How much does the Thermal Dynamics Cutmaster 101 cost?
Estimated price range
Our best estimate for a cnc plasma cutting in this class — not a quote from Thermal Dynamics. Configuration moves it a long way.
Overview
The Thermal Dynamics Cutmaster 101 is an air plasma power source with a listed maximum output of 100 A and 10 kW, a recommended mild steel cut of 38 mm (1.5 in) and a severance figure of 50 mm (2 in). It is not in the maker's current lineup, so this page is a reference for anyone weighing up a used unit.
The listed figures split capacity by material. Mild steel is 38 mm (1.5 in) recommended, while stainless and aluminum are each 25 mm (1 in) recommended. Only mild steel has a severance figure. A shop that cuts mostly stainless or aluminum should size the machine on the 25 mm (1 in) number and ignore the headline one.
Duty cycle is listed as 60% at 100A and 100% at 68A. Full output therefore suits hand cutting and shorter table programs. Nests that keep the arc on for long periods need to run at or below 68A, with whatever thickness that current allows.
Two rows matter for table use. The torch row names the SL100 hand torch and the SL100T machine torch for CNC or mechanized work, and the arc voltage output row is marked yes, for CNC torch height control. Gas is air as standard, with nitrogen optional.
The input side is the flexible part: 208/240 VAC single-phase or 208–480 VAC 3-phase, with Auto-Line auto-sensing listed. Certifications are given as CE, CSA and UL.

Strengths & Limitations
Strengths
- Listed input accepts 208/240 VAC single-phase or 208–480 VAC 3-phase, with Auto-Line auto-sensing
- Recommended mild steel cut of 38 mm (1.5 in), with 50 mm (2 in) severance
- The SL100T machine torch and an arc voltage output for torch height control are listed for CNC use
- 100% duty cycle at 68A in the listed figures
- Air is the standard gas, so no bottled gas is needed for the basic setup
Limitations
- At the full 100A the listed duty cycle is 60%
- Stainless and aluminum are listed at 25 mm (1 in) recommended, well under the mild steel figure
- No pierce capacity or cut speed rows are listed, so mid-plate starts and cycle times cannot be planned from this table
- Nitrogen is an option, not part of the standard air setup

Frequently Asked Questions
01
The listed figures are 38 mm (1.5 in) recommended and 50 mm (2 in) severance in mild steel, and 25 mm (1 in) recommended in both stainless and aluminum. No severance figure is listed for stainless or aluminum.
02
The listed figures point that way. The torch row includes the SL100T machine torch for CNC or mechanized cutting alongside the SL100 hand torch, and the arc voltage output row is marked yes for CNC torch height control. Check that a used unit comes with the machine torch.
03
Either 208/240 VAC single-phase or 208–480 VAC 3-phase. The Auto-Line row describes universal 1-phase or 3-phase operation with 208–480V auto-configuration, so the unit is listed as adapting to the supply it is connected to.
04
The listed duty cycle is 60% at 100A and 100% at 68A. Cutting at the full 100 A maximum has to include rest time, while work at 68A or below can run without planned pauses.
