Overview
The ESAB Cutmaster 180i is a heavy-duty inverter-based plasma cutting system delivering 180 amps for demanding industrial cutting applications. As the flagship of ESAB's Cutmaster series, the 180i is engineered for high-productivity cutting of mild steel, stainless steel, and aluminum up to 1-1/2 inches at rated quality, with severance capability extending to 2 inches on mild steel. The inverter power design provides improved power factor and energy efficiency compared to transformer-based plasma systems of equivalent output, reducing operating costs in high-utilization environments.
The Cutmaster 180i uses ESAB's SL100 mechanized torch, a water-cooled torch designed for CNC table mounting and extended production cycles. The SL100 torch accepts a range of consumable configurations for different materials and thicknesses, including standard cutting consumables and fine-cut configurations for improved edge quality on thin and medium gauge material. The torch connects to the power supply via a robust lead assembly rated for continuous production duty, and ESAB offers both straight and 75-degree torch body configurations to accommodate different table mounting orientations.
A distinguishing feature of the Cutmaster 180i is its inverter architecture, which enables true constant-current output regardless of input voltage fluctuations within its specified range. This stability is particularly valuable in industrial facilities where voltage sag from other heavy equipment on shared electrical circuits can cause arc instability on lesser plasma systems. The 180i's power factor correction circuit also reduces harmonic distortion on facility power, a consideration for plants with sensitive equipment on shared circuits or utility power factor penalty billing.
The Cutmaster 180i integrates with CNC plasma tables through a standard machine interface that provides arc voltage output for height control systems, remote current control, and pilot arc management compatible with most major CNC controllers. ESAB supplies interface cables and documentation for integration with Vision CNC and common third-party controllers. The unit can also be configured for hand cutting operations using ESAB's SL60 or SL100 hand torch, providing shop versatility for operations that need both CNC table production and manual cutting capability.
Power requirements for the Cutmaster 180i are three-phase at 380/460V, drawing approximately 70A per phase at maximum output. The system includes a built-in air plasma filter and pressure regulator, though ESAB recommends upstream refrigerated air drying for consistent consumable life, particularly in high-humidity environments. Compared to the Cutmaster 120i, the 180i provides meaningfully higher throughput on material from 1/2 inch upward and extends the practical cutting range for structural fabrication applications requiring reliable 1-1/2 inch capacity.

Strengths & Limitations
Strengths
- Inverter architecture delivers stable constant-current output regardless of input voltage variation
- Power factor correction reduces harmonic distortion and utility demand charges
- SL100 water-cooled machine torch designed for sustained high-duty-cycle CNC production
- Dual-use capability for CNC table and hand cutting with torch changeover
- Substantially higher throughput than Cutmaster 120i on material from 1/2 in upward
Limitations
- Inverter electronics require more specialized service than transformer-based systems
- Cut quality on stainless steel is limited by air/O2 gas options versus N2/F5 in HD systems
- 190 lb weight makes repositioning between workcells inconvenient without a cart

Frequently Asked Questions
01
The Cutmaster 180i delivers 180 amps versus 120 amps on the 120i, extending rated cut capacity from 1 inch to 1-1/2 inches and providing significantly higher production speed on material from 1/2 inch through 1 inch. The 180i uses the larger SL100 water-cooled torch versus the SL60 on the 120i, and requires three-phase 380/460V power versus the 120i's single or three-phase capability. The 180i is a heavier-production machine.
02
The Cutmaster 180i is compatible with any CNC plasma table through its standard machine interface output, which provides divided arc voltage for THC systems and remote start capability. ESAB provides integration documentation for Vision CNC and publishes interface specifications for third-party controller integration. Most major table brands — Messer, Koike, and others — support the Cutmaster 180i as an alternate plasma source.
03
Yes. The Cutmaster 180i supports both compressed air and oxygen plasma gas, with oxygen providing improved cut quality and speed on mild steel compared to air. Oxygen plasma produces a cleaner cut face with less oxidation in some thickness ranges. An external oxygen supply (cylinder or manifold) is required; the machine's built-in filter/regulator handles both air and oxygen.
04
The Cutmaster 180i is rated at 60% duty cycle at maximum 180A output, meaning it can cut for 6 minutes out of every 10 at full amperage before requiring a cooling period. At reduced amperages (e.g., 100-140A for lighter material), duty cycle increases substantially, and the system can sustain near-continuous production cutting. The SL100 water-cooled torch supports the higher duty cycles the power supply allows at reduced output.
05
ESAB SL100 consumables (electrode, nozzle, shield cup, swirl ring) are competitively priced with Hypertherm Powermax-series consumables. Availability is strong through ESAB's distribution network and major welding supply distributors. Life expectancy on the SL100 consumables is comparable to air plasma systems of similar amperage class, though it does not match the LongLife ratings of Hypertherm's XPR-series HD consumables.
