HEAVY DUTY PORTABLE FLAME CUTTING MACHINE

Description:

Heavy duty portable flame cutting machines use oxy-fuel combustion to cut through thick ferrous metal plates and structural steel sections on-site, without requiring a fixed workshop setup. These machines bring industrial cutting capacity directly to construction sites, shipyards, military maintenance facilities, and field fabrication locations where moving large metal workpieces to a stationary machine is impractical.

Oxy-fuel flame cutting combines oxygen and a fuel gas — typically acetylene or propane — to generate a high-temperature cutting flame. The torch first preheats the metal to ignition temperature, then a high-pressure oxygen jet oxidizes and blows away the molten material to produce a clean cut kerf. Portable units handle cutting capacities from 5mm up to 300mm plate thickness depending on nozzle selection. Additionally, bevel cuts up to 90 degrees are possible on compatible torch configurations without repositioning the workpiece.

CNC-controlled portable variants mount on single-track or gantry rail systems that operators position directly on the metal plate. Stepper and servo motor drives provide smooth, consistent torch travel at programmable feed rates, eliminating the inconsistency of manual hand-held cutting. Furthermore, these units support DXF and G-code file input from AutoCAD and CAD/CAM software, allowing complex profile cuts and batch production runs without manual tracing. Arc voltage height control systems automatically maintain torch standoff distance during cuts. Plasma cutting heads integrate on dual-mode machines alongside the flame torch, covering non-ferrous metals including stainless steel, aluminum, and copper.

Power requirements vary between 220V single-phase and three-phase supplies. Internally asbestos-lined body construction and fiberglass-insulated circuits protect operators and components from heat exposure during extended operation.

These machines directly serve Pakistan’s shipbuilding facilities at Karachi, structural steel fabricators in Lahore and Faisalabad, Pakistan Army field engineering units, and heavy construction contractors working on infrastructure projects across Punjab and KPK.
