Portable plasma cutting uses a handheld plasma torch that can be easily carried to different locations for on-site cutting and repair work. It is widely used in construction, maintenance, automotive, and field operations where moving heavy materials to a cutting shop is not practical.

Specifications

  1. Cutting Thickness Range

    • Light-duty systems: up to 12mm (0.5”).

    • Medium-duty: up to 25mm (1”).

    • Heavy-duty portable units: up to 38mm (1.5”), depending on amperage.

  2. Cutting Current (Amperage)

    • Typically 20A – 100A for handheld units.

    • Compact but powerful enough for most on-site cutting needs.

  3. Cutting Speed

    • Very fast on thin sheets (can cut 5x faster than oxy-fuel).

    • Slower on thicker plates compared to CNC/HD plasma.

  4. Cutting Accuracy & Tolerance

    • Manual tolerance: approx. ±1.5mm – 3mm depending on operator skill.

    • Best for rough cuts, prep work, and general fabrication.

  5. Kerf Width (Cut Width)

    • 2mm – 4mm depending on torch nozzle size and plate thickness.

  6. Edge Quality

    • Produces more dross than CNC/HD plasma due to manual handling.

    • Usually requires minor grinding or finishing.

  7. Power Source

    • Portable units typically run on 110V, 220V, or generator power.

    • Some models are inverter-based for easy mobility.

  8. Compatible Materials

    • Mild Steel

    • Stainless Steel

    • Aluminum

    • Copper & Brass (limited)

Applications

  • On-site construction & steel structure work.

  • Automotive repair and bodywork.

  • Agricultural equipment & field repairs.

  • Pipe cutting, ductwork, and HVAC maintenance.

  • Remote locations without access to large cutting machines.
