Miller Spectrum 625 X-TREME
Dual-Voltage 40AThe Miller Spectrum 625 X-TREME replaces the Hobart Airforce 40i in this guide after the Hobart went out of stock on Amazon. It is the closest match Amazon still sells: the same 40A class, the same 5/8-inch rated cut and 7/8-inch sever on mild steel, and the same XT40 torch family, since Hobart and Miller are sister brands. Auto-Line accepts any single-phase input from 120V to 240V without relinking, giving 40A at 50% duty cycle on 240V and 27A at 20% on 120V. It costs roughly $850 more than the Hobart did, and at about 21 lbs with the 12 ft torch it is easy to carry around the shop.
Pros
- Auto-Line runs on any 120V to 240V single-phase outlet
- Rated 5/8-inch cut and 7/8-inch sever on mild steel
- 40A at 50% duty cycle on 240V
- About 21 lbs with the 12 ft torch
- XT40 torch consumables are widely stocked
Cons
- Costs more than the Hypertherm Powermax 45 SYNC at current prices
- Only 27A at 20% duty cycle on a 120V outlet
- Needs 6 SCFM at 90 PSI, more than a small pancake compressor supplies
- Consumables cost more than budget import brands
Our Verdict
The Miller Spectrum 625 X-TREME is the pick for shops that need one 40A cutter to run on both 120V and 240V. It matches the Hobart it replaces on cut capacity and torch, but it is no longer the mid-priced option: if you have 240V, the Hypertherm Powermax 45 SYNC costs about the same and adds 5A.

Plasma Cutter Buying Guide
Choosing the right plasma cutter means understanding output, consumables, and how you will use the machine, whether handheld, on a CNC table, or both:
Plasma Cutting Machine Guide: Cut Capacity, Power and CNC Needs
Updated 2026. A plasma cutting machine (plasma cutter) uses compressed air and an electric arc to melt and blow through conductive metal. Pick the machine by the thickest steel you need to cut cleanly, then by whether it will be handheld or run on a CNC table. This table shows the typical clean cut capacity for each amperage range. Severance capacity (the maximum the machine can cut at a crawl) is usually 1.5 to 2 times the clean cut rating, so always size on the clean cut number.
| Output Amperage | Clean Cut Capacity (Mild Steel) | Input Power | Best For |
|---|---|---|---|
| 20A to 30A | Up to 1/4" | 120V | Light sheet metal, hobby and art work |
| 40A to 50A | Up to 1/2" | 120V / 240V dual voltage | Home shop, auto repair, trailers |
| 60A to 80A | Up to 3/4" | 240V single phase | Fabrication and light production |
| 85A to 105A | 1" and thicker | 240V or three phase | CNC production and heavy plate |
What Makes a Plasma Cutter CNC-Ready?
A CNC plasma cutter is a plasma cutting machine that is driven by a CNC table instead of by hand. Not every plasma cutter can do it. A CNC-ready plasma cutter must have these features, which budget handheld machines usually lack:
| CNC-Ready Requirement | Why It Matters |
|---|---|
| Machine torch (mechanized torch) | Mounts on the gantry; a handheld torch cannot be driven by the table. |
| Machine interface (start signal and ok-to-move) | Lets the CNC controller fire the torch and know when the arc transferred. |
| Divided arc voltage output | Feeds torch height control so the standoff stays correct as the plate warps. |
| Non-contact pilot arc (blowback start) | Avoids the high-frequency start that interferes with CNC electronics. |
| Rated duty cycle at your cutting amperage | CNC tables cut for minutes at a time, so a low duty cycle machine will stop on overheating. |
| Clean, dry compressed air | Wet or oily air shortens consumable life and ruins the cut edge. |
For a CNC table, our pick is the Hypertherm Powermax 65 SYNC, which is built for machine torch use. Budget handheld units such as the Lotos LOP55D are for cutting by hand.
Frequently Asked Questions
What amperage plasma cutter do I need for my shop?
For casual shop use and material up to 1/2-inch mild steel, a 45A plasma cutter is sufficient. For regular production cuts on 3/4-inch and heavier material, step up to a 65A machine. Industrial work on 1-inch and above requires 85A+ units. Always size up if you plan to use the cutter on a CNC table.
What is the difference between cut capacity and severance capacity?
Cut capacity (or rated cut) is the maximum thickness the machine cuts at a quality, production-ready speed. Severance capacity is the absolute maximum thickness the machine can pierce through, though at very slow speed with a rough edge. Always spec your machine based on cut capacity, not severance capacity.
What air supply does a plasma cutter need?
Most plasma cutters require a clean, dry air supply at 70-120 PSI and 4-8 CFM. A standard 20-gallon shop compressor works for light duty use, but extended cutting sessions require a 60-gallon or larger compressor to maintain pressure. Always add a moisture separator and filter to your air line to protect consumables.
Can I use a plasma cutter on a CNC table?
Many plasma cutters include a machine torch interface (trigger signal) and pilot arc that are compatible with CNC plasma tables. The Hypertherm Powermax SYNC series, including the Powermax 65 SYNC, is specifically designed for CNC use. Budget units often lack the machine interface required for CNC tables. Always verify CNC compatibility before purchasing.
How much does a good plasma cutter cost?
Entry-level plasma cutters start around $300-$400 for 40-50A machines. Professional units from Hypertherm, Miller, and Lincoln range from $1,100 to $3,200+. CNC-ready machines with full automation interfaces start around $2,200 and reach $5,000+ for production-grade units. Factor in consumable costs: tips and electrodes run $20-$60 per set depending on brand.
What is a CNC plasma cutter?
A CNC plasma cutter is a plasma cutting machine mounted on a computer-controlled table that moves the torch along a programmed path. It cuts repeatable shapes in steel plate with a CNC-ready plasma source, a machine torch, and torch height control.
Can any plasma cutter be used on a CNC table?
No. The plasma cutter needs a machine interface to take a start signal from the CNC controller, a non-contact pilot arc, and ideally a divided arc voltage output for torch height control. Handheld budget machines usually lack these, so check the specifications for CNC or machine torch support before buying.
What thickness can a 45 amp plasma cutter cut?
A 45 amp plasma cutter cleanly cuts mild steel up to about 1/2 inch to 5/8 inch, and can sever up to about 3/4 inch at a slow travel speed. For regular cuts above 5/8 inch, step up to a 65 amp machine.
