Diagnose Better. Cut Cleaner. Waste Less.
Bad cut?
Find the cause.
Cut Doctor by Dry Air walks you through the most likely causes of a bad plasma cut, one inspection at a time, grounded in your machine's documentation.
Free to start. AI photo analysis is included with paid plans.
Example · Excessive bottom dross · Handheld
1. Travel speed too slow
Heavy, bubbly dross
2. Worn nozzle
Consumables not new
3. Torch too high
No standoff setting
Dashed = checks to make, not conclusions.
Built for the shop floor
Photo-assisted cut diagnosis
Snap the bottom edge or cut face. Cut Doctor flags what it can see — and says plainly when it can't tell.
100 machine references
50 CNC tables and configurations, 50 hand-torch plasma units, each with an honest manual-status label.
Guided troubleshooting
One check at a time, ranked by evidence. Works offline in a metal building with no signal.
Verified vs. suggested — always clear
Manufacturer specs look different from suggestions. Cut Doctor never invents amps, speeds, or heights.
Air system health
Inspection checklists, filter service reminders, and a record of what you found.
Shop history
Every case, fix, and photo saved to the machine — so the next operator doesn't start from zero.
Education
The Fourth Utility
Electricity, water, gas — and compressed air. On many plasma systems the air is the cutting gas, so moisture, oil, and particles reach the arc. Our animated series explains why that matters and how to check your setup.
