CIRCO Series Circle Cutting Machine
Perfect circles. Clean flanges. Zero freehand guesswork.
Cutting a true circle in thick MS plate with a freehand torch is one of the toughest jobs in any fabrication shop. The line wanders, the kerf widens, and the grinder runs for hours afterwards. The CRUXWELD CIRCO series circle cutting machine solves this problem permanently. Set the radius, ignite the torch, engage the drive — and the machine cuts a near-perfect circle, flange, or hole in mild steel plate from Ø30 – 1000 mm with cutting accuracy better than 1 mm per revolution.
Available in two models — CIRCO-600 (circles up to Ø600 mm) and CIRCO-1000 (circles up to Ø1000 mm) — this is the machine that turns your most frustrating cutting job into your fastest one.
The CIRCO series is a portable, semi-automatic circular gas cutting machine that works on the oxy-fuel cutting process. The working principle is beautifully simple: a centre pin locates the machine on your plate, a graduated radius bar sets the exact circle diameter, and a motorized drive rotates the cutting torch smoothly around the centre. The result is a clean, round cut that needs little or no finishing.
Unlike a hand-guided compass attachment, the CIRCO’s DC motor drive with stepless speed control keeps the torch moving at a perfectly constant speed — the single biggest factor in cut quality. A 360° rotating gas distributor means the oxygen and fuel hoses never twist, no matter how many circles you cut in a shift. And because the entire machine runs on ordinary 220V single-phase power and standard workshop gases, it fits into any fabrication setup — from a small flange manufacturing unit to a heavy vessel shop.
The CIRCO series joins our complete range of gas cutting machines engineered and supported by Cruxweld across India.
Every workshop that cuts flanges, manholes, or round blanks faces the same three enemies: wavy edges, wasted gas, and rework time. Here is how the CIRCO series eliminates all three.
🎯 No More Wavy Circles
The radius bar locks the diameter and the motor locks the speed. Every circle comes out round, every time — whether it is your first cut of the day or your fiftieth.
⛽ Lower Gas & Grinding Cost
A constant torch speed produces a narrow, clean kerf. That means less oxygen burned per cut and dramatically less grinding on the finished edge — savings you see every month.
🏭 Any Shop, Any Site
Compact, portable, and powered by 220V single phase with LPG or acetylene — the CIRCO works in a fabrication shop, at a project site, or right beside the vessel you are building.
🔧 One Machine, Three Jobs
Cut outer circles for blanks, inner circles for flanges, and round holes for nozzles — plus bevel edges from 0–45° for weld preparation, all with the same machine.
Motorized Stepless Speed Drive
DC permanent-magnet motor with worm-gear reduction gives smooth torch rotation from 0.2 to 6 rpm — dial in the exact speed for any plate thickness.
Heavy Cast Aluminium Body
High-strength cast aluminium alloy construction keeps the machine rigid for accuracy yet light enough for one or two people to shift and position.
360° Rotating Gas Distributor
The gas manifold rotates freely with the torch, so hoses never wrap or twist — cut continuous circles without stopping to untangle lines.
0–45° Bevel Cutting
Tilt the torch to cut weld-ready bevelled edges on flanges and openings — finish the cut and the weld prep in a single operation.
LPG & Acetylene Compatible
Ships with 3 propane/LPG cutting nozzles covering the full thickness range; acetylene nozzle sets are available on request for shops running DA gas.
<1 mm Cutting Accuracy
Deviation of less than 1 mm per revolution means flanges drop into position and machining allowances can be kept to a minimum.
Retractable Centre Pin
The centre point retracts so even small-diameter circles can be cut cleanly without damaging or wasting the central blank.
Quick Positioning & Clutch Control
Roller wheels on the base and a simple clutch handle let the operator position the machine, engage the drive, and start cutting in seconds.
Both models share the same drive, body, torch, and cutting quality. The only real difference is reach — the maximum circle diameter the radius bar allows.
CIRCO-600
Cutting range: Ø30 – 600 mm
The right choice for flange manufacturers, pipe fabricators, and general job shops where most circles, flanges, and nozzle holes fall under 600 mm. Lighter and easier to move around the shop.
CIRCO-1000
Cutting range: Ø30 – 1000 mm
Built for tank and pressure vessel shops, boiler manufacturers, and heavy fabricators cutting large manholes, dished-end openings, and big-diameter blanks up to one metre.
Quick rule: if your largest regular circle is under 600 mm, take the CIRCO-600. If you handle vessels, tanks, or large flanges, the CIRCO-1000 pays for itself on the first big job.

Every CIRCO machine is supplied with three LPG/propane cutting nozzles (sizes 1, 2, and 3) that together cover the practical plate range most fabrication shops cut daily. Since LPG is the most economical and widely available fuel gas in Indian workshops, the standard nozzle set keeps your running cost low from day one. For shops that operate on dissolved acetylene, matching acetylene nozzle sets are available — simply mention your gas setup while placing the enquiry and we will supply the machine ready for your line.
Correct nozzle selection and steady rotation speed are what give the CIRCO its clean, square-edged cuts — the machine controls the speed, and our team will guide you on nozzle-to-thickness selection during installation.
1. Position & Centre
Roll the machine over the plate and locate the centre pin on your marked centre point.
2. Set the Radius
Slide the torch holder along the radius bar to the required circle radius and lock it.
3. Ignite & Set Speed
Light the torch, preheat the start point, and dial the rotation speed to suit the plate thickness.
4. Engage & Cut
Engage the clutch — the motor takes over and the torch travels a perfect circle to completion.
The CIRCO circle cutting machine earns its place anywhere round components are cut from steel plate:
Many of our customers pair the CIRCO with the TUBOCUT-HG manual pipe gas cutting machine — CIRCO handles the plate circles and flanges, TUBOCUT handles the pipe cutting and beveling, and together they cover the complete fit-up. For high-volume pipe work, our automatic pipe cutting machine completes the line.
Your CIRCO machine arrives ready to work: machine body with motorized drive, radius bar, cutting torch, 3 LPG/propane cutting nozzles (No. 1, 2, 3), power cable, gas hose connector set, spare fuses, nozzle tip cleaner, and the operation manual with warranty card. Standard scope of supply — confirm the final packing list with our team at the time of order.

Both models share the same body, motorized drive, torch, and cutting quality. The only difference is the maximum cutting circle diameter — the CIRCO-600 cuts circles from 30 to 600 mm, while the CIRCO-1000 cuts from 30 to 1000 mm using a longer radius bar.
The CIRCO series cuts mild steel plate from 6 mm up to 100 mm thickness using the oxy-fuel process. The correct nozzle size and rotation speed are selected according to the plate thickness for the cleanest cut edge.
The machine is supplied as standard with 3 LPG/propane cutting nozzles, since LPG is the most economical fuel gas for Indian workshops. Acetylene nozzle sets are available on request, so the machine can run on whichever gas line your shop already uses, along with cutting-grade oxygen.
Yes. Cut the outer diameter first, then reset the radius bar and cut the inner diameter from the same centre point. Because both cuts share one centre, the flange comes out perfectly concentric — ideal for flange manufacturing.
Yes. The CIRCO series runs on ordinary 220V single-phase, 50 Hz supply. The low-power DC drive motor consumes very little electricity, so no special power arrangement is needed — any workshop plug point will do.
Yes. The torch holder tilts from 0° to 45°, so you can cut a bevelled edge on the circle in the same pass — the opening or flange comes off the machine already prepared for welding.
