Plasma Cutting Systems

Plasma cutting systems sever electrically conductive metals including steel, stainless steel, aluminum, copper, and brass by directing a high-temperature ionized gas jet through the material at cutting speeds significantly faster than mechanical cutting methods. These systems find application across metal fabrication shops, vehicle recovery operations, construction sites, military engineering units, and emergency rescue scenarios where rapid metal severance of varying material thickness is required in field or workshop environments across Pakistan.

The cutting process ionizes a gas stream, typically compressed air, nitrogen, or argon-hydrogen mix, by passing it through an electric arc struck between the torch electrode and the workpiece. Arc temperatures reach between 20,000 and 30,000 degrees Celsius within the plasma column, melting the base metal while the high-velocity gas jet expels the molten material downward through the kerf. Cutting speeds on 6mm mild steel plate run between 1000 and 3000mm per minute depending on amperage setting and torch standoff distance, significantly outpacing oxy-fuel cutting at equivalent material thickness. Additionally, cut quality on plasma systems produces a narrow kerf width between 1.5 and 3mm with minimal heat-affected zone width compared to oxy-fuel methods, reducing post-cut grinding requirements on precision fabrication work.

Power supply units use inverter-based technology operating on single-phase 220V or three-phase 380V AC input, with output amperage ranging from 20A on compact portable units up to 200A or higher on heavy industrial systems. Cutting capacity scales with amperage, with 40A systems handling up to 12mm steel and 100A systems cutting through 25mm steel plate at production speeds. Furthermore, pilot arc ignition on current plasma systems starts the cutting arc without requiring contact between the torch tip and the workpiece, extending consumable life and allowing cutting through painted, rusty, and expanded metal surfaces without arc establishment difficulty.

Torch consumables include the electrode, swirl ring, nozzle, and shield cap, with replacement intervals dependent on cutting duty cycle and material type. Moreover, portable plasma cutting systems with integrated air compressors weigh between 15 and 30 kilograms, supporting vehicle-mounted deployment for military engineering and emergency rescue operations across remote locations in Pakistan.

Tactical Supply Pakistan supplies plasma cutting systems to metal fabrication workshops, military engineering units, construction contractors, vehicle recovery operators, and emergency rescue services requiring fast, portable metal cutting capability across field and workshop environments throughout Pakistan.
