Excellent Enterprises Plasma CUT-70 Three Phase MOSFET Inverter Cutting Machine
The Fabricator’s Sweet Spot Between Workshop Portability and Industrial Cutting Power
Not every fabrication operation needs a 100 Amp industrial plasma beast.
But entry-level plasma cutters often fall short when thicker plate, structural profiles, and production workloads enter the picture.
That’s exactly where the Excellent Enterprises Plasma CUT-70 Three Phase MOSFET Inverter Cutting Machine dominates.
Engineered as the ideal mid-capacity industrial plasma solution, this 70 Amp three phase air plasma cutting machine delivers the performance range most fabrication businesses actually require—without the capital burden, infrastructure complexity, or overspec cost of ultra-heavy industrial systems.
For structural fabricators, sheet metal processors, gate manufacturers, HVAC contractors, infrastructure maintenance teams, and medium-scale workshops, the CUT-70 represents the most commercially practical cutting power tier.
High-Frequency MOSFET Plasma Dynamics
Precision Arc Behaviour That Fabricators Notice Immediately
The advanced MOSFET inverter power platform operates at elevated switching frequencies, generating a tightly concentrated plasma column with excellent arc rigidity.
Real-world cutting advantages include:
✔ Stable plasma jet geometry
✔ Reduced arc wander during long cuts
✔ Better edge straightness
✔ Lower kerf taper on thicker sections
✔ Cleaner underside finish
✔ Reduced dross adhesion
✔ Improved profile accuracy
✔ Lower consumable wear rates
In fabrication terms:
Less cleanup. Less correction. Faster dispatch. Better profitability.
Built for Imperfect Real-World Metal Conditions
Fabrication shops rarely work with pristine laboratory-grade material.
Operators regularly encounter:
- Painted structural steel
- Oxidized plate
- Galvanized fabrication sections
- Scrap metal recovery material
- Coated industrial assemblies
- Perforated sheet
- Expanded mesh
- Metal grating
The integrated HF Pilot Arc ignition system enables instant non-contact arc transfer without demanding clean torch contact.
This dramatically improves operational efficiency where conventional contact-start systems become frustrating and consumable-heavy.
