CNC Plasma Cutter

Manufacturer:  A2 MechShop, HyperTherm
Model:  CNC Plasma Cutter Gantry, Model 45 Plasma Cutter

Maker Works’ CNC plasma cutter combines the cutting abilities of a HyperTherm 45 plasma cutter with a precision CNC gantry system built at the A2 MechShop.  It can cut intricate shapes out of sheet metal from very thin gauges to over 1/2″ thick.  Hardness of material does not matter.  LinuxCNC is used as the CNC control software, and a hardware torch height controller continuously monitors torch height.  Use SheetCam to convert DXF files (generated by Inkscape, AutoCAD, CorelDraw, Adobe Illustrator, etc.) for use on the CNC plasma cutter.


Plasma Cutter Modified HyperTherm 45
Maximum thickness 3/4″ (1/2″ recommended)
Maximum speed 380 inch/minute
Kerf width 0.030″ to 0.060″ (depends on materials, etc.)
100% duty cycle 32A
50% duty cycle 45A (10 minute interval)
Cutting area greater than 48″ x 48″


  • Fast
  • Cuts without regard to hardness of material
  • Cuts any conductive material
  • Minimum heat-affected zone (HAZ)
  • Edges often require minimum clean-up


No hazardous materials–e.g., galvanized steel, zinc-plated.

Projects with many start/stops will increase wear on the consumable tip.


Sheet metal up to 1/2″ (or thicker, with care).
