Gantry CNC Plasma Cutting Machines
Gantry CNC plasma machines run on floor rails over the plate, so the cutting area is set by rail length and gantry width rather than by a table. PCL builds the G2040 (2000 × 4000 mm) and G3060 (3000 × 6000 mm) for 0.5–30 mm plasma and 6–150 mm oxy-fuel cutting, and a heavy-duty gantry 4 to 8 m wide for 6–100 mm plate with standard or HD plasma.

G2040 and G3060 gantries
The G2040 and G3060 are the standard gantries for 2 × 4 m and 3 × 6 m plate. The beam spans the plate on floor rails, the control sits on the end carriage, and the torch lifter carries a plasma torch with automatic torch height control. An oxy-fuel torch can be added for plate up to 150 mm.
For bevel cutting on plate, see the 3D bevel plasma cutting machine.
How a gantry machine is built
Plate-welded heavy frame
The beam and end carriages are welded from plate and stress-relief tempered, so the gantry stays rigid at full torch speed.
Dual-drive synchronization
A motor on each rail drives the gantry, and the two are synchronized so the beam stays square over the full cutting bed.
Linear guides and rack
Precision linear guide rails and high-accuracy rack-and-pinion drives give fast response on short moves and accurate long cuts.
Multi-process
Plasma for fast, clean cuts up to 30 mm or 100 mm, plus oxy-fuel torches for plate beyond plasma range.
HD plasma option
On the heavy-duty gantry, high-definition plasma gives squarer edges with little dross, often ready for welding.
Separate cutting table
The plate sits on a water or slat table between the rails, so you can load one zone while the machine cuts another.

| Your plate | Suggested machine |
|---|---|
| Up to 2000 × 4000 mm, under 30 mm | G2040 |
| Up to 3000 × 6000 mm, under 30 mm | G3060 |
| Wider than 3 m, or regularly over 30 mm | Heavy-duty gantry, 4–8 m |
| Beyond plasma range (over 100 mm) | Any gantry with oxy-fuel torches |
Plasma current and thickness
Swipe the table sideways to see all columns.
| Plasma current | Good-quality cut (edge start) | Production pierce | Typical work |
|---|---|---|---|
| 85 A | up to 20–25 mm | about 12–16 mm | Brackets, base plates |
| 100–105 A | up to 25–32 mm | about 16–20 mm | Fabrication shops |
| 120–125 A | up to 32–38 mm | about 20–25 mm | Thicker structural plate |
| 200 A | up to 50 mm | about 30–32 mm | Heavy plate on gantries |
| 300 A | up to 60 mm | about 40 mm | Heavy fabrication |
| 400 A | up to 80 mm | about 50 mm | Very heavy plate, large pipe |
Typical guidance for mild steel. Stainless steel and aluminum cut thinner. Capacity differs between plasma brands, so we confirm it for the source on your quotation. CNC parts usually start with a pierce, which is roughly half to two thirds of the edge-start thickness.
Typical work
Shipbuilding
Hull plates, frames and brackets from large plate.
Construction machinery
Booms, buckets and chassis parts in thick wear plate.
Steel structures
Base plates, gussets, splice plates and stiffeners.
Pressure vessels and tanks
Heads, flanges and large rings.
What your workshop needs
- Electrical supply: 3-phase industrial supply sized to the plasma source; oxygen and fuel gas for oxy-fuel torches. Tell us your local voltage and frequency (50 or 60 Hz) before we build the machine.
- Clean, dry compressed air: an air compressor with a refrigerated dryer and filters. We give the flow and pressure for the plasma source you choose.
- A level concrete floor and space to load full sheets with a forklift or crane.
- Fume control: a water table or a down-draft table with an extraction fan, depending on the model.
- A Windows PC for nesting software such as FastCAM, to turn DXF drawings into cutting programs.
Shipping, installation and support
Free production layout
Send your parts list or shop drawing and our engineers suggest the machine size, plasma source and table layout before you order.
Packed for sea freight
Machines are packed for container shipping. We quote to your nearest port in South America, Africa or elsewhere and prepare the export documents.
Installation and training
Remote installation guidance and operator training are included. On-site commissioning can be arranged.
Remote diagnostics
Our team supports the control, the plasma source and the nesting software remotely, so most problems are solved without waiting for a visit.
Get a configuration and price
Send the material, the thickest plate or largest pipe you cut, your sheet or pipe size and how many hours a day the machine will run. An engineer replies with the right gantry size and plasma source, the options and a price delivered to your port.
Frequently asked questions
What gantry widths are available?
The G2040 cuts 2000 × 4000 mm and the G3060 cuts 3000 × 6000 mm. The heavy-duty gantry is built 4 to 8 m wide, with rail length to suit your plate.
Is accuracy held across the whole width?
Yes. Dual synchronized drives keep the beam square; the heavy-duty gantry holds ±0.05 mm repositioning across the full working width.
How thick can a gantry machine cut?
The G2040 and G3060 cut 0.5–30 mm with plasma and 6–150 mm with oxy-fuel. The heavy-duty gantry cuts 6–100 mm with plasma, more with oxy-fuel.
Which plasma sources can be fitted?
Hypertherm, LGK, Thermadyne or Kjellberg on the heavy-duty gantry, and Hypertherm or Chinese brands from 65 A to 200 A on the G2040 and G3060.
Can I fit more than one torch?
Yes. A gantry can carry plasma and oxy-fuel torches together, and extra oxy-fuel torches for cutting identical parts at the same time.
