigger modes – lock the arc on for long cuts to reduce hand fatigue.
- Smart Fan – runs only when needed, cutting noise, power draw and the dust pulled through the machine.
- Generator compatible – runs off a generator of 26kVA or larger for remote and site work.
- IP21S rated, Insulation Class H, built to AS 60974.1.

Frequently Asked Questions
Does the UNIMIG ENVY CUT 120 need three-phase power? Yes. The ENVY CUT 120 runs on 415V three-phase power with a 32A supply plug. It cannot be run from a standard 240V single-phase outlet. If you only have single-phase power, ask the QWS team about UNIMIG's single-phase plasma range.
How thick can the ENVY CUT 120 cut? It makes a 50mm clean cut and 70mm severance cut on mild steel, a 45mm clean cut on stainless steel, 40mm on aluminium and 25mm on copper.
What is the duty cycle of the ENVY CUT 120? 100% at 120A at 40°C. It can cut continuously at full output without a cooling pause.
Can the ENVY CUT 120 be used on a CNC plasma table? Yes. It has a built-in CNC interface. Connect a CNC torch and it will run on a cutting table for automated, repeatable cuts, and it still works as a handheld unit with the supplied SC160 torch.
What size air compressor does the ENVY CUT 120 need? It draws 140–330 L/min at 3–7 bar. The onboard digital regulator sets the pressure automatically, so your compressor only needs to deliver clean, dry air above the minimum flow and pressure.
Can the ENVY CUT 120 run off a generator? Yes, UNIMIG recommends a generator rated at 26kVA or higher.
Can the ENVY CUT 120 gouge? Yes. Gouging mode removes welds, defects and unwanted material without grinding.
What torch comes with the ENVY CUT 120? A 6m SC160 plasma torch, plus a 4m 300A earth clamp and lead.
What is the warranty on the UNIMIG ENVY CUT 120? 5 years from UNIMIG. Register the warranty online after purchase.
