5. Configuració
Follow these steps to set up your plasma cutter for operation:
- Connexió d'alimentació: Connect the plasma cutter to a suitable power source. The machine supports 110V or 220V. Use the provided adapter cord for 110V connections if necessary.
- Connexió aèria: The unit features a built-in air regulator. Connect your air compressor hose to the pre-assembled air connector on the rear panel. Secure it with a hose band. Ensure your air compressor provides clean, dry air at the recommended pressure (typically 85 PSI for optimal cutting).
- Terra Clamp Connexió: Enganxa el terra clamp cable to the designated connector on the front panel. Securely attach the ground clamp a la peça de treball o a la taula de treball, garantint un bon contacte elèctric.
- Cutting Torch Connection: Connect the cutting torch cable to the torch connector on the front panel.
- Encès: Flip the power switch on the rear panel to the 'ON' position. The LED display will illuminate.

6. Instruccions de funcionament
6.1. Non-Touch Pilot Arc
The AZZUNO CUT-55L features a 55A high-frequency, non-touch pilot arc. This technology allows the arc to ignite without direct contact with the metal, reducing consumable wear and providing cleaner, more precise cuts on painted, rusted, or uneven surfaces.

6.2. Cutting Capacity
The machine offers powerful plasma cuts with precision. Optimal cutting capacity depends on the input voltage:
- Tall net:
- 3/8" (10 mm) @ 110V
- 5/8" (16 mm) @ 220V
- Max Cut:
- 1/2" (12 mm) @ 110V
- 3/4" (20 mm) @ 220V
It is capable of cutting various metals including mild steel, stainless steel, aluminum, and copper. It effectively handles solid plate, expanded metal, and perforated mesh.

6.3. Multiple Cutting Modes
The plasma cutter includes several settings for precise control:
- TEST AIR: Allows checking airflow without igniting the arc.
- PRE-FLOW: Controls the gas delay (0.1-1s) before arc ignition for smoother starts.
- POST-FLOW: Sets the cooling time (1-10s) after cutting to protect the torch and consumables.
- 2T/4T Settings:
- 2T (2-Stroke): Press and hold the torch trigger to cut. Release to stop. Ideal for short cuts.
- 4T (4-Stroke): Press the trigger once to start cutting, release to continue cutting without holding. Press again to stop. Ideal for longer cuts and reduced finger fatigue.
6.4. Air Sensor Technology
A built-in pressure monitoring system with a warning light alerts you if the air pressure is outside the optimal range (Low, Normal, High). This ensures consistent performance and helps prevent machine damage.

7. Manteniment
Regular maintenance ensures the longevity and optimal performance of your plasma cutter:
- Consumibles: Regularly inspect the torch tip and electrode for wear. Replace them when they show signs of degradation to maintain cut quality.
- Filtre d'aire: Check and clean the air filter periodically to ensure a clean and dry air supply. Replace if damaged.
- Neteja: Keep the machine clean and free from dust and metal particles. Use compressed air to blow out internal components if necessary, ensuring the machine is unplugged.
- Cables i connexions: Inspect all cables and connections for damage or loose fittings before each use.
