27-Amp Plasma Cutting
The AirForce 27i provides up to 27 amps of plasma-cutting output, making it a practical option for many everyday metal-cutting tasks.
Plasma cutting uses an electrical arc and a high-velocity gas stream to melt and remove metal. Because the plasma torch does not require a mechanical cutting blade, it can follow straight, curved, and irregular cut paths with appropriate operator technique.
Cutting performance depends on material type, thickness, amperage, travel speed, air quality, consumable condition, and electrical supply.
Integrated Air Compressor
A major convenience of the AirForce 27i is its built-in air-compressor system. This reduces the need to transport and connect a separate compressor for compatible cutting applications.
An integrated air source is particularly useful for:
Mobile repair work
Small workshops
Maintenance operations
Garage projects
Construction sites
Locations where an external compressor is inconvenient
The air system should be maintained according to Hobart's recommendations to help preserve cutting performance and consumable life.
Plasma Cutting Process
Plasma cutting is designed for electrically conductive materials. The machine generates a concentrated plasma arc that melts the workpiece while the gas stream removes the molten material from the cut.
Compared with many conventional cutting techniques, plasma cutting can offer:
Fast cutting speeds
Narrow kerf width
Minimal mechanical contact
Easy cutting of irregular shapes
Convenient piercing of suitable materials
Reduced physical effort compared with manual sawing
The appropriate travel speed and amperage depend on the material being cut.
Compatible Materials
The AirForce 27i can be used for cutting suitable electrically conductive metals, including:
Mild steel
Stainless steel
Aluminum
Other compatible conductive metals
The maximum practical thickness depends on the specific material, machine settings, cutting speed, and the manufacturer's published cutting specifications.
For heavier material, a slower and more controlled travel speed may be necessary. For thinner sheet metal, lower output settings can help reduce unnecessary heat input.
Pilot-Arc Operation
Pilot-arc technology helps initiate the plasma arc without requiring the cutting torch to remain in direct contact with the workpiece.
This can be useful when working with:
Expanded metal
Perforated sheet
Rough or irregular surfaces
Painted or coated surfaces, where appropriate preparation is possible
Maintaining the correct torch position and travel speed remains important for producing a clean cut.
Cutting Quality
Good plasma-cutting results depend on more than amperage alone. Important factors include:
Material thickness
Metal type
Cutting amperage
Torch height
Travel speed
Air quality
Consumable condition
Workpiece cleanliness
Moving too slowly can produce excessive slag and a wider kerf, while moving too quickly can prevent complete penetration. Proper technique and correct machine settings help produce cleaner, more consistent cuts.
Typical Applications
The Hobart AirForce 27i is suitable for:
Automotive repair
Sheet-metal work
General fabrication
Equipment maintenance
Farm equipment repair
Construction work
Garage projects
Custom metal fabrication
HVAC-related metal cutting
General workshop cutting
Benefits
27A maximum output provides useful capacity for light- and medium-duty metal cutting.
Integrated air compressor simplifies equipment setup.
Inverter technology contributes to a compact, portable design.
Pilot-arc operation makes cutting irregular and perforated material more convenient.
Multi-metal capability supports compatible steel, stainless steel, aluminum, and other conductive metals.
Portable format makes it practical for both workshop and field applications.
Blade-free cutting process allows operators to create straight, curved, and detailed cuts.
Torch Consumables
Plasma-cutting performance depends heavily on the condition of the torch consumables. Components such as the electrode and cutting tip naturally wear during operation.
Inspect consumables regularly for:
Excessive electrode wear
Damaged or enlarged nozzle openings
Pitting
Cracking
Irregular arc behavior
Reduced cutting performance
Replace worn consumables according to Hobart's recommended service procedures.
Air Quality
Clean, dry air is important for maintaining plasma-cutting performance. Moisture, oil, and contaminants can negatively affect the arc and reduce consumable life.
The integrated compressor and air system should be maintained according to the manufacturer's recommendations. Keep ventilation openings clear and ensure the machine has adequate airflow during operation.
Cutting Setup
Before starting:
Inspect the torch and consumables.
Verify the electrical supply is suitable.
Ensure the integrated air system is ready.
Connect the work clamp securely to clean conductive metal.
Select an appropriate cutting amperage.
Mark the intended cutting path.
Position the torch correctly.
Start the arc and maintain a consistent travel speed.
Inspect the cut and adjust the technique if necessary.
For important workpieces, make a test cut on scrap material first.
Maintenance
Regular maintenance helps keep the AirForce 27i operating reliably. Inspect the torch, consumables, work lead, electrical connections, and ventilation openings periodically.
Keep the machine clean and free from excessive dust and debris. Check the air system as recommended by Hobart, and replace worn torch components when cutting performance begins to deteriorate.
Safety Information
Plasma cutting produces intense heat, ultraviolet radiation, sparks, molten metal, fumes, and electrical hazards. Operators should wear an appropriate plasma-cutting helmet or face protection, welding gloves, flame-resistant clothing, safety footwear, and other required PPE.
Use adequate ventilation or fume extraction, particularly when cutting painted, coated, galvanized, or contaminated materials. Keep combustible materials away from the cutting area and establish suitable fire-prevention measures.
Never operate the plasma cutter outside the environmental, electrical, or operating conditions specified by the manufacturer.
Who Is It For?
The Hobart AirForce 27i Plasma Cutter is a practical choice for mechanics, fabricators, maintenance technicians, contractors, farmers, and serious DIY users who need a portable plasma-cutting system for everyday metalwork. Its combination of 27-amp output, integrated air supply, inverter technology, and multi-metal cutting capability makes it well suited to repair, fabrication, and maintenance applications.
Always consult the current Hobart owner's manual and official product documentation for exact electrical requirements, cutting and severance capacities, duty-cycle ratings, air specifications, consumable part numbers, dimensions, weight, and operating limitations.
