Miller portable air plasma cutter
Miller Spectrum 625 X-TREME Plasma Cutter Machine Support
The Spectrum 625 X-TREME is a 120-240 V single-phase air plasma cutting and gouging system with Auto-Line circuitry, an XT40 torch, MVP adapters, and 30/40 amp consumable options. This page follows Miller specification sheet PC/9.6, issued October 2019.
Start Here
Use the shortest path for the machine, torch, consumables, or cutting problem you are trying to solve.
Replace the XT40 torch
The sheet lists 12 ft. and 20 ft. XT40 hand-held torches. Confirm cable length before ordering.
Find consumables
XT40 cutting parts are shared across the 30 A and 40 A configurations; gouging uses a separate tip and shield.
Check cut quality
Start with the correct air supply, tip, drag shield, electrode, standoff, and material thickness.
Use it with an engine drive
Miller lists compatibility with an engine-driven welder or generator that has a 240 V receptacle of 4 kW or more.
Open the family chart
Use the broader Miller Spectrum table when the machine is a different Spectrum model or the torch family is uncertain.

Cutting and Gouging Notes
Use the correct configuration for the work and verify the air supply before diagnosing the torch.
- At 40 A on 240 V, the sheet lists 1/4 in. mild steel at approximately 64 ipm and 5/8 in. at approximately 13 ipm.
- At 27 A on 120 V, the sheet lists 1/8 in. mild steel at approximately 88 ipm and 3/8 in. at approximately 15 ipm.
- Recommended maximum piercing is 5/16 in. for handheld cutting at 40 A and 1/8 in. at 27 A.
- For aluminum and other high-thermal-conductivity metals, Miller notes that cutting capability may be reduced by as much as 30%.
- For 30 A cutting, use the 30 A tip and drag shield. For 40 A cutting, use the 40 A tip and drag shield.
- For gouging, replace the cutting tip and drag shield with the XT40 gouge tip and gouge shield. The deflector improves arc visibility while maintaining a 1/16 in. standoff.
