2. Safety Information

WARNING: Plasma cutting can be dangerous. Always follow safety precautions to prevent serious injury or death.

• Eye and Face Protection: Always wear a welding helmet with appropriate shade filter and safety glasses with side shields.
• Body Protection: Wear flame-resistant clothing, heavy-duty gloves, and protective footwear.
• Fume Hazards: Ensure adequate ventilation to remove fumes and gases. Do not cut in confined spaces.
• Electrical Shock: Ensure the machine is properly grounded. Do not operate in wet conditions. Inspect cables for damage before use.
• Fire and Explosions: Keep flammable materials away from the cutting area. Sparks and hot metal can cause fires.
• Noise: Wear hearing protection during operation.
• CE Certification: This product is CE certified, indicating compliance with European safety standards.

3. Product Features

• Powerful Cutting Performance: Capable of 1/2 inch (12.7mm) ideal clean cutting and up to 3/4 inch (19mm) maximum cutting thickness when operating at 220V.
• Dual Voltage Capability: Supports both 110V and 220V input power, with an included plug converter for easy switching.
• IGBT Inverter Technology: Utilizes advanced Insulated Gate Bipolar Transistor (IGBT) inverter technology for precise feedback control and strong, stable current output.
• Non-Touch Pilot Arc: Enables cutting without direct contact between the torch tip and the workpiece, reducing slag, improving cut quality, and extending consumable life. This feature is particularly useful for cutting rough, rusty, or painted surfaces.
• Versatile Metal Cutting: Suitable for cutting a wide range of metals, including stainless steel, alloy steel, mild steel, copper, and aluminum.
• Safety Protections: Equipped with overheating protection, pre-flow, and post-flow functions, along with rapid heat dissipation for enhanced safety and durability.

4. Package Contents

The ANDELI CUT-50 DS Plasma Cutter comes with the following components:

• Low Frequency Start Plasma Cutter (CUT-50 DS) x 1
• Plasma Cutter Torch x 1
• Gas Pipe (3M) x 1
• Hose Hoop x 2
• Electrode x 10
• Nozzle Shield x 10
• Hose Barb x 2
• Oil-water Separator x 1

5. Setup

Follow these steps to set up your plasma cutter:

1. Power Connection: Connect the power cord to a suitable 110V or 220V power outlet. Ensure the correct voltage is selected on the machine if applicable, or use the provided converter.
2. Air Compressor Connection: Connect an air compressor to the machine's air inlet. An air compressor with a minimum capacity of 800W and 50L is recommended for optimal performance.

Figure 5.1: Illustration of the recommended air compressor setup, emphasizing the need for an 800W, 50L compressor for efficient cutting.
3. Oil-Water Separator Installation: Install the oil-water separator to the air inlet to ensure clean, dry air supply to the plasma cutter. This prevents moisture from affecting cutting performance and damaging internal components.

6. Operating Instructions

Before operating, ensure all safety precautions are followed.

1. Power On: Turn on the main power switch located on the machine.
2. Set Current: Adjust the cutting current (Amperage) using the control knob on the front panel. The appropriate current depends on the material type and thickness. Refer to the cutting chart (if provided separately) for recommendations.
3. Prepare Workpiece: Ensure the workpiece is clean and free of excessive rust or paint. Secure the ground clamp firmly to the workpiece, ensuring good electrical contact.
4. Initiate Arc: Position the plasma torch approximately 1/8 to 1/4 inch (3-6mm) above the starting point of the cut. Press the torch trigger to initiate the pilot arc. The non-touch pilot arc will establish without needing to contact the metal.
5. Begin Cutting: Once the pilot arc is established, slowly move the torch along the desired cutting line. Maintain a consistent speed and standoff distance for a clean cut.
6. Monitor Cut Quality: Observe the molten metal and sparks. A proper cut will have a narrow kerf and minimal dross. Adjust cutting speed or current as needed.
7. Types of Materials: The CUT-50 DS is capable of cutting various metals, including angle steel, mild steel, sheet metal, and stainless steel.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your plasma cutter.

• Consumable Replacement: Regularly inspect and replace worn electrodes and nozzles. Worn consumables can lead to poor cut quality and reduced efficiency.
• Air Filter/Separator: Periodically drain any accumulated moisture from the oil-water separator. Clean or replace the filter element as needed to ensure a clean air supply.
• Cleaning: Keep the machine clean and free of dust and metal particles. Use compressed air to blow out internal components periodically, ensuring the machine is unplugged first.
• Cable Inspection: Inspect all cables and connections for signs of wear, cuts, or damage. Replace damaged cables immediately.
