Rotary Triple-Torch Oxy-Fuel
Triple-Torch Rotary Flame Cutting Machine
On thick plate, cutting speed is not the limit — torch time is. This machine puts a rotary three-torch head on one CNC gantry so three identical profiles come off the table in the time one used to take, and the same head tilts to cut V, X, Y and K weld preparations while it profiles.

The Case for a Torch Group
Three Torches Collapse the Cycle on Heavy Plate
Flame cutting is slow by nature: the thicker the plate, the longer each metre of cut takes. Adding torches is the only way to raise throughput without compromising the cut, because each torch still runs at the correct speed for the thickness.
- Matched multi-torch cuttingThe group runs three profiles at once, so output rises without pushing a single torch past its correct cutting speed.
- Rotary headThe torch head rotates and tilts to switch between square cuts and angled weld preparations on the same path.
- Automatic gas consolePressure and flow are managed per torch, which is what keeps three flames identical across a long run.
- Modular optionsEdge inspection, marking and gas control can be specified to suit the job rather than bought as a fixed package.
Technical Data
Configuration of the Triple-Torch Platform
This platform is built around a rotary torch group. Table size, track length, torch spacing and option set are confirmed on the build sheet for each order.
| Parameter | Specification |
|---|---|
| Cutting process | Oxy-fuel flame cutting |
| Torch configuration | Rotary triple cutting torch, group mounted on one carriage |
| Bevel capability | Angled weld preparations produced by torch rotation and tilt |
| Automatic gas console | Optional — manages pressure and flow per torch |
| Automatic edge inspection | Optional |
| Marking function | Optional |
| Control system | CNC cutting control with process parameter library |
| Drive and gantry | Motorized gantry with track, sized to the cutting table |
| Materials | Carbon steel and thick plate |
| Typical thickness band | Heavy plate, roughly 20–300 mm (process guidance, not a fixed machine limit) |
| Table size | Built to order |
| Torch spacing | Set to the nesting and part family at order |
The source datasheet for this platform lists the rotary triple torch and the optional modules rather than a fixed parameter list. Table size, track length, torch spacing, gas set and option combination are therefore confirmed against your drawing before production. Thickness bands are typical process guidance and are verified with a test cut on your plate.
Core Strengths
Built for Thick Plate and Long Runs
Four things this machine does that a single-torch flame table cannot.
Three-Torch Output
Three matched profiles per pass. Throughput scales with torch count while every flame stays at its correct cutting speed.
Rotary Bevel Head
The head rotates and tilts so V, X, Y and K weld preparations are cut in the same pass as the outline.
Consistent Gas Control
An automatic gas console holds pressure and flow steady, which is what keeps three flames running identical edge quality.
Modular Build
Edge inspection, marking and gas control are chosen per order, so the machine carries what the job needs and nothing it does not.

Oxy-fuelprocessNo plasma source required
No Plasma Consumables
Oxy-fuel cutting runs on gas and a nozzle rather than electrodes and shields, which simplifies the running cost on heavy carbon plate.
Square, Strong Edges
A flame-cut edge is square and mechanically sound. It carries a wider heat-affected zone, so the edge is normally machined before a critical weld.
One Controlled Group
The three torches travel as a single carriage, so spacing and alignment are set once and repeated on every plate in the nesting.
Rotary Head & Bevel Geometry
How Torch Rotation Turns a Profile into a Weld Prep
A square torch cuts a square edge. Rotate and tilt the head and the same nozzle cuts an angled face — the four standard weld preparations come from that single movement.
V
V Bevel
Both plates receive an angled face so the joint closes into a V. The most common single-sided weld preparation on medium to thick plate.
X
X Bevel
Angled faces on both sides of the plate. Used where the weld is made from both sides and full penetration is required.
Y
Y Bevel
A vertical land with an angled top face. It controls the root gap and suits heavy sections where a deep narrow weld is wanted.
K
K Bevel
A double-sided Y form. It gives a symmetrical weld preparation on thick plate that is welded from both faces.
Operating Cycle
From Nesting File to Cut Plate
The torch group changes the output, not the routine. The workflow stays the same as any CNC flame table.
01
Nest the Plate
Import the part outlines and set the nesting, including torch spacing for the three-torch group and any bevel geometry.
02
Set the Process
Choose the plate type and thickness so the control system selects the cutting parameters, gas pressures and cutting speed.
03
Cut with Three Torches
The gantry drives the group along the path while all three flames cut matched profiles at the same controlled speed.
04
Mark and Release
If the marking option is fitted, part identification is applied before the plate is unloaded and the next nesting begins.
Where It Earns Its Place
Heavy Plate, Repeated Parts
The triple-torch layout pays back fastest when the same heavy outlines repeat plate after plate.
Structural Fabrication
Base plates, gussets and stiffeners cut in matched sets, with bevels prepared for full-penetration welds.
Heavy Equipment Builds
Machine bases and frames cut from thick carbon plate, where the wide flame kerf and square edge suit the following machining step.
Plate Processing Shops
Nesting-driven cutting where the same heavy outlines repeat daily and the torch group multiplies throughput.

FAQ
Triple-Torch Rotary Flame Cutting Questions
Oxy-fuel flame cutting is the heavy-plate process. As a rule it starts to make sense from about 20 mm and is the only practical route beyond roughly 100 mm, where plasma sources no longer reach. The triple-torch build is aimed at that heavy range in volume. Send the plate grade and thickness band and we confirm nozzle, gas set and cutting speed for your work.
The rotary torch head tilts and rotates the nozzles so the cut edge can be angled rather than square. That produces standard weld preparations such as V, X, Y and K edges in the same pass as the profile, on both straight and curved paths, removing a separate grinding or machining operation.
A three-torch group is set up so the torches cut a matched set of profiles in one pass, which is how the machine multiplies output on thick plate. Torch spacing is set to the nesting and the plate layout, and the group can be configured for the part family you run most. Tell us the outline and batch pattern and we propose the spacing.
Four options are offered on this platform: automatic edge inspection, an automatic gas console, a marking function and the rotary triple cutting torch itself. They can be specified together or added according to the job, and are confirmed on the build sheet before production starts.
Oxy-fuel cutting uses oxygen with a fuel gas such as propane, natural gas or acetylene. The automatic gas console manages pressure and flow, and the exact mix and regulator set are matched to your plate and to the gas available on site, then confirmed before shipment.
A standard triple-torch gantry ships in roughly 30 to 45 working days, with table size, track length and option set adding to that. The machine is assembled, aligned and test cut before packing, and we provide English manuals, drawings, remote video commissioning and lifetime technical support.
