3. Setup Instructions
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage during transit.
- Power Connection: Connect the plasma cutter to a suitable 240V power supply. Ensure the power outlet is properly grounded and rated for the machine's current draw.
- Air Compressor Connection:
- Attach the air filter to the designated air inlet on the plasma cutter.
- Connect the gas hose from the air filter to your air compressor. Ensure all connections are secure and leak-free.
- Set the air compressor output pressure according to the recommended settings for your cutting application (refer to the "Operating Instructions" section). The air sensor technology will assist in maintaining optimal flow.
- Torch and Ground Clamp Connection:
- Connect the AG60 cutting torch to the front panel of the plasma cutter. Ensure it is securely fastened.
- Connect the ground clamp cable to the designated terminal on the plasma cutter.
- Attach the ground clamp firmly to the workpiece or work table, ensuring good electrical contact.
- Initial Check: Before powering on, double-check all connections and ensure the work area is clear and safe.
4. Operating Instructions
Follow these steps for safe and effective operation of your Haxiaoer HXC550D Plasma Cutter.
4.1 Powering On and Display Overview

- Turn on the main power switch on the plasma cutter.
- The LED display will illuminate, showing current settings for voltage, current (Amps), and air pressure.
- Adjust the current (Amps) using the control knob on the front panel according to the material thickness and type. The display provides real-time feedback.
4.2 Non-Touch Pilot Arc Operation

- The non-touch pilot arc allows you to start cutting without direct contact between the torch tip and the workpiece.
- This feature is particularly useful for cutting painted, rusted, or uneven surfaces, as it eliminates the need for surface preparation.
- Simply position the torch approximately 1-2mm above the workpiece and press the trigger to initiate the pilot arc.
4.3 2T/4T Cutting Function

- 2T (Two-Touch) Mode: Press and hold the torch trigger to start cutting. Release the trigger to stop cutting. This mode is suitable for short cuts.
- 4T (Four-Touch) Mode: Press and release the torch trigger to start cutting. The arc will remain active. Press and release the trigger again to stop cutting. This mode is ideal for long cuts, reducing hand fatigue.
- Select the desired mode using the 2T/4T switch on the control panel.
4.4 Cutting Procedure

- Ensure the workpiece is clean and the ground clamp is securely attached.
- Adjust the cutting current (Amps) based on the material type and thickness.
- Position the torch tip correctly (1-2mm above for non-touch pilot arc).
- Press the torch trigger to initiate the arc. Move the torch steadily along the desired cut line. Maintain a consistent travel speed for a clean cut.
- Observe the cut quality. Adjust current or travel speed as needed.
- After cutting, the machine will engage a post-flow of gas for 2-15 seconds to cool the torch and extend its lifespan.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your plasma cutter.
5.1 Daily Maintenance:
- Inspect the torch consumables (electrode, nozzle, shield cup) for wear and replace if necessary.
- Check the ground clamp and cables for damage or loose connections.
- Empty any water from the air filter/regulator bowl.
- Clean the exterior of the machine to prevent dust and debris buildup.
5.2 Periodic Maintenance:
- Inspect the internal components for dust accumulation. Use compressed air to gently clean the interior if needed (ensure power is disconnected).
- Check all electrical connections for tightness.
- Examine the gas hose for cracks or leaks.
Note: Always disconnect the power supply before performing any maintenance procedures.
