AirForce™ 40i Plasma Cutter

With Auto-Refire™ Technology for Expanded Metal Applications

Need to cut steel? Thinking about an oxy acetylene cutting torch to do the job? Consider a plasma cutter. This simple technology uses an electrical arc and compressed air to cut steel, aluminum, and other conductive metals.

The AirForce™ 40i is an economical plasma cutting system for all conductive metals. Inverter-based design and reliable technology pack a lot of performance into a very portable package. The Airforce™ 40i plasma cutting system is excellent for light and heavy industrial users. Automated operations are also well within its range. Unit is compatible with engine-driven welders when powered with a 240 V generator power outlet of 8 kW or more.

Compared to the complexities of an oxy fuel cutting torch system, plasma cutting is easy:

Comes complete with:
  • XT40R torch with 12 ft (3.66 m) lead and consumables
  • Heavy-duty work clamp with cable
  • 10 ft. (3 m) power cord with 230 VAC, 50 A plug
Input Power:
  • 208-240 VAC, 50 amp circuit, single phase

  • Inverter Design - Powerful cutting ability at just over half the weight of prior model (AirForce 625). Weighs only 31.4 lbs.
  • Auto-Refire™ Technology - Allows operator to cut expanded/perforated metals, as well as painted or coated surfaces, without continuously retriggering the torch.
  • Capable with Engine-Driven Welders - Capable of cutting 3/8 to 5/8 in. mild steel when powered by an engine-driven welder with a 240 V generator power outlet of 8 kW or more.
  • New High-Performance Ergonomic Torch - The new XT40R torch is designed for increased comfort, more efficient cooling and longer lasting cutting tips.
  • Post-flow Air Cooling - Cools the torch and tip after cutting, extending life of replaceable tip and electrode.
  • Fan-On-Demand - Runs only when needed reducing dust/debris pulled into unit.
  • Wind Tunnel Technology - Prevents abrasive dust and particles from damaging internal components.
  • Thermal Overload Protection - Built to withstand tough working environments. Rated for 35% duty cycle at 104° Fahrenheit. Duty cycle will increase as environmental temperature decreases.
  • Line Voltage Compensation (LVC) - Provides peak performance power under variable input voltage conditions (±15%) for steady and cleaner ending cuts.
  • Power Factor Correction - Expands operator’s work area via extension cords while minimizing nuisance trips caused by voltage drops.
