What Is a Portable CNC Flame Cutting Machine?
A Portable CNC Flame Cutting Machine is a computer-controlled thermal cutting system that uses an oxy-fuel flame-a combination of oxygen and a fuel gas like propane or acetylene-to cut through carbon steel. Unlike plasma cutting, which relies on an ionized gas arc, flame cutting works through a chemical reaction: the flame heats the steel to its ignition temperature, and a jet of high-purity oxygen (minimum 99.5%) causes the metal to oxidize and burn away along the programmed path. The machine reads standard DXF and DWG files, follows programmed paths, and delivers precision comparable to larger stationary gantry systems-but in a package light enough to move between job sites.
an important component
F2100B CNC system host (Shanghai Fangling)
As the core computing control unit of the cutting machine, it is responsible for reading the cutting drawing, planning the motion trajectory, and issuing the movement instructions. The key operation screen is integrated, providing intuitive and easy-to-use operation. It stably controls the X/Y axis operation of the entire machine and is compatible with various processing programs for plasma and flame cutting.
F1621 Plasma Arc Voltage Adjuster (Shanghai Fangling)
It continuously collects the arc voltage values, automatically adjusts the cutting torch height, compensates for the height deviations caused by the warping of the sheet and unevenness of the sheet surface. It precisely maintains a constant cutting nozzle distance, ensuring the quality of the piercing and cutting section, and significantly reducing the consumption of consumables.

Customer Cases
Ship Repair Yard, Turkey
A shipyard in Istanbul was cutting replacement plates for vessel repairs. The plates were typically 30mm to 80mm thick carbon steel-too thick for plasma to cut economically. Workers were cutting by hand with oxy-fuel torches. Quality varied between operators, and material waste was estimated at 20% of purchased plate.
They purchased a Portable CNC Flame Cutting Machine with a 1500×3000mm cutting area. The machine is positioned directly on the plate, cuts the required shapes, and moves to the next plate. No forklift or crane is required for material handling. Material utilization improved by approximately 25%, and cut quality is consistent across operators because the machine executes the same program every time. The workshop manager estimated the machine paid for itself within eight months through material savings alone.
Company Information and FAQs
Hebei Juliang Technology Co., Ltd. was founded in 2018 with a straightforward mission: build CNC cutting equipment that actually works in the conditions our customers face every day. Our 4,000-square-meter facility in Shijiazhuang is where we turn that mission into reality.
Our team designs machines for workshops that don't have unlimited budgets, for job sites where conditions are unpredictable, and for operators who need equipment that's straightforward to use and maintain. We've worked with steel fabricators, shipyards, heavy equipment manufacturers, and maintenance crews across more than 30 countries.
What thickness of carbon steel can a portable CNC flame cutting machine handle?
Flame cutting typically handles carbon steel from 5mm up to 200mm in a single pass. The exact thickness depends on the specific configuration, fuel gas type, and cutting speed. For materials over 100mm, slower speeds are required. This is the primary advantage of flame cutting over plasma for thick sections.
Can a portable CNC flame cutting machine cut stainless steel or aluminum?
No. Flame cutting relies on an oxidation reaction that only occurs in carbon steel. Stainless steel and aluminum don't oxidize in the same way, so the cutting oxygen jet won't sustain a cut. For these materials, you need plasma cutting. Some portable machines support both processes on a single gantry, allowing you to switch between them.
Why is oxygen purity important for flame cutting?
Oxygen purity of 99.5% or higher is required for consistent cut quality. Lower purity oxygen slows the oxidation reaction and produces a rough, irregular cut edge. This is one of the most common reasons for poor cut quality. If you're experiencing inconsistent cuts, checking oxygen purity is the first place to look.
How does setup time compare to a stationary flame cutting machine?
A portable machine sets up in 15 to 30 minutes from transport to first cut. A stationary machine is installed once and remains in place-setup is a one-time event. The portable machine trades permanent installation for the ability to move between locations. For a workshop that cuts thick plate regularly, a stationary machine might be more efficient. For on-site work or shops with limited space, the portable design is a clear advantage.
What's the difference between using propane and acetylene for flame cutting?
Acetylene provides a higher flame temperature (approximately 3,100°C) and faster preheat, making it suitable for thicker materials and faster piercing. It also provides a more concentrated heat. Propane has a lower flame temperature (approximately 2,800°C) but is more economical, more readily available in many regions, and produces a wider heat pattern that can be beneficial for certain applications. The choice depends on local availability, cost, and the specific cutting requirements.
