What is a Plasma Cutter?

A plasma cutter is a device that utilizes an accelerated jet of hot plasma to cut through various metals. Plasma consists of free electrons and ions, which makes it highly conductive.

A CNC plasma cutter is a computer-controlled cutting machine that controls the movement of the cutter based on pre-programmed designs.

CAD (Computer-Aided Design) software is used to design the parts, and CAM (Computer-Aided Manufacturing) software translates the design into machine instructions (G-code).

How does a Plasma Cutter Work?

1. Ionization:
  • An electric arc of a plasma cutter is made within the cutter, often between an electrode and conductive material being cut.
  • The cutter blows gas air, nitrogen, or oxygen through the nozzle at high speed.
  • When the gas passes through the electric arc, it ionizes, turning into plasma.
2.Cutting Process:
  • The plasma cutter reaches extremely high temperatures exceeding 20,000°C (36,000°F).
  • This hot and ionized gas melts the metal at the point of contact.
  • The high-velocity jet blows the molten metal away and cuts material easily.

Benefits of Using a Plasma Cutter

  1. Precision and Accuracy:
  2. Speed:
  3. Versatility:
  4. Cost-Effectiveness:
  5. Ease of Use:
  6. Easy to carry:

How to Buy the Best Plasma Cutter?

  • Identify Needs: Determine the types and thicknesses of materials you want to cut.
  • Power Requirements: Ensure compatibility with your power supply (110V, 220V, or both).
  • Cutting Capacity: Match the cutter’s capacity with the maximum metal thickness you need to cut.
  • Duty Cycle: A higher duty cycle is preferable for longer, continuous operations.
  • Brand and Quality: Choose reputable brands known for reliability and good support.
  • Features: Look for additional features like a pilot arc for non-contact cutting and CNC compatibility.
  • Budget: Compare prices and features to find the best value.

How to Check Before Buying?

  • Read Reviews:
  • Request Demonstrations:
  • Warranty and Support:
  • Verify Specifications:
  • Compare Models:
  • Expert Advice:
  • Inspect Build Quality:

How to Use a Plasma Cutter?

  • When you are using the plasma cutter first is Safety. Wear appropriate PPE like a welding helmet, gloves, protective clothing, safety glasses, and hearing protection. Ensure good ventilation and have a fire extinguisher nearby.
  • After the safety precaution, you can connect the plasma cutter to the power supply and air compressor.
  • Attach the ground clamp to a clean, bare metal surface on the workpiece.
  • Turn on the plasma cutter and adjust settings (amperage and air pressure) according to the material thickness.
  • Hold the torch perpendicular to the workpiece, close to the surface.
  • Press the trigger to start the arc.
  • Move the torch steadily along the cutting line, maintaining a consistent speed and distance.
  • Release the trigger to stop the arc when the cut is complete.
  • Allow the cutter and workpiece to cool down.
  • Inspect the cut and perform any necessary maintenance on the cutter.

My hand is not that steady but it cut nice and clean thru 10mm steel like butter. I was worried it wasn't the cnc version because the photos don't show the connectors but the seller assured me it was and now it has been delivered I can verify it definately is the cnc version. The photos show the brown version but as per the description it is the red one. Very happy with this purchase 😁 It comes with a 240v 15amp 3 pin Aussie plug and I ran it at full 55amps on a 'modified' 10amp socket and 20amp breaker, no problems.
